Regional Breakdown

February in the High Plains had it all. From severe weather to snowstorms, nothing was off the table.

Snow continued to pile up in the Dakotas, Wyoming, and parts of Nebraska, leading to numerous impacts. Much of South Dakota was shut down due to the storm in late February, with up to 16 inches (40.64 cm) reported in Huron and 44 mph (71 km/h) wind gusts in Sioux Falls. Towards the end of the month, the first severe weather outbreak of the year occurred in parts of southern and eastern Kansas. A tornado occurred on the 26th, with a weak EF-0 causing damage to the town of Liberal. With the same storm system, the winds were exceptionally strong. A wind gust of 97 mph (156 km/h) was recorded near the town of Hodgeman, with numerous reports of wind damage that day.

While temperatures were close to normal for the southern part of the region in part to a cold start, the rest of the month was predominantly above-normal. This has led plants to begin blooming much earlier than expected. The plants that have bloomed are highly susceptible to freezing temperatures that may still occur.

Precipitation and Water Resources

Precipitation was spotty this past month, however, the precipitation that did occur was well above-normal. Both ends of the spectrum occurred this month with near-record dryness and wetness. Despite still being meteorological winter, severe weather was present this month.

Winter storms continued to impact the northern parts of the region, with Wyoming and the Dakotas significantly impacted. Rawlins, Wyoming, recorded their 2nd wettest month with 1.67 inches (42.42 cm). Although the official station does not track snowfall, a nearby station reported over 34 inches (86.36 cm) of snow in February. Bismarck, North Dakota, and Huron, South Dakota, ranked 8th snowiest with over 15 inches (38.10 cm) in both locations. Opposite of this wetness, Akron, Colorado, was bone dry, recording a mere trace of precipitation this month to tie for the driest.

With the conclusion of February, the meteorological winter has ended. In a complete turnaround from last year, many places recorded near-record precipitation and snowfall. Multiple locations in Nebraska and Wyoming recorded their wettest and snowiest winters. Valentine, Nebraska crushed its previous snow record by nearly 14 inches (35.56 cm), with 56.4 inches
(143.26 cm) observed.

As of March 1st, mountain snowpack continued to be in great shape. Most basins are slightly above normal, outside the South Platte Basin in Wyoming and the Arkansas River Basin in Colorado. Snowpack is deep for spring runoff, which is beneficial to the current drought conditions.

Temperatures

Temperatures this past month were, for the most part, near to below normal for the region. Parts of western Wyoming and northwestern Colorado were 9 degrees F (5 degrees C) or more below normal.

Temperatures were well below normal across parts of Wyoming, with Rawlins and Lander ranking as the 10th coldest on record. The town of Farson had a brutal month, with an average temperature of 1.6 degrees F (-16.9 degrees C). The high temperature only surpassed 32 degrees F (0 degrees C) in only two days in February.

While temperatures were chilly in Wyoming, Kansas had milder temperatures. Many locations recorded ten or more days of 60 degrees F (15.6 degrees C), while the town of Lakin reached 80 degrees F (26.7 degrees C) on the 27th.

Drought Conditions

Drought improvement continued into February in response to the significant wetness this winter. While conditions did slightly deteriorate this past month, it was very isolated. Overall, there was a 2.4 percent decrease in D0 to D4 (abnormally dry to exceptional drought conditions).

The continuous onslaught of winter storms has greatly improved the drought situation across the central and northern parts of the region. Both South Dakota and Wyoming observed a nearly 11 percent decrease in D2 to D4 (severe to exceptional drought) this past month, while Kansas experienced an 11 percent reduction in D0-D4. Elsewhere in the region, other improvements and degradation were observed. According to the Climate Prediction Center’s U.S. Monthly Drought Outlook for March, drought conditions will improve in eastern South Dakota and western Wyoming.

Regional Breakdown

2022 will be remembered as the year of unusually high winds in the High Plains. After beginning the year with near-record strong winds, the final month brought similar conditions.

Early in December, winds gusted over 40 mph (64.4 km/h) in northwestern Kansas. With how significant the drought is in that area; large amounts of dust were picked up by the strong winds. The blowing dust led to a multi-vehicle accident and unfortunately, one person perished.

Winds were not only prevalent at the beginning of the month but also contributed to likely one of the coldest spells on record for the region. An intense cold front moved through on the 21st, with many places dropping 40 degrees F (22.2 degrees C) in under an hour. This arctic outbreak not only brought cold temperatures but also extreme winds. Wind chills surpassed –70 degrees F (-56.7 degrees C) in Wyoming, while the rest of the region saw wind chills between –40 and –50 degrees F (-40 and –45.6 degrees C) due wind gusts well over 50 mph (80.5 km/h) in some places. Although wind chills records are hard to verify, many places likely experienced their record coldest wind chill. This system also brought snow, with much of the region experiencing a white Christmas this year.

Precipitation and Water Resources

December precipitation was much above-normal for the northern part of the region due to several winter storms, however, the drought-stricken areas along the Front Range of the Rockies and western Kansas missed this beneficial precipitation again. Many locations recorded their top 10 wettest
and snowiest months on record.

With mounting dryness from the past several months, these winter storms could not have been more beneficial. Northern Nebraska benefited greatly, with Chadron and Valentine observing their record-wettest month. Valentine also recorded their 3rd snowiest month and nearly broke the record, with 22.3 inches (56.64 cm) of snow. Across the Dakotas, numerous locations observed near-record precipitation and snowfall. Pierre and Sisseton ranked in the top 5 wettest and snowiest, while the majority of South Dakota ranked in the top 10 wettest. Bismarck, North Dakota followed up a very snowy November by recording their 2nd December, with 30 inches (76.2 cm) of snow falling.

At the beginning of the month, much of the region was near record lows for soil moisture. While the southern part of the region missed out, much of the region greatly benefited from the precipitation this past month.

While it is still early into the season, the mountain snowpack is in good shape. The majority of the basins are at or near average. This is favorable for improving streamflow conditions, as they are incredibly low throughout the drought-stricken southern Plains. The Corps of Engineers announced
that releases from Gavins Point Dam will reach wintertime levels by mid-December.

precipitation in inches (bottom) for December 2022. These maps are produced by HPRCC and can be found on the Current Climate Summary
Maps page at: http://hprcc.unl.edu/maps/current

Temperatures

The first half of the month began with warmer temperatures, however, things rapidly changed in the back half. A vigorous low-pressure system led to significant temperature drops and record cold. Overall, most of the region ended with below to well below normal temperatures.

After enjoying normal to above-normal temperatures for the first part of the month, the region experienced dangerously cold temperatures and wind chills. Many locations experienced record temperature drops on the afternoon of the 21st after a remarkable cold front advanced across the central United States. Cheyenne, Wyoming dropped 40 degrees F (22.2 degrees C) from 43 degrees F (6.1 degrees C) to 3 degrees F (-16.1 degrees C) in just 30 minutes, beating the previous record of 37 degrees F (20.6 degrees C) in an hour. Temperatures continued to drop, with the thermometer falling a total of 51 degrees F (28.3 degrees C) in two hours. Combined with high winds, dangerous and record wind chills were present across much of the region for the next few days. Temperatures rebounded, with Cheyenne reaching 57 degrees F (13.9 degrees C) on the 27th.

Drought Conditions

The record to near-record wetness across the northern part of the region eased drought conditions. In the southern portions, the precipitation deficits continued to increase and further elevated the situation. Overall, there were minimal changes in D0 to D4 (abnormally dry to exceptional drought conditions).

The multiple winter storms led to large-scale improvements in the Dakotas. South Dakota observed a 26 percent decrease in D1-D4 (moderate to exceptional drought) after multiple locations in the state were in the top 10 snowiest December. The area coverage of extreme drought (D3) was
reduced by almost 10 percent and is now limited to a small portion in the southeastern part of the state. While D4 was trimmed slightly in southeastern Kansas, it was expanded in the northwestern part of the state and is now connected to the area of D4 in southwestern Nebraska. Elsewhere in the region, other improvements and degradation were observed.

Climate Outlooks

According to the Climate Prediction Center, La Niña conditions are likely to continue through the end of the year. A La Niña advisory is currently in effect. For more information, visit  https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/lanina/enso_evolution-status-fcsts-web.pdf

The National Weather Service’s long-range flood
outlook indicates a low probability of Minor Flooding in eastern Kansas through February. According to the National Interagency Fire Center (NIFC), fire potential will be limited across the region through next year.

Temperature

The three-month temperature outlook shows an increased chance of above-normal temperatures in the southern part of the United States, while below-normal temperatures are favored in the northwestern part. Across the High Plains there are equal chances of above-, below-, and near-normal temperatures across much of the region. The Dakotas and parts of Wyoming have increased chances of below-normal temperatures.

Precipitation

The outlook for the next three months indicates below-normal precipitation across central parts of the United States. Across the High Plains, there are equal chances of above-, below-, and near normal precipitation in North Dakota. The rest of the region has increased chances of below-normal precipitation.

Drought

The U.S Seasonal Drought Outlook released on December 15th indicates that drought conditions will likely improve across the northern part of the region. Opposite of this, development is likely in southern Colorado.

Regional Breakdown

November brought relief from the continued above-normal temperatures; however, precipitation was still below-normal for much of the region. Drought conditions will likely continue through the winter, which will affect agricultural production.

A lone bright spot in agriculture was the optimal weather conditions allowed for a rapid harvest this year. Minimal precipitation and favorable temperatures allowed farmers to harvest unimpeded this year. These conditions, however, were not helpful for the early stages of winter wheat production. At the end of November, winter wheat was in the worst condition in the past 20 years. Nearly 40 percent is rated poor to very poor in Colorado, Kansas, and Nebraska. The continued dryness this fall has amplified the need for snow cover and moisture, or winter wheat will struggle again in 2023.

The first significant winter storm impacted the northern part of the region starting on November 9th, with heavy snow in North Dakota and an ice storm in South Dakota. Much of North Dakota shut down after a foot of snow impacted parts of the state. Bismarck received 17 inches (43.18 cm) on the 10th, the second-highest daily snowfall amount on record. In South Dakota, ice was a significant problem with places receiving up to 0.75 inches. The cooler temperatures that followed for much of the month allowed the ice to linger until Thanksgiving week.

Precipitation and Water Resources

Precipitation was spotty this past month, with pockets of well-above-normal precipitation present and much below-normal. Parts of North Dakota and Kansas received much-needed precipitation, which helped improve drought conditions.

Western Kansas and the front range of Colorado were incredibly dry this past month, with much of the area recording less than 0.10 inches (2.54 mm) of precipitation. Akron, Colorado tied for its 3rd driest November on record, with a meager 0.02 inches (0.51 mm) of precipitation. Goodland, Kansas also ranked 10th driest, with only 0.03 inches (0.76 mm) observed.

With the end of meteorological fall, many locations ranked in the top 10 driest falls. The Dakotas were among the driest of all locations. Grand Forks and Fargo, North Dakota ranked 4th driest on record, with both locations observing less than 1.50 inches (3.81 cm) of precipitation. In South Dakota, Huron, Aberdeen, and Rapid City ranked in the top 4, with only Rapid City recording more than 1 inch (2.54 cm) of precipitation this fall. Nebraska was also very dry, with Chadron, Grand Island, Lincoln, and Omaha ranking in the top 10 driest.

Temperatures

After multiple months of warm temperatures, the region finally cooled off. Much of the region was near to slightly below normal, while the northwestern portion was well below normal. Parts of Wyoming were nearly 10 degrees F (5.6 degrees C) below normal this past month.

Despite the overall cooler temperatures, warm temperatures lingered into the beginning of the month. Temperatures eclipsed 80 degrees F (26.7 degrees C) in Kansas several days during the beginning of the month, only to rapidly cool down. Departures rapidly went from over 20 degrees F above normal to 20 degrees below normal. The dramatic swings were limited to the first half of the month, with the back half of November near normal temperatures.

On the opposite end of the spectrum parts of Yellowstone National Park in Wyoming dropped to –30 degrees F (-34.4 degrees C) on the 19th. Multiple days this month reached –20 degrees F (-28.9 degrees C) in Yellowstone.

Drought Conditions

Cooler temperatures this past month helped limit the overall expansion of drought conditions. While precipitation was below normal in many places, the areas that did receive some greatly benefited from it. Overall, the region observed a 2 percent decrease in D0 to D4 (abnormally dry to exceptional drought conditions).

With the meteorological fall coming to an end, the drought situation remains dire in the region. November offered some relief for parts of Kansas and the Dakotas, however, conditions further deteriorated in Nebraska. Over 85 percent of the state is currently experiencing D2-D4 (severe to exceptional drought). The dry conditions plaguing the state have led to a 25 percent increase since the beginning of September. While extreme drought (D3) conditions have doubled in the state since the beginning of October, with nearly 60 percent of the state under these conditions. Elsewhere in the region, other improvements and degradation were observed.

Climate Outlooks

The National Weather Service’s long-range flood outlook indicates a low probability of Minor Flooding in eastern Kansas through February. According to the National Interagency Fire Center (NIFC), fire potential will be limited across the region through next year.

Temperature

The three-month temperature outlook shows an increased chance of above-normal temperatures in the southern part of the United States, while below normal temperatures are favored in the northwestern part. Across the High Plains, there are equal chances of above-, below-, and near-normal
temperatures across much of the region. The Dakotas and parts of Wyoming have increased chances of below-normal temperatures.

Precipitation

The outlook for the next three months indicates below-normal precipitation across the southern parts of the United States and above-normal chances across the northern portions. Above-normal precipitation is slightly favored in parts of the Dakotas and Wyoming. Drought-stricken western Kansas and southern Colorado slightly lean towards below-normal precipitation.

Drought

The U.S Seasonal Drought Outlook released on November 17th indicates that improvements will occur in western Wyoming, while development should occur in southern Colorado. Drought should remain entrenched throughout much of the region through winter.

Warm and Dry Start to Fall

October was a month with a flavor of every season, with everything from severe storms to heavy snow across the region. Drought-stricken Kansas was nearly bone-dry, while western Colorado observed above-normal precipitation and up to 22 inches (56 cm) of snow in some places. Temperatures were above normal for much of the region throughout the month.

A vigorous low-pressure system trekked across the region on the 23rd, causing numerous impacts in multiple states. Severe storms impacted northeastern Nebraska and southeastern South Dakota, with 2-inch hail and 70 miles per hour (113 km/h) winds reported. Simultaneously, snow fell in western parts of the Dakotas and Wyoming. High winds also wreaked havoc in the southern part of the region. With ample fuel available, these winds sparked several large fires in Kansas and Nebraska. Several towns were evacuated in Nebraska due to the danger, with a large fire raging just south of Lincoln. The western parts of both states also experienced large amounts of blowing dust. The winds, unfortunately, led to two deaths in Colorado after their kayak flipped over due to the high waves.

Precipitation

The region was extremely dry this past month, with large portions receiving less than 0.10 inches (2.54 mm) of precipitation. The western parts of Colorado and North Dakota received above-normal precipitation, however, the drought-afflicted areas in the region were bone dry.

Precipitation has been very hard to come by in southwestern Kansas this year, and October did no favors. Dodge City tied their driest month on record, with only trace precipitation. Through the end of October, Dodge City is nearly 9 inches below its normal precipitation. Many locations across Kansas and Nebraska currently rank in the top 10 driest through the end of October. Norfolk, Nebraska, recorded its driest January-October, with this year being over 0.50 inches (12.70 mm) drier than in 2012.

In South Dakota, Aberdeen recorded back-to-back top 10 driest months. Only 0.21 inches (5.34 mm) of precipitation has occurred, ranking 2nd driest for September-October. The lack of precipitation and warmer temperatures have led to a rapid expansion of drought conditions in that part of the state.

Streamflow Update

Streamflow across much of Kansas and Nebraska was below-normal at the
end of the month. Runoff north of Sioux City was 60% of normal at the
end of October due to the long-term effects of drought. Mountain snowpack is near normal throughout the Rockies except for southeastern Wyoming.

Temperatures

Overall, October was unusually warm throughout the region. Much of the region was above normal, with places up to 6 degrees F (3.3 C) above their normal temperature.

An unseasonably warm period impacted the region on October 21-23. Many locations set daily records, with some places reaching their warmest temperature on record through the end of the year. A total of 232 daily temperature records were broken during this period throughout the region. In Nebraska, Lincoln and Grand Island tied their warmest temperature on record for this late in the year. Another notable statistic about this heat wave is the number of 80 degrees (26.7 degrees C) plus days that Lincoln has observed this year. A whopping 142 days this year have reached that temperature, which is the most on record. Further south in Kansas, Russell reached 93 degrees F (33.9 degrees C) on the 23rd, surpassing their previous warmest temperature for the rest of the year by 4 degrees F (2.2 degrees C).

Above: Daily temperatures for October 2022, along with extremes and normals values in Grand Island, Nebraska.

Drought Conditions

Drought conditions rapidly expanded this past month, with nearly 76 percent of the region experiencing moderate to exceptional (D1-D4) conditions. The Dakotas observed the largest increases in drought coverage, with both states increasing by over 20 percent.

As the year is nearly over, Kansas and Nebraska are in rough shape heading toward winter. In just October alone, Nebraska experienced a 21 percent increase in extreme drought (D3), and Kansas recorded nearly a 13 percent increase in exceptional drought (D4). Both states are in large precipitation deficits and will likely not see much improvement over the winter. In the meantime, not only did drought rapidly expanded in the Dakotas, but it also intensified quickly, with both states recording a 25 percent increase in severe drought (D2). Elsewhere in the region, other improvements and degradation were observed.

Climate Outlooks

The National Weather Service’s long-range flood outlook indicates a low probability of Minor Flooding in eastern Kansas through January. According to the National Interagency Fire Center (NIFC), fire potential will be limited across the region through next year.

Temperature

The three-month temperature outlook shows an increased chance of below-normal temperatures across the northern United States, while above-normal temperatures are favored for the southern states. Increased chances of below-normal temperatures are present in the Dakotas and the northern portions of Wyoming and Nebraska. Above-normal temperatures are slightly favored in western Colorado.

Warm and Dry Start to Fall

The first month of meteorological fall was disappointing for much of the region. Instead of bringing cooler temperatures and much-needed moisture, the trend of warm and dry conditions, unfortunately, dominated the region. The dryness that had been limited to Kansas and Nebraska spread into the Dakotas. Drought conditions rapidly spread across North Dakota in response to minimal precipitation.

Among the more interesting impacts of the drought this year occurred outside of Hays, Kansas. The nearby Ellis City Lake declared a public fish salvage in response to the extremely low water levels. With levels dangerously low, the fish are in danger of using oxygen too quickly. All catch limits and size rules on fish within the lake are removed, with any means of catch acceptable. The state of Kansas fears all the fish will die, resulting in them having to completely restart the aquatic population.

The dire situation in southeastern Kansas led to serious consequences for one town. The town of Caney declared a water emergency in mid-September in response to low well levels. Water usage for outdoor purposes is banned, with the potential for citations or disconnections for residents. This part of Kansas rapidly dried out in the summer months, with September offering no relief.

Precipitation

Much of the High Plains was dry in September, with the majority of the Dakotas receiving less than an inch of precipitation. Drought-stricken areas in the western parts of Kansas and Nebraska received some precipitation, but not nearly enough to improve drought conditions.

After observing near-normal to above-normal precipitation for much of this year, North Dakota was nearly bone-dry in September. Dickinson observed their driest September on record, with a paltry 0.07 inches (1.78 mm) of precipitation. In South Dakota, Sisseton fared slightly better with 0.08 inches (2.03 mm) to rank 2nd driest. Aberdeen and Pierre recorded less than 0.15 inches (3.81 mm) in September to rank in the top 10 driest.

Looking further back, many locations in Kansas and Nebraska currently rank in the top 10 driest year-to-date. Arguably the driest place in the region is Garden City, Kansas. Only 5.01 inches (12.73 cm) of precipitation has fallen this year, nearly 2 inches (5.08 cm) below the previous record. In southwestern Nebraska, several locations are in the midst of their driest year-to-date. Most notably is Ogallala, which is the site of Lake McConaughy. Through the end of September, only a meager 5.74 inches (14.58 cm) of precipitation has been observed, well below the normal of 17.29 inches (43.92 cm).

Streamflow Update

Outside the areas impacted by drought, streamflow throughout the region was generally in good shape. Flooding continues along the James River in South Dakota resulted from heavy precipitation in previous months. Conditions in southwestern Nebraska and western Kansas continued to be much below normal. August runoff north of Sioux City was 62% of normal due to the long-term effects of drought.

Temperatures

September temperatures were well above-normal across the region, with numerous locations ranking in the top 10 warmest months on record. Much of the region experienced 2 to 4 degrees F (1.1 to 2.2 degrees C) above normal, while small areas of 6 to 8 degrees F (3.3 to 4.4 degrees C) above normal temperatures were also present.

The warmest areas in the region have been eastern Wyoming and western Nebraska for the past few months. This area experienced record to near-record warmth this summer, with the trend continuing into the beginning of fall. In Wyoming, Cheyenne, Laramie, and Rawlins all ranked 2nd warmest. While in Nebraska, Scottsbluff ranked 2nd, and Chadron Station Spotlight: Chadron, Nebraska Above: Daily temperatures for September 2022, along with extremes and normals values in Chadron, Nebraska. was the warmest on record with an average temperature of 67.7 degrees F (19.8 degrees C).

Colorado was also extremely warm this past month as well. Alamosa averaged 59.9 degrees F (15.5 degrees C) to rank warmest, while Denver ranked 3rd. Other locations such as Grand Junction, Pueblo, and Colorado Springs, also ranked in the top 5.

Above: Daily temperatures for September 2022, along with extremes and
normals values in Chadron, Nebraska.

Drought Conditions

Drought not only re-appeared but rapidly spread across North Dakota after a very dry month. Outside of areas in Colorado and Wyoming, there were minimal improvements. Overall, there was a 16 percent increase in moderate to exceptional (D1-D4) this September. At the beginning of September, less than 1 percent of North Dakota was under drought conditions. By the end of the month, 72 percent of the state was experiencing drought. The lack of precipitation in the state in the past 60 days prompted the rapid expansion. Western Kansas has been the epicenter of the drought for most of the year for the state, but the southern part of the state has rapidly deteriorated in recent months. Currently, 25 percent of the state is in exceptional drought (D4). Elsewhere in the region, other improvements and degradation were observed. According to the Climate Prediction Center’s U.S. Monthly Drought Outlook for October, drought development is likely across parts of Kansas, Nebraska, and South Dakota.

Climate Outlooks

The National Weather Service’s long-range flood outlook indicates a low probability of Minor Flooding in eastern Kansas through December. According to the National Interagency Fire Center (NIFC), fire potential will be limited across the region through next year.

Temperature

The three-month temperature outlook shows an increased chance of above-normal temperatures across the majority of the United States. Equal chances of above-, below-, and near-normal are present in the Dakotas, otherwise, above-normal temperatures are favored.

Precipitation

The outlook for the next three months indicates below-normal precipitation across central parts of the United States. Across the High Plains, there are equal chances of above-, below-, and near-normal precipitation in the Dakotas and northern Wyoming. The rest of the region has increased chances of below-normal precipitation.

Drought

The U.S Seasonal Drought Outlook released on September 30th indicates drought conditions are expected to develop in Colorado, Kansas, Nebraska, and South Dakota.

Hot and Dry Conditions Continue into July

The hot and dry conditions that started at the end of June carried over into July. Temperatures were well above normal for much of the month before finally cooling off. While precipitation was spotty, the amounts were plentiful in areas that received it.

The ongoing drought has taken its toll on agricultural conditions, particularly in Kansas and Nebraska. Corn was rated 33 percent and 22 percent poor to very poor, respectively. Farmers in western Kansas have started filing for crop insurance due to poor expected yields. Sorghum is a fairly drought-resistant crop, however, over 30 percent is rated poor to very poor in both states. Pasture and range conditions are also struggling, with over 30 percent rated very poor in both states. With a lack of feed, there has been a surge in cattle sell-offs.

Temperatures this month were excruciatingly hot, with several locations in the southern part of the region breaking all-time average temperature records. The following stations all have data going back to the 1800s. In Colorado, Castle Rock and Fort Collins surpassed their records on the 19th, while Fort Morgan did so on the 2nd. Scottsbluff, Nebraska broke its record on the 18th and Dodge
City had an average temperature of 94.5 degrees (34.7 degrees C) on the 15th to tie the record.

Precipitation

Precipitation across the region was sporadic this month, however, locations that did receive rainfall in July were well above-normal. Drought-afflicted areas such as southwestern Nebraska and western Kansas continued to be below normal.

Precipitation was plentiful in the northern parts of the region, with several locations ranking in the top 10 wettest Julys. Huron, South Dakota, received 6.52 inches (16.56 cm) ranking 2nd wettest, while Dickinson,
North Dakota, recorded 4.39 inches (11.15 cm) to place 4th. The southwest monsoon brought much-needed precipitation, with 5.35 inches (13.59 cm) observed in Colorado Springs, Colorado, to rank 5th wettest.

It was a relatively quiet month for severe storms for the region, aside from another derecho in South Dakota on the 5th of July. Much of the precipitation in Huron occurred from this storm, with 5 inches (12.7 cm) re- ported by a nearby CoCoRaHS observer. Notable impacts included a 99 mph (159 km/h) wind gust near Howard and the presence of ominous green skies over Sioux Falls.

Streamflow Update

Streamflow throughout the region was generally in good shape. Heavy precipitation led conditions in northeastern South Dakota and eastern North Dakota to have much above normal streamflow with some flooding expected. Conditions in southwestern Nebraska and western Kansas continued to be much below normal. Annual runoff above Sioux City is 80% percent of normal due to the long-term effects of drought.

Temperatures

The trend of above-normal temperatures continued into July. Much of the region experienced temperatures 2 to 4 degrees F (1.1 and 2.2 degrees C) above normal. Temperatures were scorching hot throughout most of July, with relief finally coming towards the end of the month.

Once again, western Kansas experienced the warmest temperatures throughout the region. Many days were well above 100 degrees (56 degrees C), with a station near Ashland recording 20 days above 100 degrees F. In central South Dakota, temperatures reached an incredible 114 degrees F (63 degrees C) on the 18th.

Along the front range of the Rockies, Denver recorded its 2nd warmest July and the 2nd warmest month on record. The average temperature in July was 78 degrees F (43 degrees C). Nearby Cheyenne, Wyoming, observed their 4th warmest July on record with an average temperature of 73.4 degrees F (40.8 degrees C). This also ranked as the 4^th warmest month on record.

Above: Daily temperatures for July 2022, along with extremes and
normals values in Ashland, Kansas.

Drought Conditions

Warm and dry conditions throughout much of the month led to the intensification of drought conditions in the southern part of the region. Overall, there was a 3 percent increase in moderate to exceptional (D1-D4) drought in July. North Dakota continues to remain drought-free.

Numerous days of extreme heat and a lack of precipitation led to a significant increase in drought conditions across western Kansas. Most notably, D4 increased 7 percent by the end of July and 25 percent of the state is experiencing extreme to exceptional (D3-D4) drought. Nebraska and Wyoming also experienced intensification, with D3 conditions increasing 5 and 3 percent, respectively. Drought conditions did improve in the southwestern parts of Colorado, however, they deteriorated along the Front Range. Elsewhere in the region, other improvements and degradation were observed. According to the Climate Prediction Center’s U.S. Monthly Drought Outlook for August, drought improvement is likely across much of Colorado, western Kansas, and southern Wyoming, while development is likely in eastern Nebraska.

Climate Outlooks

The National Weather Service’s long-range flood outlook indicates a high chance of Major Flooding in northeastern South Dakota through September. According to the National Interagency Fire Center (NIFC), fire potential will be limited to western Nebraska, western South Dakota, and eastern Wyoming through November.

Temperature

The three-month temperature outlook shows an increased chance of above-normal temperatures across the majority of the United States. Equal chances of above-, below-, and near-normal are present in North Dakota and northern South Dakota, otherwise, above-normal temperatures are favored.

Precipitation

The outlook for the next three months indicates below-normal precipitation across central parts of the United States. Across the High Plains there are equal chances of above-, below-, and near-normal precipitation in North Dakota. The rest of the region has increased chances of below-normal precipitation.

Drought

The U.S Seasonal Drought Outlook released on June 30^th indicates drought conditions are expected to improve in Colorado and southern Wyoming. Opposite of this, drought development is likely in parts of South Dakota, Nebraska, and Kansas.

Warm and Dry Conditions Prevailed

Summer-like conditions took hold in the High Plains towards the middle of the month, with above-normal temperatures and below-normal precipitation across the region. Drought conditions initially were improving towards the beginning of the month due to cool temperatures and above-normal precipitation, however, the prevailing hot and dry conditions led to intensification at the end of the month.

Temperatures were extremely hot in western Kansas this month, which led to many cattle deaths. A rapid increase in temperatures from 80 degrees F (26.7 degrees C) on the 9th to 104 degrees F (40 degrees C) on the 11th led over 2,000 cattle to perish. This extreme swing combined with other factors such as high
overnight temperatures and minimal wind did not give time for cattle to adjust to conditions or to cool off.

Hailstorms were an issue for Nebraska this month, with the state having several destructive storms early in the month. Crops have been ravaged by the storms, while millions of dollars in damage has been caused to homes and vehicles. Two towns in the central part of the state have nearly 90 to 100 percent of homes significantly damaged. The most damaging storm was on the 14th when 115 mph (185 km/h) wind-driven hail of 1 to 3 inches impacted cities across the eastern portions of the state.

Heavy precipitation in northern Wyoming and the rapid melting of snowpack led to record flooding in Yellowstone National Park. Bridges and roads were washed out, while several homes were swept away by the waters. The
damage caused the park to close for over a week, with only the southern entrances reopened by the end of the month.

Precipitation

June precipitation was well below-normal for many
parts of the region, most notably in Wyoming and western Nebraska. Contrary to this, the Southwest monsoon season began early this year, with much-needed precipitation in the southern and western parts of Colorado.

Much of Wyoming received less than an inch (25.4 mm)
of precipitation this month, with the central part of the state nearly bone dry. Lander recorded trace amounts of precipitation which ties both 1956 and 1971 for driest on record. Nearby, Casper received 0.21 inches (5.34 mm) to rank 7th driest. This dryness stretched into western Nebraska, with North Platte and Chadron ranking 2nd and 3rd driest, after 0.43 and 0.84 inches (10.92 and 21.34 mm) of precipitation, respectively.

Precipitation in South Dakota was mixed, with both the top 10 driest and wettest months recorded in the state. In the northeastern part of the state, Sisseton and Aberdeen ranked 4th and 6th driest, respectively. In the central part of the state, however, Pierre observed their 6th wettest June on
record, with 6.34 inches (16.10 cm) of precipitation.

Severe weather was near normal to slightly above average for the region in terms of warnings issued by the National Weather Service. Large hail was observed on numerous days across the region, with several days having reports of 4-inch (10.16 cm) plus diameter hail. A dangerous storm in Nebraska on the 11th dropped extremely large hailstones in the 5-inch (12.7 cm) range.

Streamflow Update

Upper Missouri River Basin mountain snowpack completely melted in June. The U.S. Army Corps of Engineers Missouri River Water Management Division announced that they will increase the navigation flow level, with the releases from Gavins Point being adjusted. Streamflows in drought-afflicted areas such
as western Kansas and Nebraska were near record lows. However, streamflows fared much better in North Dakota and the eastern portions of South Dakota and Kansas, where precipitation has been more plentiful.

Temperatures

June was warm for much of the region, with several locations observing their top 10 warmest months on record. This was particularly noticeable during
the middle of the month when numerous temperature records were broken across the region. Towards the beginning of the month, several daily low records were broken in the western part of the region.

Temperatures were well above normal in eastern South Dakota this past month. Sisseton recorded its 3rd warmest month with temperatures averaging 73.6 degrees F (23. 1 degrees C), while Sioux Falls ranked 10th with an average temperature of 72.5 degrees F (22.5 degrees C). In western Nebraska, McCook and North Platte ranked in the top 10 with numerous warm days.

The heat wave in the middle of the month led to scorching hot temperatures. Atwood, Kansas observed a high temperature of 111 degrees F (43.9 degrees C) while McCook, Nebraska recorded a high of 109 degrees F (42.8 degrees C) on the 14th. Several locations in western Kansas observed over ten days of 100-degree F (37.8 degrees C) plus temperatures.

normals values in Sisseton, South Dakota.

Drought Conditions

A wet start to the month led to improvements, however, dry and windy conditions prevailed towards the end. The High Plains region observed a 6 percent decrease in moderate to exceptional (D1-D4) drought in June.
North Dakota remained drought-free the entire month.

The monsoon season began in the southwest towards
the end of the month, leading to improvements in Colorado. Severe drought (D2) was reduced by 12 percent due to this beneficial precipitation. South Dakota and Wyoming observed a 25 percent reduction to D1 after
receiving above-normal precipitation. Conditions improved slightly in southwestern Kansas, however, D4 remained entrenched in the area. A large swath of extreme drought (D3) was introduced at the end of the month along the Colorado and Nebraska border. Elsewhere in the region, other improvements and degradation were observed. According to the Climate Prediction Center’s U.S. Monthly Drought Outlook for July, drought conditions are likely to develop in parts of Colorado, Kansas, Nebraska, and South Dakota.

Climate Outlooks

According to the Climate Prediction Center, La Niña conditions are likely to continue through the end of the year. A La Niña advisory is currently in effect. For more information, visit https://www.cpc.ncep.noaa.gov/products/analysis_ monitoring/lanina/enso_evolution-status-fcsts-web.pdf

The National Weather Service’s long-range flood outlook through July indicates a high chance of Major Flooding in northeastern South Dakota through August. According to the National Interagency Fire Center (NIFC), fire potential will be limited through October.
