Regional Breakdown

While snow continued to impact the northern states in March, precipitation was notably absent for much of the High Plains. Cooler temperatures helped with drought conditions; however, many places desperately need moisture this spring.


As the significant drought affecting Kansas enters the second year, a number of impacts are becoming apparent. Winter wheat is in incredibly poor shape, with some places not having meaningful precipitation in nearly 200 days. Fields are already being evaluated by insurance adjusters and being adjusted out, despite no wheat emerging. Farmers will be forced to find ways to hold soil in place in the coming months, as blowing dust has been an issue over the past year. The groundwater has been depleted, with water levels dropping nearly three feet near Garden City. A very unusual impact comes from the Kansas Department of Wildlife and Parks. Game Wardens within the state are seeing increased numbers of coyotes in towns this year due to the extreme drought conditions. The dry conditions have caused them to become desperate for sources of food and water.


After a quiet winter for wildfires, conditions rapidly became conducive for fires late in the month. Two separate fires broke out in Colorado on the 30th, with the town of Simla being evacuated after the flames poised a threat to the public.

Precipitation and Water Resources

Precipitation was once again spotty this month. Several winter storms impacted the Dakotas, however, much of Kansas and Nebraska were bone dry.


Southwestern Kansas has been on the short end of the stick when it comes to precipitation for the past year, and March was no exception. Many places received less than 0.10 inches (2.54 mm) of precipitation, including Hays, Garden City, and Great Bend. Since the start of 2023, numerous locations have received less than 0.50 inches (12.7 mm) of precipitation. After record to near-record dryness last year, the situation continues to become dire and dire each month.


The onslaught of snowstorms in the Dakotas carried over into March. Blizzards continued to ravage both states, with record to near-record snowfall this month. Sisseton, South Dakota measured 31.3 inches (79.5 cm) of snow which set the record for March. This large amount of snow also propelled them to observe their snowiest January to March, with 48.5 inches (123.2 cm) of snow. Pierre ranked second after 19.1 inches (48.5 cm) of snow, but well short of the record at 31.8 inches (80.8 cm) set in 1975. Ranking third snowiest includes Aberdeen and Fargo, North Dakota.


As winter has ended and spring begins, snowpack is in great shape. At the end of March, the majority of the Dakotas and Wyoming have snow on the ground. Mountain snowpack is above normal for most basins, which should greatly benefit the water supply. Streamflow is well below normal across southern Nebraska and most of Kansas at the beginning of April.

Temperatures

March was chilly, particularly in parts of the Dakotas, Colorado, and Wyoming. Departures were up to 20 degrees F (11.1 degrees C) below normal in those states, with many locations ranking in the top 10 coldest. Temperatures were slightly below-normal for the rest of the region.


North Dakota was brutally cold, with the highest average temperature in the state being 20.6 degrees F (-6.3 degrees C) in the southwestern part of the state. The town of Mayville was the coldest place in the state, with an average temperature of 9.3 degrees F (-12.6 degrees C), which was also the coldest March on record for that station. Nearby Grand Forks observed their 3rd coldest March, with an average temperature of 12.6 degrees F (-10.8 degrees C). Other notable locations such as Bismarck, Dickinson, and Williston also ranked in the top 10.


Portions of Wyoming have been exceptionally cold in 2023. Casper and Rawlins recorded their 4th coldest January to March, while Lander was the coldest on record. The average temperature in the past three months was a meager 16.4 degrees F (-8.7 degrees C).

Drought Conditions

Drought conditions improved this month, primarily in North Dakota. Conditions did degrade in the southern portions of the region after minimal precipitation occurred. Overall, there was a 3 percent decrease in D0 to D4 (abnormally dry to exceptional drought conditions).


After a bitterly cold and wet month, North Dakota experienced a 30 percent reduction in D1- D4 (moderate to exceptional). Despite the reduction in drought conditions, there was a minimal reduction in abnormally dry conditions with 95 percent of the state still observing D0-D4. While drought still remains entrenched in Nebraska, D3 to D4 (extreme to exceptional) was reduced by eight percent. 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 Wyoming, South Dakota, and parts of Nebraska and North Dakota.

Regional Breakdown

After below-normal precipitation in the High Plains for most of 2022, the new year began with record-breaking wetness. Many locations in the central part of the region eclipsed or ranked in the top 10 for both precipitation and snowfall.

The winter of 2022-2023 has been very beneficial to parts of Wyoming, western Nebraska, eastern South Dakota, and northeastern Colorado. Valentine, Nebraska has already recorded their wettest and snowiest winter on record, with nearly 10 inches (25.4 cm) of snowfall and 1 inch (2.54 mm) of precipitation more than the previous record. While this wetness has impacted places affected by drought in 2022, the changes in drought conditions have been slow to improve due to the severity.

Strong winds once again reared their head, this time combining with the winter weather. Multiple times during the month, both I-80 and I-25 were closed in Wyoming due to high winds and winter storms, or a combination of both. Several large accidents took place during the month, with the largest being a 44-vehicle pileup on the 28th to the west of Laramie.

Precipitation and Water Resources

Several winter storms impacted the drought-stricken central part of the region this past month, leading to numerous precipitation records being broken. While many locations were above 200 percent of their normal precipitation, North Dakota and the northern portions of South Dakota missed out on this beneficial precipitation.

Records were not only broken but shattered in parts of Nebraska and Wyoming. In Nebraska, monthly precipitation records were eclipsed by nearly 0.50 inches (12.70 mm) in Scottsbluff and Valentine, while many other locations like North Platte and Grand Island ranked in the top 10. The state of Wyoming experienced the brunt of these storms, with Casper, Lander, Riverton, and Rawlins surpassing their record. On the opposite end of the spectrum, North Dakota missed out, and Grand Forks ranked in the top 10 driest (0.90 inches; 22.86 mm).

As of January 31st, the mountain snowpack is in great shape. Most basins are near normal, with several reporting well above-normal snowpack. The only basins slightly below normal are the South Platte in Wyoming and Arkansas in Colorado. The several rounds of winter storms this month greatly improved the drought situation, with runoff likely to be in good shape this spring.

precipitation in inches (bottom) for January 2023. 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

Temperatures varied across the region, with areas ranging from 8 degrees F (4.4 degrees C) below normal to 6 degrees F (3.3 degrees C) above normal. Despite the wide fluctuation in temperature, no major locations ranked in the top 10.

Despite the overall lack of monthly records broken in the region, it was not a quiet month. Like December, January started with warmer temperatures while cooler temperatures dominated at the end. Temperatures reached 74 degrees F (23.3 degrees C) on the 2nd in Chaunte, Kansas. Not only were the temperatures well above normal, but they also lingered throughout the month. Ten days in Chanute were over 60 degrees F (15.6 degrees C) which tied for the second most in the month of January. The end of the month brought bitter temperatures throughout the region. Temperatures reached below –40 degrees F (-40 degrees C) in the mountainous parts of Colorado and Wyoming.

Drought Conditions

After back-to-back months of above-normal precipitation, drought conditions have started to finally improve. Some areas in the Dakotas and along the southern Front Range of the Rockies missed out on the much-needed precipitation, with conditions deteriorating as a result. Overall, there was a 3 percent decrease in D0 to D4 (abnormally dry to exceptional drought conditions).

Although North Dakota missed out on the precipitation this past month, drought conditions improved after the near-record snowfall in December. The state experienced a 12 percent reduction in D2 (severe drought) in response, however, nearly 80 percent of the state is still engulfed in D1 (moderate drought). Wyoming greatly benefited this month, with an 11 percent reduction in D0-D4 in the state. Elsewhere in the region, other improvements and degradation were observed. According to the Climate Prediction Center’s U.S. Monthly Drought Outlook for January, drought conditions will improve in southeastern Kansas.

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 and northeastern states. Increased chances of below-normal temperatures are present in the Dakotas and the northern portion of Wyoming.

Precipitation

The outlook for the next three months indicates below-normal precipitation across the southwestern parts of the United States and above-normal chances across the northwestern and midwestern portions. Above-normal precipitation is slightly favored in North Dakota and northwestern Wyoming. Drought-stricken Colorado, Kansas, and Nebraska all are slightly favored for below-normal precipitation.

Drought

The U.S Seasonal Drought Outlook released on January 31st indicates that improvements to drought conditions will continue in the Dakotas while deteriorating in southern Colorado.

December 2022 Climate Summary

December 2022 Climate Summary

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.

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.

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.

August 2022 Climate Summary

August 2022 Climate Summary

Dry Pasture in Western Kansas, Photo Courtesy of Kevin Rush

A Hot and Dry end to Summer

The summer of 2022 ended much like it began, with hot and dry conditions throughout the region. The resulting drought from these conditions and their effects has finally become clear, with numerous impacts on agriculture, livestock, and water resources. Kansas and Nebraska have taken the brunt of the drought, with conditions being as bad as 2012 in some places.

Agricultural conditions have steadily deteriorated over the summer in Kansas and Nebraska, particularly in the western parts of both states. According to the USDA National Agricultural Statistics Service, corn that was rated poor to very poor reached 50 percent in Kansas and 34 percent in Nebraska. This marked a 17 and 12 percent increase since the end of July. Fields across western Kansas are being cut for silage or filed for crop insurance as a result of the poor conditions. Even drought-resistant sorghum was impacted, with over 50 percent of fields in both states rated as poor to very poor. Nearly 78 percent of pastures in Nebraska and 65 percent in Kansas are rated poor to very poor. With such poor grasses, farmers have struggled to find feed for their cattle, and feedlots in western Kansas have been importing silage from over 50 miles away

Precipitation

Outside of the monsoon in the west, precipitation was spotty at best in August. The majority of Kansas and Nebraska were well below-normal this past month, further exacerbating the dire drought situation in both states.

The southwest monsoon brought beneficial precipitation to the western states, with locations such as Casper, Wyoming, and Alamosa, Colorado ranking in the top 5 wettest months on record. Sioux Falls, South Dakota, recorded their 8th wettest month with 6.88 inches (17.48 cm) of precipitation, with a large portion of this occurring during a record-breaking storm on the 7th. An incredible 5.44 inches (13.82 cm) of precipitation fell, setting a new daily precipitation record for August.

Nebraska was particularly dry, with numerous locations ranking in the top 10 driest. Omaha, Lincoln, Hastings, and Scottsbluff ranked in the top 10, with Grand Island and McCook placing 2nd driest. Not only was August dry for these locations, but also the entire summer. McCook observed their 2nd driest summer on record, with 3.37 inches (8.56 cm) of precipitation, which was slightly above the record of 3.31 inches (8.41 cm) set in 2012. Elsewhere in Nebraska, Norfolk and Scottsbluff recorded their 4th driest summers, with a dismal 1.98 inches (5.03 cm) of precipitation falling in Scottsbluff. Precipitation deficits continue to grow across the state, with areas over 10 inches below-normal since January 1st.

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 resulting 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

Temperatures were above normal throughout not only August, but the entire summer. Much of the region was 2 to 4 °F (1.1 and 2.2 °C) above normal in August. Overall, most of the region was 2 to 3 °F (1.1 and 1.7 °C) above normal this summer. Numerous locations across the region ranked in the top 10 warmest Augusts and summers.

Much above-normal temperatures were present in Wyoming and western Nebraska in August. Scottsbluff, Nebraska observed its warmest month on record, with an average temperature of 77 °F (25 °C). Nearby Chadron ranked second, as did both Cheyenne and Rawlins in Wyoming. Also in Wyoming, Sheridan Station Spotlight: Scottsbluff, Nebraska Above: Daily temperatures for August 2022, along with extremes and normals values in Scottsbluff, Nebraska. and Laramie ranked 3rd warmest on record.

The same area also recorded among the warmest summers on record. Cheyenne experienced its hottest summer on record, with an average temperature of 70.6 °F (21.4 °C). Scottsbluff ranked 2nd and Laramie ranked 3rd warmest. The oppressive heat this summer was not limited to just this area, however, with several locations in Colorado and Nebraska also observing their 3rd warmest summer on record.

This past summer had some extremely warm temperatures, which is reflected in the number of heat advisories issued by the National Weather Service. Kansas led the way, with 103 advisories issued throughout the state this summer

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

Drought Conditions

The southwest monsoon brought drought relief to Colorado and parts of Wyoming, while the rest of the region continued the trend of dryness and above-normal temperatures. Overall, there was a 7 percent increase in moderate to exceptional (D1-D4) drought in August. After several months of being drought-free, D1 was re-introduced in North Dakota.

After an entire summer of near-record heat and dry weather, extreme to exceptional (D3D4) conditions have become entrenched across southwestern Nebraska and western Kansas. This has taken a significant toll on agriculture, with poor crop conditions and impacts on livestock. In the eastern parts of both states, drought conditions were introduced and slowly began to spread. On the other hand, an above-normal amount of precipitation due to the southwest monsoon improved drought conditions in Colorado with D1-D4 reduced by 33 percent compared to the beginning of the month. According to the Climate Prediction Center’s U.S. Monthly Drought Outlook for September, drought development is likely across parts of Kansas, Nebraska, and the Dakotas.

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 high probability of Minor Flooding in northeastern South Dakota through November. According to the National Interagency Fire Center (NIFC), fire potential will be limited across the region through December.

The seasonal temperature and precipitation outlook presented below combine the effects of long-term trends, soil moisture, and when applicable, the El Niño Southern Oscillation (ENSO). To learn more about these outlooks, please visit http://www.cpc.ncep.noaa.gov.  

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 15th indicates drought conditions are expected to improve in southern Colorado and Kansas. Opposite of this, drought development is likely in parts of Nebraska, Colorado, and Kansas.

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 4th warmest month on record.

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.
