Regional Significant Events for December 2024 – February 2025
Highlights for the Basin
The northern plains experienced several large temperature swings this winter.
The coldest temperatures, -45°F, were observed in portions of Montana and
western North Dakota. While further south, temperatures dropped below -20°F in Kansas in mid-February. Combined with gusty conditions, wind chills were as low as –68°F in Bowbells, North Dakota. Just a few days later temperatures soared into the 70s, with some stations reporting 100-plus degree F changes.
Outside of the Rocky Mountains and eastern Kansas, snowfall was well below
normal this winter. Parts of the Dakotas and Nebraska were 25 inches below their normal snowfall at the end of February. After a dry fall, conditions were optimal for fires with dozens igniting in South Dakota and central Nebraska.
Regional Climate Overview for December 2024 – February 2025
Temperature and Precipitation Anomalies
Despite a warm start, temperatures this winter were mostly below normal.
December was the 4th warmest on record for the Missouri Basin states, with
dozens of counties experiencing their warmest on record. Outbreaks of arctic
air in the middle of January and February led to below normal temperatures in
both months.
This winter was dry, with snowfall well below normal across much of the
northern and central plains. Precipitation in December was virtually nonexistent in KS and NE, with 18 counties ranking driest. January brought some moisture to eastern KS and the western portions of the basin but was still well below normal across the eastern parts of the Dakotas and Nebraska. Precipitation was spotty in February outside of MT and northwestern WY.

Changes in Drought Conditions
Compared to last year, drought conditions are significantly worse.
Only 25 percent of the basin was in drought at the end of February last
year, while 65 percent is this year. Portions of Nebraska, the Dakotas,
and Wyoming experienced up to four classes of degradation, with drought
firmly entrenched after the dryness this winter.

Regional Impacts for December 2024 – February 2025
Agriculture
Below normal snowfall has soils and crops in poor shape within the
basin. Winter wheat is struggling in Nebraska and South Dakota, with over
35 percent rated as poor to very poor in both states. Frost depths in North
Dakota reached 70 inches due to minimal snow cover, while ponds and
dugouts are dry from the overall lack of moisture dating back to the fall.
Water Resources
Snowpack in the mountains is in good shape, particularly in the Northern
Rockies. However, runoff is projected to be 86 percent of normal, with
lower spring and summer releases expected. The temperature swings led
to ice jams on the Missouri River, with some minor power shutdowns due
to lower flows downstream from the jams.
Transportation
Near record snows across eastern Kansas and western Missouri in January wreaked havoc on transportation. The Kansas City metro spent over half their annual snow removal budget on the blizzard in January, with three fatalities from car crashes in the state of Kansas. To the north, the snowstorm in February led to two deaths and hundreds of wrecks in Nebraska.
Regional Outlook for April – June 2025
According to NOAA’s Climate Prediction Center, the outlook for the
upcoming season indicates increased chances of above-normal
temperatures across the southern portions of the Basin. Increased chances
of below-normal precipitation are present in Kansas, Nebraska, Wyoming,
and parts of Montana and South Dakota. The rest of the Basin has equal
chances of above, below, and near-normal precipitation.
La Niña influences will end this spring, and ENSO-neutral conditions will
likely be present through the summer. After a dry fall and winter, above
normal temperatures and below normal precipitation this spring would be
detrimental to rangeland production and soil moisture.
