KIMBALL, Neb. – A fast-moving weather front delivered a blast of arctic air to the tri-state region Monday, but air temperatures were already warming back up late on
The front arrived in the wake of a nicely warm Nov. and during the appearance of a “super” full moon.
Early Monday morning the wind kicked up as the front arrived and it was soon driving a fine, cold snow. Snowfall was reportedly heavier in the north Panhandle, causing wintry driving conditions. Across the south Panhandle snowfall totals were less, but the cold wind was nonetheless miserable.
During the day Monday temperatures climbed only into the low 20’s, and Monday night’s lows fell into the single digits and low teens.
By Tuesday the sharp cold had passed and the sun was shining, although the breeziness continued.

U.S. Drought Monitor
Northern Plains: This week conditions deteriorated in central and eastern Kansas as well as in western North Dakota. In North Dakota, areas of Moderate Drought (D1) and Severe Drought (D2) expanded in response to below normal precipitation during the past 30-to-60 days as well as reports of signs of negative impacts to the winter wheat crop.
According to the USDA World Agricultural Outlook Board, winter wheat conditions are currently rated as 38 percent poor to very poor for South Dakota. In Kansas, scattered below normal stream flows and below normal precipitation during the past 30 days led to expansion of areas of Moderate Drought (D1) in south-central.
During the past week, the region was dry and temperatures were well above average especially in western portions of the Dakotas where temperatures were 15-to-18 degrees
West: During the past week, the warm and dry pattern continued across the Southwest, southern Rockies, and eastern portions of the Intermountain West while northern California, western Oregon and Washington, and the northern Rockies were impacted by several storms that delivered locally heavy rainfall and mountain snow to the higher elevations.
According to the Natural Resources Conservation Service SNOTEL network, snowpack conditions are above normal in the following areas: Cascades (Washington), Sawtooth Range (Idaho), northern Rockies (Montana/Wyoming), and portions of the central Sierra (California). Conversely, snowpack conditions were well below normal in the mountain ranges of the Arizona, western Colorado, eastern Nevada, New Mexico, and Oregon.
On the map, areas of Moderate Drought (D1) expanded in central and northern Arizona, western Colorado, western New Mexico, and across Utah in response to short-term precipitation deficits (30-60 days), poor snowpack conditions, and anomalously warm temperatures. According to the USDA, California’s topsoil moisture is currently rated as 75% short to very short.
During the past week, average temperatures were well above normal (5-to-18 degrees) across the region with numerous daily high temperature records broken from California to Colorado.
National Summary: This week saw a series of storms impact the Pacific Northwest, northern California, and northern Rockies. The heaviest precipitation was observed across the Olympic Mountains and North Cascades of western Washington where precipitation accumulations (liquid) ranged from 4-to-12 inches. In the Puget Lowlands of western Washington, runoff from the storm event led to severe flooding on the Skagit River that peaked at 5 feet above flood stage on Friday.
Elsewhere in the West, unseasonably warm temperatures were observed across parts of the region including record-breaking high temperatures reported across southern California, the Desert Southwest, western Great Basin, and along the Front Range of Colorado. In the Southwest, the warm and dry pattern of the past several months led to expansion of areas of moderate drought in Arizona, New Mexico, and Utah while drought-related conditions improved in western Montana.
In the High Plains, conditions were very dry this week, and temperatures were well above normal across the entire region.
In the South and Southern Plains, the overall dry pattern during the past 30-to-60 days led to expansion of areas of moderate-to-severe drought across portions of Arkansas, Louisiana, Mississippi, eastern Oklahoma, and eastern Texas.
In the Mid-Atlantic states, short-term precipitation deficits during the past 30 days led to deterioration of conditions across portions of North Carolina and Virginia.

U.S. Conditions and Weather Report
For the second week in a row, “open” weather across most of the country favored final harvest efforts and other late-season fieldwork.
Significant precipitation was limited to the Northwest, although rain and high elevation snow briefly spread as far south as northern and central California.
Nearly all other areas, including the Plains, Midwest, Southwest, and East, received little or no precipitation.
Declining soil moisture reserves cross a vast area stretching from the Southwest into the middle and lower Mississippi Valley, as well as portions of the Atlantic Coast States, led to increased stress on some winter grains and cover crops. Some of the driest areas, including the mid-South, were also experiencing significant stress on pastures and reduced surface water supplies.
Warmth covered much of the country, with near-normal temperatures limited to the Northeastern and Mid-Atlantic States and areas along the Pacific Coast. Weekly temperatures averaged at least 10 degrees above normal across large sections of the Plains, Southwest, and upper Midwest.
In the South and East, mild weather replaced previously cool conditions.
