KIMBALL, Neb. – The first significant regional snowfall of the season came with the arrival of a mild winter storm Sunday evening. As the weather front moved in during the afternoon, temperatures tumbled from the mid-60’s to mid-40’s and a northwest wind kicked up. Scattered drizzle and light rain began to fall at about 10:30 p.m., and as temperatures continued to fall, the rain transitioned to snow just after midnight. Light to moderately heavy snowfall persisted throughout the night and up until about 11 a.m. when warming air caused the snowfall to transition back to light rain.
By the time precipitation abated and the skies began to clear about four inches of wet snow had fallen, and that snow contained about 0.75 inches of liquid precipitation.
As the weather front passed and evening fell on Monday, the temperature began to drop sharply as warmth radiated away under cloudless night skies. Overnight temperatures plunged to 23 degrees, heralding the first hard freeze of the season.
Sugarbeet harvest was in full swing over the last week and harvesters doubled their efforts to get the crop out of the field before the wintry storm arrived. On Saturday and Sunday from dawn to dusk a non-stop stream of beet trucks made their way to the sugarbeet receiving station north of Kimball.
Although good progress was made, the storm arrived before many producers could finish harvest. Rain and wet snow falling on unfrozen ground made for muddy fields, bringing harvest activities to a halt, leaving producers hopeful that a promised spell of warm, dry weather will allow for timely completion of the 2017 sugarbeet harvest.
Summer crops continued to mature over the last week with corn and sunflowers drying down nicely. Proso millet has been mostly harvested, as has much of the late-season hay crop.
The wet snow was beneficial to recently seeded winter wheat, but Monday night’s hard freeze may have been hard on newly-germinated stands. Pastures and rangeland also benefitted from the rain and wet snow.

U.S. Drought Monitor
The High Plains: Beneficial rains (generally 2-5 inches) in the past 14-days have resulted in drought depiction improvements across North Dakota and eastern South Dakota this week. Accordingly, the impacts line was adjusted to better reflect the updated conditions across this area. In North Dakota, rainfall and cold temperatures halted agricultural progress where rainfall was significant. Short-term precipitation has been helpful, but needs to be weighed against long-term drought impacts.
West: In southeastern Arizona, the D0 “hole” in the depiction was filled in with D0, as there is little difference in conditions between that area and its surroundings. In Colorado, D0 was removed from the Denver area, and some D0 was trimmed away from Lake, Chaffee, and eastern Gunnison Counties. These locations received ample precipitation in September, and SPIs are mostly positive across multiple timescales. In eastern Utah (Uintah County), the western part of the moderate drought area (D1) was trimmed away. This area ended the Water Year with near average precipitation, and received above average precipitation in September. In Montana, welcome precipitation and increasing soil moisture warranted significant improvements statewide this week.
National Summary: A cold front approached the Eastern Seaboard early in the drought week, which drove Tropical Storm Maria farther away from the mid-Atlantic coast, keeping substantial impacts to a minimum. About the same time, the western edge of this cold front moved through southern Texas and New Mexico, bringing significant upslope precipitation (0.5-3.0 inches, locally greater) to the southern Great Plains and adjacent Rockies. Another cold front then moved southeastward out of central Canada, accompanied by primarily light precipitation (0.75-inch or less) to the Great Lakes region and Northeast. Towards the end of the drought week, yet another cold front progressed eastward across the Rockies, and the northern halves of the Great Plains and Mississippi Valley, bringing 1-2 inches of rain to much of the region.
