Pacific moisture and warm air wrapped around a large upper level low pressure system that moved from the northern Rockies slowly southeast into the eastern Dakotas from Saturday January 8 into the morning of January 11th.  This brought a 36 to 48 hour period of snow to eastern Nebraska and southwest Iowa.  Although the snow was mostly light, periods of moderate snow were observed.  In addition, since the snow fell for an extended time, total amounts over most of eastern Nebraska and southwest Iowa reached 7 to 10+ inches.  Most of the heavier amounts, centered on a 24 hour period from the morning of the 9th through the morning of the 10th, were in northeast Nebraska.  Winds during much of the event were 10 to 20 mph which limited blowing and drifting.  However, winds did pick up during the afternoon and evening of 1/10 into the early morning hours of 1/11.  This caused drifting snow across most of the region with some reduced visibilities in blowing snow as well.  Heavier storm total snowfall amounts included...12 inches in Columbus and Oakdale, Nebraska, 11 inches near Verdel, Loretto, and Bloomfield, Nebraska and Little Sioux, Iowa and 10 inches at Norfolk, Wayne, Ft. Calhoun, Gretna, David City, Lyons, Neligh, and Weston, Nebraska and Castana, Iowa.
