Winter Weather in South Sioux, Nebraska

An official NWS Cooperative Observer located 3 miles E of Agate measured 5 inches of snow.

A weak cold front brought widespread light to moderate snowfall to portions of the western Nebraska Panhandle on the 11th, resulting in localized snowfall totals of 3 to 6 inches with the highest accumulations generally occurring near terrain features such as the Cheyenne and Pine Ridges. In the wake of the intense arctic cold front that followed, temperatures plunged to between -15 F and -30 F across much of western Nebraska, with localized areas of temperatures approaching -40 F. This combined with elevated wind speeds resulted in a prolonged period of wind chills of -35 F to -55 F across all of western Nebraska from the evening of 1/12 through the morning of 1/16. Daytime high temperatures ranged from -5 F to -15 F for many locations on 1/13, with Chadron and Alliance setting all time records for the coldest high temperature in the month of January.
