Strong Winds and Some Snow Occurred December 10th and 11th, 2010

Strong northwest winds gusted over 50 mph across much of western and north central Nebraska Friday evening through Saturday. The intense winds were the result of a significant pressure gradient between low pressure that produced a blizzard in the Midwest and a high pressure system in the Northern Plains. The highest wind gust measured in the local area was 57 mph at Big Springs, which occurred at 7:42 p.m. MST Friday evening.

One to four inches of snow did fall over north central Nebraska as an extension of the storm in the Midwest. Significant blowing and drifting snow and blizzard-like conditions occurred across parts of Boyd, Brown, Holt, and Keya Paha Counties.
