Several inches of snow fell mainly along and north of Interstate 80 on this Wednesday night. A band of snow formed along the Wyoming-Colorado border Wednesday afternoon, and it gradually expanded eastward into western and southwest Nebraska. The band continued to expand to the east and intensify during the evening. By 10 PM CST, a mature band of snow, about two counties wide, extended across south central Nebraska, from west-northwest to east-southeast, primarily along and north of Interstate 80. In the core of this band, moderate snow was falling. This band gradually moved northeast through the night, and by 6 AM CST, the snow had ended across south central Nebraska. The highest snowfall amounts included 8.0 inches at Elba and Greeley, 7.5 near Ord, 7.0 at Arcadia, Belgrade, Genoa, Loup City, and Osceola. Seven inches also fell near Scotia and Palmer, with 6.9 at Stromsburg, and 6.0 at St. Paul.
Thursday morning, the westbound lanes of Interstate 80 were closed near the Giltner exit (mile marker 323) due to an accident involving four semi trucks. Two of the trucks collided while the other two drove into the ditch, one of which jackknifed. There were no injuries. Another crash occurred east of Grand Island near mile marker 320, but no details were available.
An Arctic air mass covered the Plains. The Arctic front was stationary against the Rockies from Montana through Wyoming and Colorado, with several small and weak low pressure centers along it. The surface flow had become cyclonic over Nebraska as a weak 1008 mb low formed over southeast Colorado into moved into southwest Kansas Wednesday night. In the mid- and upper-levels, the flow was relatively zonal over the United States, with troughs over the Northwest and Northeast. A low-amplitude shortwave trough (best seen at 700 mb) moved out of Colorado and New Mexico into Nebraska and Kansas. This snow band occurred coincident with strong warm air advection and mid-level frontogenesis and weak instability.
