A strong upper level storm system sent moisture streaming northward into the Central Plains Monday December 10th into the early morning hours of Tuesday December 11th. The primary weather problems south of I-80 were centered on significant ice accumulations, while snow was the predominated precipitation type north of I-80.
Cold sub-freezing air near the surface was in place all across the region while a nose of warm air a few thousand feet above the surface resulted in rain that quickly froze upon contact with the surface. Hence the stage was set for a significant ice storm across northern Kansas and portions of south central Nebraska. Widespread freezing rain resulted in ice accumulations of .25 to .50 inches along and south of I-80. With most of the precipitation falling as freezing rain and sleet there was very little in the way of snow south of I-80 with only trace amounts in Kansas. Nebraska locations south of I-80 had snow and sleet totals ranging from a trace up to around 3 inches.
The warmer air aloft lasted only briefly north of I-80 before colder air moved in quickly changing freezing rain to snow. Consequently, ice accumulations decreased rapidly from around .25 inches along I-80 to predominately trace amounts north of I-80. However, the quicker change over to snow did allow for more substantial snowfall amounts north of I-80 with most locations seeing 2 to 6 inches of snow.
