Overview
|
A fast moving clipper system overspread the region on the morning of December 13th. In general, a widespread 2 to 5 inch event occurred along and south of the Highway 30 corridor. There were some very localized swaths of 6 inches or more from southwest of Iowa City to Wapello and Muscatine IA, and from far southeastern IA into portions of west central IL. The greatest impact was dangerous travel conditions on Interstate 80 in Iowa, where several multi-vehicle accidents resulted in the highway being closed much of the afternoon and evening. In addition, temperatures dropped sharply behind the departing system, with sub-zero air temperatures and wind chills in the -20 to -30 degree F range for several hours Sunday morning Dec 14th.
