Overview

Scattered thunderstorms with rain, freezing rain, and sleet was seen across the area during the morning of Wednesday, April 18th; especially north and west of a line from Ottumwa to Dubuque. This resulted in slick roads and hazardous travel. Towards midday, the mixed precipitation had changed to snow north of Interstate 80. Snowfall accumulations of 1 to 3 inches were seen along and north of Highway 20.  Higher amounts between 5 to 12 inches fell along the northern two tiers of counties in Iowa. Meanwhile, areas south of I-80 only saw rain from this storm system. Temperatures were only in the 30s to lower 40s; which is about 25-30 degrees below normal for late April.
