Ice Storm and Heavy Rain Overview

A well advertised storm system brough a mix of precipitation across all of eastern Iowa, northwest Illinois and northeast Missouri Wednesday, February 22nd. Precipitation began as rain during the early morning, but quickly changes to a mix of sleet and freezing rain as it progressed north over areas along and north of Interstate 80. This precipitation continued throughout the day before tapering off during the mid to late evening hours.

Given the amount of moisture associated with this system, rain and ice amounts were high. Rainfall totals of around 1.00 - 1.50" were observed along and east of the Mississippi River. Ice amounts of a few hundredths up to three tenths of an inch were observed, with the later mainly along and north of the Highway 30 corridor. This ice lead to slippery travel conditions and power outages.
