Overview

A compact strong upper wave moved east from northeast Nebraska into northern Iowa the night of April 17-18, bringing rain, sleet and snow across the area. As the system approached the region, rain and a mix of precipitation started to fall along the Missouri River into northwest Iowa shortly after midnight. Rain quickly changed to moderate snow (heavy at times) along and west of the I-29 corridor, while northwest Iowa were reporting thunder sleet and thunder snow early in the morning hours. Precipitation quickly changed to widespread snow after 4 am Wednesday, with snowfall rates of 1 to 2 inches per hour. Snowfall amounts range from 2 to 10 inches. Highest snow accumulations occurred from the Interstate 90 corridor and southward.
