Event Review: Easter Snowstorm of April 1, 2018

Fast Facts:

Snowfall of 4 to 6 inches fell across a narrow corridor of central Illinois on Easter Sunday, April 1. Some local totals of 6 to 8 inches were reported west of Lincoln to near the Mississippi River.
The most snow ever to fall on Easter was on April 4, 1920, when 6 to 10 inches fell in an area from near Quincy northeast to southern Lake Michigan.
Clearing skies and the fresh snow cover resulted in rare April single digit and sub-zero temperatures in a few areas on Monday morning, April 2.
