Lake-effect Snow and Whiteout Conditions in the Great Lakes Region; Below-average Temperatures in the East

Heavy lake-effect and lake-enhanced snow will persist downwind of the Great Lakes and produce some whiteout conditions that could cause difficult travel conditions. A coastal low will produce moderate to heavy snow over parts of southern and eastern New England into the afternoon. Below average temperatures are expected across the eastern U.S., particularly with chilly morning temperatures. Read More >

Overview

A winter storm spread light to moderate snow across much of eastern Iowa, northwest Illinois, and northeast Missouri. The snow began Wednesday (Feb 12) afternoon and ended early Thursday (Feb 13) morning   Snowfall amounts ranged from around 1 inch along a line from Manchester IA to Cedar Rapids IA to Sigourney IA, to near 4 inches in west central Illinois. A snow total of 5 inches was measured at the Augusta IL (Hancock Co IL) NWS COOP station.

In addition to the snow, strong winds gusts up to 40 mph were seen Wednesday night and early Thursday as an arctic cold front pushed through the area.  This caused some blowing and drifting of snow, leading to hazardous travel conditions and a few accidents for the Thursday morning commute.
