URGENT - WINTER WEATHER MESSAGE

1049 AM CDT Mon Mar 15 2021

...Late Season Winter Storm Continues...

.A late winter storm system will continue to impact Iowa and 
northwest Illinois through this afternoon. A wintry mix will 
changeover mainly snow, but there may be additional periods of a
wintry mix of freezing rain, sleet and snow at times into the
afternoon. Most sleet and snow accumulations will occur along and
north of Interstate 80, with moderate to heavy wet snow north of 
highway 30. The rounds of freezing rain will result in a light 
glaze, especially on elevated surfaces. Strong east winds gusting
up to 40 MPH will also add to the hazard by combining with the
falling snow to sharply reduce visibility down to a half mile or 
less at times, especially in open areas.
