Icy conditions possible during rush hour

CRYSTAL LAKE – Evening commuters could encounter icy conditions during rush hour as temperatures drop below freezing, according to the National Weather Service.

With roughly a half-inch of snow falling in some areas of McHenry County, meteorologist Mike Bardou said residual moisture could freeze on roadways. Accumulation has only occurred in grassy areas, he said.

Visibility, which Bardou said declined to a half-mile during the peak snowfall in the early afternoon, is not expected to be limited as the snow should slow to a stop by 5 p.m. in areas north of Chicago and 7 p.m. in areas south of the city.

Temperatures could drop to 20 degrees overnight, according to the National Weather Service.

Bardou said the next chance for snow could come Thursday night with a mix of rain as temperatures hover around 32 degrees. Weather will then warm over the weekend, reaching the 50s.
