Winter Weather: Snow, 'Very Hazardous Travel,' Crashes In IL

ILLINOIS — A winter weather advisory is in effect until 10 a.m. Wednesday for most of the Chicago area, including central, northern and southern Cook County; DuPage County; southern and eastern Will County; and Grundy, Kane, Kendall, Lake and McHenry counties.

The National Weather Service advised drivers to watch out for snow and slippery conditions on elevated surfaces, such as bridges, overpasses and ramps.

"Multiple significant accidents have occurred on area roadways," the weather service said early Wednesday, adding that conditions created "very hazardous travel." Illinois State Police were asking drivers to avoid travel Wednesday morning.

Snow is expected to diminish as temperatures rise by mid-afternoon.

Accumulating snow should end over most of the Chicago metro area by 9 a.m., but continue until 10 or 11 a.m. across the far southern suburbs and northwest Indiana, the National Weather Service said.

Meanwhile, more winter weather is expected in Illinois later this week, with a "winter-like pattern into Friday morning" and two rounds of snow before spring-like weather returns, according to WGN's Tom Skilling.
