McHenry County plows are clearing and salting the roadways Wednesday morning as the snow tapers off and frigid temperatures and gusty winds set in.
A winter weather advisory is in effect until 10 a.m., according to the National Weather Service in Chicago. A wind child advisory is also in effect until 5 a.m. Thursday.
Between 2 and 4 inches of snow is expected for most of the greater Chicago metropolitan area, including southern McHenry County. Between an inch or two of snow is forecasted for northern McHenry County.
The heaviest report of snowfall as of 7 a.m. was in Yorkville, where 1.8 inches has fallen thus far, according to the weather service.
Locally, plows began working at around 3 a.m.
"I think the roads are in good shape overall," said Mark DeVries, maintenance superintendent for the McHenry County Division of Transportation. "The issue for us will be the winds blowing snow in some areas if they pick up this afternoon. We want to get everything off the roadways before it gets really cold."
Area dispatchers were reporting some accidents caused by slick road conditions.
The forecast for McHenry County predicts temperatures around 16 degrees Wednesday, with a sharp drop to -5 this afternoon into the evening, with wind chills as low as minus-21 degrees.
