A winter weather advisory has been issued for McHenry County ahead of the potential for several inches of snow on Friday, forecasters said.
The National Weather Service (NWS) issued a winter weather advisory early Thursday morning.
The advisory will go into effect at 1 a.m. Friday and expire at 4 p.m. Friday.
The advisory covers McHenry, Winnebago and Boone counties.
The NWS said wet snow is expected with total snow accumulations of one to four inches.
The highest snowfall is expected near the Illinois-Wisconsin state line and the lowest across southern portions of the counties.
Motorists are reminded to plan for slippery road conditions by slowing down and using caution while traveling, the advisory said.
The hazardous conditions could significantly impact travel overnight into the Friday morning commute.
A heavy snow band is expected just north of the Illinois-Wisconsin state line, the advisory said.
If the band shifts south, “more significant impacts” would be expected in the three Illinois counties under the advisory.
A hazardous weather outlook was also issued for Lake County for slushy snow accumulations likely resulting in travel impacts.
