Slippery road conditions are in Wednesday’s forecast for McHenry County residents, according to the National Weather Service.
Wintry precipitation is expected to stretch throughout the day Wednesday, bringing with it the ingredients for a messy morning commute.
The forecast also caused Harvard School District 50 to delay start times Wednesday. Buses will arrive at the bus stop two hours later than usual, district officials announced Tuesday night.
The service issued a winter weather advisory Tuesday morning warning that freezing rain, snow accumulations up to 2 inches and ice up to one-tenth of an inch could cause travel difficulties.
The advisory will be in effect until
3 p.m. Wednesday, according to the service.
McHenry County drivers likely will encounter snow at the start of the morning. As the morning progresses, snow likely will transition to a freezing drizzle or freezing rain, according to the service. The freezing drizzle is likely to fall between noon and 2 p.m. Wednesday.
Warmer air is expected to shift from the south, transitioning some of that freezing rain to “just plain rain,” according to the agency. The temperature will reach a high of 34 degrees with an east wind between 10 and 20 mph that should become southwest in the afternoon.
Heading into Wednesday night, there is a slight chance of drizzle before 10 p.m., with a slight chance of freezing drizzle between 10 p.m. and midnight.
The temperature is expected to reach a low of 20 degrees.
By Thursday, McHenry County residents could see some relief with a forecast that’s mostly sunny with a high temperature near 31 degrees.
