McHenry County is expected to see several inches of snow between Friday and Saturday evening.
A winter storm warning is now in effect from 9 p.m. Friday until 6 p.m. Saturday, according to the National Weather Service. Snowfall rates could reach 1 to 2 inches per hour Saturday morning. Snow covered roads and low visibilities will make travel hazardous from late this evening through Saturday evening.
While it’s too early to predict exact amounts, areas of McHenry County could see as much as 10 inches of snowfall by Saturday evening, National Weather Service meteorologist Casey Sullivan said.
“It’s in the range of possibility,” Sullivan said. “But that’s probably on the high side.”
And temperatures aren’t expected to climb much higher anytime soon, Sullivan added. After highs in the mid-20s Thursday, Friday’s highs are expected to stay in the mid-teens. On Saturday, temperatures will likely peak in the lower 20s, Sullivan said.
With periods of intense snowfall possible Saturday, Sullivan cautioned that driving could become hazardous.
“We could have a period Saturday where snow might fall fairly moderately for three, four or five hours,” he said. “If people don’t have to travel, wait until the roads are clear.”
The weather caused travel difficulties across the area Thursday, starting with high winds and drifting snow during the morning commute.
Falling snow and high winds Thursday afternoon caused whiteout conditions, further complicating travel.
Several accidents were reported, including a six-car crash on Route 14 in Woodstock, according to the McHenry County Sheriff’s Office.
Police were still dealing with reports of accidents Thursday night, the sheriff’s office said.
Winds gusting up to 40 mph were expected to cause additional problems overnight, according to the National Weather Service.
