Northeastern Illinois and Chicago possibly could get hit with another snowy, rainy weekend.
As of Monday, the National Weather Service was forecasting light rain and light snow beginning Friday morning in McHenry County.
The NWS does not yet have the final forecast, which is in the preliminary stages, meteorologist Charles Mott said Monday. While Mott said Sunday that another storm like Friday’s and Saturday’s is likely for this weekend, it is too early to say for sure, he said Monday.
With an 80% chance of precipitation Friday, the NWS forecasts snow before 1 p.m., then rain and snow between 1 and 3 p.m. That could be followed by rain after 3 p.m. Snow then could return before 7 p.m., and rain could continue until 3 a.m. Saturday. Rain and snow are likely after 3 a.m.
“Friday after morning rush, we could see some accumulation. Totals right now, who knows? It could get worse,” said Andy Rose, maintenance supervisor for the McHenry County Division of Transportation.
Saturday’s forecast calls for mostly cloudy conditions with a 40% chance of snow and highs in the mid-30s. Temperatures Saturday night and Sunday are forecasted to drop significantly with lows between 4 to 8 degrees and highs between 17 to 21 degrees, Mott said.
Sunday will be partly sunny with a high near 20. Saturday and Sunday could become windy, Rose said.
“If we get 2 inches Friday, we’re going to be battling the wind Saturday and Sunday with blowing snow,” he said.
After icy roads caused problems over the weekend, MCDOT workers will be watching the forecast “very closely” this week, Rose said. McHenry County Sheriff’s Deputy Sandra Rogers said they responded to 23 crashes scattered across the county during the storm.
“Weather is our most important thing we do around here,” Rose said.
MCDOT staff are preparing their trucks and planning shifts for the forecasted winter weather this weekend.
“We’re getting ready. We want to make sure our equipment is ready to go every morning,” Rose said.
During the past weekend, Algonquin saw 2.5 inches of snow while Woodstock accumulated at least an inch.
