The first snowflakes of the season fell Monday morning in northeast Illinois and the National Weather Service says a “burst of snow” is expected later this afternoon.
The National Weather Service (NWS) issued a hazardous weather outlook for Lake and McHenry counties, including portions of North Central Illinois, Northeast Illinois and Northwest Indiana.
The NWS said a strong fall storm system will bring windy conditions to the area Monday into the evening.
Wind gusts of up to 35 mph are possible and sub-freezing temperatures are expected tonight.
The NWS said an “upper-level disturbance” will interact with the unseasonably cold air mass in place and result in a burst of some snow later Monday.
Little or no accumulation is expected but snow could fall at a “pretty good clip” across the Chicago metro area south down the Interstate 57 corridor.
The timing is 3 p.m. to 9 p.m., according to the NWS.
Forecasters said people should prepare for extra travel time and check road conditions before driving.
In Northwest Indiana, lake enhancement is expected to result in a period of heavy, wet and wind-driven snow.
