The National Weather Service says that rain will turn into snow Sunday evening and snow accumulation in some areas of northern Illinois is possible.
The National Weather Service (NWS) said Sunday that a “seasonably cold start” and “winter-ish weather” will kick off the week.
Sub-freezing temperatures in some areas Sunday evening and in most areas on Monday evening are expected.
The NWS said rain will transition to snow later Sunday afternoon into the evening.
McHenry and Winnebago counties, along with bordering areas, could see 1-3 inches of slushy snow accumulation, the NWS said.
Wind gusts up to 40 mph are also possible.
Motorists should allow for extra travel time Monday morning due to reduced visibility and wet roads.
Dry weather is expected Monday evening through Tuesday before unsettled weather returns midweek in the form of chances of showers and thunderstorms.
Last week, the NWS said the summer-like warmth on Thursday in the Chicagoland area broke records.
The highest recorded temperature was in Wheeling at 85 degrees.
At O’Hare Airport, the weather service recorded 83 degrees, which was a record high for April 13 in Chicago.
The old record was 82 degrees on that same date in 1887 and 1941.
