Winter Storm To Hit Chicago Area Sunday Into Monday: NWS

ILLINOIS — The National Weather Service is predicting a winter storm will hit the Chicago area into early next week, but the system's exact track was still unclear on Friday.

Snow is expected Sunday into Monday, with the highest amounts of accumulation expected south of Interstate 80, across central Illinois and Indiana.

"A winter storm will bring accumulating snow and travel impacts to the region early next week," the NWS wrote Friday morning on X. "We will continue to refine the forecast track as it approaches, including the placement of the northern edge of the snow and any additional lake effect potential."

In addition to the track of the system, weather forecasters also don't yet know whether lake effect snow will lead to impacts in northeastern Illinois and northwest Indiana on Monday.

Temperatures leading up to the storm continue to chill. Friday will see "blustery and cold" but sunny weather with a high between 21 and 25 degrees before it dips to between 19 and 22 degrees on Saturday. Sunday's high is forecast between 21 and 28 degrees, and it's expected to warm slightly on Monday for a high of around 25 to 30 degrees.
