A major winter storm moving through Illinois and much of the Midwest impacted parts of northeastern Illinois Monday morning, with snow and freezing drizzle expected to continue for some as the day progresses. said the NBC 5 Storm team.

But not all areas will experience the storm’s effects, NBC 5 meteorologist Alicia Roman said.

“Snow doesn’t affect everyone,” Roman said Monday morning. “Most of you will remain dry or clear, but some will see a lake-effect plume of snow.”

According to the National Weather Service, a winter weather advisory was in effect for Lake, Cook and DuPage counties until 4 p.m. Monday. In these areas, lake effect snow is expected to continue during the morning and evening commute.

By Monday evening, snow is expected to reach Lake and Porter counties in Indiana, Roman said.

Snow timeline, road conditions

Counties in far northeastern Illinois were hardest hit by the storm early Monday morning, with more snow falling in Lake County and Kenosha County in Wisconsin, Roman said. Other areas also experienced areas of freezing drizzle, leading to icy roads.

According to Roman, the lake effect snow plume could sometimes intensify late in the morning.

“During lake effect, weather can vary from bands of locally heavy snow to dry weather just a few miles away,” the NWS warned. “Visibilities can also vary significantly. Be prepared for rapid changes in weather, visibility and road conditions.”

According to NBC 5 Traffic reporter Kye Martin, some parts were already experiencing skids and crashes due to winter conditions, including in the departure lanes of I-290 in Austin, in the northbound and southbound lanes of I- 294 in Golf, and on western suburban roads.
