Winter Storm Warning issued for NE Illinois including Chicago as heavy snow expected Monday

Weather Blog

CHICAGO — A Winter Storm Warning issued for most of the Chicago area will take effect Monday afternoon and last through Tuesday as heavy snowstorms could bring as much as 8″ of snow to some areas.

According to the National Weather Service, a winter storm moving into the area Monday afternoon will bring wet, heavy snow that may be mixed with freezing rain or sleet at times, along with winds of up to 40 mph.

The heaviest snowfall is expected late Monday afternoon through Monday evening, likely making for difficult driving conditions during the evening commute. Some power outages are even possible as the wet, heavy snow may mix with sleet and weigh down trees and telephone poles.

Winds will start moderately strong Monday morning and strengthen with the storm’s approach Monday afternoon peaking Monday night into Tuesday, causing pounding waves to hit the lakefront and waves of 8′ to 12′.

While it’s not enough to call it a “blizzard,” modeling of the incoming system continues to coalesce around the notion that Chicago is headed for its largest winter snowfall of the season after the storm moves in Monday around 4 p.m., give or take an hour. Most models suggest 8″ of snowfall on average, although they range from 4″ to as much as 12″.

Snowfall forecast for 6pm Monday

A longer duration of light to moderate snowfall will continue late Monday into Tuesday morning, possibly impacting the Tuesday morning commute on as well. As much as 5-8″ of snow is expected in some areas. The storm is expected to cause difficult driving conditions and power outages are possible.

A Winter Storm Warning will be in effect in Grundy, Kane, Kendall, La Salle counties from 1 p.m. Monday to noon Tuesday, and in Cook, DuPage, Lake, McHenry and Will counties from 4 p.m. Monday- 5 p.m. Tuesday.

A Winter Storm Watch will also be in effect from Monday 12 pm to Tuesday at noon for DeKalb, La Salle, Kane, Grundy and Kendall counties.
