Lake-Effect Snow Hits the Chicago Area as the National Weather Service Issues a Winter Weather Advisory, With Local Totals Possibly Over 3 Inches

Friday, November 13, 2026 · Weather · GSM News

The National Weather Service has extended a Winter Weather Advisory for the Chicago area until noon on Friday, November 13, warning of slippery roads during the Friday morning commute.

The advisory covers southern Cook County and eastern Will County in Illinois, along with Lake County, Indiana, including Gary, Hammond, Merrillville, Calumet City and Orland Park. A narrow band of lake-effect snow is forming near the southern end of Lake Michigan, and wet snow may continue to accumulate through Friday morning.

The National Weather Service office in Chicago forecasts that localized snowfall totals could exceed 3 inches, although temperatures near freezing may limit accumulation in some areas. Drivers are warned that visibility could drop sharply within the snow band and roads will be slick, and should allow extra travel time and slow down.

This is the Chicago area's first notable snowfall of the season, marking the start of winter weather patterns across the Great Lakes. As cold air continues to push south, temperatures in Chicago will fall further this weekend, and residents should dress warmly and watch for updated forecasts.
