Heavy Snow Forecast Prompts Winter Storm Warning for Chicago Area
A significant winter storm is poised to impact the Chicago area and Northwest Indiana, prompting a Winter Storm Warning. The warning is set to commence on Sunday evening and continue into Monday afternoon. Forecasters predict that this storm could deliver over a foot of lake-effect snow in some locations, making travel particularly perilous during the Monday morning commute.
Winter Storm Warning Details
The Winter Storm Warning will commence at 9 p.m. on Sunday. It will remain in effect until noon on Monday for:
- Cook County, Illinois
- Eastern Will County, Illinois
- Kankakee County, Illinois (starting at midnight Monday)
- Lake and Porter counties, Indiana (until 6 p.m. Monday)
- LaPorte County, Indiana (already in effect until midnight Tuesday)
- Lake County, Illinois (from 9 p.m. Sunday to 6 a.m. Monday)
Additionally, a Winter Weather Advisory will be active for DuPage and western Will counties in Illinois, as well as Newton and Jasper counties in Indiana.
Forecast and Conditions
Intense bands of lake-effect snow are expected to develop after 9 p.m. on Sunday. These conditions may lead to near whiteout situations, especially overnight and into Monday morning. Northwest winds could reach speeds of 35 mph, amplifying the hazardous travel conditions.
Snowfall rates could reach up to 3 inches per hour. Overall snow accumulation is predicted to be between 8 and 12 inches in most areas. However, in regions where snow bands stall, totals may be significantly higher—potentially reaching between 12 and 18 inches, particularly near the shores of Lake Michigan.
Travel Advisory
Travel near the lake is expected to be extremely challenging. Residents are strongly encouraged to stay indoors if possible. For those who must travel, using public transportation is recommended to avoid hazardous road conditions.
