A prolonged lake effect snow event is expected to impact northwest Indiana and northeast Illinois from Friday morning through Saturday afternoon, with hazardous travel conditions possible near Lake Michigan.
According to the U.S. National Weather Service, Arctic air moving across Lake Michigan will support persistent lake effect snow bands, primarily affecting Lake and Porter counties in Indiana, with additional impacts possible into northeast Illinois, including areas near Chicago. The highest confidence for snowfall and travel disruption remains closest to the lakeshore.
Forecasters indicate a potential for 2 inches or more of snow, with localized snowfall rates briefly exceeding 1 inch per hour within stronger snow bands. Most accumulation is expected to fall during short, intense bursts, making conditions highly variable over small distances. Areas just a few miles inland may see little accumulation, while locations near I-94, I-80, US-12, and US-30 could experience rapidly deteriorating road conditions.
The most impactful window for lake effect snow appears to be Friday morning and afternoon, with additional bands possible Friday evening into Saturday morning. Snow intensity is expected to gradually diminish later Saturday, though lingering bands could persist into the afternoon.
Cold conditions will continue through the event, with highs in the teens to low 20s and wind chills frequently below zero, especially during the early morning hours. These temperatures may worsen travel impacts by allowing snow to accumulate quickly on untreated roads.
Officials warn drivers to be prepared for sharply reduced visibility, snow-covered pavement, and sudden whiteout conditions. Motorists are urged to slow down, allow extra stopping distance, and carry winter safety supplies when traveling.
Residents are encouraged to stay tuned to updated forecasts, as lake effect snow bands can shift east or west with little notice. Conditions are expected to gradually trend milder late this weekend into early next week, though another snow chance may develop Sunday night.
This weather pattern may be especially disruptive for morning commuters and weekend travelers along lake-adjacent highways.
