Special Weather Statement issued January 14 at 4:50AM CST by NWS Chicago IL
Effective: Wed January 14, 2026, 4:50 AM
Expires: Wed January 14, 2026, 10:00 AM
A band of gusty snow showers along a strong cold front extended back to southwest Wisconsin as 4:50 AM CST. These snow showers can be expected to move steadily south across the area between 6 AM and 11 AM CST. Embedded bursts of heavier snow may tend to focus east of I-39, which when paired with northerly winds gusting to 35 to 40 mph, may reduce visibility below one mile at times. A coating to around a half inch of snow may accumulate on colder or untreated surfaces, with localized one inch amounts possible in far northwest Indiana. With temperatures starting above freezing and then quickly falling into the 20s with the snow, slick spots may develop on some roads. Motorists are advised to leave extra time to reach their destinations this morning and be prepared to encounter localized hazardous travel. Take it slow and keep a safe following distance when driving.

Gusty winds behind a cold front are expected this morning. Sustained winds of 15 to 25 mph and gusts of 35 to 40 mph are expected. An errant gust to 45 mph is also possible. Drivers of vans, campers, trailers, and other high profile vehicles should be extra cautious, especially on east-west roads. Be sure to secure outdoor items as well. Winds this afternoon will be lower. Snow showers are also possible north and east of a line from Manchester, Iowa to Cambridge, Illinois. Brief reduced visibilties of 1 to 2 miles and isolated slick spots are possible in the most intense showers this morning. No snow accumulation is expected at this time.

Expires: Wed January 14, 2026, 9:00 AM
The combination of snow and high wind gusts to 35 miles per hour have severely limited visiblity this morning down to 1/2 mile in spots, leading to hazardous driving conditions for the morning commute. If you need to travel this morning, please leave extra time and slow down and leave room for extra stopping distance.
