Special Weather Statement issued November 20 at 3:19PM CST by NWS Chicago IL
Effective: Wed November 20, 2024, 3:19 PM
Expires: Wed November 20, 2024, 9:30 PM
A 2-3 hour long period of moderate to heavy snowfall is expected on Thursday during the late morning and early afternoon, likely leading to slushy snow accumulations occurring on roadways. Strong west-northwesterly winds gusting to 40-45 mph during the snowfall will cause sharply reduced visibilities, which will further exacerbate the hazardous travel conditions. Motorists should use caution when traveling in these conditions and allow for extra travel time to reach their destination.
