Madison, Wisconsin – A developing winter storm system could bring periods of snow and travel disruptions to parts of Wisconsin from Wednesday, Jan. 14, through Friday, Jan. 17, though confidence in severe impacts remains relatively low at this time.
According to the National Weather Service Weather Prediction Center, Wisconsin currently carries around a 20 percent probability for disruptive winter weather statewide. The state sits on the western fringe of a broader storm system expected to impact the Great Lakes and Ohio Valley more directly, meaning local impacts will depend on the storm’s final track and the timing of colder air.
The primary corridors to monitor include Interstate 94 from Madison to Milwaukee, Interstate 90 across southern Wisconsin, and Interstate 43 along the Lake Michigan shoreline. If snow develops, it would most likely occur during overnight or early morning hours, when temperatures are cold enough for slick road conditions. Even light accumulations could lead to hazardous travel on bridges, ramps, and untreated roads.
While widespread heavy snow is not currently expected, forecasters note that areas closer to Lake Michigan could see locally enhanced snowfall if winds align favorably. Farther north and west, precipitation may be lighter or more intermittent, limiting overall impacts.
Residents are encouraged to monitor forecasts closely, especially those with travel plans later this week. WisDOT advises checking road conditions and allowing extra travel time if winter precipitation materializes.
Forecast confidence is expected to increase over the next few days. While winter storm warnings are not anticipated at this time, localized advisories remain possible if snowfall potential increases or if colder air arrives sooner than expected.
