Madison, Wisconsin – Wind gusts up to 45 mph will sweep across southern Wisconsin by late Thursday morning, raising fire concerns and creating difficult travel on east-west roads before rain changes to light snow after midnight Friday.
According to the National Weather Service in Milwaukee/Sullivan, a Wind Advisory runs from 9 a.m. to 6 p.m. Thursday for much of the region, including Madison, Janesville and Waukesha. Southwest Wisconsin counties such as Lafayette, Iowa and Green could see peak gusts near 45 mph. Warm temperatures in the 60s combined with low relative humidity will elevate fire danger, and outdoor burning is discouraged.
Rain develops during the day Thursday, especially along and south of I-94. By midnight into early Friday morning, colder air filters inland, allowing a transition to a wintry mix and wet snow west of Lake Michigan. Most inland communities, including Madison and Wisconsin Dells, could see a light slushy accumulation under 1 inch between midnight and 9 a.m. Friday. Roads may turn slick briefly on bridges and overpasses along US-151 and I-90.
Closer to Lake Michigan, including Milwaukee, Racine and Kenosha, warmer air may keep precipitation mainly rain, limiting snow accumulation. Forecasters note dry air could reduce totals further, and some lakeshore areas may see no measurable snow.
Drivers should secure loose outdoor items today, use caution on high-profile vehicles during peak winds, and allow extra time for the Friday morning commute. Additional advisories may be issued if colder air arrives faster than expected early Friday.
