Wisconsin – Bright sunshine and mild air are filling the Mississippi River Valley this morning, but a quick-moving system is lining up to bring rain and a sharp temperature drop that could create slick roads by early Friday.
According to the National Weather Service in La Crosse, dry and pleasant conditions hold through today with highs near 69°F. Winds remain light, making for an easy start to the day across western Wisconsin and nearby Minnesota communities.
Changes begin Thursday afternoon. Rain chances rise to 40% after 1 p.m., with scattered showers developing across La Crosse, Onalaska, and La Crescent. While rainfall looks light, roads including Highway 53 and nearby river crossings could become wet and briefly slick.
By late Thursday night, colder air moves in quickly. Temperatures fall to around 26°F, creating a window for any lingering moisture to freeze. Bridges and elevated roadways are most at risk, especially during the early morning commute. This setup raises concern for patchy black ice.
Drivers should slow down and allow extra time Friday morning. Watch shaded areas and river-adjacent roads where cold air settles first.
Cooler air lingers Friday with highs near 42°F, followed by a sunny but brisk Saturday. Conditions improve into Sunday, with temperatures rebounding into the low 60s and more stable spring weather returning.
