La Crosse, Wis. – Summerlike warmth will give way to unsettled fall weather in western Wisconsin by late Sunday as showers and thunderstorms develop, raising the risk of slick roads and localized delays.
According to the National Weather Service in La Crosse, highs will soar into the upper 80s Friday and Saturday under mostly sunny skies. Gusty south winds near 25 mph could make outdoor events breezy but comfortable. The calm stretch ends Sunday evening, when a system sweeps across the Upper Mississippi Valley. Rain and storms may bring heavy downpours and gusty winds, especially along I-90 and into the Coulee Region.
The NWS notes a 50 percent chance of showers and thunderstorms Sunday night, with rain continuing into Monday. Motorists should plan for reduced visibility and slower commutes, particularly during the Monday morning drive. While severe storms are not guaranteed, forecasters caution that frequent lightning and localized ponding are possible.
Temperatures cool into the 60s early next week, signaling the shift toward a more seasonable fall pattern. Outdoor plans, including harvest activities and youth sports, may face interruptions from scattered showers. Residents are advised to secure loose items ahead of gusty winds, allow extra travel time, and keep devices charged in case of brief power interruptions.
Drier conditions return by midweek, though isolated showers could linger into Wednesday and Thursday.
