LA CROSSE, Wis. – Early Tuesday brings a quiet calm over the Mississippi River valley, the sky dim and heavy before the next round of light showers. Damp leaves rustle along neighborhood curbs as a mild breeze carries a hint of the cool-down to come. After a stretch of mostly cloudy skies, the region will soon slip into a clearer but colder Halloween stretch — the kind that signals November’s approach.
According to the National Weather Service in La Crosse, scattered light rain may develop late Tuesday afternoon and continue into the evening. The rain won’t be heavy, but roads such as Highway 14 and I-90 could turn slick for the evening drive. Showers fade by early Wednesday as drier, calmer air slides in from the northwest.
Wednesday shapes up mild, with highs in the mid-50s and sunshine returning for most of the day. Residents planning outdoor Halloween decorations or cleanup should take advantage before cooler air settles in. By Thursday, highs fall to the low 50s with partly sunny skies — pleasant during the day but chilly once the sun sets.
Friday’s Trick-or-Treat window looks cool and breezy, with evening temperatures near 40°F and a light north wind. Streets across La Crosse and Onalaska should stay dry, but layers and gloves are smart for little ghosts and superheroes heading out.
Looking ahead, the weekend brings mostly cloudy skies and highs in the 40s, marking a firm step into the late-fall chill. To be fair, the worst of winter isn’t here yet — but November’s colder rhythm is already tapping at Wisconsin’s door.
