La Crosse, WI – Thunderstorms could interrupt Sunday afternoon plans across La Crosse, with the National Weather Service calling for a 40% chance of showers and storms after 1 p.m. Clouds will give way to gradual clearing, but not before localized downpours or brief lightning delays impact outdoor events. Highs will reach near 84°F, with gusts possible in stronger cells.
According to the National Weather Service, storm chances taper off after sunset, leaving behind mild overnight lows around 66°F. Monday will bring a notable shift — mostly sunny skies, calmer winds, and highs near 83°F. That trend continues through midweek, with Tuesday and Wednesday both expected to top out in the mid-80s under clear skies.
For residents and visitors, Sunday’s storm window may mean adjusting lake trips, farmers market visits, or ballgames to morning hours. The calm, sunny stretch starting Monday offers prime opportunities for outdoor dining, trail walking, and late-summer activities before heat and humidity tick up again later in the week.
Storm risks Sunday are brief, but summer’s intensity will return midweek, so staying hydrated and limiting peak-afternoon activity will be key as temperatures approach the upper 80s.
