La Crosse, WI – Patchy fog will linger early Monday, but the bigger concern this week arrives Tuesday when thunderstorms could bring lightning and locally heavy rain to western Wisconsin. The National Weather Service says storms are most likely between 1 p.m. and 7 p.m., with the peak risk around late afternoon in La Crosse County and neighboring areas.
According to the National Weather Service in La Crosse, the chance of storms Tuesday is around 30%, with some cells capable of producing brief downpours and gusty winds. Travelers on I-90, U.S. 53, and local county roads should be alert to changing conditions. Lightning poses the greatest hazard, making it wise to reschedule outdoor activities such as youth sports or evening events.
After the storms move through, skies will clear Tuesday night, setting up a stretch of sunny and seasonable weather through midweek. Wednesday and Thursday will be warm and dry, with highs in the low to mid-80s—ideal for outdoor work, festivals, or late-summer lake trips.
The NWS advises keeping an eye on updated forecasts Tuesday morning for any upgraded alerts.
