La Crosse, WI – Wisconsin’s summerlike grip holds firm as September heat mixes with storm chances in La Crosse this week. Temperatures climb near 90 Tuesday before showers and thunderstorms threaten to slow travel midweek, especially along I-90.
According to the National Weather Service, Tuesday will bring mostly sunny skies with highs around 88. Storm chances rise Tuesday night into Wednesday, with scattered showers likely in western Wisconsin. The heaviest rain could develop late Wednesday, leaving slick roads and slowing the evening commute.
La Crosse County residents should watch for lightning and brief downpours Wednesday morning through night. Motorists on I-90 and U.S. Highway 53 may face visibility issues. Emergency officials urge drivers to reduce speed in heavy rain and keep headlights on.
After storms taper Thursday, highs will dip slightly, but daytime readings stay in the 80s through week’s end. Nights remain mild, hovering in the low to mid-60s, making this stretch feel more like July than mid-September.
Friday could bring another round of showers before a drier pattern returns Saturday. The weekend looks seasonable with daytime highs in the mid-70s. By Sunday, sunshine dominates again, hinting at a more fall-like trend ahead.
