Area Forecast Discussion National Weather Service La Crosse WI 124 PM CDT Wed May 27 2026 .KEY MESSAGES... - Another shot (20-50%) for showers and thunderstorms this afternoon and evening. A strong thunderstorm or two may develop. - Above normal temperatures continue through the weekend. && .DISCUSSION... Issued at 123 PM CDT Wed May 27 2026 Shower and thunderstorm potential this afternoon/evening 17z WV satellite shows northwesterly flow aloft over our forecast area with a weak disturbance in this flow over western Lake Superior. At the surface, a cold front is located over northern WI. This afternoon and evening, as the weak disturbance moves southeast and the backdoor cold front begins to push through the area, showers and thunderstorms may develop. With warm surface temperatures and dewpoints once again in the 60s, would seemingly expect a similar outcome to yesterday but with convection favoring our east, away from the upper ridge building over the eastern Dakotas. Compared to yesterday, mid levels are drier and am thus concerned that updraft attempts may struggle. Have therefore kept PoPs in the 20-50 range for now. In any case, deep boundary layer continues to indicate a risk for a stray severe gust and, with deep shear just a touch stronger than Tuesday at around 25 knots, could see a stray severe hail report once again. Above normal temperatures ahead Guidance continues to point toward persistent upper ridge over the central CONUS with cyclonic flow centered in eastern Canada. After a post-frontal day with temperatures near normal Thursday and Thursday night, temperatures return to the 80s for Friday through next Tuesday. As time goes on and the upper ridge slowly weakens, could get some afternoon/evening convection Sunday through Tuesday but confidence in details is very low at this time. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1225 PM CDT Wed May 27 2026 VFR conditions expected through the TAF period. A weak boundary dropping south through WI later this afternoon and evening will carry a 30 to 40% chance of triggering some thunderstorms. LSE would be on the western periphery of this storm potential so have included a PROB30 to the TAF this evening. Otherwise light winds will pick up out of the east tonight, becoming a bit breezy at RST with gusts around 20 knots. Some guidance suggests a small chance of MVFR ceilings at RST closer to daybreak Thursday, but confidence is low. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...None. MN...None.
