Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area Forecast Discussion National Weather Service La Crosse WI 215 PM CDT Wed Jun 24 2026 .KEY MESSAGES... - Strong to severe storms this afternoon and evening, mainly along and east of the Mississippi River. The main hazards will be large hail and damaging winds with a low but non-zero tornado threat. - Temperatures gradually warming into the weekend - Hot and humid conditions expected Sunday through mid next week with triple digit heat indices looking more probable (40-70%) && .DISCUSSION... Issued at 205 PM CDT Wed Jun 24 2026 Today: Strong to Marginally Severe Storms Isolated to scattered storms have popped up across the Upper Mississippi River Valley early this afternoon. Thus far, much of the activity has been rather pulse-like in nature: coming down almost as quick as they're going up. A few have been able to sustain themselves for longer than 15-30 minutes and have been able to produce some dime size hail. As the atmosphere continues to destabilize this afternoon, forcing will only continue to push further east with a cold front at the surface and a short wave trough in the mid/upper levels draped across the Upper Midwest. 24.17 RAP analysis suggests 1000+ J/kg of MLCAPE already present across the area with effective shear around 30-40 kts. So far it seems the modest shear has been what's holding the activity back but as this increases over the coming hours, an increase in supercellular structures will be possible. The main hazard with any storms today will likely be large hail given the seasonably cool temperatures aloft, even though lapse rates aren't particularly impressive. Damaging winds will be a possibility, especially on the southern end of the risk area (southwest Wisconsin) with drier air in the mid/low levels leading to slightly higher levels of DCAPE. While the tornado threat looks pretty low overall given the straight hodographs (meaning splitting cells are more likely overall) and decently high LCLs, some weak low level helicity could lead to a brief spin up this afternoon. The threat for strong to severe storms shifts to the east through the evening hours as the frontal boundary and shortwave push off towards the Great Lakes. Thursday - Saturday: Warming Up Generally benign conditions expected for the end of the week and into the early portions of the weekend. Upper level flow will turn zonal with weak surface high pressure sitting over the Upper Midwest. This high pressure looks to keep a stationary front to our south Friday into Saturday. Temperatures through this time period will be on an upward swing in the upper 70s to mid 80s by Saturday. Dew points will also be on an upward trend with mid 50s Thursday and Friday and upper 50s to mid 60s on Saturday. And it only gets worse from there... Sunday - Early Next Week: Hot and Humid A longwave trough is expected to deepen over the Western CONUS this weekend. In response, a high amplitude ridge is expected to build from the Lower Mississippi River Valley into the Upper Midwest and Great Lakes by Sunday into Monday. With it, a surge of warm gulf air will surge north. The 850 mb thermal ridge will also set up across the northern plains with 850 mb temps on the order of 10-15 deg C above normal for early summer. As such, surface temperatures will soar into the upper 80s to mid 90s with dew points in the upper 60s to mid 70s. This could lead to triple digit heat indices and the need for heat headlines. The heat is expected to linger into at least mid week with chances for rain each day as shortwave impulses traversing the ridge interact with the abundant moisture across the area. Whether these storms will be strong to severe is unknown as significant uncertainty with this activity remains. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1237 PM CDT Wed Jun 24 2026 MVFR/IFR CIGs have finally eroded across the area with mostly VFR conditions currently present. Storms have started to pop up across portions of the area, primarily across Southwest and West Central Wisconsin. With additional development expected along and just west of the Mississippi River in the coming hours with a passing weak cold front, have included a TEMPO group at LSE to account for the potential for storms this afternoon. Storm coverage will then shift east of the river and away from the terminals. The rest of the period will then feature generally benign conditions with west to northwest winds at or below 10 kts. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...None. MN...None.
