Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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.

Issued at 102 PM CDT Wed Jun 10 2026 The latest RAP analysis and satellite/radar imagery show a potent northern Plains trough is lifting northeast into south-central Canada, pushing a cold front east across western Minnesota. An effective warm front extends from near Minneapolis to Fond Du Lac early this afternoon, establishing a volatile and highly unstable warm sector across southern Wisconsin. Even further south, an shortwave impulse and associated convection over Iowa and southeast Minnesota is primed to track northeastward, providing large- scale ascent later today. Severe Thunderstorm Potential This Afternoon/Evening: Destabilization is expected this afternoon as this mornings thunderstorm activity has exited. Extremely strong instability resides south of the warm front, where surface- based CAPE values are ramping into the 3000-4000 J/kg range, driven by surface temperatures warming into the middle 80s and dewpoints pooling into the middle 70s. Steep mid- level lapse rates of 7-8 C/km and downdraft CAPE in excess of 1000 J/kg point to a volatile airmass highly favorable for severe weather. As a shortwave impulse tracking out of Iowa provides deep layer forcing, storms are expected to gradually intensify as they shift northeastward between 3 PM and 8 PM. Convective evolution carries some uncertainty, as high- resolution guidance splits between a consolidated cold pool bowing system and discrete clusters or broken line segments. Damaging wind gusts and large hail are the primary threats. However, an isolated tornado threat cannot be ruled out near the effective warm front across central to east- central Wisconsin where low- level flow is locally backed. The greatest severe threat is expected south of a Rhinelander to Manitowoc line where a Severe Thunderstorm Watch is in effect. Some CAMS indicate develop additional thunderstorms along the cold front due to move across the region late this evening. While expectation is that the atmosphere will be worked over thereby limiting buoyancy potential, an isolated strong storm will be possible. The threat of storms will diminish by early overnight. Thursday Severe Potential: The main surface cold front will settle downstate overnight. After a lull Thursday morning, a very dynamic shortwave trough will drive a surface low pressure system northeastward across the region Thursday afternoon into early Thursday evening. Model spread remains rather large regarding the exact track of the surface low, leading to below normal forecast confidence. The general consensus navigates the surface low across east-central Wisconsin late Thursday afternoon. Areas south of this track will possess the highest severe weather threat. Instability will be substantially lower than today, maxing out near 1000 J/kg, but wind fields will be considerably stronger. Given the robust wind fields aloft, significant instability will not be required, just sufficient for severe weather. Damaging winds and an isolated tornado will be possible from the lows triple point southward, placing east-central Wisconsin at the greatest risk for severe weather. Sfc highs will range from the mid 70s to low 80s. Friday Wind and Marine Impacts: A cooler and drier weather pattern returns on Friday in the wake of the departing surface low as a longwave trough establishes itself from Hudson Bay into the western Great Lakes. A tight pressure gradient on the southern periphery of the trough will foster breezy conditions across the entire area. Sfc wind gusts of 30 to 35 mph are expected over land, and these strong winds will likely necessitate a Small Craft Advisory across the nearshore waters of Lake Michigan and Green Bay due to building waves. Weekend and Extended Outlook: Spotty showers and storms will linger over north-central Wisconsin Thursday night behind the main surface low, but dry conditions return for most locations by Friday morning. Saturday looks to be the more active day of the weekend as a secondary cold front drops south. Instability will moderate to around 500-700 J/kg by Saturday afternoon, which when combined with mid-level wind fields of 30-50 kts, will support a few storms capable of gusty winds. Behind this second front, a distinct cooling trend takes hold. Temperatures in the low 70s to low 80s through Saturday will fall back into the mid 60s to mid 70s from Sunday through Tuesday. The next appreciable chance for widespread rainfall will arrive on Tuesday as a northern stream shortwave digs into the western Great Lakes. && .AVIATION...for 00Z TAF Issuance Issued at 623 PM CDT Wed Jun 10 2026 Showers and scattered thunderstorms across northeast WI will exit the area by 03z. Meanwhile, scattered showers and storms across western WI will move into the area during the early to mid evening hours. Uncertainty exist is they would make into northeast WI late this evening. Any patchy MVFR CIGs will dissipate this evening with VFR conditions prevailing. Fair weather cumulus between 1,500 and 3,000 feet will develop Thursday morning. The next round of strong or severe storms Thursday afternoon. Wind gusts to or over 50 knots will be possible. && .GRB WATCHES/WARNINGS/ADVISORIES...
