Overview
|
Multiple rounds of severe thunderstorm pushed through southern and central Wisconsin on Saturday evening, July 23, 2022 into early Sunday morning, July 24, 2022. This brought widespread wind damage across the area along with a few large hail reports southeast of Madison and a few funnel cloud reports in Dodge County. Additionally, these storms also brought area widespread rainfall with amounts up to and even exceeding 4 inches, especially where multiple storms moved over the same area. Saturday morning began with a round of scattered thunderstorms across the southern tier of the state. Most of these storms produced sub-severe hail, but one storm around 6 AM produced localized damaging winds around the Sturtevant and Racine area. The morning activity cleared out quickly allowing hot and humid conditions to develop across southern Wisconsin through the afternoon. This along with an approaching cold front and upper-level forcing aligning, helped set the stage for a favorable environment to fuel the multiple rounds severe thunderstorms through the evening. SPC issued two Severe Thunderstorms Watches through the event, while MKX issue numerous severe thunderstorm warnings. Additional information about the event can be found here: |
 Local Storm Reports from July 23-24, 2022 |
First Round of Severe Thunderstorms:
 MKX - Radar loop of base reflectivity from 4:30PM - 9:00 PM CDT July 23, 2022 |
The first round of severe storms developed across central Minnesota late morning/early afternoon and tracked east-southeast into western Wisconsin. Storms began to merge into a line around 4 PM CDT and push into the area. Damaging winds were the main concern with the line, especially where any bowing features developed and numerous wind damage reports occurred. However as the line pushed further east, the western edge of the line took on more of a supercell structure across Dane County. This supercell tracked southeast across Rock County, where in addition to damaging winds also produced large hail up to 2 inches around the Lake Koshkonong area. This supercell continued into Walworth county before weakening. The first line of severe thunderstorms pushed out over Lake Michigan around 8 PM CDT. |

Second Round of Severe Thunderstorms:
 MKX - Radar loop of base reflectivity from 9:00 PM CDT July 23, 2022 - 12:30AM CDT July 24, 2022 |
A second round of severe thunderstorms quickly developed across Marquette and Green Lake counties. This round produced another supercell, which tracked southeast across Dodge county. Rotation was evident on radar and there were multiple reports of funnel clouds associated with this storm. However, there has not been any evidence of a tornado at this time and most damage was related to straight lined winds. The supercell eventually evolved more into a linear structure and continued to produce wind damage, most notable across West Bend and Brown Deer areas before pushing out over Lake Michigan around midnight. Additionally, these storms and its heavy rain moved over a similar area as the previous round leading to flooding across Washington, Ozaukee, northeastern Waukesha, and northern Milwaukee counties counties. |

Third Round of Severe Thunderstorms:
 MKX - Radar loop of base reflectivity from 12:00 AM - 3:30 AM CDT July 24, 2022 |
Despite the previous storms, the environment remained supportive for another round of severe thunderstorms, thanks in part to a strong low-level jet developing across southern Wisconsin. This third round began to take shape across western Wisconsin and northeast Iowa. As the line pushed eastward with the northern portions taking on mesoscale convective vortex structure, the storms were able to easily mix down stronger winds aloft and multiple reports of winds in excess of 60 mph came in across southern Wisconsin. Then the line weaken as it pushed into the lake counties, but gusty winds were still occurring with the lingering shower activity. |
