The episode as NWS MPX wrote it up.
A decaying area of thunderstorms that developed across South Dakota Tuesday evening, June 29th, moved eastward over west central Minnesota. Although a couple of lightning strikes were noted near Redwood Falls, the severe wind gusts near Madison were not associated with thunderstorms. Scattered showers were noted in the area, but very dry air aloft and stronger winds in the boundary layer, allowed for the mixing of the stronger winds to reach the surface. A few wind sensors in Lac Qui Parle, and Yellow Medicine Counties had wind gusts above 57 mph.

Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 645 PM CDT Wed Jun 29 2022 .UPDATED for 00Z Aviation Discussion... Issued at 645 PM CDT Wed Jun 29 2022 && .DISCUSSION...(This evening through Wednesday) Issued at 314 PM CDT Wed Jun 29 2022 KEY MESSAGES: - A chance of thunderstorms late tonight through Thursday afternoon, a few could be severe. - Dry Friday, then more sporadic thunderstorms are possible Saturday into the middle of next week. Temperatures this afternoon range from the mid 70s over northwest WI to the upper 90s across western MN. The aggressive thermal ridging nosing into western MN this afternoon will overspread across the rest of the area tonight. That, in addition to a very dry atmosphere below 10 kft, will bring strong capping and no surface- based CAPE tonight. However, somewhat decent mid level lapse rates and increasing moisture AOA 10kft could lead to some modest elevated CAPE. A strengthening LLJ to 50-60 kts overhead late this evening will lead to breezy south winds, particularly on the Buffalo Ridge where gusts in excess of 45 mph are possible. Should storms that fire over the Dakotas survive their trek into MN overnight, then there could be some severe gusts with the deep dry layer below 10 kft and momentum transfer from the LLJ. CAMs do generate showers and some storms tonight, but the aforementioned negatives make me a little skeptical of the coverage of such activity. Kept PoPs in the 40-50 percent range, but that may be too high. A cold front will track across the Upper Midwest Thursday. Lingering thermal ridging along the front should allow highs to reach the lower 90s across southern and eastern MN. Morning clouds may keep highs cooler in WI, and the frontal passage should bring cooler air aloft early in the day across western MN. Daytime heating and some pooling of low level moisture along the front may help develop some thunderstorms during the afternoon across southern/eastern MN into WI. Significant speed shear could organize the storms into line segments capable of wind and hail. Thursday's severe set up appears much more favorable than tonight's. Cooler and drier air will follow Friday. The trough will lift out this weekend, bringing back a pattern similar to today's west northwest flow. This should allow occasional disturbances to spill east southeast over the northern Plains and bring chances for thunderstorms for the rest of the forecast period. A stronger disturbance still may take shape Monday and Monday night, which is when the highest chances reside. Model consistency with this feature has not been good - not too surprising. However, deep moisture lifting north interacting with a better defined shortwave could bring complex(es) of thunderstorms capable of heavy rainfall and some severe weather. The holiday weekend is not expected to be a washout, but Independence Day itself bears some watching. && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 645 PM CDT Wed Jun 29 2022 Continued gusty winds and VFR conditions this evening. Overnight storms over the Dakotas will continue to the east into Minnesota. With lots of dry air to overcome near the surface confidence is not high that these storms will survive so have kept PROB30 in the TAFs where allowed. With a strong low level jet tonight LLWS will be a concern. Calmer winds tomorrow with another chance for TSRA late Thursday. KMSP... Same concerns as above chance for -TSRA between 09 and 12Z. Also LLWS concern overnight as the low level jet picks up. /OUTLOOK FOR KMSP/ Fri...VFR. Wind NW 10-15 kts. Sat...VFR. Chc -TSRA. Wind S 5-10 kts. Sun...VFR. Wind light at 5 kts. && .MPX WATCHES/WARNINGS/ADVISORIES... MN...None. WI...None. && DISCUSSION...Borghoff AVIATION...NDC
