The episode as NWS MPX wrote it up.
A decaying thunderstorm complex moved across the region on the morning of June 24 and produced a wake low that caused gusty non-thunderstorm winds. Flying Cloud airport in the Twin Cities gusted to 62 mph.
Later that afternoon a few storms developed and produced a couple funnel clouds and sub-severe hail.
A third round of storms developed during the evening and produced one report of severe hail.

Area Forecast Discussion...UPDATED National Weather Service Twin Cities/Chanhassen MN 626 AM CDT Sat Jun 24 2023 .DISCUSSION...(Today through Friday) Issued at 255 AM CDT Sat Jun 24 2023 KEY MESSAGES: - Thunderstorms expected today into tonight, some could be strong with wind and hail as the main threats. - Rain lingers into Sunday, some isolated thunder possible, with the next chance for rain mid to late next week. - Cooler, closer to normal temperatures, over the next week. Today... Today the main low will move into Minnesota and with it we will see our best synoptic lift and best chance for rain. This combined with precipitable water values around 1.5 inches will give us the ingredients for heavy rain. On the convective side ample shear, which we have seen little of so far this year, could support some stronger storms. With a cooler day today through we are not expecting as much instability to build, but if we can clear out for part of the day to really heat up this will increase the chances for strong storms this afternoon. Also a factor for later today will be how the convection over South Dakota evolves as it moves east. Looking into the CAMs, especially the HRRR, there is an expectation of this linear system holding together into Iowa and maybe even parts of southern Minnesota. The southern end of the line has looked better in radar observations and in the CAMs, but how far north it will hold together remains a question. Looking at an ensemble like the HREF it does appear most likely to see this line weaken as it moves east allowing us time for convective recovery for the main round of thunderstorms to occur in the afternoon and evening today. For hazards the greatest risk in the morning would be wind, especially if the linear storm mode holds. Later today more discrete to scattered multicells are favored with more of a hail threat. Tornadoes also cannot be ruled out as forecast LCLs look the become rather low by this evening and this combined with sfc to 1 km SRH in the HRRR in the 150 to 200 m2/s2 range would provide a supportive environment for rotating storms. Bottom line today is the most favorable environment for strong to severe storms that we have seen so far this year, so if you have outdoor plans make sure to have a way to keep updated with the weather. Some storms should continue into tonight, but as an MCS is not expected, so the loss of the diurnal heating should lead to a reduction in the severe threat. Sunday... As the main low moves east on Sunday we will move into the wrap around side of the low. This will be an environment more favorable to rain showers than thunderstorms. We could still see some thunderstorms, but nothing severe is expected. The back of the low will also see cooler temperatures with forecast highs only in the lower 70s. Rain chances decrease throughout the day as the low continues to move farther east. Monday through Friday... We move into a more typical June pattern next week with near normal temperatures, highs around 80, and a few chances for rain mid to late week. The week will start dry as higher pressure moves in behind this weekend's system. By midweek our next system looks like it will move in. This system continues to look less significant compared to the weekend system with lower QPF across ensemble members. The overall timing and placement over the Upper Midwest has reasonable agreement, but QPF amounts and exact locations still vary. && .AVIATION...(For the 12Z TAFS through 12Z Sunday morning) Issued at 626 AM CDT Sat Jun 24 2023 The main story today will be multiple rounds of rain showers or thunderstorms. This does not mean continual MVFR or lower today, but periods of MVFR or IFR as the showers/thunderstorms move through today. The first round will mainly impact RWF and MKT and they could still see TSRA with other terminals more likely to see rain from this initial line this morning. More thunderstorm development this afternoon and evening which will have locally high gusts and MVFR to IFR conditions. Low MVFR to IFR expected tonight into Sunday morning with continued -SHRA and BR. KMSP... This initial line this morning should fall apart as it approaches the terminal area. Could still see some rain, so opted for a TEMPO. Biggest impacts today will be this afternoon and evening as another round of TSRA is expected. This will likely have at least MVFR with IFR likely at times as well. This timing can be further refined in future TAFs. Lingering rain into tonight will keep the terminal in MVFR. /OUTLOOK FOR KMSP/ Sun...MVFR/-SHRA, chc -TSRA. Wind NW 10-20G25kts. Mon...VFR. Chc -SHRA. Wind NW 15G25kts. Tue...VFR.
