The episode as NWS ABR wrote it up.
A cluster of thunderstorm generated hail to the size of quarters 13 miles northeast of Ortonville. Heavy rain associated with these storms produced 2.22 inches of moisture measured by the COOP observer in Artichoke Lake. This was on top of 5.83 total inches in May. The heavy rain and runoff from saturated soils produced 20,000 dollars worth of flood related damage across Artichoke Township and 311,656 dollars worth of damage in adjacent Otrey township.

NWS Aberdeen, SD wrote its last area forecast discussion before the first event at Jun 2, 5:47 PM CST, 58 minutes earlier. Its key messages:
Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 647 PM CDT Sun Jun 2 2024 .KEY MESSAGES... - A slight risk of severe weather (level 2 on a scale of 5) will develop late this afternoon through the evening hours as a cold front sweeps across the area. All severe weather hazards are possible, including large hail, damaging winds, and tornadoes. - There is a 30-80% chance of showers and thunderstorms Monday night through Tuesday. && .UPDATE... Issued at 633 PM CDT Sun Jun 2 2024 Aviation discussion updated below for the 00Z TAFs. && .SHORT TERM /THIS EVENING THROUGH MONDAY NIGHT/... Issued at 207 PM CDT Sun Jun 2 2024 Showers continue to linger east of the Coteau this afternoon with ample cloud cover trailing back as far west as the James Valley. This will impede destabilization across the east as temperatures struggle to rise. That said, KABR did jump 8 degrees in the last hour to rise into the upper 70s, so any clearing at all will quickly push up temps. The best parameters for severe convection fall in the warm frontal zone extending off the sfc low and approximately stretching along the Hwy 14 corridor. Bulk shear around 40 kts, sig severe nearing 30 (80), and dewpoints in the mid 60s with CAPE up around 3000 J/kg support the HRRR's development between 22z and 23z of cells in Lyman/Buffalo/southern Hand and Hyde. There is less support the farther north you go apart from the shortwaves and cold front later this evening. Shear falls to 30 kts and CAPE to around 1500 J/kg with limited downdraft CAPE (700 to 800) as well. Still may see some stronger portions of a line develop and march east into Minnesota after 0z. Winds shift to the southeast on Monday ahead of the next approaching low. Showers and thunderstorms move back in with this next low Monday night, but storms are expected to remain sub-severe. && .LONG TERM /TUESDAY THROUGH SUNDAY/... Issued at 207 PM CDT Sun Jun 2 2024 An area of low pressure and associated frontal boundary will push eastward across the forecast area on Tuesday, bringing a 30-70% chance for showers and thunderstorms, mainly east of the James River. The front appears to push into MN during the mid afternoon hours, with the severe threat east of this CWA. Beyond Tuesday, the weather pattern will feature northwesterly flow aloft with mostly dry conditions prevailing. The northerly flow should produce favorable mixing winds with gusts of 25 to 40 mph possible throughout most of the period. Wednesday and Thursday should be the windiest days as the NBM has a 40-90% chance of seeing gusts exceed 40 mph. The probability of seeing 40 mph wind gusts drops below 45% Friday and Saturday. Temperatures will favor near average Wednesday and Thursday, with a cooling trend possible Friday and Saturday. The EC ensemble mean and the GEFS suggest highs in the upper 60s, to the mid 70s Friday through Saturday, while the GEPS is an outlier with highs in the 70s and 80s. && .AVIATION /00Z TAFS THROUGH 00Z MONDAY/... Issued at 633 PM CDT Sun Jun 2 2024 Terminals KABR,KATY,KPIR,KMBG TSRA/+TSRA will continue across the region through the evening hours, with periods of MVFR/IFR CIGs/VSBY with any activity that moves directly over a terminal. Also potential for hail and strong winds over 40 knots. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. && UPDATE...TMT SHORT TERM...Wise LONG TERM...SD AVIATION...TMT
