The episode as NWS ARX wrote it up.
Scattered storms moved across portions of southeast Minnesota during the late afternoon of June 28th. These storms produced a 60 mph wind gust in Rochester (Olmsted County) that blew down some trees. At least one of the trees landed on a house. Golf ball sized hail fell in Grand Meadow (Mower County).

NWS La Crosse, WI wrote its last area forecast discussion before the first event at Jun 28, 1:21 PM CST, 3 hours 17 minutes earlier.
Area Forecast Discussion National Weather Service La Crosse WI 221 PM CDT Tue Jun 28 2022 .DISCUSSION...(This evening through Tuesday) Issued at 216 PM CDT Tue Jun 28 2022 Key Messages: - Strong to severe storms possible heading into this evening - Precipitation chances return Thursday - On and off precipitation chances through holiday weekend STRONG TO SEVERE STORMS POSSIBLE THIS EVENING: A shortwave trough currently located over northern Minnesota is set to side southeast across central Wisconsin early this evening. A cold front accompanying the wave currently extends from far southwest Minnesota up to Bayfield, Wisconsin. Along and ahead of the cold front, storms are expected to continue to develop this afternoon as the front moves southeast. Storms will arrive to our forecast area early this evening, with the potential for some storms to be strong to severe. Instability and shear are both marginal to moderate today with 750- 1250 J/kg of ML CAPE along a majority of the front and 0-6km shear around 35 knots. Our area of highest concern lies in southeast Minnesota where CAPE could reach upwards of 2000 J/kg collocated with 40-knot 0-6km shear. However, a stronger cap in southeast Minnesota could delay or inhibit convective initiation so there is still some uncertainty in the western extent of the thunderstorm risk. Dewpoints are currently in the mid 50s for most and could rise into the low 60s as the front approaches, especially in southeast Minnesota. The trend throughout the morning has been a slower advection of higher dewpoints across the area which could slow the progression of stronger storms. Lastly, showers and storms that moved across the area earlier today could limit the amount of energy left in the atmosphere and lower strong/severe chances, especially in the Clark County region of central Wisconsin. A somewhat unimpressive set up but a few strong/severe storms remain possible with damaging wind and hail the main threats. Initial convection up in northern Wisconsin is congealing into a line which could increase the damaging wind potential if it holds together as it moves southeast. Cool air aloft and lapse rates around 7 C/km could support hail development as well. PATCHY FOG TOMORROW MORNING: After storms vacate the area, clearing skies, light winds, and low dewpoint depressions could lead to patchy fog across our Wisconsin counties tonight. NBM and NBM 4.1 guidance suggests there is a 40% chance for visibilities to drop below 5 miles across most of Wisconsin with some lower visibilities also possible in northeast Iowa and along the Mississippi River in southeast Minnesota. Use caution during the morning commute tomorrow if fog develops. PRECIPITATION CHANCES RETURN THURSDAY: Thursday looks to be the warmest day of the next several days. Ahead of the next shortwave as a weak upper-level ridge slides further off to the east over the Great Lakes Region, low level winds increase from the south. A decent warm air advection signal in the lowest layers of the atmosphere up through 700 mb would limit overnight temperatures from significantly lowering. Some locations may struggle to dip below 70 degrees with much of the region barely getting into the mid 60s by early Thursday morning. Increasing cloud cover from the west from scattered showers/storms would also help limit any radiational cooling mainly for areas in southeast Minnesota into north central Wisconsin. As the surface boundary approaches the region, precipitation chances by Thursday morning look to hold mainly north of I-90 with scattered shower/storm development aligning from southwest Minnesota into north central Wisconsin. The morning could also be the windiest period with the increasing low-level jet. Both the NAEFS and EC ENS 28.00z guidance has the mean wind speed maxed out in regards to climatological percentile at 850 mb. The zonal and meridional winds are also maxed out or in the top 99.5 percentiles. Surface winds could gust around 30 to 35 mph overnight into the morning before the low level jet relaxes heading into the afternoon. The precipitation activity also looks to diminish becoming more scattered through the afternoon, but any lingering localized and elevated showers will impact the high temperatures. Any new convection will be limited do to the strong capping inversion maximized around 800 mb as depicted in forecast soundings due to the ample overnight WAA. As the front progresses further southeastward through the region into northeast Iowa and southwest Wisconsin, lapse rates increase in the 800 mb layer allowing for showers to reignite across this area. ON/OFF PRECIPITATION CHANCES THROUGH HOLIDAY WEEKEND: Stuck with the blended model guidance through the Independence Day Holiday as model and ensemble guidance diverge from one another. There are low (15-30%) chances for precipitation throughout this period. However, expecting these to be more periodic with more dry time than not, so not expecting a complete washout. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 1235 PM CDT Tue Jun 28 2022 VFR conditions are expected until storms approach the area this evening. Storm chances are increasing at both LSE and RST with better coverage possible near LSE. Ceilings are not expected to fall below VFR but visibilities could drop during periods of heavy precipitation. Southwest winds with some gusts up to 25 kts this afternoon will become light and northerly after a cold front/storms pass through the area. There is a 40% for visibilities to fall below 5 miles with a chance for patchy fog to develop near LSE tomorrow morning due to light winds, clear skies, and low dewpoint depressions. Fog may need to be added into the TAF if confidence increases. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...NONE. MN...NONE. IA...NONE. && DISCUSSION...KAA/Peters AVIATION...KAA
