The episode as NWS ARX wrote it up.
Thunderstorms developed during the afternoon of June 15th ahead of a cold front. As these storms moved across central Wisconsin, they dropped large hail and produced some damaging winds. The largest hail size reported was egg sized south of Big Flats (Adams County). An estimated 70 mph wind gust was reported near Monroe Center (Adams County) which blew down several trees damaged homes.

NWS La Crosse, WI wrote its last area forecast discussion before the first event at Jun 15, 1:48 PM CST, 57 minutes earlier.
Area Forecast Discussion National Weather Service La Crosse WI 248 PM CDT WED JUN 15 2016 .SHORT TERM...(This evening through Thursday) Issued at 245 PM CDT Wed Jun 15 2016 watching storms as they march east for the next hours. We expect the threat to be east of the Clark and Taylor by 330 pm...and the remaining counties along and north of I-94 by 5 pm. MLCAPE is building ahead of the surface cold front, from east of KEAU to KONA and southwest. However...the sunshine and increased mixing depth is veering much of the flow to westerly in the warm sector with very little convergence along the front south of a Black River Falls to Wisconsin Rapids WI line. Further east, the warm front is located along a line from northeast of KMDZ to KFLD...basically east of Adams county. Thus the tornado threat with a lower level curved hodograph has shifted east as well. Thus...young storms across Clark and Taylor county and lack of convergence further south dont bode well for severe weather. But, cannot completely rule it out either. Deeper shear is now in the supercell range...so will have to watch for a sustained updraft in somewhat more stable mid-level lapse conditions. an isolated large hail or wind gust to 60 mph could occur...but we think this will remain very isolated. Overnight the cyclone will continue southeast and with it comes the widespread clouds now seen in MN. It appears the western edge of the cloud field will be in the KLSE-KRST vicinity by morning with some pesky cloud and slow dissipation over WI for much of Thursday. .LONG TERM...(Thursday night through Wednesday) Issued at 245 PM CDT Wed Jun 15 2016 With the strong ridging building into place...it appears no impact weather will take hold through the weekend. the latest trends on saturday night and sunday are to slow the frontal speed and strong capping builds in during that period. The 15.12Z GFS MLCIN at KRST at 4pm Sunday is over 200 J/kg with a 700 mb temperature of 12-14C. This is also supported in the 15.06z GFS and latest 15.12z ECMWF run. This isnt conducive for rain chances so the slight chances for rain were removed. There are suggestions that a number of favorable atmospheric conditions could be in place for a very warm Fathers Day. A pre- frontal warm prod of air, stronger capping, and a good low-level gradient to enhance mixing could lead to highs above current forecast and guidance. For now, have bumped the Sunday temperatures about 2-3F above the consensus guidance forecast. It is still out 4 days. Sunday night through Tuesday, the larger scale flow transitions from ridge to northwest flow and troughiness. the cold front associated with this transition looks to now time through in the sunday night to monday time frame and with the air mass in place, could pose a severe weather risk, including heavy rains. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1241 PM CDT Wed Jun 15 2016 The strong June sun helped clear out the morning stratus quickly. VFR conditions now look to prevail through the evening as a breezy westerly wind draws in somewhat drier air. The winds look to diminish some in the evening with loss of daytime heating. During the overnight hours, as low pressure currently near Duluth slides into Lower Michigan, low clouds in its wake looks to march southwestward towards the TAF sites. Brought MVFR stratus into KLSE around 10Z and IFR stratus into KRST at 12Z. Daytime mixing, combined with a ridge of high pressure building in Thursday morning from the west, should help scatter out KRST around 16Z while bringing ceilings up some at KLSE. KLSE looks to scatter out Thursday afternoon. && .HYDROLOGY... Issued at 245 PM CDT Wed Jun 15 2016 The area continues to recover from the overnight heavy rains and the dry period through Sunday is good news! There will be some threat for heavy rain again early next week but this should remain progressive and could change as we approach that Day 5-6 forecast. Overall...most rivers are falling and county road crews are working on secondary road washouts and closures. && .ARX Watches/Warnings/Advisories... WI...None. MN...None. IA...None. && SHORT TERM...BAUMGARDT LONG TERM...BAUMGARDT AVIATION...AJ
