The episode as NWS ARX wrote it up.
A cold front moved east across western Wisconsin during the late afternoon and evening hours of June 1st. This allowed scattered thunderstorms to develop and track across portions of western Wisconsin. The thunderstorms knocked down a tree onto power lines and caused power outages in the city of Thorp (Clark County) and hail damaged apple trees on a farm in Crawford County.

NWS La Crosse, WI wrote its last area forecast discussion before the first event at Jun 1, 2:05 PM CST, 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 305 PM CDT TUE JUN 1 2010 .SHORT TERM...TONIGHT THROUGH FRIDAY FORECAST FOCUS IS ON THE PCPN CHANCES FOR TONIGHT INTO WED...FOLLOWED BY THE NEXT RAIN THREAT ON FRIDAY. BAND OF SHOWERS/STORMS CONTINUE ALONG AND JUST WEST OF A COLD FRONT...STRETCHING FROM NORTHEAST WI INTO WESTERN IA. THE BAND IS FEEDING ON ABOUT 1000 J/KG MLCAPE WITH EFFECTIVE SHEAR AROUND 30 KTS. BUFKIT SOUNDINGS CONTINUE TO POINT TO AN INVERTED-V SHAPE IN THE NEAR SFC LAYER...WITH THE STORMS MOVING INTO A RELATIVELY DRY REGION AS SFC DEW POINT DEPRESSIONS OVER NORTHEAST IA/SOUTHWEST WI ARE AROUND 35 DEGREES. SFC MOISTENS UP PRETTY QUICKLY AS THE STORMS MOVE IN. CONDITIONS CONTINUE FAVORABLE FOR STRONGER STORM RELATED WIND GUSTS...AND LARGER HAIL CAN/T BE RULED OUT EITHER. SEVERE THREAT LOOKS LOOK AT THIS MOMENT...BUT THE STORMS WILL BE MONITORED CLOSELY THROUGH THE EARLY/MID EVENINGS HOURS. OVERNIGHT...THE BOUNDARY WILL CONTINUE TO SINK TO THE SOUTH...BUT THE LOW LEVEL JET/MOISTURE TRANSPORT WILL REFOCUS INTO AND NORTH OF THE FRONT...POINTING INTO NORTHEAST IA/SOUTHWEST WI. WARM LAYER CLOUD DEPTH REACHES ABOUT 3500 FT WITH PW/S UP TO 1.75...NEARLY 200 PERCENT OF NORMAL. PRETTY DECENT SETUP FOR HEAVY RAINS. ALSO...NEAR WEST TO EAST TRACK OF STORMS BRINGING A TRAINING STORM THREAT INTO THE EQUATION. FLASH GUIDANCE IS AROUND 3 INCHES/3 HOURS...AND CAN PROBABLY TAKE MOST OF THE RAIN. HOWEVER...DEPENDING ON THE RAINFALL RATE...CAN/T RULE OUT THE POTENTIAL FOR LOCALIZED OR FLASH FLOODING. THE SHORTWAVE TROUGH EXITS EAST WED EVENING...ALLOWING FOR SOME WEAK RIDGING AND A SFC HIGH TO BUILD IN OVERNIGHT AND FOR THU. LOOK FOR A SHORT BREAK FROM THE PCPN CHANCES...WITH A FAIRLY PLEASANT AND SEASONABLE DAY ON TAP FOR THURSDAY. ON FRIDAY ANOTHER UPPER LEVEL SHORTWAVE TROUGH WILL BE SKIRTING EAST ALONG THE ND/CANADIAN BORDER...WITH A SFC COLD FRONT TRAILING FROM THE TROUGH SOUTHWARD INTO IA. DECENT PUSH OF MOISTURE OUT AHEAD OF THE FRONT...VIA LOW LEVEL MOISTURE TRANSPORT...WITH AN AXIS OF HIGHER THETA-E AIR TO PLAY WITH. 01.12Z GFS AND NAM PRETTY SIMILAR HERE...EXPECT FOR THE NAM DEVELOPING A CONVECTIVE COMPLEX OVER SD THU NIGHT. IT THEN TAKES THE MCV EAST/SOUTHEAST...AND FOCUSES MORE OF THE LOW LEVEL JET/MOISTURE TRANSPORT INTO THIS FEATURE...ALONG WITH THE BULK OF THE ITS QPF. THE GFS DOESN/T HAVE THIS FEATURE...AND THEREFORE ALLOWS FOR MORE CONVECTION ALONG THE FRONT...WITH A BIT MORE QPF FARTHER NORTH. A SIGNIFICANT DIFFERENCE FOR WHERE HEAVIER RAINFALL COULD OCCUR...PLUS IMPLICATIONS IN ANY SEVERE THREAT. HOWEVER...BOTH DO CONCUR THAT THE PCPN THREAT FOR FRI IS INCREASING. A BIT MORE INSTABILTY IN THE GFS SOLUTION...AND BOTH MODELS POINT TO A DECENT AMOUNT OF SHEAR. SO...DEPENDING ON IT SYSTEM/S EVOLUTION...THERE COULD BE A SEVERE RISK. .LONG TERM...FRIDAY NIGHT THROUGH TUESDAY GFS AND ECMWF STILL HOLDING ONTO A ZONAL UPPER LEVEL FLOW THROUGH THE EARLY PART OF NEXT WEEK...BUT ARE SHOWING SIGNS OF BUILDING A RIDGE ACROSS THE WESTERN U.S...WITH A RESULTING TROUGH OVER THE EASTERN 1/2 BY MID WEEK. MODELS STILL HAVING A HARD TIME WITH TIME/PLACEMENT OF THE VARIOUS SHORTWAVES PROGGED TO MOVE THROUGH THE ACTIVE FLOW...ALONG WITH THE POTENTIAL PHASE CHANGE TOWARD THE END OF NEXT WEEK. WHILE THE SPECIFICS VARY...BOTH THE GFS AND EC BRING SOME SHORTWAVE ENERGY ACROSS THE AREA FOR FRI-SUN TIME FRAME...WITH RESULTING PCPN CHANCES. AFTER A BRIEF BREAK...ANOTHER SHORTWAVE TROUGH COULD DROP ACROSS THE NORTHERN PLAINS INTO THE REGION ON TUES...AS THE RIDGE BUILDS TO THE WEST. YET ANOTHER SHOT FOR PCPN WITH THIS FEATURE. AGAIN THOUGH...CONFIDENCE REMAINS LOW ON THE TIMING/PLACEMENT OF THE VARIOUS PERTURBATIONS...AND WILL LEAN ON HPC GUIDANCE FOR PCPN CHANCES. TEMPERATURES LOOK TO STAY AT OR BELOW THE SEASONABLE NORMALS FOR THE WEEKEND INTO MID NEXT WEEK. && .AVIATION... AN AREA OF SHOWERS AND THUNDERSTORMS WILL MOVE EAST THIS AFTERNOON THROUGH SOUTHEAST MINNESOTA AND PARTS OF WEST CENTRAL WISCONSIN AND THEN TURN SOUTHEAST INTO NORTHEAST IOWA AND SOUTHWEST WISCONSIN. THESE THUNDERSTORMS MAY AFFECT KRST BETWEEN 01.20Z AND 02.00Z. A FEW OF THESE THUNDERSTORMS MAY BECOME SEVERE...WITH THE PRIMARY THREATS BEING DAMAGING WINDS AND LARGE HAIL. THERE ARE STILL QUITE A FEW QUESTIONS ON WHETHER THESE THUNDERSTORMS WILL AFFECT KLSE OR NOT. AS A COLD FRONT MOVES SOUTHEAST INTO THE AREA TONIGHT...ANOTHER LINE OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO MOVE SOUTHEAST THROUGH THE REGION. SINCE IT IS A BIT UNCLEAR WHETHER THUNDERSTORMS WILL AFFECT EITHER TAF SITE...JUST WENT WITH SHOWERS FOR NOW THROUGH 02.06Z. ADDITIONAL SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE ON WEDNESDAY. HOWEVER TIMING IS VERY UNCERTAIN...SO THEY WERE NOT ADDED TO THE TAFS. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...NONE. MN...NONE. IA...NONE. && SHORT/LONG TERM... RIECK AVIATION.......... BOYNE
