The episode as NWS ARX wrote it up.
Outflow from thunderstorms produced damaging winds in parts of southeast Minnesota in the late morning hours of June 11th. The automated weather observing system at the Preston airport reported a wind gust of 45 miles per hour in the late morning hours.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 330 AM CDT FRI JUN 11 2010 .SHORT TERM...THROUGH SUNDAY SURFACE ANALYSIS THIS MORNING SHOWS AN AREA OF LOW PRESSURE OVER SOUTHEAST COLORADO WITH A WARM FRONT NORTHEAST INTO CENTRAL IOWA AND THEN EAST/SOUTHEAST INTO CENTRAL ILLINOIS. LOCAL AND REGIONAL RADARS SHOWING SOME SCATTERED ACTIVITY FROM SOUTH CENTRAL WISCONSIN NORTHEAST TOWARD THE TWIN CITIES WHICH CONTINUES WEST TO A MCS COMING OUT OF SOUTH DAKOTA AND NEBRASKA. THE FOCUS FOR TODAY IS ON WHERE THE MORNING MCS WILL TRACK. SEVERAL OF THE SHORT RANGE MODELS...INCLUDING THE 11.03Z ARXWRF...11.00Z EASTARW AND SPCWRF...SEEM TO HAVE A DECENT HANDLE ON THE MCS. ALL THESE MODELS ESSENTIALLY CONTINUE IT ON AN EAST TO NORTHEAST TRACK TO ABOUT THE MINNESOTA/WISCONSIN BORDER BEFORE TURNING IT TO THE EAST/SOUTHEAST. THIS TRACK LINES UP WELL WITH THE CORFIDI VECTORS AND MCS MAINTENANCE PROBABILITIES FROM THE 11.06Z RUC. STILL A LITTLE BIT OF DOUBT ON EXACTLY HOW FAR SOUTH INTO THE FORECAST AREA THIS WILL EXTEND AND FOR NOW HAVE PLACED CATEGORICAL RAIN CHANCES FROM FLOYD COUNTY NORTHEAST TO ADAMS COUNTY. WHAT THEN OCCURS FOR THE AFTERNOON WILL LARGELY DEPEND ON THE PLACEMENT OF THE WARM FRONT AND HOW MUCH CLEARING CAN OCCUR BEHIND THE MCS. BOTH THE 11.00Z NAM AND GFS SUGGEST A BOUNDARY OF SOME KIND WILL BE LAYING SOUTHWEST TO NORTHEAST ACROSS THE FORECAST AREA. NOT SURE IF THIS WILL BE THE TRUE WARM FRONT OR THE TROUGH OF LOW PRESSURE CURRENTLY ACROSS THE DAKOTAS. THERE APPEARS TO BE A SIGNAL IN THE NAM AND SPCWRF OF A RENEWED MOISTURE TRANSPORT INTO THIS BOUNDARY SPARKING ANOTHER ROUND OF CONVECTION ACROSS SOUTHERN MINNESOTA INTO NORTHERN IOWA THAT THEN MOVES OFF TO THE EAST. MEANWHILE THE EASTARW DOES NOT SHOW THIS OCCURRING AND ONLY HAS SCATTERED CONVECTION ALONG THE BOUNDARY. IF SOME RECOVERY CAN OCCUR BEHIND THE MORNING MCS...THE NAM INDICATES BETWEEN 1000 AND 2000 J/KG OF ML CAPE WILL BE AVAILABLE ALONG AND SOUTH OF THE BOUNDARY ALONG WITH 25 TO 30 KNOTS OF 0-3KM SHEAR TO POSE A POSSIBLE WIND AND HAIL THREAT. AFTER TODAY...THE CONFIDENCE IN THE FORECAST DETAILS REALLY GOES DOWN HILL QUITE FAST. THE SOUTHWEST FLOW ALOFT IS EXPECTED TO CONTINUE INTO SUNDAY WITH PLENTY OF SHORT WAVE TROUGHS EMBEDDED IN THE FLOW. THE FRONT IS ALSO STILL EXPECTED TO BE LAYING ACROSS THE FORECAST AREA BUT ITS EXACT LOCATION WILL VARY DEPENDING ON HOW MUCH CONVECTION DEVELOPS ALONG THE FRONT AND WHERE THIS CONVECTION MOVES THE FRONT. MODELS HAVE A VERY DIFFICULT TIME IN THESE SCENARIOS AND HAVE THUS KEPT THE RAIN CHANCES IN THE 40 TO 50 PERCENT RANGE LETTING EACH SHIFT ADJUST THE VERY NEAR TERM WHEN IT BECOMES CLEAR WHERE THE CONVECTION WILL FORM. THERE DOES APPEAR TO BE A CONSISTENT SIGNAL THAT A NORTHERN STREAM SHORT WAVE TROUGH WILL START TO AFFECT THE UPPER MIDWEST SUNDAY AFTERNOON TURNING THE FLOW TO THE WEST/NORTHWEST ALLOWING THE FRONT TO A PUSH TO THE EAST AND HAVE STARTED TO LOWER THE RAIN CHANCES. .LONG TERM...SUNDAY NIGHT THROUGH THURSDAY THE 11.00Z ECMWF ALSO SHOWS THE TREND OF THE FRONT PUSHING EAST OF THE AREA SUNDAY WITH HIGH PRESSURE ALONG THE CANADIAN BORDER. IN AGREEMENT WITH SURROUNDING OFFICES REMOVED THE RAIN CHANCES FOR SUNDAY NIGHT. THE FRONT IS NOT EXPECTED TO GET VERY FAR EAST OF THE AREA BEFORE THE NORTHERN STREAM SHORT TROUGH STARTS TO SLOWLY MOVE EAST PUSHING A WEAK AREA OF LOW PRESSURE UP THE FRONT. THE HIGH WILL SLIP EAST INTO THE GREAT LAKES SETTING UP A DRY EAST TO SOUTHEAST FLOW. THE ECMWF SUGGESTS THIS WILL LARGELY HOLD THE NEXT ROUND OF RAIN TO THE SOUTHWEST HALF OF THE AREA MONDAY BEFORE IT SPREADS OVER THE AREA MONDAY NIGHT. WITH ONLY 20 TO 30 PERCENT RAIN CHANCES IN THOSE PERIODS DID NOT ATTEMPT TO MAKE ANY ADJUSTMENTS YET. && .AVIATION... CONFIDENCE REMAINS LOW ON THE EVOLUTION OF SHOWERS AND THUNDERSTORMS ACROSS THE PLAINS INTO THE TAF SITES THROUGH TONIGHT...ESPECIALLY BEYOND THE FIRST SIX HOURS OF THE FORECAST. PRESENTLY...A WARM AND HUMID AIRMASS IS LIFTING NORTH FROM THE CENTRAL PLAINS TO THE TAF SITES...WHICH HAS ALLOWED THE CEILINGS OF THE STRATUS TO LOWER. BOTH SITES SHOULD EXPERIENCE MVFR CEILINGS THIS MORNING...THEN IMPROVE TO VFR DURING THE AFTERNOON WITH DAYTIME MIXING. CEILINGS MAY FALL AGAIN TO MVFR TONIGHT...AIDED BY A NORTHWEST TO SOUTHEAST COLD FRONTAL PASSAGE AND EXPECTED PRECIPITATION ACTIVITY ALONG AND BEHIND THE FRONT. VISIBILITY FORECAST IS GENERALLY MVFR OR VFR...WITH THE MVFR RESTRICTED TO KRST WHERE A HIGHER PROBABILITY EXISTS DUE TO THE HUMID AIR MOVING IN AND HIGHER ELEVATION. REGARDING THE AFOREMENTIONED UNCERTAIN PRECIPITATION FORECAST...PLAN IS FOR THE CURRENT SCATTERED SHOWERS AND FEW EMBEDDED THUNDERSTORMS TO LIFT NORTH THIS MORNING. MAINTAINED VCSH WITH CB MENTIONS FOR THIS ACTIVITY. ANOTHER LARGER AREA OF SHOWERS AND STORMS OVER NEBRASKA AND EASTERN SOUTH DAKOTA SHOULD TRACK EAST OR PERHAPS EAST-SOUTHEAST...IMPACTING THE TAF SITES LATER THIS MORNING. IT DOES APPEAR WEAKENING IS POSSIBLE...SO DID NOT INCLUDE A CB AFTER 15Z. VCSH REMAINS UNTIL TIMING CAN BE PINNED DOWN. A WARM FRONT OR OUTFLOW FROM THE LATE MORNING STORMS SHOULD BE IN THE AREA DURING THE AFTERNOON. ASSUMING ENOUGH SUNSHINE OCCURS...COULD SEE MORE STORMS FIRE ON THESE BOUNDARIES IN THE LATE AFTERNOON THROUGH THE EVENING. ALTERNATIVELY...STORMS COULD FIRE TONIGHT ON THE COLD FRONT MOVING IN FOR TONIGHT. THEREFORE...VCSH WITH CB IS INCLUDED FOR THE LATE AFTERNOON INTO THE NIGHT. && .ARX WATCHES/WARNINGS/ADVISORIES...

SOUTHEAST MINNESOTA AND SOUTHWEST INTO CENTRAL WISCONSIN. .DAY ONE...TODAY AND TONIGHT SCATTERED THUNDERSTORMS ARE EXPECTED ACROSS THE AREA TODAY THROUGH TONIGHT AS A WAVE OF LOW PRESSURE TRACKS FROM SOUTHERN MINNESOTA INTO CENTRAL WISCONSIN. THE AMOUNT OF INSTABILITY AVAILABLE WILL BE IN QUESTION TODAY AS AN ONGOING COMPLEX OF SHOWERS AND EMBEDDED THUNDERSTORMS MOVES THROUGH THE AREA. IF ENOUGH CLEARING TAKES PLACE BEHIND THIS COMPLEX DURING THE AFTERNOON...THEN INCREASING INSTABILITY COULD PRODUCE THE THREAT OF SEVERE THUNDERSTORMS. THE MAIN THREAT WOULD INITIALLY BE FOR THOSE IN SOUTHEAST MINNESOTA AND NORTHEAST IOWA AFTER 2 PM...SHIFTING EAST INTO WESTERN WISCONSIN LATER IN THE AFTERNOON INTO THE EVENING. LARGE HAIL AND DAMAGING WINDS ARE THE MAIN THREATS. AN ISOLATED TORNADO CANNOT BE RULED OUT. IN ADDITION...HEAVY RAINFALL IS ALSO POSSIBLE WITH THESE STORMS WITH SOME LOCALIZED FLOODING. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY THUNDERSTORM CHANCES WILL CONTINUE THROUGH SATURDAY AS A COLD FRONT SLOWLY SAGS SOUTHEAST THROUGH THE AREA. RIGHT NOW IT APPEARS THE BEST CHANCE FOR ANY SEVERE WEATHER WILL BE SOUTH OF THE AREA. THUNDERSTORM CHANCES WILL RETURN TO THE AREA MONDAY AND LAST THROUGH THURSDAY AS SEVERAL DISTURBANCES APPROACH THE AREA FROM THE PLAINS. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NECESSARY THIS AFTERNOON THROUGH THIS EVENING. SPOTTERS ARE URGED TO STAY TUNED FOR THE LATEST INFORMATION PERTAINING TO THE SEVERE THREAT. .EMERGENCY MANAGEMENT COORDINATION... NO CALL IS SCHEDULED. DAS
