What happened

The episode as NWS MPX wrote it up.

During the afternoon, a larger complex of storms developed across western Minnesota, and moved quickly across portions of central and southern Minnesota during the evening. Damage was extensive as several bow echoes, supercells, and squall lines raced across the area. There were numerous reports of structural damage to farms and homesteads, very large hail, and very large trees blown down. Softball to baseball size hail was reported near New Ulm, Minnesota, with several reports of wind damage throughout southern, and east-central Minnesota.

Several significant tornadoes occurred in portions of south central Minnesota during the late afternoon, and early evening hours.

Two separate severe storms moved across the Twin Cities area, one produced minor damage with hail in the late afternoon, but the second that occurred in the early evening caused more straight-line wind damage throughout the area, along with flash flooding.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
620 AM CDT FRI JUN 25 2010

UPDATED TO ADD THE 12Z AVIATION DISCUSSION BELOW...
.DISCUSSION...

A SEVERE WEATHER EVENT IS EXPECTED TO UNFOLD LATER TODAY ACROSS
MUCH OF THE FORECAST AREA...AS A SURFACE BOUNDARY SETS UP OVER
SOUTHERN MN. ADDITIONALLY...IT COULD BE A ONE-TWO PUNCH OF SEVERE
WEATHER OVER THE NEXT 48 HOURS...AS THE AFOREMENTIONED BOUNDARY
LINGERS ACROSS THE CWA ON SATURDAY.

EARLY MORNING WATER VAPOR IMAGERY SHOWS A COLLECTION OF MID LEVEL
IMPULSES DROPPING FROM SOUTHERN SASKATCHEWAN/MANITOBA INTO
NORTHERN MN. ASSOCIATED CONVECTION CONTINUES TO SPAWN OVER NORTH
DAKOTA AND NORTHERN MN OVERNIGHT...ON THE NOSE OF DECENT 850-700MB
MOISTURE TRANSPORT. WHILE ISOLD-SCT SHOWERS/TS ARE EXPECTED TO
GRADUALLY SPREAD INTO THE CENTRAL MN PORTION OF THE CWA THIS
MORNING...THE MORE WIDESPREAD AND POTENTIALLY SEVERE ACTIVITY IS
EXPECTED TO ARRIVE THIS AFTERNOON/EVE AS DESTABILIZATION OCCURS IN
THE VICINITY OF THE BOUNDARY OVER SOUTHERN MN. SUPERCELLULAR STORM
MODE APPEARS PROBABLE THIS AFTERNOON/EVE FROM CENTRAL INTO SOUTH
CENTRAL MN WITH PROGGED 0-6KM BULK SHEAR VALUES OF 50-60 KTS.
FORECAST ML CAPE TO 3 KM OF 100 J/KG AND 0-1KM EHI VALUES OF 2-4
MS/S2 ALSO ILLUSTRATE THE POTENTIAL FOR TORNADOGENESIS OVER
CENTRAL/SOUTH CENTRAL MN THIS AFTN/EVE. EXPECT THE STORM
MODE/THREATS TO TRANSITION TO A MCS/DAMAGING WIND SCENARIO AS THE
EVENING PROGRESSES. HEAVY RAINFALL WILL BECOME A CONCERN LATER THIS
EVENING AND TONIGHT...AS AN AREA OF DIFFLUENT THICKNESS SETS UP FROM
CENTRAL MN INTO WEST CENTRAL WI...WHERE PWAT VALUES SURGE TO NEARLY
200 PERCENT OF NORMAL /2 INCHES/. HAVE RELEGATED 90 POPS AND 1-2
INCH QPF VALUES OVER THIS AREA OF CENTRAL MN AND WEST CENTRAL WI FOR
TONIGHT.

FORECAST CONFIDENCE WAS INITIALLY WAVERING A BIT FOR
SATURDAY...DUE IN PART TO THE 25.00Z RUN OF THE NAM...WHICH PUSHED
THE BOUNDARY AND IMPETUS FOR SEVERE STORMS SOUTH OF THE FORECAST
AREA. HOWEVER...THE 25.06Z RUN OF THE NAM HAS COME BACK IN LINE
WITH THE MAJORITY OF THE DETERMINISTIC AND ENSEMBLE MEAN
SOLUTIONS...INCLUDING THE 25.00Z ECMWF...WHICH KEEP THE FRONT
SITUATED OVER CNTRL/SRN MN INTO WEST CENTRAL WI ON SATURDAY
AFTERNOON. HAVE THEREFORE INCLUDED 70-80 POPS ACROSS THE MAJORITY
OF THE CWA ON SATURDAY AFTN/NIGHT. THE FEATURE THAT THE SATURDAY
EVENT WOULD HAVE GOING FOR IT THAT TODAY/S EVENT DOESN/T...IS THE
ENTRANCE REGION OF A 100 KT JET IN PLACE OVERHEAD.

SUNDAY SHOULD WIND UP BEING A MOSTLY DRY DAY...OTHER THAN POSSIBLY
A FEW LINGERING SHOWERS IN THE MORNING ACROSS EAST CENTRAL MN AND
WEST CENTRAL WI.

A RIDGE OF HIGH PRESSURE BUILDS ACROSS THE AREA THROUGH AT LEAST
THE MIDDLE OF NEXT WEEK...WHICH WILL BRING DRY AND MILD CONDITIONS
TO CLOSE OUT THE MONTH OF JUNE.

.AVIATION... /12Z TAF ISSUANCE/

COVECTIVE COMPLEX OVER NORTH CENTRAL MN...WILL CONTINUE TO WEAKEN AS
IT MOVES INTO A MORE STABLE AIRMASS THIS MORNING. ON THE SOUTHERN
END OF THE COMPLEX...EXPECT A FEW THUNDERSTORMS MAY DEVELOP AS FAR
SOUTH NEAR KAXN AND KSTC. ELSEWHERE...MID/UPPER LEVEL IMPLUSES...ARE
EXPECTED TO TRIGGER THUNDERSTORMS OVER THE UPPER MIDWEST THIS
AFTERNOON AND EVENING. FRONTAL BOUNDARY IS FORECAST TO PUSH
SOUTH-EAST OVER SOUTHERN MINNESOTA TONIGHT...THEN BECOME
QUASI-STATIONARY. AIRMASS EXPECTED TO DESTABLIZE OVER A VAST PART OF
THE CENTRAL AND SOUTH CENTRAL MN AND WESTERN WISCONSIN LATER THIS
AFTERNOON. IMPLUSE OVER SOUTH DAKOTA...SHOULD HELP FIRE OFF SOME
INTENSE STORMS LATER...WEATHER CONDS LOWERING TO MVFR TO IFR CONDS
IN THE VICINITY OF THE STORMS. MAINLY VFR CONDS THROUGH THE BULK OF
THE DAY.  WEATHER CONDITIONS LOWERING OVERNIGHT TO MVFR-IFR CATEGORY
IN LOW CLOUDS AND FOG.

KMSP...VFR CONDS CONTINUES THRU MID AFTERNOON.  WEATHER CONDS WILL
LOWER TO MVFR/IFR CATEGORY LATE AFTERNOON AND EVENING AS CONVECTION
INITIATES. SOME IMPROVEMENT OVERNIGHT..THEN CLOUDS/CEILING LOWERING
TO UNDER 2000 FEET AGL AND VISIBILITY 3-5 MILES IN FOG. SFC WINDS
SOUTH-SOUTHWEST 10-20 MPH...BECOMING NORTHERLY AFTER FRONTAL
PASSAGE.
