What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Twin Cities, MN wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 26, 10:39 PM CDT, 1 minute earlier.

Area forecast discussion, Jun 26, 10:39 PM CDT, 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
1039 PM CDT SAT JUN 26 2010

.DISCUSSION...

WARM FRONT BECOMING WELL DEFINED VCNTY MN/I BORDER WITH AROUND
5000 J/KG ML CAPE SE SD INTO NW IA. VERY LITTLE CIN OVER THIS AREA
AS WELL. STRONG...MAINLY ELEVATED CELLS CONTINUE TO MOVE TOWARD SW
MN. CURRENT 850-300 /EW AND SLIGHTLY ESE/ THICKNESS FIELD
SUGGESTS THE STRONGEST STORMS INITIALLY MOVING ACROSS SOUTH
CENTRAL MN. MORE UPSCALE DEVELOPMENT QUITE POSSIBLE LATER AS THE
UPPER TROUGH APPROACHES ALONG WITH DEVELOPING LARGE SCALE UPPER
DIV. THE UPPER DIV IS FORECAST TO MAXIMIZE LATER TONIGHT. THE LOW
LEVEL/850 MB MOISTURE TRANSPORT IS FORECAST BY BOTH THE GFS AND
NAM TO DECELERATE OVER SE MN AND CENTRAL WI LATER TONIGHT. THERE
IS SOME UNCERTAINTY ABOUT THE HEAVIER RAIN AXIS DEPENDING ON THE
OUTFLOWS THIS EVENING...BUT GIVEN THAT CORE METRO PROBLEMS AND A
HEAVIER RAIN AXIS THAT OCCURRED INTO WI LAST NIGHT...HAVE EXPANDED
THE FFA A LITTLE FARTHER ENE.

STILL DECENT CONSISTENCY WITH THE TROUGH TO MOVE OUT SUNDAY
MORNING...BUT SOME CHANCE THAT WEAK VORT MAY AID SOME DEVELOPMENT
OF ISOLD CELLS NE AREAS SUNDAY EVENING. THE GFS IS THE MOST
AGGRESSIVE WITH BRINGING A SHORT WAVE INTO THE UPPER RIDGE LATE TIN
THE WEEK. WILL KEEP THINGS DRY UNTIL FRIDAY NIGHT AND
SATURDAY...AND THEN INTRODUCE A CHANCE. IS SUSPECT THAT MUCH OVER
A WEEK OF NO PRECIP IS HARD TO COME BY THIS TIME OF YEAR. THE
RIDGE SEEMS TO BE STRONG ENOUGH ALONG WITH THE SAME DRY SIGNALS
FROM THE NAEFS AND GEFS TO KEEP THE DRY FORECAST INTO FRIDAY.
WE SHOULD GET A COUPLE OF DAYS OF COOLER TEMPS AFTER THIS TROUGH
PASSAGE AND THEN GRAVITATE BACK TO NEAR NORMAL OR SLIGHTLY ABOVE BY
THE END OF THE WEEK.

&&

.AVIATION... /06Z TAF ISSUANCE/

JUST BEFORE MIDNIGHT...THE SFC TROUGH WAS ON THE WESTERN FRINGES OF
WEST CENTRAL MN...AND SHOULD CONTINUE TO MOVE EAST ACROSS THE
FORECAST AREA OVERNIGHT AND SUNDAY MORNING. LIFR TO IFR CONDS
PERSISTING OVER WEST CENTRAL WISCONSIN DURING THE OVERNIGHT
HOURS...CONDS EXPECTED TO IMPROVE FROM WEST TO EAST. WEAK SURFACE
RIDGE BUILDING BEHIND THE SFC TROUGH. WINDS VARIABLE IN DIRECTION IN
THE VICINITY OF THE TSRA. WINDS BECOMING WEST-NORTHWEST 10 TO 15
MPH. CLOUD/CEILING HEIGHTS LIFTING TO 4000-5000 FEET AGL SUNDAY.

KMSP...WEATHER CONDITIONS WILL CONTINUE TO IMPROVE AS A SURFACE
TROUGH MOVING THROUGH BY MID SUNDAY MORNING. IN THE
MEANTIME...EXPECT SOME MARGINAL TO IFR WEATHER CONDS IN THE VICINITY
OF THUNDERSTORMS.  WINDS VARIABLE IN DIRECTION IN THE VICINITY OF
THE TSRA. WINDS BECOMING WEST-NORTHWEST 10 TO 15 MPH. CLOUD/CEILING
