What was reported inside it

Time	Report	Where	Remark
Jul 17, 11:06 AM CDT	HAIL 0.88	1 W Hartland, MN	50 MPH WINDS WERE ALSO MEASURED AT THIS LOCATION.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Minneapolis, MN (KMPX), launched 12:00Z, 3.7 hours before the alert went out and 126 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION...UPDATED

.UPDATE...

UPDATED FOR 12Z AVIATION DISCUSSION BELOW.

&&

.DISCUSSION...
/ISSUED AT 341 AM CDT THU JUL 17 2008/

PATTERN A LITTLE TRICKY IN TERMS OF SPEED OF FEATURES. EARLIER IN
THE SHIFT...THOUGHT THAT THE GFS MIGHT BE A LITTLE FAST...ALTHOUGH
THE POSITION AND STRENGTH OF THE SFC LOW OVER SD WAS CLOSE TO THE
GFS AND SREF. THE CLUSTER OF STORMS MOVING THROUGH SW MN DRIVEN
BY SOME MID LEVEL WARM ADVECTION WITH AND EAST WEST HOT PROD
POINTED SOMEWHAT AT SE MN. AXIS OF HIGHER ML CAPE ALSO IN PLACE
ACROSS SOUTH CENTRAL MN. NEXT CLUSTER OF STORMS OVER CENTRAL SD
TRUCKING EAST AT A DECENT CLIP...AND DOES SEEM TO MATCH A MID
LEVEL WARM ADVECTION MAX ON THE GFS TRACKING FROM NW SD INTO T
EAST CENTRAL SD AT BY 12Z. THIS WOULD SUGGEST THAT SHOWERS AND
THUNDERSTORMS COULD BE MAINLY THIS MORNING AND EARLY AFTERNOON OVER
CENTRAL MN. 850 MB MOISTURE TRANSPORT MORE ROBUST ON THE NAM AND
SREF...ESPECIALLY OVER SE MN LATE THIS AFTERNOON AND EVENING. THE
GFS MAX GENERALLY IN THE SAME AREA BUT OF COURSE MOVING THROUGH
FASTER. HAVE ENDED THE PRECIP EARLIER OVER MUCH OF CENTRAL MN THIS
EVENING AND THEN TRIMMED AT A SLOWER PACE FARTHER SOUTH. WITH THE
POSSIBILITY OF A FASTER MOVEMENT ON STORMS AND BETTER MOISTURE
TRANSPORT JUST TO OUR SE...WILL KEEP WITH JUST THE HEAVY RAIN
WORDING AND NOT ISSUE ANY FFA AT THIS TIME. THANKS FOR COORD WITH
ARX..GRB..DLH.

LOOKS LIKE THERE WILL BE A BREAK IN THE RAIN CHANCES FOR MUCH OF
FRIDAY...EXCEPT THE FAR S OR SE...WITH A DECENT PUSH OF NW FLOW. NAM
IS ACTUALLY DRIER THAN THE GFS FOR THIS PERIOD. THIS IDEA OF A
BREAK ON FRIDAY WAS ACTUALLY HINTED AT SEVERAL DAYS AGO BY THE
MODELS. THE FRONT DOES WORK BACK NORTH FOR THE WEEKEND THOUGH.

&&

.AVIATION.../12Z TAF ISSUANCE/

YET ANOTHER TRICKY SET OF TAFS...WITH QUASI STNRY FNT REMAINING
ACRS THE AREA. SOME MDL DIFFERENCES ON HANDLING OF
FNT/CONVECTION...BUT GFS HANDLING CURRENT ACTIVITY BEST. SO WILL
FAVOR A FASTER MOVEMENT OF FNT ONCE IT ACTUALLY GETS MOVG SWRD.
TSTM COMPLEX IN ERN SODAK SHUD MOV EWRD...AFFECTING ALL THE TAF
SITES THIS MRNG. DIST SPD TOOL BRINGS IT INTO RWF BY 13Z...STC BY
14Z...MSP BY 15Z...RNH BY 16Z...AND EAU BY 17Z. AXN SHUD MISS OUT
ON THE THUNDER...BUT COULD SEE SOME RA. HAVE LEFT IT OUT
ATTM...HOWEVER. THINKING IS THAT THIS MRNG CONVECTION COULD REDUCE
THE AREAL COVG OF TSRA THIS AFTN/EVE. WITH GFS SINKING FNT INTO
SRN MN/WRN WI BY THIS EVE...ELECTED TO ONLY MENTION TSRA CHCS AT
RWF/MSP/RNH/EAU. LINGERED SHRA ACTIVITY AT EAU FROM 05Z UNTIL THE
END OF THE VALID TAF PD...WITH S/WVS RIDING UP THE FNT...ALTHO IT
MAY END QUICKER THAN THAT. LATER ISSUANCES CAN ADDRESS THIS. WINDS
WL BE TRICKY...ESPECIALLY WITH FNTL MOVEMENT IN QUESTION. FAVORED
SRLY WINDS TRANSITIONING TO WRLY AND FINALLY NWRLY LATE AT ALL
SITES EXCEPT AXN...WHICH IS N OF THE FNT ATTM.
