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, 11.3 hours before the alert went out and 139 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.

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 Jul 7, 4:38 PM CDT, 1 hour 37 minutes earlier.

Area forecast discussion, Jul 7, 4:38 PM CDT, 1 hour 37 minutes before

AREA FORECAST DISCUSSION...UPDATED TO ISSUE 00Z AVIATION DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
438 PM CDT MON JUL 7 2008

.DISCUSSION...

MUCH LESS AMPLIFIED PATTERN...RELATIVE TO RECENT WEEKS...WILL TAKE
OVER FOR MUCH OF THE FORECAST PERIOD. THAT SAID THERE WILL STILL BE
PERIODIC BUCKLES IN THE UPPER FLOW AS UPPER TROUGHS TRAVERSE THE
GENERALLY ZONAL FLOW. AS A RESULT THE WEATHER FOR THE WEEK REMAINS
FAIRLY ACTIVE. EARLY AFTERNOON WATER VAPOR IMAGERY SHOWS FAIRLY
SHARP TROUGH MOVING ACROSS THE EASTERN DAKOTAS/WESTERN MINNESOTA.
FURTHER UPSTREAM...FLAT FLOW EXISTS WITH AN EXPANSIVE AREA OF OF
UPPER LEVEL ANTICYCLONIC FLOW OVER THE PACIFIC WEST OF THE
CALIFORNIA COAST. AN UPPER LEVEL LOW CONTINUES TO SPIN SOUTH OF THE
ALEUTIANS WITH FAST WESTERLY FLOW FEEDING INTO BRITISH COLUMBIA.

LOOKING AT SOME DETAILS...

THREE AREAS OF STORMS ONGOING LATE THIS AFTERNOON AND WILL CONTINUE
INTO THIS EVENING IN ASSOCIATION WITH SEVERAL DIFFERENT FEATURES.
STATIONARY FRONTAL BOUNDARY EXTENDING ACROSS NORTHWEST WI THROUGH
SOUTH CENT WI CONTINUES TO HAVE STRONG CONVECTION FIRE ALONG IT.
NORTHERN EDGE OF INSTABILITY GRADIENT EXTENDS ACROSS FAR SOUTHEAST
MN AND INTO WESTERN WISCONSIN. ANOTHER AREA OF SHOWERS AND
THUNDERSTORMS IS JUST ENTERING WESTERN MN IN CONJUNCTION WITH A WEAK
SFC BOUNDARY AND AN UPPER LEVEL TROUGH AXIS. A BIT FURTHER WEST A
BETTER DEFINED COOL FRONT IS CROSSING CENTRAL NORTH DAKOTA WITH
ANOTHER SHORTWAVE MOVING INTO MANITOBA. SHOWERS AND THUNDERSTORMS
HAVE ALSO FIRED IN THIS AREA. SHOWERS AND THUNDERSTORMS WILL
CONTINUE ACROSS WEST CENT WI EARLY THIS EVENING IN CONJUNCTION WITH
THE FIRST FRONT. ADDITIONAL SHOWERS AND THUNDERSTORMS WILL MARCH
ACROSS WESTERN AND CENTRAL MINNESOTA LATE THIS AFTERNOON AND EARLY
THIS EVENING WITH THE LATTER 2 BOUNDARIES/UPPER TROUGHS. SEVERE
POTENTIAL EXISTS WITH ALL OF THESE STORMS WITH THE MAIN THREAT BEING
DAMAGING WINDS AND LARGE HAIL. PRECIP SHOULD WIND DOWN ACROSS WEST
CENT MN BY MID EVENING AS DIURNAL HEATING IS LOST AND LAST TROUGH
CROSSES THE AREA. EXPECT THAT PRECIP WILL END AROUND MIDNIGHT ACROSS
EAST CENT MN WITH THINGS WINDING DOWN ACROSS WEST CENT WI AFTER
MIDNIGHT.

HIGH PRESSURE ARRIVES FOR TUESDAY WITH LOW AMPLITUDE WEST-NORTHWEST
FLOW DEVELOPING ALOFT WHICH CONTINUES INTO WEDNESDAY. THIS WILL KEEP
QUIET WEATHER IN PLACE. LAPSE RATES BECOME STEEP IN THE AFTERNOON AS
COLD AIR MOVES IN ALOFT WITH CONTINUED CYCLONIC FLOW. ATMOSPHERIC
COLUMN WILL BE PRETTY DRY HOWEVER SO WILL KEEP THE FORECAST DRY.
THERE COULD BE A SPRINKLE ACROSS THE NORTH IN THE MORNING WITH SOME
RESIDUAL MOISTURE LINGERING. MUCH LESS HUMID CONDITIONS WILL BE IN
PLACE AND TEMPERATURES WILL BE COOLER AS WELL WITH HIGHS IN THE MID
TO UPPER 70S NORTH AND AROUND 80 SOUTH.

THE PATTERN BECOMES MORE ACTIVE WEDNESDAY NIGHT INTO THURSDAY AS
HIGH PRESSURE SHIFTS TO THE EAST ALLOWING SOUTHERLY FLOW TO
INCREASE. LOW PRESSURE DEVELOPS TO THE WEST ACROSS THE HIGH PLAINS
WITH MID LEVEL WARM ADVECTION INTO WESTERN AND CENTRAL MINNESOTA
INTENSIFYING WEDNESDAY NIGHT WITH THETA-E ADVECTION INCREASING. WITH
MID LEVEL INSTABILITY...WARM ASCENT..AND MOISTURE TRANSPORT COMING
TOGETHER EXPECT THAT SHOWERS AND THUNDERSTORMS WILL BECOME POSSIBLE
LATE WEDNESDAY NIGHT ACROSS THE NORTHWEST CWA. AT THIS POINT IT
LOOKS MORE LIKELY FOR ACTIVITY TO DEVELOP TO THE WEST THEN MOVE INTO
THE WESTERN CWA THURSDAY MORNING. AS LOW PRESSURE BETTER ORGANIZES
THURSDAY A WARM FRONTAL BOUNDARY SETS UP FROM WEST TO EAST ACROSS
CENTRAL/NORTHERN MINNESOTA. FRONTAL POSITION WILL BE KEY IN
DETERMINING LOCATION OF THUNDER POTENTIAL THURSDAY AFTERNOON.
TRIGGER FOR STORMS OTHER THAN ALONG THE WARM FRONTAL BOUNDARY IS A
BIT INCOHERENT AT THIS TIME RANGE BUT PROBABILITY OF A SHORTWAVE
EMBEDDED IN THE ZONAL FLOW IS HIGH. PLENTY OF INSTABILITY IS
FORECAST SO STORMS WILL CERTAINLY BE POSSIBLE THURSDAY AFTERNOON.

AN APPROACHING UPPER TROUGH WILL PUSH THE SFC LOW OVER THE NORTHERN
PLAINS EASTWARD FRIDAY WHICH WILL DRAG A SHARP COLD FRONT ACROSS THE
DAKOTAS AND INTO WESTERN MINNESOTA FRIDAY AFTERNOON/EVENING. SHOWERS
AND THUNDERSTORMS ARE EXPECTED TO DEVELOP AHEAD OF THE FRONT WHERE
STRONG INSTABILITY IS FORECAST TO BE IN PLACE AS NOSE OF 100 KT
UPPER JET MOVES INTO CENTRAL/NORTHERN MINNESOTA. HOWEVER...ACTIVITY
MAY BE FOCUSED FURTHER NORTH ALONG THE FRONT AS CAPPING INVERSION
/H7 TEMPS OF 12 TO 14 C/ WILL BE IN PLACE OVER THE ENTIRE CWA.
ACTIVITY ACROSS THE CWA MAY BE HELD OFF UNTIL EVENING WHEN THE UPPER
TROUGH DRAWS CLOSER. THE MAIN CHALLENGE AT THIS STAGE WILL BE THE
TIMING OF THE SYSTEM WITH RUN TO RUN DISAGREEMENT EXHIBITED. FRONT
MAY SLOW DOWN A BIT AND TAKE UNTIL MIDDAY SATURDAY TO EXIT DELAYING
POPS FRIDAY EVENING AND KEEPING POPS IN SATURDAY MORNING. THERE HAS
BEEN BETTER SUPPORT FOR A SLOWER PROGRESSION THUS FAR SO WILL KEEP
SOME LOW POPS IN THE EAST SATURDAY MORNING. THE FRONT WILL STALL
AND BECOME ORIENTED FROM WEST TO EAST SATURDAY BUT THERE IS SOME
QUESTION ON HOW FAR SOUTH OF THE AREA THIS WILL OCCUR. LOW PRESSURE
WILL DEVELOP ACROSS KANSAS AND MOVE NORTHEASTWARD SATURDAY AND
SUNDAY. HAVE LOW POPS IN THE SOUTH SATURDAY NIGHT GIVEN THE
UNCERTAINTY OF THE FRONTAL POSITION BUT IT WILL PROBABLY NOT BE TOO
FAR FROM THE AREA. POPS EXPAND NORTHWARD SUNDAY AS THE LOW
APPROACHES BUT AGAIN THE TIMING IS UNCERTAIN SO IT IS POSSIBLE THAT
SEVERAL DRY PERIODS COULD OCCUR THROUGH THE WEEKEND AFTER THE FRONT
PASSES EARLY SATURDAY AND BEFORE IT WORKS BACK NORTHWARD SOMETIME
SUNDAY. BALMY CONDITIONS WILL BE IN PLACE FROM THURSDAY UNTIL THE
FRONT PASSES SATURDAY WITH HIGHS AROUND 90 WITH DEW POINTS AROUND 70
ARE EXPECTED WITH LITTLE RELIEF AT NIGHT ACROSS MOST AREAS WITH LOWS
IN THE UPPER 60S AND LOWER 70S. TEMPERATURES DO NOT LOOK TO COOL TOO
MUCH SATURDAY WITH M/U 80S STILL EXPECTED BUT SLIGHTLY DRIER AIR
SHOULD ARRIVE REDUCING THE STICKINESS OF THE AIR.  ..MDB..
