Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched 12 storm reports to this severe thunderstorm warning; the first came 0 minutes after it went out.

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

Area forecast discussion, Jun 30, 3:10 PM EDT, 30 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
310 PM EDT THU JUN 30 2011

...A FEW STORMS MAY BE STRONG TO ISOLD SEVERE REST OF THIS AFTN INTO
EARLY EVE...

...WARMER AND DRIER WEATHER ON TAP INTO WEEKEND...

.SYNOPSIS...
CONVECTION DEVELOPED DURING EARLY AFTN ACROSS STALLED FRONT ALONG
CNTRL FL PANHANDLE INTERACTING WITH WEAK SEA BREEZE AND SEVERAL
OUTFLOW BOUNDARIES AIDED BY H5 TROUGH...HIGH PWATS/DEW POINTS. UNDER
TEMPS UP TO THE MID 90S AND AMPLE DEEP LYR MOISTURE...MODERATE
AMOUNTS OF MLCAPE HELPED DEEPEN THESE CELLS AS THEY DRIFTED NWD
ALONG SEABREEZE WITH ACTIVITY FOCUSED FROM LEON COUNTY E/SE TO DIXIE
COUNTY. ADDITIONAL ISOLD CELLS DEVELOPED ACROSS AL/GA COUNTIES. WEAK
LOW/MID LEVEL FLOW WILL FAVOR BRIEF PULSE STORMS AND A FEW CAN
GENERATE GUSTY WINDS INTO THIS EVE. ALSO CANNOT DISCOUNT BRIEF
SEVERE STORM WITH MICROBURSTS AND DAMAGING WINDS. THERE WERE VARIOUS
REPORTS OF WATERSPOUTS THIS MORNING AND AFTERNOON IN THE VICINITY OF
APALACHICOLA.

AT UPPER LEVELS...
THE LARGE SCALE LONGWAVE PATTERN REMAINS HIGHLY AMPLIFIED. THIS IS
HIGHLIGHTED BY A TROUGH OVER WRN STATES WITH LOW OVER SRN UT...A
RIDGE FROM DESERT SW NEWD TO ANTICYCLONE OVER SW KS THEN NNE ACROSS
UPPER MIDWEST/UPPER MS VALLEY REGIONS...AND A TROUGH OVER ERN MOST
STATES FROM 562DM LOW OVER QUE AND AXIS SWD TO 588DM LOW SW OF
APALACHICOLA.

DURING THE NEXT 24HRS...WRN TROUGH IS FORECAST TO MOVE NEWD ACROSS
THE NRN AND CNTRL PLAINS WITH ASSOCD POTENT GREAT BASIN SHORTWAVE
EJECTS ENE. THIS WILL FLATTEN RIDGE AND IT SHUNTS IT FURTHER NEWD TO
UPR MS VALLEY/UPR GREAT LAKES. IN RESPONSE...DOWNSTREAM UPPER TROUGH
SHUNTED E/NE FROM OFF ERN SEABOARD SWWD TO NE MOST GULF OF MEX.
ASSOCD CLOSED QUE LOW EDGES SLOWLY E AND OPENING INTO A TROUGH. H5
TROUGH AXIS SHOULD PUSH SOUTH OF CWA TONIGHT. LOCALLY THIS WILL
YIELD A PREDOMINANT DRY NORTHERLY FLOW. TLH VAD SHOWS VEERING FLOW
FROM SW AT SFC TO NW AT 2K TO NNE ABOVE 6K. THIS ALSO REFLECTED IN
MODEL SOUNDINGS. I.E. GFS TAE WITH 1.93 INCH PWAT AT 18Z THU
DECREASING TO 1.21 INCH PWAT AT 18Z FRI. FARTHER INTO ENCROACHING
DRIER AIR...DHN WITH 1.46 INCH PWAT AT 18Z THU DECREASING TO 1.14
INCH PWAT AT 18Z FRI.

AT LOWER LEVELS...
THE SUBTROPICAL RIDGE EXTENDS WWD ACROSS S FL AND INTO THE GULF.
LOOKING N...A STALLED WEAK FRONTAL BOUNDARY WAS NOTED ALONG THE FL
COAST. MODELS IMPLY THAT FRONT WILL DRIFT SOUTH AND STALL ALONG THE
COAST INTO FRIDAY AS HIGH PRESSURE DEVELOPS OVER THE WV APPALACHIAN
MOUNTAINS. LOOKING SOUTH...THE RIDGE AXIS WILL DRIFT NORTH INTO
CENTRAL FLORIDA FRIDAY AND THEN INTO SOUTH GEORGIA ON SATURDAY. ALL
THIS WILL WASH OUT SURFACE FRONT/TROUGHS B4 SATURDAY.

TS ARLENE WAS MOVING OVER THE E COAST OF MEXICO.

&&

.SHORT TERM...TONIGHT THROUGH SUNDAY.
SHORT TERM WILL SHOWS INCREASINGLY DRIER AIRMASS...FEWER CLOUDS AND
SLIGHTLY WARMER HIGHS AND COOLER LOWS EACH DAY THRU WEEKEND.

TONIGHT...UNLIKE RECENT NIGHTS...CONVECTION OVER LAND IS EXPECTED TO
DISSIPATE FAIRLY EARLY...BUT WILL LAST LONGER OVER THE APALACHEE BAY
AND POSSIBLY DIXIE COUNTY. WILL GO WITH 30-10% SE-NW POP GRADIENT.
LOWS FROM AROUND 70 SE BIG BEND/ADJACENT GA TO MID 70S PANHANDLE
COAST.

FRIDAY...40-10% SE-NW POP GRADIENT DAYTIME...0 TO 20% N-S AT NIGHT.
HIGHS 90 COAST TO MID-UPPER 90S NORTH. LOWS NEAR 70 SE BIG
BEND/ADJACENT GA TO MID 70S PANHANDLE COAST.

SATURDAY...10-20% POPS DAYTIME...NIL POPS AT NIGHT. HIGHS 90 COAST
TO MID-UPPER 90S INLAND. LOWS UPPER 60S SE BIG BEND/ADJACENT GA
TO LOW 70S SE ALA/SW GA.

SUNDAY...NIL POPS. HIGHS 90S COAST TO UPPER 90S INLAND.

&&

.LONG TERM...SUN NIGHT THROUGH NEXT THU.
THE LONG TERM PERIOD BEGINS WITH RIDGING EXTENDING FROM SOUTHERN
CALIFORNIA EASTWARD TO THE TENNESSEE RIVER VALLEY. THERE IS A BREAK
BETWEEN THIS LARGE RIDGE AND THE BERMUDA RIDGE JUST OFF THE CAROLINA
COAST DUE TO A DEPARTING EAST COAST TROF. WITH THE RIDGING REMAINING
IN PLACE INTO AT LEAST MONDAY...POP CHANCES WILL REMAIN RELATIVELY
LOW AND CONFINED PRIMARILY TO THE SEA BREEZE ZONE IN THE AFTERNOON.
TEMPERATURES WILL RETURN TO NEAR THE 100 DEGREE MARK. RECORD HIGH
TEMPERATURES FOR TALLAHASSEE FOR THE FIRST PART OF JULY ARE IN THE
MID 100S (1931)...WHICH WITH THE EXPECTED PATTERN SHOULD BE SAFE.

BY TUESDAY...THE LARGE UPPER LOW OVER THE HUDSON BAY WILL DEEPEN AS
IT SURGES SOUTHEASTWARD INTO THE ST LAWRENCE RIVER VALLEY. THIS WILL
RESULT IN THE LARGE RIDGE RETREATING WESTWARD...WHILE THE EASTERN
COMPONENT WEAKENS CONSIDERABLY...CREATING A GAP BETWEEN THE WESTERN
CONUS RIDGE AND THE BERMUDA RIDGE. AS THIS OCCURS ON TUESDAY...AN
INCREASE IN MOISTURE IS EXPECTED TO ARRIVE FROM THE SOUTHERN GULF OF
MEXICO IN ASSOCIATION WITH A WESTWARD MOVING TROPICAL WAVE. RAIN
CHANCES WILL BE ON THE RISE AS DEEP LAYER MOISTURE INCREASES AS
WELL. MAX TEMPS WILL ALSO DROP OFF INTO THE MID 90S.

&&

.MARINE...
A TROUGH NEAR THE COAST WILL GRADUALLY SETTLE SWD ACROSS THE
WATERS WITH HIGH PRESSURE BECOMING ESTABLISHED TO THE N. THIS WILL
CREATED A PERIOD OF RATHER LIGHT WINDS WITH SEA BREEZE DOMINATING
THIS AFTERNOON INTO FRI WITH WINDS SWITCHING AROUND TO THE E BY SAT.
CONVECTIVE COVERAGE OVER THE WATERS WILL CONTINUE TO MAXIMIZE DURING
THE EARLY MORNING HOURS AND DROP OFF DURING THE MIDDAY TO AFTERNOON
HOURS. TS ARLENE WILL GENERATE SOME SWELLS WHICH WILL MOVE NEWD AND
LIKELY INCREASE RIP CURRENT RISK BY LATE WEEKEND.... ESPECIALLY OVER
PANHANDLE BEACHES.

&&

.AVIATION...
SCT-BKN CU FIELD HAS BECOME ESTABLISHED ACROSS MUCH OF THE REGION
EARLY THIS AFTERNOON. INTERESTING BAND THROUGH SOUTHERN AL INCLUDING
KDHN WITH A LACK OF CU...BUT EXPECT THIS AREA TO FILL IN WITH TIME.
THE CU FIELDS IS GIVING WAY TO A SCATTERING OF SHOWERS AND
STORMS...MAINLY TO THE EAST KDHN AND KECP...AND IT IS THE EASTERN
TERMINALS OF KTLH...KABY...AND KVLD THAT WILL SEE THE BEST CHANCES
FOR BRIEF VIS/CIG RESTRICTIONS ASSOCIATED WITH PASSING SHOWERS.
CONVECTION WILL DISSIPATE WITH THE SETTING OF THE SUN THIS EVENING
GIVING WAY TO PREVAILING VFR CONDITIONS THROUGH MUCH OF THE
OVERNIGHT. PATCHES OF MVFR VIS ARE POSSIBLE TOWARD DAWN...ESPECIALLY
FOR THOSE TERMINALS WHICH RECEIVE MEASURABLE RAINFALL TODAY.

&&

.FIRE WEATHER...
RELATIVE HUMIDITY VALUES ARE GENERALLY EXPECTED TO REMAIN ABOVE
CRITICAL LEVELS OVER THE NEXT COUPLE OF DAYS. SHOWERS AND
THUNDERSTORM ACTIVITY DURING THE AFTERNOON AND EARLY EVENING IS
EXPECTED TO BE ONLY ISOLATED IN NATURE.
