The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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

Tampa Bay, FL (KTBW), launched 00:00Z, 1.4 hours before the alert went out and 127 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, Sep 20, 8:23 PM EDT, 1 hour 2 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
823 PM EDT THU SEP 20 2007

.DISCUSSION...BUSY DAY WEATHER WISE...SO SHORT AFD. HAD SEVERAL
STRONG TO SEVERE WIND REPORTS WITH LINE THAT DEVELOPED OVER
CENTRAL FLORIDA AND PUSHED NORTH. GIVEN LACK OF DAYTIME HEATING
EXPECT NEWER LINES TO THE SOUTH TO NOT BE SEVERE...BUT MAY STILL
SEE SOME GUSTY WINDS. WILL KEEP BEST CHANCES FOR RAIN NEAR THE
COAST OVERNIGHT...AND BUMP UP TO NUMEROUS WHERE PREVIOUSLY HAD 50
PERCENT. HAVE TWEAKED TEMPERATURES UP A DEGREE TO MAINTAIN A
SIMILAR TEMPERATURE THROUGH THE NIGHT...GIVEN MORE TROPICAL AIR
MOVING INTO THE REGION. UPDATE WILL COME OUT SHORTLY.

&&

.AVIATION...INTERVALS OF MVFR WITH BRIEF PERIODS OF IFR CEILINGS AND
VISIBILITIES WILL CONTINUE TO IMPACT THE TERMINAL SITES OVERNIGHT INTO
FRIDAY AS BANDS OF RAIN AND EMBEDDED THUNDERSTORMS ASSOCIATED WITH AN
AREA OF LOW PRESSURE OVER THE EASTERN GULF WATERS MOVES ACROSS THE
REGION. SOUTHEAST TO SOUTHERLY WINDS IN THE 10-15 KNOT RANGE WILL BE
THE RULE...HOWEVER GUSTS UP TO 30 KNOTS WILL BE POSSIBLE WITH SOME OF
THE RAIN BANDS. OUTSIDE OF THE RAIN AREAS...VFR CONDITIONS ARE
EXPECTED.

&&

.MARINE...ONLY BUOY REPORTING STRONG WINDS OUTSIDE OF CONVECTION
IS OFF OF PASCO COUNTY...WHICH HAD 20 KNOTS. THOUGH OTHER SITES
ARE NOT REPORTING ADVISORY WINDS...WOULD STILL PREFER TO KEEP IT
UP THROUGH THE NIGHT FOR ALL GULF WATERS GIVEN CHANCE FOR MULTIPLE
BANDS OF GUSTY SHOWERS MOVING THROUGH AS WELL AS EXPECTATION THAT
GRADIENT WINDS WILL PICK UP.

&&

.TBW WATCHES/WARNINGS/ADVISORIES...
FL...SMALL CRAFT ADVISORY UNTIL 11 AM EDT FRIDAY FOR PINELLAS.

HAZARDOUS WEATHER OUTLOOK

MANATEE-HARDEE-HIGHLANDS-SARASOTA-DE SOTO-CHARLOTTE-LEE-
517 AM EDT THU SEP 20 2007

THIS HAZARDOUS WEATHER OUTLOOK IS FOR WEST CENTRAL AND SOUTHWEST
FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

...THUNDERSTORM IMPACT...
LOW PRESSURE WILL MOVE ACROSS THE PENINSULA AND INTO THE EASTERN
GULF THIS MORNING. SHOWERS AND THUNDERSTORMS WILL INCREASE IN
COVERAGE AS WINDS SHIFT TO THE SOUTH AND SOUTHEAST. FORECAST SHEAR
PROFILES SUGGEST THAT THERE IS A SLIGHT RISK OF WEAK SHORT-LIVED
TORNADOES TODAY. THE THREAT FOR WEAK TORNADOES MAY CONTINUE NEAR
THE COAST EARLY TONIGHT...BUT SHOULD DIMINISH AS THE LOW PRESSURE
AREA MOVES AWAY.

SMALL TORNADOES CAN CAUSE DAMAGE TO TREES...POWER LINES...AND
POORLY CONSTRUCTED BUILDINGS. STAY TUNED TO NOAA WEATHER RADIO OR
YOUR LOCAL MEDIA FOR FURTHER UPDATES.

...FLOOD IMPACT...
LOCALLY HEAVY RAINFALL IS POSSIBLE ACROSS THE REGION TODAY AND
TONIGHT. HEAVY RAINS MAY CAUSE MINOR FLOODING OF POOR DRAINAGE
AND LOW LYING AREAS. SMALL STREAMS MAY BRIEFLY EXCEED BANK FULL.

...RIP CURRENT IMPACT...
THERE WILL BE AN INCREASING THREAT OF RIP CURRENTS TODAY AS WINDS
TURN MORE SOUTHERLY. THE AREA MOST AT RISK WILL BE FROM BONITA
BEACH TO JOHNS PASS...WHERE WINDS ARE MOST LIKELY TO TURN ONSHORE.
TO THE NORTH...WINDS SHOULD REMAIN MAINLY OFFSHORE TODAY.

A RIP CURRENT IS A 10 TO 30 YARD WIDE CHANNEL OF WATER THAT CAN
PULL EVEN A STRONG SWIMMER INTO DEEPER WATER.

 TO AVOID GETTING CAUGHT IN A RIP CURRENT...SWIM AT GUARDED
BEACHES AND HEED THE ADVICE OF THE BEACH PATROL.  AT UNGUARDED
BEACHES AND NEAR PIERS...JETTIES...AND INLETS...DO NOT GO INTO THE
SURF MUCH ABOVE YOUR KNEES.

 IF CAUGHT IN THE SEAWARD PULL OF A RIP CURRENT...DO NOT ATTEMPT
TO MOVE DIRECTLY TOWARD SHORE.  INSTEAD...MOVE SIDEWAYS ACROSS THE
RIP CURRENT UNTIL THE PULL EASES.  ANOTHER METHOD OF ESCAPE IS TO
LET THE RIP CURRENT PULL YOU SEAWARD 50 TO 100 YARDS...WHERE THE
FORCE WEAKENS.  THEN...SWIM TOWARD THE BEACH AT AN ANGLE AWAY FROM
THE CURRENT.

...MARINE HAZARDS...
NUMEROUS SHOWERS AND THUNDERSTORMS WILL DEVELOP OVER THE GULF
WATERS TODAY. CONDITIONS APPEAR FAVORABLE FOR THE FORMATION OF
WATERSPOUTS. ALSO...STRONG WINDS AND ROUGH SEAS THIS MORNING MAY
ABATE BRIEFLY TODAY...BUT WILL LIKELY PICK UP AGAIN TONIGHT.
FISHERMEN AND OTHER SMALL CRAFT OPERATORS MAY WANT TO POSTPONE
TRIPS UNTIL CONDITIONS IMPROVE.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.

SHOWERS AND THUNDERSTORMS WILL BE LESS PREVALENT ON FRIDAY AS SOME
DRY AIR MOVES ACROSS THE STATE. THIS DRY AIR WILL BE SHORT LIVED
AS THE NEXT BATCH OF MOISTURE MOVES IN FROM THE EAST BY SATURDAY.
SCATTERED TO LOCALLY NUMEROUS THUNDERSTORMS WILL OCCUR EACH
AFTERNOON...WITH THE PRIMARY THREAT BEING DEADLY CLOUD TO GROUND
LIGHTNING AND HEAVY RAIN.

HAZARDOUS BOATING CONDITIONS WILL CONTINUE ON FRIDAY...BUT SHOULD
IMPROVE RAPIDLY OVER THE WEEKEND.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS SHOULD MONITOR THE WEATHER AND SELF ACTIVATE IF NEEDED.
