What was reported inside it

Time	Report	Where	Remark
Jun 22, 5:29 PM EDT	TSTM WND GST 47	Southwest Florida Airpo, FL	MEASURED 41 KNOT GUST AT KRSW ASOS.

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

Tampa Bay, FL (KTBW), launched 12:00Z, 9.5 hours before the alert went out and 149 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, Jun 22, 1:58 PM EDT, 3 hours 30 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
158 PM EDT WED JUN 22 2011

.SHORT TERM (TONIGHT-FRIDAY)...
MID/UPPER LEVEL RIDGE WILL BE SUPPRESSED TO THE SOUTH AND EAST AS
A TROUGH SETS UP OVER THE EASTERN U.S. DOWN INTO THE GULF OF
MEXICO DURING THE PERIOD. THIS WILL HELP PULL MORE MOISTURE
NORTHWARD INTO FLORIDA WITH PRECIPITABLE WATER VALUES EXPECTED TO
CLIMB TO BETWEEN 1.8 AND 2.0 INCHES. MEANWHILE AT THE SURFACE A
WEAKENING COOL FRONT WILL MOVE INTO THE SOUTHEAST U.S. WITH THE
RIDGE AXIS REMAINING ACROSS SOUTH CENTRAL FLORIDA. THIS WILL
CONTINUE THE OVERALL LIGHT SOUTHEAST TO SOUTH FLOW ACROSS THE
SOUTHERN AND CENTRAL ZONES AND SOUTH TO SOUTHWEST FLOW ACROSS THE
NORTH. THE WEST COAST SEA BREEZE WILL DEVELOP EACH AFTERNOON AND
SHOULD PUSH INLAND TO AROUND THE INTERSTATE 75 CORRIDOR. FOR
THURSDAY THE BEST CHANCE OF CONVECTION SHOULD BE GENERALLY ALONG
AND EAST OF INTERSTATE 75 ACROSS THE NORTHERN AND CENTRAL ZONES
AND ACROSS THE ENTIRE SOUTH. HAVE LEFT 40 POPS IN THESE AREAS AND
LOWERED TO 30 PERCENT FROM THE TAMPA BAY AREA NORTH NEAR THE
COAST. DURING THURSDAY NIGHT AND FRIDAY A BAND OF DEEPER MOISTURE
ASSOCIATED WITH THE REMNANTS OF THE BOUNDARY WILL MOVE INTO THE
NATURE COAST ENHANCING RAIN CHANCES HERE WITH MORE SCATTERED
AFTERNOON AND EVENING CONVECTION EXPECTED FURTHER SOUTH. HAVE
CONTINUED WITH THE 50 POPS FOR FRIDAY EVERYWHERE AT THIS TIME...
BUT LATER SHIFTS MAY NEED TO RAISE POPS ACROSS THE NATURE COAST
AND LOWER THEM ACROSS THE SOUTH. TEMPERATURES WILL BE NEAR TO
SLIGHTLY ABOVE NORMAL THROUGH THE SHORT TERM PERIOD.

.LONG TERM (FRIDAY NIGHT-WEDNESDAY)...
HIGH PRESSURE WILL RIDGE ACROSS THE AREA THROUGH THE PERIOD WITH
THE RIDGE AXIS REMAINING IN PLACE ACROSS NORTHERN FLORIDA. A WEAK
TROUGH WILL BE IN PLACE TO THE WEST AT THE UPPER LEVELS WITH WEAK
RIDGING ACROSS SOUTHERN FLORIDA. AFTERNOON SEA BREEZES WILL
DEVELOP ALONG THE COAST IN THE SOUTH TO SOUTHEAST PREDOMINANT FLOW
EACH DAY. SCATTERED THUNDERSTORMS WILL DEVELOP ALONG THE SEA
BREEZE AND OUTFLOW BOUNDARIES EACH AFTERNOON AND CONTINUE THROUGH
AROUND MIDNIGHT EACH NIGHT. TEMPERATURES WILL BE A DEGREE OR TWO
ABOVE NORMAL EACH DAY WITH HIGHS AROUND 90 TO THE LOWER 90S...AND
LOWS IN THE LOWER TO MID 70S EXCEPT UPPER 70S ALONG THE COAST.

&&

.AVIATION...
SOUTHWEST/WEST FLOW WILL CONTINUE NEAR THE COAST THROUGH THE
EARLY EVENING HOURS. PIE MAY STILL EXPERIENCE NE WINDS THROUGH MID
AFTERNOON AS THE BAY BREEZE GRADUALLY WEAKENS. A FEW THUNDERSTORMS
ARE POSSIBLE...MAINLY IN THE VICINITY OF FMY AND RSW WITH BRIEF
MVFR/LOCAL IFR CONDITIONS THROUGH EARLY THIS EVENING. CONVECTION
SHOULD REMAIN EAST OF TPA/PIE/SRQ THIS AFTERNOON...BUT COULD
MOVE BACK TOWARD THESE SITES THIS EVENING. WINDS WILL AGAIN BECOME
LIGHT AND SKIES CLEAR AFTER 02Z. A SIMILAR DAY WEATHERWISE IS
EXPECTED ON THURSDAY.

&&

.MARINE...
THE SURFACE HIGH PRESSURE RIDGE AXIS WILL REMAIN ACROSS THE REGION
FOR THE NEXT FEW DAYS SUPPORTING LIGHT WINDS AND SLIGHT SEAS FOR THE
NEXT FEW DAYS. A SEA BREEZE WILL DEVELOP ALONG THE COAST EACH
AFTERNOON.

&&

.FIRE WEATHER...
NO FIRE WEATHER HIGHLIGHTS OVER THE NEXT FEW DAYS AS LOW LEVEL
MOISTURE WILL BE INCREASING KEEPING RELATIVE HUMIDITY VALUES
ABOVE CRITICAL LEVELS.

&&

.PRELIMINARY POINT TEMPS/POPS...

451 AM EDT WED JUN 22 2011

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

.DAY ONE...TODAY AND TONIGHT.

...THUNDERSTORM IMPACT...
A SLOW INCREASE IN MOISTURE WILL ALLOW SCATTERED THUNDERSTORMS TO
DEVELOP OVER WEST CENTRAL AND SOUTHWEST FLORIDA TODAY AS THE EAST
AND WEST COAST SEA BREEZE BOUNDARIES COLLIDE OVER INLAND LOCATIONS
DURING THE LATE AFTERNOON AND EARLY EVENING HOURS. THE STORMS WILL
LIKELY LINGER AND MOVE TOWARD COASTAL LOCATIONS THROUGH THE EVENING
HOURS TONIGHT AS THE SEA BREEZE AND OUTFLOW BOUNDARIES DRIFT TOWARD
THE WEST UNDER A LIGHT EAST SOUTHEAST STEERING FLOW. STORMS THAT
DEVELOP TODAY WILL BE CAPABLE OF PRODUCING LOCALLY HEAVY RAINS...
STRONG GUSTY WINDS...FREQUENT LIGHTNING STRIKES...AND SMALL HAIL.

...EXCESSIVE HEAT IMPACT...
TEMPERATURES CLIMBING INTO THE MID AND UPPER 90S COMBINED WITH A
HUMID AIR MASS WILL PRODUCE HEAT INDICES IN THE 103 TO 109 DEGREE
RANGE OVER INLAND LOCATIONS DURING THE AFTERNOON. IF YOU WORK
OUTDOORS REMEMBER TO DRINK PLENTY OF WATER AND TAKE FREQUENT BREAKS
IN THE SHADE. DO NOT LEAVE CHILDREN OR PETS IN LOCKED VEHICLES!
TEMPERATURES CAN RISE ABOVE 130 DEGREES IN MINUTES...QUICKLY
INCREASING THE CHANCE FOR HEAT STROKE AND POSSIBLE DEATH.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.

...THUNDERSTORM IMPACT...
A CONTINUED INCREASE IN MOISTURE COUPLED WITH UPPER LEVEL
DISTURBANCES AND THE SEA BREEZE CIRCULATIONS WILL FAVOR SCATTERED
SHOWERS AND THUNDERSTORMS ACROSS THE REGION EACH DAY DURING THE
AFTERNOON AND EARLY EVENING HOURS. STORMS THAT DEVELOP WILL BE
CAPABLE OF PRODUCING LOCALLY HEAVY RAINS...FREQUENT LIGHTNING
STRIKES...STRONG GUSTY WINDS...AND SMALL HAIL.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY.
