What was reported inside it

Time	Report	Where	Remark
May 13, 5:40 PM EDT	HAIL 0.25	Plantation, FL	DIME SIZE HAIL REPORTED AT THE INTERSECTION OF SUNRISE BLVD. AND NW 16TH STREET. ALSO STRONG WIND GUSTS.

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

Miami, FL (KMFL), launched 12:00Z, 9.2 hours before the alert went out and 41 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 Miami, FL wrote its last area forecast discussion before this severe thunderstorm warning went out at May 13, 2:57 PM EDT, 2 hours 15 minutes earlier.

Area forecast discussion, May 13, 2:57 PM EDT, 2 hours 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
257 PM EDT SUN MAY 13 2007

.DISCUSSION...ISOLATED STORMS DEVELOPED SUNDAY AFTERNOON ACROSS
NRN PORTIONS OF MAINLAND SOUTH FLORIDA WITH A COUPLE OF THEM
REACHING NEAR SEVERE LEVELS. A RATHER UNSTABLE AIRMASS WITH VERY
COLD TEMPERATURES ALOFT...DIURNAL HEATING AND LAKE/SEA BREEZES
WERE THE MAIN MECHANISM FOR THE DEVELOPMENT OF THESE STORMS. A
FRONTAL BOUNDARY ACROSS NRN FLORIDA WILL DRIFT SOUTH TO MAINLAND
SOUTH FLORIDA THROUGH TUE MORNING. THIS WILL ACT AS A FOCUSING
MECHANISM FOR DAILY SHWRS/TSTMS ACROSS THE FORECAST AREA. BOTH GFS
AND NAM INDICATES INCREASING MOISTURE DURING THIS PERIOD AND GFS
EVEN INDICATES POPS IN THE HIGH CHANCE TO NMRS CATEGORY. DECIDED
TO KEEP IT IN THE HIGH CHANCE AND NOT GO AS HIGH AS GFS YET.

A SFC RIDGE WILL MOVE EAST OVER THE WRN ATLANTIC BEHIND THIS
FRONTAL BOUNDARY AND WILL ESTABLISH JUST N OF 30N WITH RIDGE
EXTENDING WEST TO NRN GULF. THIS WILL KEEP A LOW LVL EAST FLOW
WHICH WILL KEEP A MODERATE AMOUNT OF MOISTURE COMING INTO THE
AREA WITH A CHANCE FOR SHWRS/TSTMS EACH DAY. LOOKS LIKE THE RAINY
SEASON IS FINALLY ON THE WAY.

&&

.AVIATION...ISOLD SHWRS/TSTMS SHOULD CONTINUE TO DEVELOP ALONG
BOTH COASTS SEA BREEZES REST OF THE AFTERNOON INTO EARLY EVENING
HOURS. WL INDICATE TEMPO FOR KPBI AND KFLL AND VCNTY SHWRS FOR
KMIA/KTMB. VFR CONDITIONS WILL PREVAIL FOR KAPF.

&&

.MARINE...WINDS AND SEAS WILL REMAIN ON THE LIGHT SIDE THROUGH
MONDAY NIGHT. AS SFC HIGH MOVES EAST OVER WRN ATLC AND PRESSURE
GRADIENT TIGHTENS OVER OUR LOCAL WATERS...WINDS WILL INCREASE TO
THE 15 TO 20 KTS RANGE. A SMALL NORTHEAST SWELL WILL BEGIN TO
AFFECT OUR ATLC WATERS TUE AT WHICH TIME SEAS MAY BUILD UP TO 7 FEET.

&&

.FIRE WEATHER...NO PROBLEMS EXPECTED. WITH THE LOW LVL FLOW
BECOMING EAST AND DEWPOINTS INCREASING THROUGH THIS
PERIOD...RELATIVE HUMIDITIES SHOULD REMAIN WELL ABOVE CRITICAL VALUES.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TODAY AND TONIGHT

THIS AFTERNOON ACROSS INTERIOR SOUTH FLORIDA AND THEN MOVE TOWARDS
THE EAST COAST. THESE STORMS WILL CONTAIN FREQUENT LIGHTNING
STRIKES...GUSTY WINDS...HAIL...AND BRIEF VERY HEAVY RAINFALL.

WIND: SOME OF THE STRONGEST STORMS COULD PRODUCE WIND GUSTS TO
AROUND 45 TO 55 MPH.

HAIL: THE STRONGER STORMS COULD PRODUCE DIME SIZE HAIL WITH A
FEW STORMS AROUND LAKE OKEECHOBEE TO PALM BEACH COUNTY PRODUCING
HAIL UP TO ONE INCH.

FLOODING: BRIEF VERY HEAVY RAINFALL IN THE STRONGEST STORMS WILL
CAUSE SOME STANDING WATER ALONG ROADWAYS WHERE THE DRAINAGE IS
POOR OR IN OTHER POORLY DRAINED LOCATIONS.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

AFTERNOON THUNDERSTORM CHANCES WILL INCREASE FOR THE ENTIRE AREA
THIS WEEK, AS DEEPER MOISTURE RETURNS AND FAVORABLE SEA BREEZE
BOUNDARIES DEVELOP ALONG BOTH COASTS.

THE WINDS WILL BE FROM THE EAST AROUND 15 MPH EARLY NEXT WEEK
ALONG WITH LOW TIDE OCCURRING DURING THE DAY HOURS. THIS WILL LEAD
TO AN INCREASE IN RISK OF RIP CURRENTS ALONG THE EAST COAST
