What was reported inside it

Time	Report	Where	Remark
Jun 23, 5:30 PM EDT	TSTM WND GST 50	Weston, FL	PUBLIC REPORTED WIND GUSTS OF 50 MPH ALONG WITH PEA SIZE HAIL IN WESTON.

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, 8.5 hours before the alert went out and 39 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 Jun 23, 3:35 PM EDT, 52 minutes earlier.

Area forecast discussion, Jun 23, 3:35 PM EDT, 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
335 PM EDT MON JUN 23 2008

.DISCUSSION...
SIMILAR CONDITIONS TO PREVIOUS DAYS EXIST ACROSS SOUTH FLORIDA
THIS AFTERNOON...WITH A VERY UNSTABLE AIRMASS IN PLACE OVER THE
AREA CHARACTERIZED BY LI VALUES RANGING FROM -8 TO -10 AND CAPE OF
4500-5000 J/KG. HOWEVER...ONE NOTEWORTHY DIFFERENCE FROM PREVIOUS
DAYS IS A DEEPER LAYER OF MODERATE SOUTHEAST FLOW IN THE LOWER
LEVELS OF THE TROPOSPHERE...WITH RESULTANT BROAD WARM ADVECTION
REGIME AND SYNOPTIC SCALE ASCENT ALLOWING SHOWERS/THUNDERSTORMS TO
DEVELOP EVEN AWAY FROM REGIONS OF STRONGER LOW-LEVEL CONVERGENCE.
EXPECT NUMEROUS SHOWERS/STORMS TO CONTINUE ACROSS THE AREA THROUGH
EARLY EVENING...WITH MORE OF A SSW-TO-NNE COMPONENT TO STEERING
FLOW ALLOWING RESIDUAL EVENING ACTIVITY TO BECOME CONCENTRATED
ACROSS THE NORTHEAST QUADRANT OF THE FORECAST AREA.

SHORT TERM SOLUTIONS FROM THE NGM/NAM/GFS ARE IN REASONABLY GOOD
AGREEMENT THAT CONDITIONS ON THE SYNOPTIC SCALE WILL REMAIN
FAIRLY STAGNANT ACROSS THE FORECAST AREA THROUGH THE REMAINDER OF
THE SHORT TERM PORTION OF THE FORECAST...WITH A WEAKNESS IN THE
SUBTROPICAL UPPER RIDGE FORECAST TO REMAIN IN PLACE OVER THE
WESTERN/CENTRAL GULF OF MEXICO. WITH MODERATE EASTERLY LOW-LEVEL
FLOW EXPECTED TO CONTINUE OVERNIGHT...WILL HOLD ONTO AT LEAST LOW
CHANCE POPS FOR THE EASTERN HALF OF THE PENINSULA AND ADJACENT
COASTAL WATERS. RICH MOISTURE AND INCREASING LOW-LEVEL CONVERGENCE
ALONG THE ATLANTIC COAST ON TUESDAY WILL RESULT IN ANOTHER ACTIVE
DAY OF CONVECTION...WITH AN EVEN DEEPER AND MORE ESTABLISHED
EASTERLY FLOW REGIME EXPECTED TO CONCENTRATE SHOWER/STORM ACTIVITY
ALONG THE GULF COAST BY LATE AFTERNOON. BY TUESDAY NIGHT...MOST OF
THE GLOBAL MODELS SUGGEST THAT A VERY WEAK TROPICAL WAVE WILL BE
APPROACHING SOUTH FLORIDA FROM THE SOUTHEAST...WITH A SURGE OF
STRONGER EASTERLY FLOW EXPECTED TO SPREAD OVER THE AREA THROUGH
THE NIGHT. NOCTURNAL PRECIPITATION IN THIS REGIME SHOULD BE
CONFINED TO THE EAST COAST ONCE AGAIN ON TUESDAY NIGHT...WITH
PRECIPITATION CHANCES ON WEDNESDAY A BIT MORE UNCERTAIN AT THIS
TIME. ALTHOUGH ALL GUIDANCE FORECASTS DEEP WARM ADVECTION AND
FAVORABLE LOW-LEVEL CONVERGENCE ALONG THE ATLANTIC COAST...
ACCOMPANIED BY A SURGE IN PWATS TO 2-2.25 INCHES...THERE IS SOME
CONCERN THAT LARGE SCALE SUBSIDENCE PRECEDING THIS SYSTEM WILL
LIMIT THE COVERAGE OF PRECIPITATION ON WEDNESDAY. GIVEN
UNCERTAINTY AT THIS POINT...WILL MAINTAIN HIGH CHANCE POPS AT THIS
TIME...WITH ANOTHER GOOD CHANCE OF SHOWERS/STORMS ALONG THE
ATLANTIC COAST ON WEDNESDAY NIGHT.

THE PREVIOUSLY MENTIONED WAVE IS FORECAST BY MOST OF THE GLOBAL
MODEL GUIDANCE TO SHIFT NORTHWESTWARD AT THE BEGINNING OF THE
EXTENDED FORECAST PERIOD...WITH THE WESTERN EXTENT OF UPPER RIDGE
OVER THE ATLANTIC BUILDING OVER THE REGION ON FRIDAY/SATURDAY.
THIS WILL LIKELY LIMIT THE COVERAGE OF AFTERNOON CONVECTION TO THE
LAKE REGION AND NORTHWEST INTERIOR. BY THE END OF THE FORECAST
PERIOD...THE LATEST GFS/ECMWF BOTH SUGGEST THAT UPPER RIDGE WILL
WEAKEN AS A STRONG UPPER LOW SHIFTS EASTWARD OVER THE GREAT LAKES
REGION. THIS...COUPLED WITH A RETURN TO A SOUTHWEST STEERING FLOW
REGIME MAY ALLOW FOR HIGHER POPS ALONG THE EAST COAST...BUT
CURRENT FORECAST HAS THIS ADDRESSED AND WILL MAKE NO CHANGES AT
THIS TIME.

&&

.AVIATION...
SHOWERS AND THUNDERSTORMS WERE DEVELOPING OVER THE PALM BEACH METRO
AREAS EARLY THIS AFTERNOON. THESE SHOWERS AND THUNDERSTORMS SHOULD
AFFECT THE PBI TAF SITE BETWEEN 18 AND 19Z THIS AFTERNOON. SO HAVE
PUT A TEMPO IN FOR THIS TAF SITE WITH REDUCE VIS DOWN INTO THE MVFR
CONDITIONS. FOR REST OF THE AFTERNOON HOURS HAVE LEFT A VCTS IN FOR
PBI TAF SITE.

FOR REST OF THE EAST COAST TAF SITES...WILL CONTINUE WITH THE VCTS
FOR THE AFTERNOON HOURS BEFORE GOING TO VCSH FROM 00Z UNTIL 02Z FOR
THE DIEING SHOWERS. FOR APF TAF SITE...WILL ALSO CONTINUE THE VCSH
UNTIL 21Z BEFORE GOING DRY.

THE WINDS WILL ALSO REMAIN FROM THE EAST OVER ALL OF THE TAF SITES
AT 10 KNOTS OR LESS FOR THIS AFTERNOON INTO TONIGHT...WHILE APF TAF
SITE WILL REMAIN OUT OF THE WEST THIS AFTERNOON BEFORE SWINGING TO
THE EAST AFTER 00Z WITH SPEEDS BELOW 10 KNOTS.

&&

.MARINE...
AN EASTERLY FLOW REGIME WILL GRADUALLY BECOME MORE ESTABLISHED
ACROSS THE LOCAL COASTAL WATERS THROUGH TUESDAY...WITH FLOW
LIKELY INCREASING TO AT LEAST SCEC CRITERIA BY LATE TUESDAY...AS
THE GRADIENT STRENGTHENS IN RESPONSE TO A WEAK TROPICAL WAVE
APPROACHING THE REGION FROM THE SOUTHEAST. SMALL CRAFT ADVISORIES
MAY BE REQUIRED FOR THE GULF STREAM FROM WEDNESDAY INTO
THURSDAY...AS SEAS INCREASE TO 6-7 FEET. SOUTHEAST FLOW WILL
PERSIST BUT SHOULD GRADUALLY WEAKEN THROUGH THE END OF THE
FORECAST PERIOD. EXPECT SLIGHTLY LOWER WIND SPEEDS OVER THE GULF
WATERS...WITH SEAS OFF SHORE RANGING FROM 3-4 FEET.

ASIDE FROM INCREASING WINDS/WAVES...THE STRONG ONSHORE FLOW WILL
RESULT IN A SIGNIFICANT INCREASE IN THE RISK OF RIP CURRENTS ALONG
THE ATLANTIC COAST.

&&

.FIRE WEATHER...
THERE ARE NO FIRE WEATHER RELATED CONCERNS THROUGHOUT THE FORECAST
PERIOD...WITH MINIMUM AFTERNOON RH VALUES EXPECTED TO REMAIN
SUFFICIENTLY HIGH.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS: NUMEROUS THUNDERSTORMS ARE EXPECTED ACROSS MOST OF
NORTHERN INTERIOR AND NORTHEAST SECTIONS OF MAINLAND SOUTH FLORIDA ONCE
AGAIN THIS AFTERNOON, WITH SCATTERED THUNDERSTORMS OVER REST OF
SOUTH FLORIDA. THE PRIMARY HAZARD EXPECTED WITH THESE STORMS WILL
BE STRONG GUSTY WINDS...SMALL HAIL...FREQUENT TO EXCESSIVE
LIGHTNING STRIKES...AND LOCALLY HEAVY RAINFALL.

WIND: THE STRONGEST STORMS TODAY COULD PRODUCE WIND GUSTS UP TO 60
MPH MAINLY OVER THE NORTHERN INTERIOR AND NORTHEAST AREAS OF SOUTH
FLORIDA, WHERE THE SEA BREEZES AND LAKE BREEZE COLLIDE.

HAIL: THE MID LEVELS OF THE ATMOSPHERE REMAINS COOL TODAY OVER
SOUTH FLORIDA. THIS WILL ALLOW FOR THE STRONGEST STORMS TO
PRODUCE HAIL UP TO PENNY SIZE MAINLY OVER THE NORTHERN INTERIOR
AND NORTHEAST AREAS OF SOUTH FLORIDA TODAY WHERE THE SEA BREEZES
AND LAKE BREEZE COLLIDE.

FLOODING: LIGHT SOUTHWESTERLY STEERING FLOW WILL RESULT IN A SLOW
MOVEMENT OF ANY STORM THAT DEVELOPS TODAY. THIS, IN TURN, WILL
RESULT IN LOCALLY HEAVY RAINFALL, LEADING TO PONDING OF WATER IN
POORLY DRAINED LOCATIONS.

VISIBILITY: A MIXTURE OF SMOKE AND FOG TO THE IMMEDIATE WEST OF
SMOLDERING WILDFIRES AROUND THE WESTERN EDGE OF LAKE OKEECHOBEE MAY
RESULT IN VISIBILITY REDUCTIONS TO ONE MILE OR LESS LATE TONIGHT.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

THERE IS A CHANCE OF MAINLY AFTERNOON AND EVENING THUNDERSTORMS
ACROSS THE ENTIRE AREA AT LEAST THROUGH WEDNESDAY. LIGHTNING STRIKES
WILL BE THE PRIMARY HAZARD, WITH ORGANIZED SEVERE WEATHER NOT
