The radar

The Miami radar (KAMX), 90 km from the middle of the area, began a volume at 20:30 UTC, the scan nearest the moment this went out.

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 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 84 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 13, 2:56 PM EDT, 1 hour 32 minutes earlier.

Area forecast discussion, Jun 13, 2:56 PM EDT, 1 hour 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
256 PM EDT SAT JUN 13 2009

.DISCUSSION...
OVERALL...EXPECT SIMILAR CONDITIONS TO THE PAST SEVERAL AFTERNOONS
TO OCCUR ACROSS SOUTH FLORIDA ONCE AGAIN TODAY...WITH EARLY
AFTERNOON VISIBLE SATELLITE IMAGERY INDICATING THE DEVELOPMENT OF
ENHANCED CUMULUS CLOUDS ACROSS THE SOUTHERN 2/3RDS OF THE FORECAST
AREA. AFTERNOON CONVECTION SHOULD ONCE AGAIN BE FOCUSED ALONG
INLAND MOVING ATLANTIC/GULF COAST SEA BREEZES AND LAKE BREEZE...
WITH NORTH/NORTHEASTERLY STEERING FLOW ALLOWING SHOWERS/STORMS
THAT DEVELOP IN THIS REGION TO SPREAD SOUTH-SOUTHWESTWARD.
HOWEVER...ONE SUBTLE CHANGE FROM PREVIOUS DAYS IS THAT THE LOWER
/MID-LEVEL RIDGE AXIS HAS APPARENTLY SHIFTED A BIT FURTHER TO THE
SOUTH TODAY...PLACING THE NORTHERN THIRD OF THE AREA IN A LIGHT
WESTERLY STEERING FLOW. FOR THIS REASON...WILL MAINTAIN SLIGHTLY
HIGHER AFTERNOON RAIN CHANCES ACROSS THE NORTHEAST QUADRANT OF THE
FORECAST AREA AS WELL.

A POTENTIALLY MORE SIGNIFICANT FEATURE OF INTEREST WILL ENTER THE
FORECAST PICTURE TONIGHT...AS SHORT TERM MODELS NOW SUGGEST THAT
A WELL-DEFINED MID-LEVEL SHORTWAVE TROUGH -- CURRENTLY SEEN IN
WATER VAPOR DATA ACROSS ALABAMA/GEORGIA -- WILL MOVE SOUTHEASTWARD
AROUND NORTHEASTERN FLANK OF MID-LEVEL ANTICYCLONE CENTERED ACROSS
SOUTH TEXAS. NOT ONLY WILL THIS FEATURE OFFER MORE LARGE SCALE
SUPPORT FOR UPWARD VERTICAL MOTIONS NECESSARY TO MAINTAIN
AFTERNOON CONVECTION...BUT ITS APPROACH WILL ALSO BACK STEERING
FLOW TO THE NORTH-NORTHWEST...ALLOWING ANY EVENING/NOCTURNAL
CONVECTIVE ACTIVITY ACROSS CENTRAL FLORIDA TO AFFECT THE REGION
FROM LAKE OKEECHOBEE TO THE PALM BEACH COAST...AND WILL LEAVE
SLIGHT CHANCE POPS ACROSS THIS AREA. ALTHOUGH ALL GUIDANCE
INDICATES THAT THIS SHORTWAVE TROUGH WILL WEAKEN AS IT DRIFTS
ACROSS SOUTH FLORIDA TOMORROW...THE PRESENCE OF ITS REMNANTS WILL
RESULT IN LOWER HEIGHTS ALOFT...AND A CONTINUATION OF NNW STEERING
FLOW WILL LIKELY MEAN A MORE ACTIVE DAY OF THUNDERSTORM ACTIVITY
ALONG THE SOUTHEAST ATLANTIC COAST OF THE PENINSULA. ASIDE FROM
LINGERING ACTIVITY ON SUNDAY EVENING...EXPECT GENERALLY QUIET
CONDITIONS TO PREVAIL OVERNIGHT. THE POTENTIAL DOES EXIST FOR A
REPEAT PERFORMANCE ON MONDAY...AS ANOTHER WEAK MID-LEVEL WAVE MAY
MOVE ACROSS SOUTH FLORIDA IN DIFFLUENT N/NW FLOW ALOFT.

WILL BE MAKING NO CHANGES TO THE EXTENDED PORTION OF THE FORECAST
AT THIS TIME...AS GLOBAL MODELS CONTINUE TO SHOW SIMILAR
PATTERNS FROM TUESDAY THROUGH SATURDAY. ALL GUIDANCE INDICATES
THAT THE MID-LEVEL RIDGE OVER THE NORTHERN GULF/SOUTHERN PLAINS
WILL RETROGRADE SLIGHTLY DURING THE BEGINNING OF THE EXTENDED
PERIOD...AS A STRONG UPPER TROUGH DEVELOPS OVER THE PACIFIC COAST.
THIS MAY SERVE TO INCREASE RAIN CHANCES DURING THIS PERIOD...AS
SUBSIDENT INFLUENCES OF THE RIDGE MAY BE DIMINISHED...AND STRONG
NORTHERLY FLOW WILL UNDOUBTEDLY BRING ADDITIONAL IMPULSES ALOFT
SOUTHWARD OVER THE AREA. TOWARD THE END OF THE WEEK...THE GFS
DEVELOPS A STRONGER UPPER TROUGH OVER THE GREAT LAKES REGION AND
NORTHEAST U.S. AND CONSEQUENTLY MAINTAINS HIGHER RAIN CHANCES FOR
SOUTH FLORIDA...WITH THE ECMWF INDICATING MORE RIDGING REMAINING
ACROSS THE REGION. THE PREVIOUS FORECAST HAS THIS TREND
ESTABLISHED...AND HAVE NO REASON TO MAKE ANY CHANGES AT THIS
TIME.

&&

.MARINE...
WINDS ACROSS THE LOCAL WATERS THROUGH THE SHORT TERM PORTION OF
THE MARINE FORECAST WILL RANGE FROM SOUTH AROUND 10 KNOTS IN THE
ATLANTIC...TO WEST-SOUTHWEST AT 5 KNOTS OR LESS ACROSS THE
SOUTHEASTERN GULF. THIS WILL RESULT IN PREVAILING SEAS OF 2-3 FEET
IN THE ATLANTIC WATERS AND 1-2 FEET IN THE GULF...OUTSIDE OF
SHOWER/THUNDERSTORM ACTIVITY...WHICH COULD OCCUR AT ANY TIME. AS
MENTIONED BY PREVIOUS FORECASTER...LIGHT WINDS IN THE LOWER
TROPOSPHERE WILL PROMOTE AN ENHANCED THREAT FOR WATERSPOUTS ALONG
ANY CLOUD CONVERGENCE BANDS...ESPECIALLY ACROSS THE ATLANTIC.

&&

.FIRE WEATHER...
MINIMUM AFTERNOON RH VALUES WILL LIKELY CONTINUE TO FALL INTO THE
40-45 PERCENT RANGE ACROSS MUCH OF THE INTERIOR PENINSULA
THROUGH THE MIDDLE OF NEXT WEEK...AS TEMPERATURES WARMING INTO THE
UPPER 90S LEAD TO DEEP BOUNDARY LAYER MIXING.

...SCATTERED STRONG TO SEVERE THUNDERSTORMS INTERIOR AND WEST...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT

THUNDERSTORMS: SCATTERED THUNDERSTORMS WILL AFFECT MAINLY INTERIOR
AND WESTERN SECTIONS OF SOUTH FLORIDA THROUGH EARLY EVENING,
INCLUDING WESTERN SECTIONS OF THE EASTERN METRO AREAS. SOME OF THESE
STORMS MAY BE STRONG TO SEVERE, WITH LARGE HAIL AND WIND GUSTS TO
60 MPH POSSIBLE. FREQUENT LIGHTNING STRIKES AND LOCALLY HEAVY
RAINFALL WILL ALSO OCCUR WITH THESE STORMS.

WATERSPOUTS: THE WINDS IN THE LOWER AND MID LEVELS OF THE ATMOSPHERE
ALONG WITH LINGERING BOUNDARIES WILL HELP TO POSSIBLY PRODUCE A FEW
WATERSPOUTS OVER THE GULF OF MEXICO AND THE ATLANTIC OCEAN.

WIND: THE STRONGEST STORMS MAY PRODUCE WIND GUSTS TO 60 MPH
ACROSS THE WESTERN SUBURBS OF THE EAST COAST AND INTERIOR AND
WESTERN PENINSULA SECTIONS THIS AFTERNOON AND EVENING.

HAIL: HAIL UP TO QUARTER SIZE IN DIAMETER WILL BE POSSIBLE WITH THE
STRONGEST THUNDERSTORMS THIS AFTERNOON AND EVENING, MOST LIKELY
ACROSS THE WESTERN SUBURBS OF THE EAST COAST AS WELL AS INTERIOR
AND WESTERN SECTIONS OF MAINLAND SOUTH FLORIDA.

FLOODING: LOCALIZED FLOODING MAY OCCUR WITH SLOW MOVING
THUNDERSTORMS OVER INLAND AND WESTERN SECTIONS THIS AFTERNOON AND
EVENING.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THUNDERSTORMS WILL CONTINUE DAILY THROUGH NEXT WEEK. LIGHTNING
STRIKES, LOCALLY HEAVY RAINFALL AND GUSTY WINDS WILL BE THE
PRIMARY THREATS WITH THIS ACTIVITY. THERE WILL ALSO BE THE
LINGERING THREAT OF WATERSPOUTS THROUGH EARLY NEXT WEEK IN THE
GULF OF MEXICO AND THE ATLANTIC DUE TO LIGHT WINDS IN THE LOWER
AND MID LEVELS OF THE ATMOSPHERE.

.SPOTTER INFORMATION STATEMENT...

WIDESPREAD SPOTTER ACTIVATION IS NOT ANTICIPATED, HOWEVER
INDIVIDUAL SPOTTERS ARE ENCOURAGED TO REPORT HIGH WIND, HAIL AND
FLOODING TO THE NATIONAL WEATHER SERVICE MIAMI FORECAST OFFICE.
