The radar

The Miami radar (KAMX), 131 km from the middle of the area, began a volume at 17:55 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, 5.9 hours before the alert went out and 105 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 28, 9:37 AM EDT, 4 hours 18 minutes earlier.

Area forecast discussion, May 28, 9:37 AM EDT, 4 hours 18 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
937 AM EDT THU MAY 28 2009

.UPDATE...IMPRESSIVE MCS RACED OFF THE TEXAS COAST AND ACROSS THE
GULF OF MEXICO OVERNIGHT. THIS FEATURE IS OVER THE EASTERN GULF
BUT CLOUD TOPS HAVE WARMED SIGNIFICANTLY OVER THE PAST FEW HOURS.
HIGH CIRRUS IS BEGINNING TO BLOW ACROSS THE AREA. HOWEVER...THERE
ARE BREAKS AND SO ENOUGH HEATING IS ANTICIPATED TODAY TO RESULT IN
ANOTHER ACTIVE AFTERNOON. A FEW STORMS HAVE ALREADY DEVELOPED
ALONG THE MAINLAND MONROE COAST. ADDITIONAL STORMS ARE EXPECTED TO
DEVELOP NEAR THE GULF COAST WITH STORMS DEVELOPING INLAND AND
EVENTUALLY CONSOLIDATING ALONG THE ATLANTIC COAST AS ACTIVITY
CONVERGES WITH A DEVELOPING ATLANTIC SEA BREEZE THIS AFTERNOON.
STRONGER SW LOW LEVEL WINDS SHOULD DELAY THE SEA BREEZE LATER THIS
AFTERNOON AND CLOSER TO THE COAST. WILL BE MONITORING THE
PROGRESSION OF THE DISSIPATING MCS OVER THE EASTERN GULF...BUT
RIGHT NOW A TYPICAL DIURNAL CONVECTIVE DAY IS EXPECTED.

THE MORNING MIAMI SOUNDING SHOWS AN UNSTABLE ATMOSPHERE. ALTHOUGH
MID LEVELS HAVE WARMED WITH AN H5 TEMP OF -8.7...MAX AFTERNOON
CAPE CONTINUES >3000 J/KG...LI IS AROUND -7C...AND IT IS A BIT
MORE MOIST TODAY WITH A PWAT OF 1.76 INCHES. SO THINGS LOOK ON
TRACK FOR ANOTHER ACTIVE DAY WITH STRONG TO EVEN A FEW SEVERE
THUNDERSTORMS POSSIBLE. THERE IS DECENT TURNING OF THE WINDS IN
THE LOWER LEVELS...AND THIS COULD LEAD TO THE POSSIBILITY OF A
TORNADO BRIEFLY SPINNING UP AS STORMS DEVELOP/ENCOUNTER THE
ATLANTIC SEA BREEZE...SO WE WILL ADD THIS MENTION TO THE HAZARDOUS
WEATHER OUTLOOK. /DG

PREV DISCUSSION... /ISSUED 337 AM EDT THU MAY 28 2009/

DISCUSSION...I MUST SAY THIS STRETCH OF MIDNIGHT SHIFTS HAS BEEN
A CHALLENGE AND TONIGHT IS NO EXCEPTION. THE GFS CONTINUES TO
SUFFER FROM CONVECTIVE FEEDBACK AND IS VERY ERRATIC WITH THE POP
NUMBERS. THE MET HAS OUTPERFORMED THE MAV ALL WEEK SO AGAIN WILL
GO MUCH HIGHER THAN MAV GUIDANCE TODAY. THE REAL CONCERN IS THE
LINE OF TSRA IN THE CENTRAL GULF OF MEXICO AND CURRENTLY AT 07Z IS
HOLDING ITS OWN. IN FACT, AT ONE TIME DURING THE NIGHT THE CLOUD
TOPS BEGAN TO WARM BUT THEY ARE ONCE AGAIN COOLING AND IT HAS
DEVELOPED A VERY NICE BOW FEATURE. THE NAM WAS THE ONLY MODEL TO
CATCH ON TO THIS FEATURE AND BROUGHT IT TO JUST OFF THE SOUTHWEST
COAST OF FLORIDA BY 12Z THIS MORNING BUT AT A CONSIDERABLY WEAKER
STATE. HOWEVER, IT HAS NOT BEGUN TO WEAKEN AS OF THIS WRITING AND
THIS COULD REALLY HAMPER THE FORECAST CONDITIONS ACROSS THE
REGION. A FEW SCENARIOS COME TO MIND. THIS LINE OF CONVECTION
COULD HOLD TOGETHER AND THE POPS FOR THE WEST COAST WILL TURN OUT
TO BE TOO LOW AND IT COULD ALSO AFFECT FORECAST TEMPERATURES.
ANOTHER SOLUTION WOULD BE THAT THE NAM TURNS OUT TO BE CORRECT AND
IT DOES WEAKEN BUT A SHIELD OF DENSE DEBRIS CLOUDS COULD SPREAD
ACROSS THE REGION AND INHIBIT DIURNAL HEATING ENOUGH THAT THE
POPS WOULD BE TOO HIGH. IF THIS CONVECTIVE CLUSTER DOES HOLD
TOGETHER, IT WOULD REACH THE GULF COAST WATERS AROUND 13Z OR 14Z
SO AT THAT TIME IT COULD BE DETERMINED WHAT IMPACT IT MIGHT HAVE
ON THE REMAINDER OF THE DAY. SO DEFINITELY SOME UNCERTAINTY TO
TODAYS FORECAST BUT SINCE WESTERLY FLOW IS CONTINUING WILL GO
ALONG WITH WHAT HAS ALREADY BEEN ADVERTISED AND THAT IS TO SAY
WIDESPREAD CONVECTION DEVELOPING OVER INTERIOR SOUTH FLORIDA AND
THEN MOVING TO THE EAST COAST METRO AREA BY THIS AFTERNOON. THEN A
REPEAT PERFORMANCE IS HIGHLY LIKELY FOR FRIDAY AND SATURDAY
AFTERNOONS.

IN THE EXTENDED, THE MODELS HAVE BEEN STRUGGLING JUST HOW MUCH
PUSH THE TROUGH THAT HAS BRINGING US THE WET WEATHER WILL
EVENTUALLY HAVE AND HAVE BEEN BOUNCING AROUND WITH THE NOTION OF A
TROUGH BOUNDARY MOVING INTO SOUTH FLORIDA BRINGING SOME DRYING
ALONG WITH IT. UNTIL WE SEE MORE CONSISTENCY FROM RUN TO RUN WILL
NOT CHANGE MUCH IN THE EXTENDED. IT DOES APPEAR HOWEVER THAT AS
TIME GOES ON SURFACE HIGH PRESSURE WILL SLOWLY BUILD BACK INTO THE
AREA AND THE PATTERN WILL GO BACK TO CONVECTION DEVELOPING ALONG
SEA BREEZE CONVERGENCE BOUNDARIES AND AFFECT MOSTLY THE AREAS AWAY
FROM BOTH COASTS.

MARINE...WEAK PRESSURE GRADIENT WILL CONTINUE AND WITH RIDGE
REMAINING OVER THE FLORIDA KEYS A SOUTHWEST WIND OF LESS THAN 15
KNOTS WILL DOMINATE WITH SEAS LESS THAN 4 FEET THROUGH THE PERIOD.

FIRE WEATHER...NO PROBLEMS OR CONCERNS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS: SCATTERED TO NUMEROUS THUNDERSTORMS WILL OCCUR
TODAY AND INTO EARLY THIS EVENING. MOST ACTIVITY WILL AFFECT
THE EAST COAST AND LAKE OKEECHOBEE REGION. LOCALLY HEAVY RAINS,
FREQUENT LIGHTNING STRIKES, GUSTY WINDS, AND POSSIBLY HAIL CAN BE
EXPECTED. ISOLATED THUNDERSTORMS WILL ALSO BE POSSIBLE ALONG THE
WEST COAST. THESE STORMS MAY BE ACCOMPANIED WITH OCCASIONAL
LIGHTNING AND A BRIEF HEAVY DOWNPOUR.

TORNADOES: THERE IS A VERY SLIM CHANCE THAT A WEAK AND SHORT LIVED
TORNADO MAY OCCUR ACROSS THE EAST COAST METRO THIS AFTERNOON OR
EARLY THIS EVENING ESPECIALLY IF THE SEA BREEZE IS ABLE TO PUSH
INLAND.

WIND: WIND GUSTS TO NEAR 60 MPH WILL BE POSSIBLE IN THE STRONGEST
THUNDERSTORMS OVER THE INTERIOR, LAKE OKEECHOBEE REGION, AND EAST
COAST.

HAIL: NICKEL-SIZED HAIL WILL BE POSSIBLE IN THE STRONGEST THUNDERSTORM
ACTIVITY OVER THE CENTRAL INTERIOR, LAKE OKEECHOBEE REGION, AND
EAST COAST.

FLOODING: THE THUNDERSTORMS WILL BE CAPABLE OF PRODUCING VERY
HEAVY RAIN IN A SHORT PERIOD OF TIME. WITH SOILS ALREADY
SATURATED FROM PREVIOUS RAINS THE PAST FEW DAYS, THIS COULD LEAD
TO LOCALIZED FLOODING OF LOW LYING AND FLOOD PRONE AREAS
ESPECIALLY IN THE EAST COAST METRO.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED EACH AFTERNOON
THROUGH THE COMING WEEK WITH SOME ISOLATED STRONG TO POSSIBLY SEVERE
STORMS POSSIBLE THROUGH THE END OF THIS WEEK.
