The radar

The Miami radar (KAMX), 27 km from the middle of the area, began a volume at 18:24 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, 6.4 hours before the alert went out and 43 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 Jul 2, 10:15 AM EDT, 4 hours 6 minutes earlier.

Area forecast discussion, Jul 2, 10:15 AM EDT, 4 hours 6 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MIAMI FL
1015 AM EDT WED JUL 2 2008

.UPDATE...NO CHANGES PLANNED FOR THE CURRENT FORECAST PACKAGE AT
THIS TIME. TODAYS WEATHER PROMISES TO BE RATHER SIMILAR TO
YESTERDAYS (TUE). 12Z SOUNDING ALMOST IDENTICAL TO 24 HRS AGO WITH
PW = 1.82 INCHES, LI = 7.9. THE ONLY DIFFERENCE (AND NOT
SIGNIFICANT) IS A SLIGHTLY HIGHER CAPE AND SLIGHTLY FASTER STEERING
FLOW. ALSO , RUC80 STREAMLINE ANALYSIS SHOW UPPER LEVEL DIFFLUENCE
OVER THE LOCAL AREA AND WEAK CONVERGENCE AT THE LOW LVL THAT COULD
EASILY BE ENHANCED BY SEA BREEZES LATER ON. THEREFORE, AFTERNOON
TSTMS IS PRACTICALLY A SURE THING, AND AGAIN, ONCE THEY DEVELOP,
THEY WILL MOVE NORTHEASTWARD UNDER THE SOUTHWEST STEERING FLOW.
AGAIN, LOCATION OF INITIAL CONVECTION WILL DEPEND GREATLY ON SEA
BREEZES INTERACTION. A FEW OF THE STORMS COULD BECOME STRONG WITH
WIND GUSTS TO 40 MPH, FREQUENT TO EXCESSIVE LIGHTNING AND SMALL
HAIL. HEAVY DOWNPOURS CAN ALSO BE EXPECTED DUE TO THE SLOW MOVEMENT
OF THE STORMS.

.AVIATION...
ACTIVE CONVECTION ACROSS THE REGION IS EXPECTED TODAY...BUT MAINLY
IN THE EARLY AFTERNOON INTO THE EVENING. LINGERING MOISTURE ACROSS
THE REGION AND A MID TO UPPER LEVEL TROUGH IN THE CENTRAL GULF
WILL RESULT IN CONDITIONS FAVORABLE FOR CONVECTION. WHILE LIGHT
SOUTHEAST FLOW WILL FAVOR CONVECTION IN THE INTERIOR AND WEST OF
THE PENINSULA...WESTERLY FLOW IN THE LOWER LEVELS THROUGH THE
UPPER LEVELS SHOULD RESULT IN CONVECTION ACROSS THE EAST COAST
AS WELL. PERIODS OF MVFR CONDITIONS EXPECTED IN THE AFTERNOON
THROUGH THE EVENING AND BRIEFER PERIODS OF IFR CONDITIONS POSSIBLE
ACROSS ALL SOUTH FLORIDA TERMINALS IN THIS TIME.

60

&&

.PREV DISCUSSION... /ISSUED 340 AM EDT WED JUL 2 2008/

DISCUSSION...
NOT MUCH CHANGE TO THE SHORT TERM FORECAST REASONING FOR TODAY.
THE TAIL END OF THE EASTERN CONUS TROUGH CONTINUES TO LINGER IN
THE EASTERN GULF OF MEXICO WITH SOUTHWESTERLY STEERING FLOW IN THE
MID LEVELS ACROSS SOUTH FL ON THE EAST SIDE OF IT. MODELS CONTINUE
TO INDICATE GOOD UPPER DIVERGENCE AHEAD OF THIS FEATURE TODAY.
MODEL FORECAST SOUNDINGS DO SHOW A SLIGHT WARMING IN THE MID-
LEVELS TODAY...BUT GIVEN THE PROXIMITY OF THE TROUGH AND THE TEMPS
ON THE 00Z MIAMI SOUNDING THIS MAY BE IN ERROR. THUS...EXPECTING A
DAY SIMILAR TO YESTERDAY WITH BOTH SEA BREEZES FIRING ACTIVITY
CLOSER TO THE COASTS...WITH ACTIVITY MOVING SLOWLY NORTHEAST
TOWARDS PALM BEACH COUNTY...AND THEN OTHER ACTIVITY CONGEALING IN
THE INTERIOR AND MOVING SLOWLY NORTHEAST AGAIN. HEAVY RAIN AND
ISOLATED STRONG STORMS WITH SMALL HAIL AND GUSTY WINDS WILL BE
POSSIBLE AGAIN TODAY.

EXPECT MOST ACTIVITY TO DIE DOWN DURING THE MID EVENING HOURS ONCE
AGAIN...BUT AT LEAST ISOLATED STORMS COULD CONTINUE ACROSS THE
LOCAL WATERS AND EAST COAST METRO AREAS ALL NIGHT GIVEN PRESENCE
OF THE TROUGH AND LIGHT ESE SFC FLOW.

MODELS HAVE CONTINUED TO TREND AWAY FROM THE LARGE, DEEP-LAYERED
ATLANTIC RIDGE BUILDING BACK ACROSS FL LATE THIS WEEK AND THIS
WEEKEND. INSTEAD...MOST GUIDANCE NOW INDICATES A WEAKNESS IN THE
RIDGE WILL REMAIN OVER THE EASTERN GULF OF MEXICO WITH EVEN WEAK
TROUGHING LINGERING FROM 500-250MB. SFC RIDGE AXIS WILL REMAIN
ACROSS NORTH CENTRAL FL THIS PERIOD WITH LIGHT ESE SFC FLOW AND
DAILY WEST COAST SEA BREEZES COMBINED WITH SW STEERING FLOW IN THE
MID/UPPER LEVELS AND PWATS REMAINING HIGH. THE RESULT IS A WETTER
PATTERN FOR SOUTH FL...ESPECIALLY THE EASTERN HALF WHERE IT LOOKED
TO BE TRENDING DRIER THIS PERIOD JUST A FEW DAYS AGO.

BY SUNDAY INTO EARLY NEXT WEEK...GFS FINALLY BUILDS THE MID-LEVEL
RIDGE IN SOME...LEADING TO DEEP-LAYERED SSE FLOW ACROSS SOUTH FL.
MODEL FCST SOUNDINGS THIS PERIOD INDICATE A SLIGHT INCREASE IN
OVERALL STABILITY OF THE ATMOSPHERE...BUT ALSO PERIODIC MOISTURE
SURGES OUT OF THE CARIBBEAN WITH PWATS MOSTLY 2 INCHES OR ABOVE.
THIS WILL CONTINUE MORE CONVECTIVE COVERAGE POSSIBLY CONTINUING
ABOVE CLIMO VALUES THIS PERIOD.

MARINE...
ESE TO SE WINDS 15 KTS OR LESS WITH SEAS 4 FT OR LESS OUTSIDE OF
THUNDERSTORM ACTIVITY THIS PERIOD. RISK OF WATERSPOUTS AGAIN
TODAY, ESPECIALLY THE ATLANTIC WATERS.

FIRE WEATHER...
NO CONCERNS AS MOISTURE LEVELS REMAIN AROUND NORMAL FOR THIS TIME
OF YEAR.

FREQUENT CLOUD TO GROUND LIGHTNING AND GUSTY WINDS WHICH WILL BE
ACCOMPANIED BY LOCALLY HEAVY RAINFALL.

WATERSPOUTS: WITH WEAK SOUTHWEST STEERING FLOW, ANY BOUNDARIES
OVER THE AREA WATERS WILL PRODUCE A SLIGHT RISK OF WATERSPOUTS
TODAY.

WIND:THE STRONGEST THUNDERSTORMS TODAY WILL HAVE THE POTENTIAL TO
PRODUCE WIND GUSTS UP TO 40 MPH.

FLOODING: THERE IS A SLIGHT RISK OF LOCAL URBAN TYPE FLOODING OF
ROADWAYS AND LOW LYING AREAS DUE TO SLOW MOVING THUNDERSTORMS
TODAY.

HAIL: THERE IS A SLIGHT RISK OF SMALL HAIL OCCURRING WITH THE
THUNDERSTORMS EXPECTED ACROSS THE REGION TODAY.

THE STEERING PATTERN WILL CONTINUE FROM THE SOUTHWEST, BRINGING
HIGHER CHANCES FOR THUNDERSTORMS TO THE EAST COAST METRO AREAS
THURSDAY AND POSSIBLY INTO THE WEEKEND.

A LIGHTER WIND FLOW AND CONVERGENCE OVER THE AREAS WATERS COULD
LEAD TO AN OCCURRENCE OF WATERSPOUT ACTIVITY THROUGH THURSDAY.
