AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
1021 AM EDT TUE MAY 16 2006

.UPDATE...WEATHER FAIRLY QUIET ACROSS SOUTH FLORIDA AT THIS
HOUR...HOWEVER...VERY ACTIVE AFTERNOON AND OVERNIGHT STILL
EXPECTED. CONVECTIVE PARAMETERS CALCULATED FROM SOUNDING THIS
MORNING A LITTLE LESS IMPRESSIVE THAN WHAT WAS GENERATED YESTERDAY
MORNING WITH INSTABILITY BEING THE REAL LIMITING FACTOR THIS TIME.
DYNAMICS OVERNIGHT PRODUCED ISOLATED SEVERE WEATHER FOR A SHORT
TIME...BUT ASSOCIATED SHORTWAVE HAS SINCE MOVED TO EAST OF THE
BAHAMAS. ANOTHER STRONGER-LOOKING SHORTWAVE IS STILL UPSTREAM AND
PRODUCING MUCH CONVECTION SOUTHWEST OF THE LOWER KEYS. THIS
ACTIVITY IS SLOWLY SPREADING NORTH/NORTHEAST. ALSO...AN OUTFLOW
BOUNDARY PRODUCED BY OVERNIGHT STORMS LIES STATIONARY ACROSS THE
STRAITS JUST SOUTH OF THE KEYS. CONVECTION ASSOCIATED WITH
APPROACHING SHORTWAVE WILL LIKELY BECOME ENHANCED AS IT INTERACTS
AND SPREADS NORTH OF THE BOUNDARY. IT REMAINS TO BE SEEN IF THIS
BOUNDARY HOLDS TOGETHER AS IT MOVES BACK NORTH GIVEN MODIFICATION
OF THE AIRMASS NORTH OF IT AS THE DAY PROGRESSES. THICKENING
CLOUDINESS SPREADING NORTHEAST AHEAD OF THIS CONVECTIVE MASS WILL
GREATLY LIMIT DIURNAL HEATING OVER THE SOUTHERN FLORIDA PENINSULA.
AN EAST COAST SEABREEZE IS STILL EXPECTED...BUT...BECAUSE OF THE
REDUCED HEATING...IT WILL LIKELY BE LATER IN THE AFTERNOON AND
CLOSER TO THE COAST THAN MONDAYS BREEZE. THEREFORE...OVERALL
CONCLUSION IS THAT STORMS WILL NOT LIKELY DEVELOP IN EARNEST OVER
SOUTH FLORIDA UNTIL AT LEAST MID AFTERNOON...BUT GREATEST THREAT
OF STRONG/SEVERE STORMS WILL BE LATE DAY INTO TONIGHT AS STRONGER
DYNAMICS AND APPROACHING COLD FRONT MOVE ACROSS THE AREA. EXPECT
HAIL THREAT TO BE LESS THAN MONDAYS...BUT SOME PENNY TO NICKEL
SIZED HAIL NOT OUT OF THE QUESTION IN DEEPEST CONVECTION.
ISOLATED DAMAGING MICROBURSTS AND/OR WEAK TORNADOES POSSIBLE.
POTENTIAL FOR SOME FLOODING EXISTS...MAINLY WHERE THE 6 TO 8
INCHES OF RAIN FELL MONDAY FROM SWEETWATER TO HIALEAH AND OPA-
LOCKA. CURRENT FORECASTS LOOK GOOD. NO BIG CHANGES ANTICIPATED AT
THIS TIME.

.PREV DISCUSSION...

..ISOLATED SEVERE THUNDERSTORMS POSSIBLE TODAY AND TONIGHT...
..LOCALLY HEAVY RAINFALL POSSIBLE AS WELL...

DISCUSSION...WATER VAPOR IMAGERY SHOWS A LARGE TROUGH OVER THE
EASTERN STATES...WITH A POTENT SHORTWAVE NOW DIGGING INTO THE
WESTERN GULF OF MEXICO. THIS SHORTWAVE WILL ROTATE EAST TOWARDS
THE FLORIDA PENINSULA THROUGH TONIGHT. AS IT DOES SO...THE LOCAL
AREA WILL REMAIN IN AN AREA OF STRONG UPPER LEVEL DIVERGENCE.
COLD FRONTAL BOUNDARY IS IN PLACE ACROSS CENTRAL FLORIDA. THIS
FRONT IS FORECAST TO SAG SOUTH INTO THE AREA BY TONIGHT...ACTING AS AN
ADDITIONAL FOCUSING MECHANISM FOR THUNDERSTORM DEVELOPMENT. ONE
COMPLEX OF STORMS TRACKED ACROSS SOUTH FLORIDA THIS MORNING...AND
SATELLITE IMAGERY SHOWS ADDITIONAL CONVECTION DEVELOPING UPSTREAM
OVER THE GULF OF MEXICO. DEEP TROPICAL MOISTURE WILL REMAIN IN
PLACE THROUGH LATE TONIGHT...WITH PRECIPITABLE WATER NEAR 2
INCHES. THUS...GIVEN THE TROPICAL AIRMASS IN PLACE ALONG WITH THE
VERY HEALTHY UPPER DYNAMICS...AM EXPECTING ROUNDS OF THUNDERSTORMS
TO CONTINUE TO AFFECT THE AREA THROUGH EARLY WEDNESDAY MORNING...UNTIL
THE COLD FRONT CLEARS THE AREA. THERE WILL CONTINUE TO BE THE POSSIBILITY
FOR ISOLATED SEVERE THUNDERSTORMS ALONG WITH LOCALLY HEAVY
RAINFALL.

WEATHER CONDITIONS WILL IMPROVE THROUGHOUT THE DAY WEDNESDAY...AS
THE FRONT EXITS THE AREA. THEN MUCH DRIER AIR WILL SETTLE INTO
SOUTH FLORIDA FOR THE LATTER PART OF THE WEEK. MOISTURE WILL BEGIN
TO MAKE A RETURN SUNDAY INTO THE EARLY PART OF NEXT WEEK...BRINGING
BACK THE POSSIBILITY FOR THUNDERSTORMS.

MARINE...WINDS WILL PREVAIL OUT OF THE SW TODAY THEN WILL BECOME
NW THEN NORTH BEHIND THE COLD FRONT WEDNESDAY INTO THURSDAY. THIS
WILL ALLOW GULF STREAM SEAS TO BUILD TO AROUND 6 FEET THEN.
OTHERWISE...MAIN CONCERN TO MARINERS WILL BE THUNDERSTORMS THROUGH
EARLY WEDNESDAY.

FIRE WEATHER...NO CONCERNS. MORE BENEFICIAL RAINFALL IS EXPECTED
THROUGH TONIGHT.

...STRONG THUNDERSTORMS POSSIBLE ACROSS SOUTH FLORIDA AGAIN TODAY...
...MODERATE FLOODING POTENTIAL FOR NORTHEAST MIAMI DADE...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS: A COLD FRONT WILL CONTINUE TO MOVE SOUTH AND THROUGH
SOUTH FLORIDA THIS EVENING. STRONG UPPER LEVEL WINDS ASSOCIATED
WITH A VIGOROUS UPPER LEVEL TROUGH COUPLED WITH LOW LEVEL
CONVERGENCE AHEAD AND ALONG THE FRONTAL BOUNDARY WILL PROVIDE
AMPLE SUPPORT FOR NUMEROUS THUNDERSTORMS ACROSS THE AREA. A FEW OF
THESE STORMS COULD BE STRONG, POSSIBLY SEVERE, WITH SMALL TO LARGE
HAIL, WIND GUSTS IN EXCESS OF 50 MPH AND ISOLATED TORNADOES
POSSIBLE. THE TIMING OF THIS ACTIVITY IS EXPECTED TO BE LATER
THIS AFTERNOON AND CONTINUE THROUGH THE EVENING AND OVER NIGHT.

TORNADOES: THE ENVIRONMENT IS SUPPORTIVE FOR PRODUCING ISOLATED
TORNADOES.

WATERSPOUTS: THE STRONGEST STORMS AS THEY MOVE ACROSS THE MARINE
AREAS, INCLUDING THE GULF COASTAL WATERS, LAKE OKEECHOBEE, AND THE
ATLANTIC WATERS WILL BE CAPABLE OF PRODUCING DANGEROUS
WATERSPOUTS.

WIND: THE STRONGEST STORMS ARE CAPABLE OF PRODUCING WIND GUSTS IN
EXCESS OF 50 MPH.

HAIL: THE STRONGEST STORMS WILL BE CAPABLE OF PRODUCING HAIL UP
THE SIZE OF DIMES, OR EVEN LARGER ALONG THE SOUTHEAST FLORIDA
COAST IF THE SEA BREEZE DEVELOPS.

FLOODING: PONDING OF WATER ON ROADS AND POORLY DRAINED AREAS IS
POSSIBLE WITH THE HEAVIEST SHOWERS AND STORMS. IF THE HEAVY RAINS
EXPECTED THIS AFTERNOON AND EVENING OCCUR, THEN MODERATE FLOODING
ALONG THE AREAS THAT RECEIVED HEAVY RAIN YESTERDAY, MOSTLY THE
NORTHEAST PORTIONS OF MIAMI DADE COUNTY, COULD RESULT IN WATER
THREATENING HOMES AND BUSINESSES IN POORLY DRAINED AREAS.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.
