Area forecast discussion, Jun 21, 2:40 PM EDT, 2 hours 41 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
240 PM EDT SAT JUN 21 2008

.DISCUSSION...

AS OF EARLY THIS AFTERNOON...EAST COAST SEA BREEZE HAD MOVED
INLAND TO A LINE BISECTING METRO PALM BEACH COUNTY SOUTH TO ALONG
U.S. 27 IN BROWARD AND KROME AVE IN MIAMI-DADE. OUTSIDE OF PALM
BEACH COUNTY CONVECTION HAS BEEN SLOW TO FIRE AS ATMOSPHERE HAS
APPARENTLY STABILIZED SOME SINCE THIS MORNING...BUT ISOLATED
DEVELOPMENT WAS BEGINNING TO TAKE PLACE IN BROWARD COUNTY. WEST
COAST SEA BREEZE HAS PUSHED INLAND A GOOD WAYS WITH SCATTERED
CONVECTION FIRING ALONG IT. THINK THAT AS THE AFTERNOON WEARS ON
AT LEAST SCATTERED ACTIVITY WILL BEGIN TO FILL IN ON BOTH SEA
BREEZES WITH SLOW E/NE MOTION EXPECTED. GRADUAL INCREASE IN
ACTIVITY IS EXPECTED TOWARDS LATE AFTERNOON WITH CONVECTIVE
COVERAGE FILLING IN AS SEA BREEZES BEGIN TO CONVERGE A LITTLE WEST
OF THE EAST COAST METRO AREAS. TO THE NORTH...WIDESPREAD CIRRUS
BLOWOFF FROM CONVECTION IN CENTRAL FL COVERS MUCH OF THE LAKE
OKEECHOBEE REGION AND THIS HAS STABILIZED THINGS. HOWEVER...A
STRONG OUTFLOW BOUNDARY CONTINUES TO PRESS SOUTH FROM JUST NORTH
OF OKEECHOBEE/KOBE TO JUST NORTH OF PUNTA GORDA AND MAY FIRE
ADDITIONAL CONVECTION AS IT WORKS SOUTH INTO THESE AREAS. ONE OR
TWO STRONG STORMS STILL APPEAR POSSIBLE THIS AFTERNOON WITH GUSTY
WINDS FROM WET MICROBURSTS BEING THE MAIN THREAT ALONG WITH HEAVY
RAINFALL.

THE MEAN TROUGH WILL REMAIN IN PLACE ACROSS THE EASTERN CONUS
WITH SOUTHERN EXTENSION INTO THE NORTHERN GULF OF MEXICO TOMORROW.
AT THE SURFACE...LIGHT S/SSW FLOW WILL PREVAIL LEADING TO GOOD SEA
BREEZE DEVELOPMENT BY MID DAY ON THE EAST COAST. LIGHT WINDS WILL
LIMIT MAGNITUDE OF CONVERGENCE ALONG THE BOUNDARY UNTIL IT GETS
INLAND...SO THINK COVERAGE OF STORMS WILL BE LESS ON THE EAST
COAST TOMORROW THAN THE PAST 2 DAYS. MODEL FCST SOUNDINGS ALSO
SHOW A SLIGHT BIT OF WARMING IN THE 600-700MB LAYER AS WELL AS
SOME SLIGHT OVERALL DRYING WHICH SHOULD LIMIT COVERAGE. EXPECT AS
SEA BREEZE GETS INLAND HOWEVER THAT AT LEAST SCT THUNDERSTORMS
WILL DEVELOP AND WITH THE MEAN S/SW FLOW MIGRATE N/NE TOWARDS THE
LAKE OKEECHOBEE/PALM BEACH COUNTY AREA AND WILL HAVE HIGHEST POPS
HERE AS A RESULT.

THE UPPER TROUGH LIFTS UP THE EAST COAST A LITTLE BIT ON MONDAY
ALLOWING THE SFC-500MB RIDGE OVER THE CENTRAL ATLANTIC TO BUILD WEST
ACROSS THE FL PENINSULA. THIS WILL BRING AN INCREASING EASTERLY FLOW
REGIME BACK TO THE REGION WITH A GOOD EAST COAST SEA BREEZE STARTING
EACH DAY THROUGH MID WEEK...BUT THE FLOW WILL BE LIGHT ENOUGH FOR
WEST COAST SEA BREEZE DEVELOPMENT AND PSBL LAKE BREEZE DEVELOPMENT
AS WELL. AS A RESULT...MORE NIGHTTIME/EARLY MORNING SHOWERS OR A
STORM ARE PSBL ACROSS THE EAST COAST METRO AREAS WITH MOST AFTERNOON
ACTIVITY ACROSS THE INTERIOR AND WEST COAST...BUT GRADUALLY WARMING
MID LEVELS WILL LEAD TO LOWER OVERALL POPS MON-WED THAN WE HAVE SEEN
RECENTLY. THIS GENERAL PATTERN WILL HOLD THROUGH THE END OF THE
WEEK...WITH MODELS INDICATING ALTERNATING PERIODS OF SLIGHTLY DRIER
LOW LEVELS AND LOW LEVEL MOISTURE SURGES WHICH COULD LEAD TO SLIGHT
LOWER AND HIGHER POPS. THE GFS INDICATES WEAKER STEERING FLOW
THURSDAY AND BEYOND WHICH MAY BRING BETTER CHANCES FOR STORMS TO
EASTERN AREAS...BUT THERE IS SOME DISAGREEMENT AMONGST THE MODELS
REGARDING THIS SCENARIO.

DUE TO THE SLOW MOVEMENT OF THE THUNDERSTORMS TOMORROW...HEAVY
RAINFALL WILL REMAIN A THREAT.

&&

.AVIATION...
THUNDERSTORMS EXPECTED TO CONTINUE DEVELOPING NEAR EASTERN
TERMINALS ALONG EAST COAST SEA BREEZE THIS AFTERNOON WITH OTHER
ACTIVITY MOVING IN FROM THE WEST POSSIBLY LATER THIS
AFTERNOON/EARLY THIS EVENING. HAVE CARRIED VCTS WITH A TEMPO GROUP
AS A RESULT OF THE HEIGHTENED CHANCE FOR STORMS. SOME STORMS MAY
BE ACCOMPANIED BY BRIEF, STRONG LOW LEVEL WIND GUSTS WITH VARYING
DIRECTIONS POSSIBLE NEAR OUTFLOW BOUNDARIES.

&&

.MARINE...
LIGHT SOUTHEASTERLY WINDS WILL CONTINUE ACROSS THE LOCAL WATERS
THIS PERIOD LESS THAN 15 KNOTS WITH SEAS 3 FEET OR LESS. WINDS AND
SEAS MAY BE LOCALLY HIGHER IN AND NEAR ANY THUNDERSTORMS AND
MARINERS SHOULD EXERCISE CAUTION.

&&

.FIRE WEATHER...
NO CONCERNS AT THIS TIME AS DEWPOINTS WILL REMAIN IN THE 70S FOR
MUCH OF THIS PERIOD. SMOKE FROM THE MYAKKA CUT FIRE MAY COMBINE
WITH SOME PATCHY FOG TO CAUSE REDUCED VISIBILITIES ALONG THE
SOUTHWEST/WESTERN LAKE OKEECHOBEE SHORE COMMUNITIES TONIGHT.

...NUMEROUS THUNDERSTORMS EXPECTED TODAY WITH STRONG TO POSSIBLY
SEVERE STORMS POSSIBLE...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS: NUMEROUS THUNDERSTORMS ARE EXPECTED ACROSS MOST OF
MAINLAND SOUTH FLORIDA ONCE AGAIN TODAY. THE PRIMARY HAZARD EXPECTED
WITH THESE STORMS WILL BE STRONG GUSTY WINDS AND FREQUENT TO
EXCESSIVE LIGHTNING STRIKES.

WIND: THE STRONGEST STORMS WILL LIKELY PRODUCE WIND GUSTS FROM 50
TO 60 MPH.

HAIL: THE STRONGEST STORMS HAVE THE CAPABILITY OF PRODUCING PEA TO
DIME SIZED HAIL.

TORNADOS: THERE IS A SLIGHT RISK OF WATERSPOUTS OVER ALL MARINE
AREAS TODAY.

FLOODING: A LIGHT SOUTHWESTERLY STEERING FLOW WILL RESULT IN A
SLOW MOVEMENT OF ANY STORM THAT DEVELOPS. 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 TONIGHT.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THERE IS A CHANCE OF MAINLY AFTERNOON AND EVENING THUNDERSTORMS
ACROSS THE ENTIRE AREA THROUGH THE MIDDLE OF NEXT WEEK.
LIGHTNING STRIKES WILL BE THE PRIMARY HAZARD, WITH ORGANIZED
SEVERE WEATHER NOT ANTICIPATED AT THIS TIME.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED TODAY. PLEASE MONITOR THE SITUATION
AND AT LEAST PHONE IN REPORTS.
