AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
343 PM EDT THU JUN 26 2008

.DISCUSSION...
LATEST REFLECTIVITY IMAGERY FROM KAMX 88-D INDICATES SCATTERED
SHOWERS AND THUNDERSTORMS CURRENTLY AFFECTING PRIMARILY THE
NORTHWESTERN HALF OF THE FORECAST AREA AND ADJACENT GULF WATERS
THIS AFTERNOON. A FEW STRONG TO SEVERE THUNDERSTORMS ARE POSSIBLE
IN THIS REGION ONCE AGAIN...GIVEN STRONG INSTABILITY AND A VEERING
WIND PROFILE IN PLACE ACROSS THE AREA. OVER THE SOUTHEASTERN HALF
OF THE FORECAST AREA...MID-LEVEL SUBSIDENCE ASSOCIATED WITH AN
UPPER- LEVEL RIDGE CENTERED TO THE NORTH OF THE BAHAMAS HAS HAD A
NEGATIVE INFLUENCE ON PRECIPITATION DEVELOPMENT...AND THIS TREND
IS EXPECTED TO PERSIST THROUGHOUT THE SHORT TERM. HOWEVER...THIS
UPPER-LEVEL RIDGE IS NOT EXPECTED TO BE SUFFICIENTLY STRONG TO
PREVENT THE DEVELOPMENT OF AT LEAST SCATTERED AFTERNOON CONVECTION
ON FRIDAY AND SATURDAY...PARTICULARLY IN THE VICINITY OF GULF
COAST SEA BREEZE. MODEL POINT FORECAST SOUNDINGS CONTINUE TO
SUGGEST A WEAK NORTH TO NORTHWEST COMPONENT TO STEERING FLOW FOR
ANY ACTIVITY THAT DEVELOPS OVER SOUTH FLORIDA...AND WILL THUS
PLACE HIGHEST AFTERNOON AND EVENING POPS ACROSS THE NORTHWEST
COUNTIES...WITH PREVAILING EAST TO SOUTHEAST FLOW ALSO WARRANTING
A SLIGHT CHANCE OF NOCTURNAL SHOWERS AND STORMS ALONG THE
SOUTHEAST COAST. TEMPERATURES FROM FWC/MAV/MET MOS ALL APPEAR
REASONABLE THROUGH THE PERIOD...AND WILL MAINTAIN A PERSISTENCE
FORECAST WITH LOWS IN THE UPPER 70S/LOWER 80S AND HIGHS IN THE
UPPER 80S/LOWER 90S.

A MORE AMPLIFIED FLOW PATTERN IS STILL FORECAST BY MEDIUM RANGE
GUIDANCE TO DEVELOP ACROSS NORTH AMERICA AT THE BEGINNING OF THE
EXTENDED FORECAST PERIOD...AS RIDGING BECOMES MORE AMPLIFIED
DOWNSTREAM FROM A POWERFUL UPPER LOW DRIFTING EASTWARD OVER THE
GREAT LAKES REGION. THIS UPPER LOW WILL ULTIMATELY FORCE AXIS OF
SUBTROPICAL RIDGE OVER FLORIDA TO RETREAT EASTWARD INTO THE
ATLANTIC...WITH DEEP-LAYER MOISTURE EXPECTED TO SLOWLY INCREASE
OVER THE AREA AS SOUTHWEST FLOW DEVELOPS ALOFT. EXPECT CHANCES FOR
AFTERNOON/EVENING CONVECTION TO RETURN TO NEAR CLIMATOLOGICAL
NORMAL VALUES FOR THE ENTIRE FORECAST AREA EARLY NEXT WEEK...AND
REMAIN IN THIS RANGE THROUGH THE END OF THE FORECAST PERIOD.

&&

.MARINE...
EAST TO SOUTHEAST FLOW WILL CONTINUE ACROSS THE LOCAL COASTAL
WATERS THROUGH MUCH OF THE UPCOMING FORECAST PERIOD. EXPECT
PERIODIC WIND SURGES OF 15-20 KNOTS...BUT PREVAILING FLOW TO
GENERALLY REMAIN IN THE 10-15 KNOT RANGE ACROSS ALL OF THE LOCAL
COASTAL WATERS. SEAS WILL RANGE FROM 2-4 FEET...AND WILL ADDRESS
HIGHER WINDS WITH SCEC HEADLINE AS WARRANTED. OTHERWISE...A
MODERATE TO HIGH RISK OF RIP CURRENTS WILL CONTINUE ALONG THE
ATLANTIC COAST THROUGH THE UPCOMING WEEKEND.

&&

.FIRE WEATHER...
THERE ARE NO FIRE WEATHER RELATED CONCERNS THROUGHOUT THE FORECAST
PERIOD...WITH MINIMUM AFTERNOON RH VALUES EXPECTED TO REMAIN
ABOVE CRITICAL LEVELS.

...HIGH RISK OF RIP CURRENTS MIAMI-DADE AND BROWARD BEACHES TODAY...
...MODERATE RISK OF RIP CURRENTS PALM BEACH BEACHES TODAY...
...SOME STRONG STORMS OVER INTERIOR AREAS TODAY...
...SCATTERED STORMS EXPECTED TODAY, EXCEPT NUMEROUS NORTHERN INTERIOR AREAS...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TODAY AND TONIGHT

RIP CURRENTS: EASTERLY WINDS OF 15 TO 20 MPH WILL OCCUR ALONG THE
BEACHES OF MIAMI-DADE AND BROWARD COUNTIES TODAY, WHICH WILL LEAD
TO A HIGH RISK OF RIP CURRENTS. EASTERLY WINDS AROUND 15 MPH
ALONG THE BEACHES OF PALM BEACH COUNTY TODAY WILL LEAD TO A
MODERATE RISK OF RIP CURRENTS.

THUNDERSTORMS: SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED
TO DEVELOP OVER MAINLAND SOUTH FLORIDA ONCE AGAIN THIS AFTERNOON.
HOWEVER, A MEAN SOUTHEAST TO SOUTH STEERING FLOW WILL KEEP MOST
OF THE THUNDERSTORM ACTIVITY OVER THE INTERIOR AREAS OF SOUTH
FLORIDA TODAY.

SOME STORMS COULD BE STRONG, ESPECIALLY OVER THE NORTHERN
INTERIOR AREAS WHERE THE SEA BREEZES AND THE LAKE BREEZE SHOULD
CLASH, BUT ALL OF SOUTH FLORIDA COULD SEE A FEW STRONG STORMS
TODAY. THE PRIMARY HAZARD EXPECTED WITH THE STRONGEST STORMS WILL
BE STRONG GUSTY WINDS, FREQUENT TO EXCESSIVE LIGHTNING STRIKES,
LOCALLY HEAVY RAINFALL AND SMALL HAIL.

WIND: THE STRONGEST STORMS WILL BE CAPABLE OF PRODUCING WIND GUSTS
UP TO 60 MPH, ESPECIALLY OVER THE NORTHERN INTERIOR AREAS OF
SOUTH FLORIDA THIS AFTERNOON INTO EARLY EVENING.

HAIL: THE MID LEVELS OF THE ATMOSPHERE WILL REMAIN COOL TODAY
OVER SOUTH FLORIDA. THIS WILL ALLOW FOR THE STRONGEST STORMS TO
PRODUCE HAIL UP TO PENNY SIZE TODAY WHERE THE SEA BREEZES AND LAKE
BREEZE COLLIDE, ESPECIALLY OVER THE NORTHERN INTERIOR AREAS OF SOUTH
FLORIDA.

FLOODING:THE MOVEMENT OF ANY STORM THAT DEVELOPS TODAY WILL BE
SLOW ENOUGH TO PRODUCE LOCALLY HEAVY DOWNPOURS. THIS, IN TURN,
COULD RESULT IN PONDING OF WATER IN POORLY DRAINED LOCATIONS
ESPECIALLY OVER THE INTERIOR AREAS.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

ISOLATED TO SCATTERED AFTERNOON THUNDERSTORMS ARE EXPECTED TO
DEVELOP EACH DAY, ESPECIALLY OVER INLAND AND WEST COAST SECTIONS.
LIGHTNING STRIKES WILL BE THE PRIMARY HAZARD. ORGANIZED SEVERE
WEATHER IS NOT ANTICIPATED AT THIS TIME.

A SURFACE HIGH PRESSURE RIDGE OVER THE ATLANTIC IS EXPECTED TO
BUILD WESTWARD ACROSS CENTRAL FLORIDA. THIS WILL RESULT IN MOSTLY
EAST TO SOUTHEAST SURFACE WINDS AT 10 TO 15 MPH ALONG THE ATLANTIC
WATERS. THIS, IN TURN, WILL RESULT IN AN ELEVATED RISK OF RIP CURRENTS
THROUGH THIS PERIOD.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAYBE NEEDED ACROSS SOUTH FLORIDA THIS
AFTERNOON INTO EARLY THIS EVENING.
