AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
152 PM EDT TUE AUG 5 2008

...WARMER CONDITIONS EXPECTED EAST COAST AREAS THIS WEEKEND INTO
EARLY NEXT WEEK...

.DISCUSSION...
THE EAST AND WEST COAST SEA BREEZES WERE DEVELOPING OVER BOTH METRO
AREAS OF SOUTH FLORIDA EARLY THIS AFTERNOON. THE EAST COAST SEA
BREEZE WILL CONTINUE TO PUSH ACROSS THE CWA THIS AFTERNOON...WHILE
THE WEST COAST SEA BREEZE REMAINS OVER THE WEST COAST METRO AREAS.

SHOWERS AND THUNDERSTORMS WERE ALSO STARTING TO DEVELOP ALONG BOTH
THE EAST AND WEST COAST SEA BREEZES EARLY THIS AFTERNOON...AND SHOULD
CONTINUE TO DEVELOP THROUGH THE AFTERNOON HOURS. THERE WAS ALSO
SOME SHOWERS AND A FEW THUNDERSTORMS OVER THE ATLANTIC WATERS EARLY
THIS AFTERNOON WHICH COULD WORK INTO THE EAST COAST METRO AREAS
THROUGH THE AFTERNOON HOURS. SO WILL CONTINUE WITH THE NUMEROUS POPS
OVER THE INTERIOR AND WEST COAST AREAS EARLY THIS AFTERNOON...AND
KEEP SCATTERED POPS OVER THE EAST COAST AREAS.

THE SHOWERS AND THUNDERSTORMS SHOULD DISSIPATE THIS EVENING OVER
MOST OF THE CWA AS THE HEATING OF THE DAY IS LOST. HOWEVER...THE
EAST COAST METRO AREAS COULD STILL SEE A FEW SHOWER OR
THUNDERSTORMS TONIGHT...DUE TO THE EASTERLY WINDS COMING OVER THE
AREA AROUND HIGH PRESSURE OVER NORTHERN FLORIDA. SO WILL END THE
SHOWER AND THUNDERSTORM ACTIVITY OVER THE INTERIOR AND WEST COAST
AREAS THIS EVENING...BUT KEEP A SLIGHT CHANCE GOING ALONG THE EAST
COAST AREAS TONIGHT.

THE HIGH WILL REMAIN NEARLY STATIONARY ON WEDNESDAY BEFORE GETTING
PUSH SOUTH INTO THE CWA LATE THIS WEEK...AS A UNUSUALLY DEEP TROUGH
OF LOW PRESSURE DEVELOPS OVER THE EASTERN UNITED STATES. THIS WILL
ALLOW FOR THE WINDS TO SWING FROM A EASTERLY DIRECTION ON WEDNESDAY
TO A SOUTHERLY DIRECTION LATE THIS WEEK OVER SOUTH FLORIDA...AND
SHIFT THE HIGHEST POPS FROM THE WEST COAST AREAS ON WEDNESDAY TO
AROUND LAKE OKEECHOBEE AREA LATE THIS WEEK.

.EXTENDED FORECAST...
THE HIGH WILL CONTINUE TO MOVE SOUTH INTO THE FLORIDA KEYS THIS
WEEKEND INTO EARLY NEXT WEEK...AS THE DEEP TROUGH OF LOW PRESSURE
CONTINUE TO DEEPEN OVER THE EASTERN UNITED STATES PUSHING A
SURFACE FRONTAL TROUGH INTO NORTH CENTRAL FLORIDA. THIS WILL KEEP
SOUTH FLORIDA IN A SOUTHWEST STEERING FLOW THIS WEEKEND INTO EARLY
NEXT WEEK ALLOWING FOR THE HIGHEST POPS TO BE OVER THE EASTERN
METRO AREAS THIS WEEKEND INTO EARLY NEXT WEEK.

THIS WILL ALSO ALLOW FOR ABOVE NORMAL HIGH TEMPERATURES IN THE MID
90S TO AFFECT THE EAST COAST METRO AREAS THIS WEEKEND INTO EARLY
NEXT WEEK.

&&

.MARINE...
THE WIND DIRECTION WILL SWING FROM A EASTERLY DIRECTION ON
WEDNESDAY TO A SOUTHWEST DIRECTION BY THIS WEEKEND OVER ALL OF
SOUTH FLORIDA WATERS. THE SPEEDS WILL REMAIN BELOW 10 KNOTS
THROUGH THE WEEKEND. THEREFORE...THE SEAS WILL REMAIN BELOW 2 FEET
THIS WEEK INTO THIS WEEKEND FOR THE ATLANTIC AND GULF WATERS.

SO MARINERS CAN EXPECT GOOD BOATING WEATHER OUTSIDE OF THE SHOWERS
AND THUNDERSTORMS FOR THIS WEEK INTO THIS WEEKEND.

&&

.FIRE WEATHER...
THE RELATIVE HUMIDITIES WILL REMAIN ABOVE THE 35 PERCENT CRITICAL
VALUE THROUGH THE WEEK INTO THE WEEKEND. SO NO PROBLEMS WITH THE
FIRE WEATHER PRODUCTS.
