Severe Thunderstorm Warning 50, NWS Miami, FL

SOUTH FLORIDA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI
125 PM EDT THU JUL 31 2003

SHOWERS AND THUNDERSTORMS ARE DEVELOPING ALONG THE EAST COAST SEA
BREEZE EARLY THIS AFTERNOON. THE SHOWERS AND THUNDERSTORMS SHOULD
CONTINUE TO DEVELOP ALONG THE EAST COAST SEA BREEZE...AND ALSO ALONG
THE WEST COAST SEA BREEZE AS THE AFTERNOON PROGRESSES.

THE SHOWERS AND THUNDERSTORMS WILL BE SLOW MOVERS WITH LOCALLY HEAVY
RAINFALL THIS AFTERNOON...AS THE STEERING FLOW IS STILL LIGHT OVER
SOUTH FLORIDA DUE TO HIGH PRESSURE OVER THE REGION.

THE ACTIVITY SHOULD THEN DISSIPATE THIS EVENING AS THE HEATING OF
THE DAY IS LOST. BUT A FEW ISOLATED SHOWERS AND THUNDERSTORMS COULD
DEVELOP TONIGHT OVER THE GULF WATERS AND ATLANTIC WATERS TONIGHT...
AND MOVE ONSHORE OVER THE SOUTHERN INTERIOR...WEST COAST AND THE
SOUTHEAST COAST AFTER MIDNIGHT.

THE HIGH THATS BEEN OVER SOUTH FLORIDA FOR MOST OF THE WEEK SHOULD
MOVE NORTHWARD INTO CENTRAL FLORIDA BY THIS WEEKEND...WHICH WILL
ALLOW THE REGION TO GET BACK TO MORE OF A TYPICAL SUMMER WEATHER
PATTERN. THE ONLY FLY IN THE OINTMENT IS THAT A TROPICAL WAVE EAST
OF THE BAHAMAS THAT IS INTERACTING WITH A UPPER LOW COULD BRING SOME
HIGHER MOISTURE TO THE CWA ON SUNDAY...AS THE NORTHERN PART OF THE
TROPICAL WAVE MOVES JUST TO OUR SOUTH. BUT AT THIS TIME I AM NOT
PLANNING ON CHANGING ANY OF THE POPS ON SUNDAY...AS THEY ARE ALREADY
IN THE HIGH CHANCE CAT.

.EXTENDED...

THE TROPICAL WAVE SHOULD BE WEST OF THE CWA BY MONDAY. THE HIGH OVER
THE CENTRAL FLORIDA WILL THEN MOVE SLOWLY BACK SOUTHWARD TO AROUND
LAKE OKEECHOBEE REGION BY THE MIDDLE OF NEXT WEEK...AS THE UPPER
LEVEL TROUGH OVER THE EASTERN US BUILDS SOUTHWARD INTO THE SOUTHEAST
US.

.MARINE...

CONTINUED LIGHT FLOW OF 10 KNOTS OR LESS WITH COASTAL SEA BREEZES
ALONG BOTH ATLANTIC AND GULF COASTS EACH AFTERNOON THROUGH EARLY
NEXT WEEK. SEAS SHOULD ALSO REMAIN BELOW 2 FEET ON THE WATERS
THROUGH EARLY NEXT WEEK.

.FIRE WEATHER...

NO PROBLEMS ARE ANTICIPATED AS THE RELATIVE HUMIDITIES WILL REMAIN
WELL ABOVE CRITICAL VALUES.

THANKS FOR THE COORD MLB...EYW...AND TBW.
