Severe Thunderstorm Warning 47, NWS Miami, FL

SOUTH FLORIDA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI
110 PM EDT TUE JUL 29 2003

UPPER LEVEL LOW THAT WAS OVER CENTRAL CUBA YESTERDAY HAS OPENED UP
INTO A TROUGH OF LOW PRESSURE OVER THE REGION EARLY THIS
AFTERNOON...AS THE HIGH PRESSURE AT THE SURFACE MOVED INTO THE CWA
FROM CENTRAL FLORIDA.

SHOWERS AND THUNDERSTORMS WERE STARTING TO DEVELOP ALONG THE EAST
COAST SEA BREEZE EARLY THIS AFTERNOON...AND SHOULD CONTINUE TO
DEVELOP THROUGH THE AFTERNOON AND MOVE SLOWLY INLAND. OTHER SHOWERS
AND THUNDERSTORMS SHOULD ALSO DEVELOP ALONG THE WEST COAST SEA
BREEZE LATER THIS AFTERNOON AND MOVE SLOWLY INLAND.

THE SHOWERS AND THUNDERSTORMS THAT DO DEVELOP WILL HAVE LOCALLY
HEAVY RAINFALL...AS THE STEERING FLOW WILL BE LIGHT DUE TO THE HIGH
OVER THE REGION. A FEW THUNDERSTORMS COULD ALSO APPROACH THE STRONG
SIDE LATE THIS AFTERNOON WERE THE SEA BREEZES COLLIDE...AS THE MID
LEVELS HAVE COOL A LITTLE DUE TO THE THROUGH OVER THE REGION.

THE ACTIVITY SHOULD THEN DIED OUT THIS EVENING AS THE HEATING OF THE
DAY IS LOSS. A FEW SHOWERS AND THUNDERSTORMS COULD AFFECT THE WEST
COAST AND THE SOUTHEAST COAST AFTER MIDNIGHT...AS SOME OF THE
SHOWERS AND THUNDERSTORMS OVER THE ATLANTIC AND GULF WATERS COULD
MOVE ONSHORE ON A SOUTH TO SOUTHEAST WIND DIRECTION.

THE HIGH WILL THEN MOVE SLOWLY NORTHWARD TO CENTRAL FLORIDA THROUGH
FRIDAY...AS THE UPPER LEVEL TROUGH WEAKENS. THIS WILL ALLOW THE
WINDS TO BECOME SOUTHEAST ON WEDNESDAY AND REMAIN SOUTHEAST THROUGH
FRIDAY. SO WE SHOULD GET BACK TO A MORE TYPICAL SUMMER PATTERN ON
WEDNESDAY AND REMAIN THAT WAY THROUGH FRIDAY.

.EXTENDED...

THE HIGH WILL REMAIN OVER THE CENTRAL FLORIDA THROUGH THE WEEKEND
BEFORE MOVING BACK OVER SOUTH FLORIDA EARLY NEXT WEEK...AS THE UPPER
TROUGH OVER THE EASTERN US DEEPENS INTO THE SOUTHEAST. THIS WILL
ALLOW SOUTH FLORIDA TO REMAIN IN THE SUMMER PATTERN THROUGH THE
WEEKEND BEFORE THE CHANCE OF SHOWERS AND THUNDERSTORMS INCREASE
EARLY NEXT WEEK.

.MARINE...

THE WINDS WILL REMAIN LESS THAN 10 KNOTS THROUGH THE WEEKEND OUT OF
THE SOUTHEAST AFTER TONIGHT. TONIGHT THE WIND WILL BE OUT OF THE
SOUTH TO SOUTHEAST LESS THAN 10 KNOTS.

.FIRE WEATHER...

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