WEST CENTRAL AND SOUTHWEST FLORIDA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY AREA - RUSKIN FL
200 PM EDT SAT JUL 29 2000

CURRENTLY: FAIRLY TYPICAL AFTERNOON UNDERWAY WITH SCATTERED
CONVECTION POPPING AND COLLAPSING QUICKLY ALONG THE WEST COAST SEA
BREEZE EARLY...WHILE EAST COAST SEA BREEZE AND LAKE BREEZE FROM
OKEECHOBEE MOVE SLOWLY WEST AND NORTHWESTWARD. A COLLISION WILL OCCUR
LATE AFTERNOON TO THE EAST OF INTERSTATE 75...WHERE THE BIGGEST
THREAT FOR ISOLATED PULSE SEVERE WILL OCCUR. VIL OF THE DAY LOOKS TO
BE IN THE LOW 60S AS 59 GENERATED 1/2 INCH HAIL AN HOUR AGO.

FORECAST: EVENING CONVECTION WILL GIVE WAY TO PARTLY CLOUDY SKIES
BY MIDNIGHT. MAY HAVE A FAIR AMOUNT OF CIRRUS OVERNIGHT AS UPPER
LEVEL WESTERLIES WILL BLOW THE TOP OFF ANY LAND BREEZE CONVECTION
OVER THE GULF.

SUNDAY...FAIRLY STRONG UPPER TROF PROGGED TO BE OVER THE SOUTHWEST
BAHAMAS AND THE CENTRAL CARIBBEAN. DRY AIR ON THE WEST SIDE OF THE
TROF WILL START MAKING A RUN FOR THE SOUTHEASTERN HALF OF THE FA BY
LATE IN THE DAY...BUT PROBABLY TOO LATE TO PREVENT ANOTHER ROUND OF
AFTERNOON CONVECTION OVER MOST AREAS. WILL GO 50 POPS ALL AREAS IN
A SCENARIO NOT TOO DIFFERENT FROM TODAY.

BY MONDAY...DRY AIR MENTIONED ABOVE SHOULD MAKE IT INTO THE FA...AND
SUBSIDENCE ON THE WEST SIDE OF THE TROF SHOULD BE IN PLACE. WILL
LOWER POPS...AND ALSO RAISE TEMPS TO ACCOUNT FOR MORE SUNSHINE.

MARINE: WINDS MIGHT BE A BIT STRONGER OVER THE SOUTHERN WATERS ON
MONDAY AS THE TROF MOVES CLOSER. WILL SEPARATE OUT THE AREA FROM
ENGLEWOOD SOUTH TO ACCOUNT FOR THIS.

EXTENDED: AVN LOOKS TOO WRAPPED UP WITH SYSTEM OVER WESTERN CUBA IN
72 HOURS. PREFER AN OPEN WAVE MORE LIKE THE ETA. COULD EVEN SEE THE
ENERGY SPLIT WITH SOME MOVING NORTHWARD OFF THE EAST COAST OF
FLORIDA AND MORE MOVING WESTWARD THROUGH THE YUCATAN CHANNEL SOUTH
OF US. WILL JUST KEEP A CLIMO SCENARIO FOR NOW AND WAIT FOR ANOTHER
MODEL RUN OR TWO TO SEE IF THEY FALL INTO BETTER AGREEMENT.

PRELIM NUMBERS:
TPA 75/91/75/93 3534
FMY 74/92/74/94 3534
