WEST CENTRAL AND SOUTHWEST FLORIDA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY AREA - RUSKIN FL
110 PM EDT FRI JUN 4 2004

.SHORT TERM (TONIGHT THRU SUNDAY)...AN UPPER TROUGH WITH WEAK VORT
LOBES MOVING THROUGH ITS BASE WILL PERSIST OVER THE SERN U.S. AND
FLORIDA THROUGH THE PERIOD. AT THE SURFACE HIGH PRESSURE ACROSS THE
SOUTHERN PENINSULA WILL GRADUALLY DRIFT NORTH BY SUNDAY BECOMING
ALIGNED SE-NW ACROSS THE N-CENTRAL PENINSULA. COMBINATION OF AMPLE
LOW LEVEL MOISTURE...INSTABILITY AND DAILY AFTERNOON SEA BREEZE
CIRCULATIONS WILL SUPPORT SCATTERED SHOWERS AND THUNDERSTORMS BOTH
DAYS...AND WILL BLANKET THE FORECAST AREA WITH POPS IN THE 40-50%
RANGE. LIGHT STEERING FLOW ON SATURDAY WILL AGAIN ALLOW STORMS TO
PROPAGATE ALONG THE SEA BREEZE BOUNDARIES WITH SOME LOCALLY HEAVY
RAINFALL POSSIBLE.

ON SUNDAY STEERING FLOW WILL BECOME SOUTHEASTERLY AS THE SURFACE
RIDGE DRIFTS A BIT FURTHER NORTH...WITH BEST COVERAGE OF CONVECTION
SETTING UP ALONG COASTAL LOCATIONS DURING THE LATE AFTERNOON AND
EARLY EVENING HOURS. INCREASED CLOUD COVER AND HIGHER PRECIP CHANCES
WILL KEEP TEMPERATURES NEAR CLIMO-LEVELS THROUGH THE WEEKEND. MAV/MET
GUIDANCE IS AGAIN CLOSE...SO WILL USE A BLEND.

.LONG TERM (SUN NIGHT-FRI)...UPPER RIDGING TO BUILD OVER THE AREA SUN
NIGHT AND BECOME WELL ESTABLISHED BY MID WEEK. SFC RIDGE AXIS MOVES
OVER N FL/S GA KEEPING THE AREA IN SE LL FLOW WITH PLENTY OF
ATLANTIC MOISTURE IN PLACE TO COMBINE WITH DIURNAL HEATING TO PRODUCE
AFTERNOON WEST COAST SEABREEZE CONVECTION THAT WILL LATER COLLIDE
WITH EAST COAST SEA BREEZE AND OUT FLOW BOUNDARIES FOR SCATTERED
AFTERNOON INTO EVENING SHOWERS AND THUNDERSTORMS. LATEST EXT MODELS
TRY TO SPIN UP UPPER AND SFC LOW IN WESTERN GULF LATE IN THE PERIOD
AND MOVE IT INTO THE NORTH CENTRAL GULF. SFC GRADIENT WOULD TIGHTEN
WITH INCREASING CHANCES FOR PRECIP AHEAD OF SYSTEM. WILL KEEP SCT
POPS ATTM AND WAIT TO SEE BETTER MODEL CONTINUITY. TEMPS NEAR NORMAL.

SOUTH TO SOUTHWEST WIND FLOW IN THE 5 TO 10 KNOT RANGE CAN BE
EXPECTED TONIGHT AND SATURDAY. WINDS WILL BACK TO THE SOUTH AND
SOUTHEAST SUNDAY AND INTO EARLY NEXT WEEK AS SURFACE HIGH PRESSURE
SETS UP OVER THE NORTH-CENTRAL PENINSULA. NO HIGHLIGHTS EXPECTED AT
THIS TIME...BUT HIGHER WIND AND SEAS WILL BE POSSIBLE IN THE VICINITY
OF LATE AFTERNOON AND EVENING THUNDERSTORMS EACH DAY.

&&

5 AM EDT FRI JUN 4 2004

THIS HAZARDOUS WEATHER OUTLOOK IS FOR WEST CENTRAL AND SOUTHWEST
FLORIDA.

.DAY ONE...TODAY:

...ISOLATED STRONG TO SEVERE THUNDERSTORMS POSSIBLE TODAY...

THE COMBINATION OF AN UPPER LEVEL DISTURBANCE...AND A
MOIST...UNSTABLE ATMOSPHERE...WILL LEAD TO SCATTERED SHOWERS AND
THUNDERSTORMS AGAIN THIS AFTERNOON AND EVENING...ESPECIALLY
INLAND...AWAY FROM THE GULF COAST.

ISOLATED SHOWERS AND THUNDERSTORMS COULD DEVELOP AS EARLY AS THIS
MORNING OVER THE EASTERN GULF WATERS...AND IMMEDIATE COASTAL COUNTIES
FROM THE TAMPA BAY AREA...NORTHWARD TO CEDAR KEY.

BY THIS AFTERNOON...SHOWERS AND THUNDERSTORMS ARE EXPECTED TO BECOME
MORE NUMEROUS AS THE WEST COAST SEA BREEZE HELPS TO PUSH THE STORMS
EASTWARD TOWARD THE INLAND COUNTIES.

SOME STORMS COULD BECOME STRONG OR SEVERE THIS AFTERNOON...
ESPECIALLY INLAND.

THE MAIN THREATS WITH ANY STRONG TO POSSIBLY SEVERE THUNDERSTORMS
WILL BE DAMAGING WIND AND SMALL HAIL.

STAY TUNED TO NOAA WEATHER RADIO OR YOUR LOCAL MEDIA OUTLETS FOR
POSSIBLE WATCHES OR WARNINGS THIS AFTERNOON.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY:

SCATTERED AFTERNOON AND EVENING THUNDERSTORMS ARE AGAIN EXPECTED FOR
SATURDAY...ESPECIALLY OVER INLAND LOCATIONS. SOME STORMS COULD BECOME
STRONG. BY SUNDAY...LOW LEVEL WINDS ARE EXPECTED TO BECOME
SOUTHEASTERLY...AND CONTINUE FROM THE SOUTHEAST THROUGH MUCH OF NEXT
WEEK. THE LOW LEVEL SOUTHEAST WINDS WILL SHIFT THE BEST CHANCES FOR
SCATTERED AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS TOWARD THE
GULF COAST...WHICH WILL ALSO BE WHERE THE HIGHEST THREAT FOR ISOLATED
STRONG TO SEVERE THUNDERSTORMS WILL BE EACH DAY.

.SPOTTER CALL TO ACTION STATEMENT...
