AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
301 AM EDT TUE SEP 6 2011
...ANOTHER WINDY DAY WITH A HIGH RISK OF RIP CURRENTS AT AREA
BEACHES...
.SHORT TERM (TODAY THROUGH THURSDAY)...
A COLD FRONT EXTENDS SOUTH FROM A LOW OVER THE CENTRAL AL/GA
BORDER DOWN THROUGH THE PANHANDLE AND INTO THE EASTERN GULF
WATERS. DEEP MID/UPPER TROUGH CENTERED OVER THE OHIO VALLEY
REACHES DOWN INTO THE CENTRAL GULF COAST. WE'VE BEEN SEEING
ONGOING SHOWERS AND THUNDERSTORMS OVER THE WATERS AND INTO AREAS
MAINLY NORTH OF TAMPA THIS MORNING...WITH SOME ROTATION EVIDENT ON
RADAR OFFSHORE INDICATING SOME POSSIBLE WATERSPOUT ACTIVITY. WITH
THE FRONTAL BOUNDARY SLOWLY SHIFTING INTO OUR AREA
TODAY...EXPECTING GOOD COVERAGE OF STORMS WITH CORRESPONDING
BELOW NORMAL TEMPS. STORMS WILL BE MOVING RATHER QUICKLY...ABOUT
30 TO 35 MPH...BUT TRAINING OF CELLS COULD PRODUCE SOME HEAVY
RAINFALL AMOUNTS OVER ISOLATED LOCATIONS. THE CONTINUED TIGHT
GRADIENT AHEAD OF THE SURFACE BOUNDARY WILL PRODUCE GUSTY WINDS
AGAIN TODAY...BUT SHOULD MAINLY STAY BELOW ADVISORY CONDITIONS.
WILL HIGHLIGHT IN FORECAST PRODUCTS HOWEVER...AND WINDS DEFINITELY
HAVE THE POSSIBILITY OF APPROACHING SEVERE LIMITS IN AND AROUND ANY
STORMS. WITH THE CONTINUED STRONG WINDS OFFSHORE ALONG WITH HIGH
SEAS/SWELLS...WILL CONTINUE THE HIGH RISK OF RIP CURRENTS TODAY AT
AREA BEACHES. TIDES WILL RUN ABOUT 1 TO 2 FEET ABOVE NORMAL THIS
MORNING AT HIGH TIDE TIMES AS WELL. AND LASTLY...THE SOUTHWEST
WIND DIRECTION WILL BRING THE HIGHER SEAS TOWARDS THE COAST AND
THE HIGH SURF ADVISORY WILL REMAIN IN EFFECT THROUGH THIS EVENING.
AN UPPER LOW GETS CUT-OFF OVER THE TENNESSEE
VALLEY TONIGHT...SLOWLY DRIFTING NORTH AND EVENTUALLY WEST
THROUGHOUT THE SHORT TERM PERIOD. THEREFORE...WITHOUT ANYTHING TO
PUSH THE FRONTAL BOUNDARY THROUGH THE AREA...IT REMAINS OVER THE
PENINSULA THROUGH THE END OF THE WEEK. IT WILL WEAKEN TONIGHT
HOWEVER WHICH WILL ALLOW THE WINDS TO RAPIDLY DIMINISH. RAIN
CHANCES REMAIN ABOUT 40% WEDNESDAY AND THURSDAY AS THIS BOUNDARY
CONTINUES TO HANG AROUND. TEMPS ARE A BIT TRICKY. THERE IS
DEFINITELY SOME COOLER AIR BEHIND THE SURFACE BOUNDARY...BUT WILL
NOT LIKELY MAKE IT DOWN MUCH PAST NORTHERN FLORIDA. COULD SEE SOME
MID 80S OVER THE NATURE COAST WEDNESDAY AFTERNOON...AND OTHER
LOCATIONS IN THE UPPER 80S WITH AMPLE CLOUD COVER.
.LONG TERM (THURSDAY NIGHT THROUGH MONDAY)...
LONG TERM PERIOD STARTS WITH MID LVL WEAKENING TROUGHINESS STILL
IN PLACE ACROSS MUCH OF THE EASTERN HALF OF THE NATION. WEAK HIGH
PRESSURE REMAINS OVER THE EASTERN GULF REGION AND THE FL
PENINSULA WITH A DISSIPATING SFC BOUNDARY NEAR NORTHERN FL.
RELAXED PRESSURE GRADIENTS ACROSS THE REGION WILL KEEP LIGHT
WINDS WINDS IN PLACE THROUGH MONDAY.
DRIER AIR REACHES THE NORTHERN HALF OF THE STATE BEHIND THE SFC
BOUNDARY ON FRI WITH POPS DROPPING TO ISOLD/20 PERCENT ACROSS THE
NORTHERN ZONES. WILL KEEP 30 PERCENT ELSEWHERE FRI
AFTERNOON...AND SCATTERED 40 PERCENT EACH AFTERNOON THROUGH THE
WEEKEND AND MON AS MODEL SOUNDINGS AND QPF FIELDS STILL SHOW
ENOUGH THERMO/DAYTIME HEATING SUPPORT.
MODEL GUIDANCE...INCLUDING GFS...ARE NOW SUGGESTING THAT IF THERE
IS ANY TROPICAL DEVELOPMENT OVER THE SOUTHERN GULF WATERS IT WILL
LIKELY DRIFT WESTWARD AND AWAY FROM THE REGION. AFTERNOON HIGHS
REMAIN IN THE UPPER 80S TO LOWER 90S EACH AFTERNOON...AND IN THE
MID TO UPPER 70S DURING THE EARLY MORNING HOURS.
&&
.AVIATION...
BRIEF PERIODS OF MVFR WILL AFFECT TPA...PIE AND SRQ THROUGH THE
MID MORNING HOURS WITH PASSING SHOWERS AND THUNDERSTORMS. THEN IN
THE LATE MORNING AND AFTERNOON HOURS EXTENDED PERIODS OF MVFR OR
EVEN IFR ARE POSSIBLE UNDER HEAVY SHOWERS AND THUNDERSTORMS. GUSTY
WINDS ARE ALSO EXPECTED THROUGH THE LATE AFTERNOON HOURS. VFR WILL
RETURN IN THE EVENING HOURS...BUT WITH POSSIBLE PERIODS OF CIGS IN
THE 2000-4000 FEET RANGE.
&&
.MARINE...
WINDS OVER THE WATERS REMAIN WELL WITHIN ADVISORY CRITERIA THIS
MORNING WITH SEAS OFFSHORE IN THE 9 TO 11 FT RANGE. WINDS BEGIN TO
DIMINISH THIS AFTERNOON INTO THE EVENING AS THE SURFACE BOUNDARY
WEAKENS OVER THE AREA....AND SHOULD GENERALLY REMAIN AROUND 15KTS
OR LESS THROUGH THE END OF THE WORK WEEK. WITH THE WEAK SURFACE
BOUNDARY REMAINING OVER THE AREA...WIND DIRECTIONS WILL BE HIGHLY
VARIABLE WITH GENERALLY NORTH TO NORTHWEST WINDS NORTH OF TAMPA
BAY AND SOUTHWEST TO WEST WINDS SOUTH OF THE BAY.
&&
.FIRE WEATHER...
ANOTHER WINDY DAY TODAY WILL CREATE HIGH DISPERSION VALUES.
RELATIVE HUMIDITIES WILL REMAIN ABOVE CRITICAL THRESHOLDS THROUGH
THE WEEKEND.
