AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
326 AM EDT SAT SEP 27 2014
.SHORT TERM (TODAY-SUNDAY)...
CURRENTLY AT THE SURFACE...THE TROUGH OF LOW PRESSURE APPEARS TO
STRETCH FROM NEAR BROOKSVILLE TO JUST SOUTH OF DAYTONA BEACH...WITH
ISOLATED TO SCATTERED SHOWERS SEEN IN RADAR IMAGERY ALONG THIS
FEATURE. INFRARED SATELLITE IMAGERY SHOWS WARMING CLOUD TOPS ACROSS
THE REGION...BUT PLENTY OF CONVECTIVE DEBRIS CLOUDINESS REMAINS IN
PLACE. THE MAIN SHORT TERM CONCERNS FOR TODAY REVOLVE AROUND POPS
AND THE POTENTIAL FOR ADDITIONAL FLOODING.
TODAY...
THE TROUGH OF LOW PRESSURE WILL LIFT STEADILY NORTHWESTWARD AND INTO
THE BIG BEND REGION BY THIS EVENING. MODEL GUIDANCE CONTINUES TO
SHOW A VERY MOISTURE RICH ENVIRONMENT REMAINING IN PLACE ACROSS THE
FORECAST AREA...WITH PRECIPITABLE WATER VALUES BETWEEN 2.25 AND 2.50
INCHES THROUGH THE DAY. THE MOISTURE RICH ENVIRONMENT IN COMBINATION
WITH DAYTIME HEATING SHOULD RESULT IN ANOTHER DAY WITH GOOD
SHOWER/THUNDERSTORM COVERAGE...AND WILL KEEP POPS IN THE 60-70
PERCENT RANGE. MOST OF THE CONVECTION ALLOWING MODELS SHOW A SLOW
START TO CONVECTION TODAY...AND THIS SEEMS REASONABLE GIVEN THE
CONVECTIVE DEBRIS CLOUD IN PLACE. WILL KEEP THE FORECAST RAIN FREE
IN THE MORNING...WITH ISOLATED TO SCATTERED SHOWER/THUNDERSTORM
DEVELOPMENT EXPECTED BETWEEN NOON AND 2 PM. AFTER 2 PM...COVERAGE
OF SHOWERS/STORMS SHOULD FILL IN QUICKLY WITH THE ACTIVITY
LINGERING THROUGH LATE AFTERNOON AND INTO THE EARLY EVENING HOURS.
GIVEN THE ABUNDANT MOISTURE IN PLACE ACROSS THE REGION...ANOTHER
DAY WITH LOCALLY HEAVY RAINFALL CAN BE EXPECTED IN SOME LOCATIONS.
WITH THE POTENTIAL FOR MORE HEAVY RAINS ALONG WITH RECENT HEAVY
RAINFALL RESULTING IN A REDUCTION IN RUN-OFF CAPACITY ACROSS THE
AREA...WILL KEEP THE FLOOD WATCH IN PLACE THROUGH THIS EVENING.
HIGH TEMPERATURES ARE EXPECTED TO TOP OUT IN THE UPPER 80S IN MOST
AREAS.
TONIGHT...
THE TROUGH OF LOW PRESSURE WILL CONTINUE TO LIFT NORTHWESTWARD
OVERNIGHT AND INTO THE PANHANDLE BY DAYBREAK SUNDAY. WITH PREVAILING
SOUTHEASTERLY BOUNDARY LAYER FLOW IN PLACE ACROSS THE ENTIRE
FORECAST AREA...WE SHOULD SEE SHOWERS/STORMS END IN THE EVENING WITH
ALL LAND AREAS SEEING RAIN FREE CONDITIONS BY MIDNIGHT. DRY
CONDITIONS ARE EXPECTED TO CONTINUE THROUGH THE REMAINDER OF THE
OVERNIGHT HOURS. LOW TEMPERATURES ARE EXPECTED TO BOTTOM OUT IN
THE LOW TO MID 70S.
SUNDAY...
THE TROUGH OF LOW PRESSURE WILL REMAIN ACROSS THE WESTERN FLORIDA
PANHANDLE AND COASTAL ALABAMA/MISSISSIPPI THROUGH THE DAY...WELL
TO THE NORTHWEST OF THE LOCAL AREA. THE DEEPEST MOISTURE WILL
REMAIN CLOSE TO THIS FEATURE...WITH PRECIPITABLE WATER VALUES
FALLING TO BETWEEN 2.00 AND 2.25 INCHES ACROSS THE FORECAST AREA.
WITH THE DECREASE IN COLUMN MOISTURE...MORE SUNSHINE SHOULD BE
SEEN ACROSS THE AREA AND THIS WILL AID DESTABILIZATION. WITH
PLENTY OF MOISTURE REMAINING OVERHEAD ALONG WITH MORE INSTABILITY
DUE TO INCREASING INCOMING SOLAR RADIATION...WE STILL EXPECT
FAIRLY GOOD SHOWER/THUNDERSTORM COVERAGE ACROSS THE AREA WITH POPS
RANGING FROM 50-70 PERCENT WITH THE BEST CHANCES ALONG THE WEST
FLORIDA COAST DURING THE LATE AFTERNOON AND EARLY EVENING HOURS.
HIGH TEMPERATURES ARE EXPECTED TO TOP OUT IN THE UPPER 80S NORTH
TO AROUND 90 TO THE LOWER 90S CENTRAL AND SOUTH.
&&
.LONG TERM (SUNDAY NIGHT-SATURDAY)...
THE LONG TERM PERIOD KICKS OFF ON SUNDAY NIGHT WITH A SYSTEM SLOWLY
MOVING ACROSS THE SOUTHEASTERN UNITED STATES. INCREASED MOISTURE
WILL REMAIN AROUND THE REGION THROUGH MIDWEEK WHEN A 500 MB TROUGH
MOVES THROUGH. BEHIND THE SYSTEM...SOME SLIGHTLY DRIER AIR MAY BE
ABLE TO SNEAK IN. THIS WILL BE SHORT-LIVED AS THE NEXT FRONTAL
SYSTEM APPROACHES THE REGION BY THE WEEKEND BRINGING INCREASING
MOISTURE AHEAD OF IT. THE RAINY PATTERN WILL CONTINUE...REINFORCED
BY SLOW-MOVING FRONTAL SYSTEMS AND PLENTY OF MOISTURE. TEMPERATURES
WILL REMAIN SEASONABLE...WITH NO CRISP FALL AIR TO BE EXPECTED JUST
YET IN WEST CENTRAL AND SOUTHWEST FLORIDA.
&&
.AVIATION...
SOME MVFR/IFR CIGS MAY DEVELOP AT THE KTPA...KPIE...KLAL TOWARD
DAYBREAK SATURDAY AND COULD LINGER THROUGH THE MORNING HOURS.
SCATTERED TO NUMEROUS SHRA/TSRA WITH TEMPORARY MVFR/IFR CIGS/VSBYS
ARE EXPECTED AGAIN TODAY...AND WILL HANDLE WITH VCTS FOR NOW UNTIL
TIMING BECOMES MORE CLEAR. SHRA/TSRA SHOULD END IN THE
EVENING...WITH VFR CONDITIONS THEN EXPECTED THROUGH THE REMAINDER OF
THE NIGHT.
&&
.MARINE...
A TROUGH OF LOW PRESSURE WILL LIFT NORTH OF THE WATERS TODAY AND
REMAIN OVER NORTH FLORIDA AND THE NORTHERN GULF COAST STATES THROUGH
EARLY NEXT WEEK. A FRONTAL BOUNDARY WILL THEN SAG SOUTHWARD INTO
CENTRAL FLORIDA DURING THE MIDDLE OF THE UPCOMING WORK WEEK.
OVERALL...THE PRESSURE PATTERN WILL REMAIN FAIRLY WEAK...WITH
WINDS REMAINING AT OR BELOW 15 KNOTS AND SEAS AT OR BELOW 3 FEET.
THE MAIN HAZARD THROUGH THE PERIOD WILL BE THUNDERSTORMS WHICH
WILL BE CAPABLE OF PRODUCING LOCALLY HIGHER WINDS AND SEAS.
&&
.FIRE WEATHER...
RELATIVE HUMIDITY VALUES WILL REMAIN WELL ABOVE CRITICAL LEVELS
THROUGH THE FORECAST PERIOD. PATCHY GROUND FOG WILL BE POSSIBLE
IN AREAS THAT SEE HEAVY RAINFALL...BUT NO SIGNIFICANT VISIBILITY
RESTRICTIONS ARE ANTICIPATED.
