AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
251 PM EDT FRI AUG 3 2012

.SHORT TERM /TONIGHT THROUGH SUNDAY/...
SCATTERED SHOWERS AND TSTMS ARE DEVELOPING ALONG THE ATLANTIC
SEABREEZE ACROSS NE FL...AND IN PROXIMITY OF A WEAK MID LEVEL
TROUGH ACROSS SE GA. SMALL SCALE BOUNDARY COLLISIONS...ALONG WITH
ABUNDANT MOISTURE/INSTABILITY WILL RESULT IN ADDITIONAL STORMS
FIRING LATE THIS AFTERNOON INTO EARLY EVENING. WILL USE MID END
SCATTERED POPS FOR THIS ACTIVITY. CONVECTION WILL DISSIPATE BY
MIDNIGHT FOR MOST AREAS...WITH PERHAPS A COASTAL SHOWER OR TWO
IN THE OVERNIGHT.

A TROPICAL WAVE CURRENTLY JUST NORTH OF THE BAHAMAS WILL MOVE TO
THE WEST-NORTHWEST THROUGH SATURDAY. SOME OF THE MOISTURE FROM THE
WAVE WILL APPROACH THE AREA BY SATURDAY AFTERNOON. WITH THE WAVE
STILL TO THE SOUTH OF THE AREA...WILL KEEP POPS SCATTERED FOR
NOW...WITH THE GREATEST COVERAGE ALONG SOUTHERN PORTIONS OF THE
NE FL COAST...AND INLAND ACROSS THE REST OF NE FL AND SE GA
WITH SEABREEZE/SMALL SCALE BOUNDARY INTERACTIONS. SOME ADDITIONAL
CLOUDS...HIGHER COVERAGE...AND ONSHORE FLOW WILL KEEP TEMPERATURES
DOWN SLIGHTLY ALONG THE COAST...WITH NEAR NORMAL VALUES EXPECTED.
ANOTHER HOT DAY IN STORE INLAND...WITH LOWER TO MID 90S.

SATURDAY NIGHT AND SUNDAY...MODELS CONTINUE TO OFFER DIFFERING
SOLUTIONS WITH REGARDS TO INTENSITY...TRACK AND TIMING OF THE
TROPICAL WAVE MOVING OUT OF THE BAHAMAS. THE NAM BRINGS A WEAK BUT
CLOSED LOW INTO CENTRAL FLORIDA SATURDAY NIGHT....AND WITH
WIDESPREAD HEAVY RAINFALL POSSIBLE ON THE NORTHEAST SIDE OF THE
LOW...THIS SOLUTION WOULD BE THE WETTEST SCENARIO FOR OUR AREA. THE
UNWAVERING GFS INSISTS ON A MUCH FLATTER WAVE ACROSS SOUTHERN
FLORIDA. REGARDLESS OF THE SOLUTION...ALL MODELS SHOW DEEP
TROPICAL MOISTURE SPREADING NORTH ACROSS THE AREA. OUR LATEST
FORECAST WILL CONTINUE TO SIDE MOSTLY WITH THE GFS WITH A SLIGHT
NOD GIVEN TO THE HIGHER POPS OFFERED UP BY THE NAM. THE PRIMARY
CHANGES TO THE FORECAST WAS TO INCREASE POPS A BIT ALONG THE COAST
AND ACROSS THE SOUTH DURING THE PREDAWN HOURS EARLY SUNDAY
MORNING. SKY GRIDS WERE ALSO INCREASED TO REFLECT AN INCREASE IN
CLOUD COVER BROM SOUTHEAST TO NORTHWEST BEGINNING SATURDAY NIGHT.

CURRENT THINKING IS THAT SUNDAY WILL BEGIN WITH SCATTERED TO
NUMEROUS SHOWERS AND STORMS ALONG THE ATLANTIC COAST AND END WITH
NUMEROUS TO PERHAPS WIDESPREAD COVERAGE OVER THE INTERIOR AND
WESTERN PORTIONS OF NORTHEAST FLORIDA. MAX POPS WERE INCREASED TO
70 PERCENT ACROSS THE SOUTHWESTERN PORTIONS OF THE AREA SUNDAY
AFTERNOON. MULTILAYER CLOUDS AND INCREASED COVERAGE OF PRECIP WILL
TAME HIGHS A BIT AND HAVE LOWERED TEMPS A FEW DEGREES ON SUNDAY.
IN FACT...MANY AREAS OF NORTHEAST FLORIDA WILL LIKELY STRUGGLE TO
REACH 90. TROPICAL WAVE TO EXIT WEST INTO THE GULF BY SUNDAY NIGHT
AND PRECIP SHOULD WANE FROM EAST TO WEST DURING THE AFTERNOON.

&&

.LONG TERM...MONDAY THROUGH FRIDAY
WE WILL TRANSITION BACK TO A MORE TYPICAL SEABREEZE DOMINATED
DIURNAL THUNDERSTORM PATTERN ON MONDAY AND TUESDAY. WITH DEEP
TROPICAL MOISTURE LINGERING OVER THE AREA...COVERAGE SHOULD BE AT
LEAST SCATTERED ALONG THE MORE DOMINANT EAST COAST SEABREEZE EACH
AFTERNOON ACROSS THE INTERIOR. TEMPERATURES WILL TOP OUT IN THE
LOW 90S EACH DAY...RIGHT WHERE WE WOULD EXPECT TO BE THIS TIME OF
YEAR. THE LATEST GFS SHOWS SOME DRIER AIR WORKING IN FROM THE EAST
MID TO LATE NEXT WEEK AND THIS COULD CUT BACK ON AFTERNOON
THUNDERSTORMS A BIT...ESPECIALLY ACROSS NORTHEAST FLORIDA. WILL
RESIST LOWERING POPS UNTIL THIS BECOMES MORE CERTAIN.

&&

.AVIATION...
ATLANTIC SEABREEZE HAS ALREADY PUSHED INLAND PAST JAX...SO CRG AND
SSI FOR THE MOST PART SHOULD BE IN THE CLEAR AS FAR AS CONVECTION
IS CONCERNED THIS AFTERNOON. WILL CONTINUE WITH VCTS AT THE OTHER
3 TERMINALS...WITH GNV STANDING THE BEST CHANCE OF SEEING AN
AMENDMENT TO ADD TSRA. ANY THUNDERSTORM WILL BE CAPABLE OF BRIEF
IFR CONDITIONS IN HEAVY RAINFALL. OTHERWISE...VFR WILL PREVAIL
THROUGH TOMORROW MORNING.

&&

.MARINE...
A RIDGE OF HIGH PRESSURE OVER THE REGION WILL CONTINUE TO LIFT
NORTH OF THE WATERS THIS WEEKEND...WITH A TROPICAL WAVE CROSSING
JUST TO THE SOUTH OF THE WATERS. S/SE FLOW WILL BACK TOWARDS THE
E/SE SATURDAY INTO EARLY NEXT WEEK. EXPECT WIND SPEEDS TO REMAIN
UNDER SCEC CRITERIA...10 TO 15 KNOTS. SHOWER/TSTM COVERAGE WILL
INCREASE TO SCATTERED THIS WEEKEND AS THE WAVE MOVES OFF TO THE
WEST.

RIP CURRENTS: LOW RISK THROUGH SATURDAY.
