AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
330 AM EDT FRI APR 6 2012

...SHOWERS THIS MORNING...THEN COOLER AND DRIER FOR A CHAMBER OF
COMMERCE WEEKEND...

.SHORT TERM...TODAY THROUGH MON...
SURFACE LOW PRESSURE OVER N GA/SE SC WILL DRIFT FARTHER OVER THE
ATLANTIC EARLY THIS MORNING AS THE PARENT UPPER LEVEL TROUGH
CONTINUES TO DIG ACROSS N GA. THERE WERE SEVERAL LOW LEVEL TROUGHS
EXTENDING SOUTHWARD FROM THE SFC LOW...ONE WAS PUSHING OFFSHORE OF
THE FL ATLANTIC COAST WITH SOME SCATTERED SHOWER ACTIVITY EAST OF
THIS FEATURE OVER OUR COASTAL WATERS. TWO OTHER TROUGHS THAT WILL
AFFECT OUR AREA TODAY WERE STILL UPSTREAM...THE FIRST OVER THE FL
PANHANDLE WITH A LINE OF SHOWERS AND ISOLATED STORMS...AND THIS
CONVECTION WILL APPROACH OUR AREA EARLY THIS MORNING AFFECTING SE GA
AND OUR NORTHERN FL ZONES BEFORE SUNRISE. THE BEST CHANCE FOR
ISOLATED THUNDERSTORMS WILL BE ACROSS OUR SUWANNEE VALLEY ZONES
WHERE SFC BASED CAPES OF 600-800 J/KG MAY NOSE INLAND JUST ENOUGH
FROM THE GOMEX. STRONG STORM THREAT IS QUITE MARGINAL.

ONCE THE UPPER TROUGH LIFTS NE LATE THIS MORNING ACROSS GA AND THE
SFC LOW LIFTS NNE OFFSHORE OF THE MID-ATLANTIC REGION...YET ANOTHER
TRAILING LOW LEVEL TROUGH WILL SWING SOUTHWARD FROM THE NORTH. A FEW
SHOWERS AND SPRINKLES WILL BE POSSIBLE AS THIS SECOND TROUGH SWINGS
DOWN...WITH A NOTED INCREASE IN NLY FLOW. A WIND ADVISORY HAS BEEN
ISSUED FOR THE COAST STARTING AT 18Z TODAY...WITH A LAKE WIND FOR
CLAY AND PUTNAM COUNTIES...AS WELL AS OUR NORTHERN TIER GA ZONES
WHERE SUSTAINED WINDS OF 20 TO 25 MPH WITH GUSTS TO 35 MPH. SKIES WILL
BE PARTLY TO MOSTLY CLOUDY THIS MORNING...THEN WILL PROGRESSIVELY
CLEAR FROM THE NORTH THIS AFTERNOON TO MOSTLY CLEAR INLAND TO PARTLY
CLOUDY ALONG THE COAST. MAX TEMPS WILL RANGE FROM NEAR 70 ACROSS THE
ALTAMAHA RIVER BASIN...TO NEAR 80 ACROSS OUR SOUTH FL ZONES TOWARD
OCALA.

UPPER RIDGING TO OUR WEST WITH TROUGHING OFFSHORE WILL BRING A COOL
NNW FLOW OVER THE AREA THIS WEEKEND WITH DRY CONDITIONS AND COOLER
THAN NORMAL MIN TEMPS AS SFC HIGH PRESSURE SETTLES OVER THE AREA
FROM THE NORTH. HIGHS WILL MODERATE FROM THE MID 70S INLAND SAT TO
NEAR 80 TOWARD THE I-75 CORRIDOR. MINS WILL FALL INTO THE MID TO
UPPER 40S WELL INLAND TONIGHT THRU SUN NIGHT...WITH NEAR 60 DEG
ALONG THE COAST.

MON THE HIGH WEAKENS AND SHIFTS WEST AS A SFC TROUGH SWEEPS ACROSS
THE SEA ATLANTIC COAST. EXPECT AN INCREASE IN CLOUDS AND PERHAPS
SOME SPRINKLES. THE GFS40 SHOWS A DECENT SURGE OF MOISTURE FROM THE
WEST...BUT LOOKS A BIT BULLISH...SO WILL KEEP POPS AT < 15%.

.LONG TERM...TUE THROUGH FRI...
TUE AND WED DRY NW FLOW WILL PREVAIL AS WEAK SFC TROUGHS PASS NORTH
OF THE AREA. HIGH PRESSURE THEN BUILDS NORTH AND EAST OF THE AREA
THU AND FRI WITH SFC FLOW VEERING NE TO ESE WITH A GRADUAL INCREASE
IN MOISTURE THROUGH THE PERIOD. WILL KEEP POPS BELOW 15%. TEMPS WILL
WARM ABOVE CLIMO VALUES WITH HIGHS WARMING INTO MID/UPPER 80S BY THU
AND MINS WARMING INTO THE 50S. NO SENSIBLE WX CONCERNS EXPECTED LESS
SOME PATCHY LATE NIGHT FOG.

&&

.AVIATION...
VFR CONDS SO FAR THIS MORNING WITH A FEW SHOWERS/TSTMS POSSIBLE WITH
TRAILING FRONTAL PASSAGE BTWN 9Z-14Z AND HAVE KEPT IN VCTS IN THE
TAF FORECAST FOR NOW. REMAINDER OF THE DAY WILL BE MET WITH
INCREASING NORTH WINDS AT 15-20 KTS WITH GUSTS TO 25-30 KNOTS AT
TIMES THIS AFTERNOON AND EVENING.

&&

.MARINE...
HAVE DECIDED TO UPGRADE GALE WATCH TO A WARNING FOR THE OFFSHORE
FLOW AS N/NE FLOW INCREASES TO 20-30 KNOTS WITH FREQUENT GUSTS TO
GALE FORCE. CONFIDENCE GRIDS SUPPORTED A 50-70% CHANCE OF GALE FORCE
GUSTS FROM 18Z THIS AFTERNOON THROUGH 09Z TONIGHT. WINDS/SEAS WILL
REMAIN ELEVATED ON SATURDAY UNTIL A SLOW SUBSIDING TREND ON SUNDAY
WITH NO HEADLINES EXPECTED NEXT WEEK.

RIP CURRENTS: DEVELOPING N/NE FLOW LATE TODAY WILL ENHANCE THE
THREAT OF RIPS TO MODERATE BECOMING HIGH LATE TONIGHT AND SATURDAY
AS ONSHORE FLOW CONTINUES. BREAKERS WILL BUILD INTO THE 3-5 FT RANGE
THIS EVENING AND POSSIBLE INTO THE 5-7 FT RANGE LATE TONIGHT AND
EARLY SATURDAY AND HIGH SURF ADVISORIES MAY NEED TO BE ISSUED.

COASTAL SURF IMPACTS...ONSHORE FLOW THIS EVENING WILL RAPIDLY
INCREASE WATER LEVELS AND EXPECT HIGH TIDAL LEVELS TO APPROACH MINOR
FLOODING CRITERIA AT A FEW LOCATIONS...AND A COASTAL FLOOD ADVISORY
MAY NEED TO BE ISSUED.

&&

.FIRE WEATHER...
DRIER AIRMASS SETTLING OVER THE REGION ON SATURDAY WILL BE ENOUGH TO
TRIGGER A FIRE WEATHER WATCH ACROSS MOST OF NE FL AS RH VALUES FALL
INTO THE 25-30% RANGE WITH NE WINDS AT 10-15G20 MPH. ACROSS SE GA RH
VALUES WILL FALL INTO THE 20-25% RANGE BUT WILL NOT MEET WIND
CRITERIA.
