AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
220 PM EDT THU AUG 9 2012

.SHORT TERM...THROUGH SUNDAY
THUNDERSTORMS WILL BUILD TOWARD THE ATLANTIC COAST AND THEN
GRADUALLY FADE THIS EVENING. THEREAFTER...ONLY AN ISOLATED
THUNDERSTORM OR TWO WILL BE POSSIBLE ACROSS SOUTHEAST GEORGIA
DURING THE OVERNIGHT HOURS.

FRIDAY...TROUGHING WILL REMAIN OVER THE SOUTHEAST UNITED STATES
WHILE THE RIDGE HOLDS OVER THE FLORIDA PENINSULA. THIS PATTERN
WILL MAINTAIN A SOUTHWEST STEERING FLOW WHICH WILL RESULT IN
STORMS INITIATING OVER INLAND AREAS AND THEN TRACKING OFF TO THE
EAST DURING THE DAY. THE GREATEST COVERAGE IS EXPECTED ACROSS
SOUTHEAST GEORGIA WHERE A LINGERING BAND OF DEEP TROPICAL
MOISTURE WILL SUPPORT AT LEAST SCATTERED THUNDERSTORMS. SOME
DRIER AIR IN THE MID TO UPPER TROPOSPHERE OVER NORTHEAST FLORIDA
WILL KEEP THUNDERSTORMS MORE ISOLATED TO SCATTERED WITH A FOCUS
ALONG THE ATLANTIC SEABREEZE NEAR THE I-95 CORRIDOR LATE IN THE
AFTERNOON AND INTO THE EARLY EVENING. WITH SOME DRIER AIR
ALOFT...THE THREAT OF LOCALLY STRONG DOWNBURSTS WILL INCREASE AND
THE SPC HAS PLACED THE ENTIRE AREA WITHIN A 5% WIND THREAT
PROBABILITY. HIGHS WILL AVERAGE IN THE LOW TO MID 90S WITH THE
WARMEST READINGS EXPECTED ACROSS INLAND AREAS OF NORTHEAST
FLORIDA. HEAT INDICES WILL TOP OUT AROUND 100 DEGREES.

SATURDAY...THE LONGWAVE TROUGH WILL UNDERGO SOME AMPLIFICATION AS
A SHORTWAVE TROUGH DIGS TOWARD SOUTHEAST GEORGIA. NUMEROUS
THUNDERSTORMS WILL PUSH INTO SOUTHEAST GEORGIA AND BRING A
THREAT FOR LOCALLY HEAVY RAINFALL AND STRONG DOWNBURSTS. ALTHOUGH
LESSER COVERAGE IS EXPECTED IN NORTHEAST FLORIDA...ISOLATED TO
WIDELY SCATTERED SHOWERS AND STORMS WILL BUILD TOWARD THE EAST
COAST WITH ENHANCEMENT EXPECTED ALONG THE ATLANTIC COAST SEABREEZE
NEAR THE I-95 CORRIDOR LATE IN THE AFTERNOON.

SUNDAY...RAIN CHANCES WILL FINALLY LOWER ACROSS SOUTHEAST GEORGIA
BEHIND THE DEPARTING SHORTWAVE. ONLY ISOLATED TO WIDELY SCATTERED
STORMS EXPECTED ON SUNDAY WITH TEMPS TOPPING OUT IN THE MID 90S
INLAND.

&&

.LONG TERM...MONDAY THROUGH THURSDAY
DE-AMPLIFICATION OF UPPER TROUGH AND DRY AIR INFILTRATION ALOFT
WILL LEAD TO DECREASING RAIN CHANCES AND SLIGHTLY HOTTER
TEMPERATURES. POPS WILL DROP DOWN TO AROUND 20 TO 30
PERCENT...MAINLY TO ACCOUNT FOR A FEW THUNDERSTORMS WITH THE
AFTERNOON SEABREEZES. EXTRA INSOLATION WILL LIKELY PUSH MAX TEMPS
UP INTO THE MID 90S WITH HEAT INDICES OVER 100 DEGREES.

&&

.AVIATION...HAVE TEMPO TSRA IN TAFS UNTIL 21Z...AND TIL 22Z FOR SSI
AS STORMS WILL CONTINUE TO DEVELOP AND MOVE TOWARDS THE EAST COAST.
HAVE VCTS TIL 01Z AT SSI WITH STORMS DISSIPATING BEFORE OR AROUND
THAT TIME.

&&

.MARINE...SOUTHWEST WINDS WILL CONTINUE OVER THE WATERS THE NEXT FEW
DAYS AS SURFACE RIDGE REMAINS TO THE SOUTH AND TROUGHING TO THE
NORTH. NOCTURNAL SURGES WILL INCREASE WINDS TO AROUND 15 KNOTS WITH
POSSIBLE SCEC HEADLINES NEEDED FOR OFFSHORE ZONE. SEAS WILL BE
MOSTLY IN 2 TO 4 FOOT RANGE.

RIP CURRENTS: LOW RISK AS OFFSHORE FLOW DOMINATES.
