AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
324 PM EDT TUE AUG 23 2011

.SHORT TERM...A SURFACE TROUGH IS CURRENTLY SAGGING SOUTHWARD
ACROSS NORTHEAST FLORIDA. THIS FEATURE IS INTERACTING WITH DAYTIME
HEATING AND THE ATLANTIC SEA-BREEZE TO PRODUCE RAPIDLY FORMING
THUNDERSTORMS SOUTH OF THE I-10 CORRIDOR. ISOLATED SHOWERS WERE
NOTED ELSEWHERE ACROSS THE FORECAST AREA. SHOWERS AND STORMS WILL
CONTINUE TO FOCUS SOUTH OF THE I-10 CORRIDOR THE BALANCE OF TODAY
WITH PULSE STRONG/SEVERE THUNDERSTORMS POSSIBLE.

WEDNESDAY...A DEEPENING EASTERLY FLOW WILL INCREASE MOISTURE ACROSS
THE FORECAST AREA AND HAVE INCLUDED HOMOGENEOUS CHANCE POPS WITH
SHOWERS FOCUSING ACROSS THE EASTERN ZONES IN THE MORNING.

THURSDAY...FLOW BACKS TO THE NORTHEAST AS IRENE ADVANCES NORTHWARD...
WELL EAST OF THE FLORIDA PENINSULA. BREEZY CONDITIONS WILL LIKELY
ESTABLISH OVER THE COASTAL COUNTIES WHERE NORTHEAST WINDS WILL
SUSTAIN AROUND 15 MPH WITH GUSTS TO NEAR 25 MPH AT TIMES.
WIDESPREAD SHOWERS ALONG WITH EMBEDDED THUNDERSTORMS WILL
ESTABLISH OVER THE LOCAL COASTAL WATERS AS WELL ST. JOHNS AND
FLAGLER COUNTIES...WITH RAIN CHANCES DECREASING TOWARDS THE
NORTHWEST...WITH LOW-END CHANCE POPS FOR MUCH OF INTERIOR
SOUTHEAST GEORGIA.

FRIDAY...THE CENTER OF IRENE IS PROGGED TO POSITION WELL EAST OF THE
LOCAL AREA. A VERY LOW RISK FOR TROPICAL STORM FORCE CONDITIONS IS
NOW EXPECTED FOR THE COASTAL COUNTIES AS THE LOCAL MAINLAND IS NOW
OUT OF THE CONE OF UNCERTAINTY. AS ADVERTISED...HIGHEST POPS WILL
CONTINUE ALONG THE IMMEDIATE COAST AS SUBSIDENCE (DOWNWARD MOTION)
WILL BRING MUCH DRIER AND WARMER AIR INLAND.

GIVEN THE OFFICIAL FORECAST TRACK...MAINLY COASTAL CONCERNS ARE
ANTICIPATED WITH THIS EVENT IN THE FORM OF ROUGH SURF RESULTING IN
HIGH RIP CURRENT RISK. BEACH EROSION AND COASTAL FLOODING ARE ALSO
POSSIBLE AS TIDES WILL BE ASTRONOMICALLY HIGH.

.LONG TERM (SAT THRU TUE)...THERE MAY BE A TRAILING BAND OF MOISTURE/
SHOWERS OVER THE SOUTHERN PORTION OF THE AREA ON SATURDAY AND SUNDAY...
BUT THIS IS AGAIN SUBJECT TO CHANGE. CLIMO POPS TO RETURN EARLY
NEXT WEEK.

EXPECTING PATCHY FOG AND HAVE GONE WITH OCNL MVFR VSBY AT

CONDITIONS ARE POSSIBLE ALL LEGS BY THURSDAY NIGHT.
