AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
257 PM EDT MON MAY 7 2012

...NUMEROUS SHOWERS AND EMBEDDED STORMS EXPECTED THROUGH WEDNESDAY...

...DRIER CONDITIONS EXPECTED FOR THE END OF THE WEEK...

.SHORT TERM...NOW THROUGH THURSDAY...

REST OF THIS AFTERNOON AND EVENING...VERY LITTLE STEERING FLOW HAS
ALLOWED NUMEROUS SHOWERS AND STORMS TO FIRE IN BAND OF HIGHER
MOISTURE ACROSS COASTAL NE FL AND ALL OF SE GA...WHILE AREAS ACROSS
INLAND NE FL WILL FIRE VERY SOON AS GOMEX SBRZ MOVES INLD AND RUNS
INTO OUTFLOWS FROM EARLIER CONVECTION. TEMPS HAVE TOPPED OUT MAINLY
IN THE 80S. A FEW SLOW MOVING STRONG STORMS HAVE KICKED OUT SOME
SMALL HAIL...GUSTY WINDS AND LOCALLY HEAVY RAINFALL BUT EXPECT ANY
SEVERE STORMS TO REMAIN ISOLATED.

TONIGHT...ACTIVITY IS MOSTLY DIURNALLY DRIVEN AND WILL FADE BY
MIDNIGHT WITH JUST ISOLATED SHOWERS POSSIBLE AFTER MIDNIGHT. LOWS
WILL GENERALLY BE IN THE 60S...SOME PATCHY FOG POSSIBLE BUT NOT
CONFIDENT ENOUGH TO INCLUDE IN ZFP/GRIDS.

WEDNESDAY...FAIRLY SIMILAR CONDITIONS TO TODAY WITH PRECIP WATER
LEVELS AROUND 1.50 INCHES...COOL TEMPS ALOFT ADDING TO INSTABILITY
AND WEAK STEERING FLOW. THIS WILL LEAD TO SCATTERED SHOWERS
TRIGGERED BY THE LATE MORNING HOURS BECOMING NUMEROUS SHOWERS AND
STORMS BY THE AFTERNOON HOURS. SCATTERED STRONG AND ISOLATED SEVERE
STORMS STILL POSSIBLE WITH HAIL...GUSTY WINDS AND LOCALLY HEAVY
RAINFALL DUE TO SLOW STORM MOTION. MAX TEMPS IN THE MID/UPPER 80S.

WED NIGHT/THURSDAY...LOW DEVELOPS OVER THE CAROLINAS AND TRACKS
NORTHEAST AND WILL DRAG A COLD FRONT ACROSS THE FORECAST AREA.
NUMEROUS SHOWERS AND TSTMS WED EVENING WILL BECOME MORE ISOLD/SCTD
AFTER MIDNIGHT WITH LOSS OF DAYTIME HEATING AND BY THURSDAY WILL
REALLY ONLY IMPACT PORTIONS OF NE FL SOUTH OF A LINE FROM GNV-JAX AS
THEY MAY RE-DEVELOP WITH DAYTIME HEATING.

.LONG TERM...FRIDAY THROUGH MONDAY...

FRI/SAT...SEASONABLY DRY CONDITIONS ARE EXPECTED WITH NEAR NORMAL
TEMPS IN THE 80S IN THE ONSHORE FLOW.

SUN/MON...A MOISTENING ONSHORE FLOW ALONG WITH MID LEVEL TROUGHING
WILL ALLOW FOR SCATTERED AFTERNOON/EVENING SHOWERS AND TSTMS AND
TEMPS NEAR SEASONABLE LEVELS IN THE 80S.

&&

.AVIATION...

HIGHEST CHANCES FOR THUNDERSTORMS THIS AFTERNOON WILL BE AT VQQ
AND GNV AS THE BEST COVERAGE SPREADS INLAND. GREATEST THREAT FOR
IFR IMPACTS IN HEAVY RAIN WILL BE AT GNV LATER THIS AFTERNOON. FOR
THE REMAINING TERMINALS...CONFIDENCE HAS LOWERED ENOUGH TO REMOVE
THUNDER. A BRIEF SHOWER THOUGH WILL BE POSSIBLE. A PERIOD OF LOW
CEILINGS AND VISIBILITIES WILL ONCE AGAIN BE POSSIBLE AT GNV AND
VQQ LATE TONIGHT BUT CONFIDENCE IS NOT HIGH ENOUGH TO PLACE IFR
CONDITIONS IN THE TAFS THIS FAR IN ADVANCE. MOST CONVECTION
TOMORROW WILL HOLD OFF UNTIL THE AFTERNOON...JUST BEYOND THIS TAF
PERIOD.

&&

.MARINE...

NORTHEASTERLY SURGE WILL CONTINUE TO PRODUCE 15 TO 20 KNOT WINDS
ACROSS THE GEORGIA WATERS THIS AFTERNOON AND INTO EARLY THIS
EVENING. WILL BREAK OUT THIS PORTION IN THE CWF AND GO WITH A SCEC
HEADLINE THROUGH THE EVENING HOURS. ONSHORE FLOW WILL CONTINUE
THROUGH TUESDAY...THEN WINDS WILL SHIFT BACK TO THE WEST AS AN OLD
FRONTAL BOUNDARY LIFTS BACK TO THE NORTH TUESDAY NIGHT. A COLD
FRONT WILL QUICKLY PUSH THROUGH LATE WEDNESDAY NIGHT INTO THURSDAY
MORNING AND WINDS WILL INCREASE TO 15 TO 20 KNOTS AS THEY VEER
FROM WEST TO NORTHEAST DURING THE DAY.

ASTRONOMICAL HIGH TIDES WILL RUN ABOUT A HALF FOOT TO A FOOT ABOVE
NORMAL TONIGHT AND SOME MINOR COASTAL FLOODING WILL BE POSSIBLE
ALONG THE COAST OF NORTHEAST FLORIDA AND SOUTHEAST GEORGIA AT THE
TIME OF HIGH TIDE THIS EVENING. A COASTAL FLOOD ADVISORY HAS BEEN
ISSUED TO ACCOUNT FOR THIS POSSIBILITY.

RIP CURRENTS: MODERATE RISK.
