AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
150 PM EDT WED AUG 3 2005

.SHORT TERM...COMPLEX WX PATTERN CONTINUES WITH SOME VARIETY OF
SHEAR AXIS PRESENT FROM THE SURFACE TO THE MID LEVELS OF THE
ATMOSPHERE. THIS...ALONG WITH THE SEABREEZE...IS PROVIDING AN
ABUNDANCE OF FOCUSING MECHANISMS FOR CONVECTION. PLENTY OF
INSTABILITY WITH NO CIN PRESENT IS RESULTING IN WIDESPREAD WEAK
STORM FORMATION. EXPECT FOR THE REMAINDER OF THE EVENING...BEST
CONCENTRATION OF STORMS WILL BE IN THE WESTERN PORTIONS OF THE
GEORGIA FORECAST AREA WHERE STEERING FLOW IS EASTERLY TO THE
EASTERN SECTIONS OF THE FLORIDA ZONES WHERE THE FLOW IS MORE
WESTERLY. EAST TO NORTHEAST PUNCH OVER THE GEORGIA ZONES SHOULD
ALLOW SOME OF THE DRIER AIR NOTED NORTH OF THE CWA TO MAKE ITS WAY
SOUTHWARD ALONG THE GEORGIA COAST.

BIGGEST QUESTION FOR THE SHORT TERM IS WILL THIS DRY AIR CONTINUE
ITS MARCH THROUGH THE AREA OR SHIFT BACK NORTH AS THE GFS SUGGEST.
I HAVE SEEN MY SHARE OF MODEL DISCREPANCIES...BUT THIS IS A BIG ONE
WITH POPS SPREAD BY SOME 70 TO 80 PERCENT FOR THURSDAY AND FRIDAY.
PROBLEM HAS BEEN THERE IS REALLY NOT TOO MUCH IN THE ANALYSIS THAT
WOULD ALLOW ME TO HEAVILY FAVOR ONE MODEL OVER ANOTHER. I DO NOTE
FROM THE RUC ANALYSIS THAT THERE IS SOME DRY AIR TO THE NORTH OF
THE CWA AND MORE IN LINE WITH THE NAM...BUT GFS HAS DONE A BETTER
JOB WITH PRECIP COVERAGE THUS FAR THIS AFTERNOON. LOOKING AT THE
NAM...IT DOES SEEM TO DRY OUT THE AIRMASS QUICKLY FOR NO APPARENT
REASON IN ADDITION TO THE ADVECTIVE COMPONENT IT IS SHOWING. WOULD
TEND TO LEAN TOWARD THE WETTER GFS BASED ON RECENT TRENDS OF THE NAM
TO BE TOO AGGRESSIVE WITH THESE DRY FEATURES...BUT SIMPLY CANNOT GO
WITH THE 70 AND 80 POPS SHOWN BY THE GFS WHEN THE ETA SHOWS NEAR
20. THEREFORE...AM PLANNING ON USING A BLEND AND HAVING A STEEP
GRADIENT FROM NORTHEAST TO SOUTHWEST INDICATING AT LEAST SOME DRY
AIR WORKING IN FROM THE NORTH. HOPEFULLY MODELS WILL COME INTO
BETTER AGREEMENT FOR THE MORNING PACKAGE.

AS MENTIONED...THESE LARGE DISCREPANCIES CONTINUE RIGHT INTO THE
FIRST HAVE OF THE WEEKEND WITH THE NAM DRYING THE ATMOSPHERE OUT
ENOUGH TO HAVE NIL POPS OVER THE AREA. WILL AGAIN USE A BLEND BUT
HAVE A DEFINITE DOWNWARD TREND IN THE POPS THROUGH SATURDAY.

.LONG TERM...GFS FORMS LOW PRESSURE OVER THE DEEP SOUTH THE LATTER
HALF OF THE WEEKEND. WILL STAY AWAY FROM THIS SOLUTION FOR NOW AND
STAY WITH THE MORE CONSERVATIVE NAM WITH NEAR CLIMO POPS AND TEMPS.

&&

.MARINE...NNE FLOW CONTINUES OVER THE WATERS THIS AFTERNOON BETWEEN
LOW PRESSURE OFFSHORE OF THE SE COAST AND HIGH PRESSURE OVER THE NE
CONUS. MODELS ARE NOT REALLY INDICATING MUCH OF A SURGE...BUT BUOYS
REPORT WINDS 10-15 GUSTS TO NEAR 20 KT AT TIMES OVER SC AND GA
WATERS. SEAS ARE RUNNING 2-4 FT. WILL INCREASE WINDS THIS EVENING TO
10-15 KTS...THEN AS WINDS BECOME MORE ELY THU EXPECT THE PRESSURE
GRADIENT WILL WEAKEN WITH SPEEDS DROPPING TO 10 KTS OR LESS THROUGH
THE REMAINDER OF THE FORECAST PERIOD AS HIGH PRESSURE OVER THE
ATLANTIC BEGINS TO DOMINATE. SEAS 2-4 FT.
