AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
300 PM EDT SAT JUL 27 2002

CURRENTLY...SCT CONVECTION HAS BEEN ONGOING IN THE GA ZONES DUE TO
LOW LEVEL CONVERGENCE ASSOCD WITH Q-STRNY TROUGH AND VORT LOBE
ACROSS NERN FL. CAPES ON THE ORDER OF 2500-3000 J/KG PER GOES
SOUNDINGS. WITH PWATS AROUND THE 2 INCH MARK WOULD ONLY EXPECT ISOL
PULSE-SEV STORMS AFTN AND EVENING. SLOW MOVING STORMS WILL DUMP VERY
HEAVY RAINFALL AMOUNTS. Q-STRNY SFC RIDGE WAS OVER CENTRAL FL. LIGHT
WINDS ARE PROMOTING E AND W COAST SEA BREEZE PENETRATION INLAND.

TONIGHT...EXPECT MOST CONVECTION TO BE IN THE ERN ZONES THIS
EVENING AS ATMOS HAS NOT BEEN TAPPED YET. THEREFORE WILL PLACE
HIGHER POPS IN THIS AREA.

SUN THROUGH TUE...RIDGE WILL CONT S OF THE FORECAST AREA AND WILL
LIKELY DIP FURTHER S. MODELS ARE PRETTY SIMILAR ALOFT WITH 5H HIGH
PRES OVER CENTRAL GA SLOWLY SHIFTING E TO AS A TROPICAL WAVE SLIPS
UNDER RIDGE THROUGH SRN FL. MODEL PWATS DROP SLIGHTLY BUT TEMPS
ALOFT WILL TEND TO COOL AS WAVE MOVES INTO THE FL PENINSULA. WILL
KEEP POPS MAINLY IN THE SCT RANGE...BUT FAVORING FL CWA DUE TO SEA
BREEZE BOUNDARIES. BY MON AND TUE...SOME DRIER AIR ALOFT SHOULD
SUPPORT A BETTER CHANCE OF STRONG-SEVERE PULSE THUNDERSTORMS.

EXTENDED...AVN SHOWS A FRONTAL BOUNDARY DROPPING INTO THE CAROLINAS
AND NRN GA. THIS SHOULD HELP POOL MOISTURE INTO THE REGION AND
MAINTAIN NEAR CLIMO POPS AND TEMPS.

MARINE...BUOY 41008 SW 6G8 KT WITH SEAS 2 FT. BUOY 41012 HAS SW 6G8
KT SEAS 2.6 FT. BOTH SEAS PRIMARILY ESE SWELLS WITH PERIODS AROUND

LITTLE CHANGE.
