Damaging Wind in Florida, July 16, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
150 PM EDT FRI JUL 16 2004

.SHORT TERM...DEEP UPPER LEVEL TROF AXIS HAS NOW PUSHED A BIT SE OF
THE CWA (COUNTY WARNING AREA). SIGNIFICANT DRYING HAS OCCURRED PER
12Z KJAX SOUNDING AND H2O VAPOR LOOP. HOWEVER...MORE MOISTURE AND
DISTURBANCES MOVING SE FROM UPSTREAM. AT THE SFC...CU FIELD SLOW TO
DEVELOP...WITH MOST CU OVER S TIER AND NW ZONES. ISOLD TSTM
DEVELOPMENT HAS BEEN CONFINED TO MARION COUNTY AND POINTS S WITH
MUCH LESS COVERAGE THAN THU AND WEAKER THUS FAR.

THIS EVENING...EXPECT GREATEST TSTM COVERAGE GENERALLY ALONG AND S OF
A KSGJ TO KGNV LINE. IN ADDITION...A WK SHORT WAVE IS PROGGED TO
MOVE INTO SE GA BY SUNSET...WITH A POSSIBLY TEMPORARY INCREASE IN
COVERAGE OVER THAT AREA AS WELL.

SAT...MODELS PUSH A RATHER POTENT 500 MB VORT MAX ACROSS GA LATE IN
THE DAY. AS A RESULT...SHOULD SEE A WHOLESALE INCREASE IN POPS VS
TODAY. DIFFERENCES IN MODELS REVOLVE AROUND RESULTING LOW-LEVEL LOW
PRESSURE DEVELOPMENT IN RESPONSE TO THIS FEATURE. GFS STILL INSISTS
THAT A 1006 MB LOW WILL DEVELOP ACROSS N OR CENTRAL GA...WITH ETA
SHOWING WEAKER LOW DEVELOPMENT FARTHER N. GFS APPEARS TO HAVE A
SOME CONVECTIVE FEEDBACK ISSUES...SO WOULD LEAN MORE TOWARD ETA
FEATURES. THIS WILL RESULT IN LESS 850 MB WINDS AND LESS SEVERITY
OF STORMS. HOWEVER...ACTIVITY WILL BE QUITE STRONG OVER N GA ZONES
AND SPC HAS THIS AREA IN A SLIGHT RISK.

SUN...MORE SHORTWAVE ENERGY AVAILABLE ROUNDING BASE OF UPPER TROF...
BUT TIMING BECOMES MORE DIFFICULT. WILL CONTINUE HIGH CHANCE POPS
FOR ENTIRE AREA.

.LONG TERM...GFS STILL DEPICTING MID-LEVEL DRYING (ESP OVER N 2/3 OF
THE AREA) EARLY NEXT WEEK. ALTHO UPPER TROF DAMPENS BY MID TO LATE
WEEK...MOISTURE RETURNS ENUF FOR NEAR CLIMO POPS DURING THIS
PERIOD. AS TROF WEAKENS...ABOVE CLIMO TEMPS BY MID TO LATE WEEK.

&&

.MARINE...GRADIENT NOT QUITE AS STRONG OVER THE WATERS TONIGHT SO DO
NOT EXPECT AS STRONG OF A NOCTURNAL SURGE. WENT CLOSE TO ETA FOR
WIND GRIDS THROUGH THE NEXT SEVERAL DAYS AS GFS APPEARS WAY TO STRONG
DUE TO FEEDBACK ISSUES. HOWEVER...MODELS DO AGREE ON OFFSHORE AREAS
APPROACHING SCA CONDITIONS BY SATURDAY NIGHT INTO SUNDAY.
