AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE JACKSONVILLE FL
234 PM EDT SAT JUN 9 2007
.SHORT TERM...MSAS ANALYSIS SHOWS THAT TROUGH OF LOW PRESSURE NOW
EXTENDS FROM THE EXTREME COASTAL SECTIONS OF NORTH AND SOUTH
CAROLINA THROUGH SOUTHEAST GEORGIA AND NORTHEAST FLORIDA. THIS IS
ROUGHLY THE SAME POSITION AS DEEP LAYER MOISTURE AXIS DEPICTED BY
THE WATER VAPOR IMAGERY WHICH IS SLOWLY SHIFTING SOUTH THROUGH THE
EARLY AFTERNOON HOURS. ACTIVITY HAS BEEN A LITTLE SLOWER IN
GETTING GOING TODAY WITH CU JUST NOW BEGINNING TO DEVELOP ALONG
THE FLORIDA GEORGIA BORDER. AREA OBSERVATIONS INDICATE A LITTLE
BETTER MIXING OF DRY AIR TO THE SURFACE WITH DEWPOINTS RESIDING
MORE IN THE UPPER 60S AS OPPOSED TO THE LOWER 70S WE HAVE SEEN THE
PAST FEW AFTERNOONS. DESPITE THE LATER START...FEEL ACTIVITY WILL
STILL GET GOING ACROSS INTERIOR PORTIONS AND RIGHT NOW FAVORING
THE FLORIDA PORTION FOR THE GREATEST COVERAGE. STILL COULD BE SOME
STORMS EARLY THIS AFTERNOON ACROSS INTERIOR SE GA WITH THETA-E
RIDGE AXIS IN PLACE BUT THIS FEATURE WILL SHIFT SOUTHWARD WITH THE
ADVANCEMENT OF THE SURFACE TROUGH. AS MENTIONED N PREVIOUS AFDS
AND SPC DISCUSSION...DRIER AIR ALOFT WILL AID IN PULSE STRONG TO
SEVERE WITH MICROBURSTS AND LARGE HAIL POSSIBLE.
WITH THE PASSAGE OF THE TROUGH...MUCH DRIER AIR WILL INFILTRATE
THE NORTHERN ZONES WITH MODELS IN AGREEMENT WRT PWATS FALLING
BELOW AN INCH OVER A GOOD PORTION OF THE GEORGIA ZONES AND
POSSIBLE INTO THE SUWANNEE VALLEY OF FLORIDA. GFS IS MUCH MORE
AGGRESSIVE WITH THIS DRYING AND INDICATES PWATS AS LOW AS HALF AND
INCH BY SUNDAY AFTERNOON. REGARDLESS...POPS WILL BE ON THE
DECREASE AND POSSIBLY NIL OVER A GOOD PORTION OF THE AREA IF MID
50S DEWPOINTS ARE ABLE TO MIX DOWN AS MAV INDICATES. CURRENT POP
DISTRIBUTION LOOKS VERY GOOD WITH LOW END SCATTERED FOR EXTREME
SOUTHEAST ZONES AND A NARROW RIBBON OF SLIGHT CHANCE UP THE
EASTERN SEABOARD AS A RESULT OF SEABREEZE PENETRATION AND
RESULTANT HIGHER DEWPOINTS.
FOR MONDAY...TROUGH POSITION AND UPPER LEVEL FLOW INDICATES WEST
COAST SEA BREEZE WILL MAKE GOOD INLAND PROGRESSION BUT WILL BE
FAIRLY INACTIVE DUE TO THE DEEP LAYER DRYING OVER INTERIOR
SECTIONS. SLIGHTLY HIGHER PWATS WILL BE PRESENT ALONG THE EAST
COAST BUT STILL BELOW CLIMO AND WILL ONLY NEED LOW END SCATTERED
POPS AT BEST.
TUESDAY LOOKS TO BE A TRANSITION DAY AS UPPER TROUGH PROGRESSES
SOUTHWARD DOWN THE EASTERN SEABOARD WITH A SERIES OF UPPER LEVEL
DISTURBANCES ROTATING THROUGH THE BASE. MOISTURE VALUES WILL
INCREASE WITH A RETURN TO SCATTERED CONVECTION AREA WIDE BUT STILL
GENERALLY IN THE 30% TO 40% RANGE. THESE POPS MAY NEED TO BE
ADJUSTED UPWARD AS THE EVENT DRAWS CLOSER AS WILL THE WORDING IN
THE HWO. UPPER TROUGH WILL PROVIDE COOLING CONDITIONS ALOFT WITH
500 TEMPS NEAR -11C LATE TUESDAY.
.LONG TERM...ONLY CONCERN FOR THE LONG TERM WILL BE THE
POSSIBILITY OF ANY WEAK LOW DEVELOPMENT WITH THE ARRIVAL OF UPPER
TROUGH. CURRENT GRIDS LOOKS IN GOOD SHAPE AND NO CHANGES PLANNED.
&&
.AVIATION...FEW-SCT CU FORMING WITH BEST CHANCES PROGGED FOR
GAINESVILLE FOR TEMPO 2-3SM TSRA. OTHERWISE...VFR CONDS PREVAIL.
PATCHES OF FOG SRN TAF SITES POSSIBLE LATE TONIGHT AND FOR NOW HAVE
LEFT IT PREVAILING VFR VIS.
&&
.MARINE...SWLY WINDS INCREASE TO ABOUT 15 KT OFFSHORE TONIGHT AND SO
AT THIS TIME SCEC IS NOT PLANNED. OTHERWISE...GENERALLY GOOD BOATING
CONDS FOR NEXT FEW DAYS. SEA BREEZES AND SLY FLOW WILL DOMINATE THE
WATERS INTO EARLY NEXT WEEK. SEAS AOB 3 FT.
&&
.FIRE WEATHER...DRIER AIR ADVECTING INTO THE AREA HAS PROMPTED THE
ISSUANCE OF RED FLAG WARNING FOR INLAND NE FL FOR SUNDAY...
SUWANNEE VALLEY AREA WITH FIRE WEATHER WATCH FURTHER E INTO EXTREME
NE FL. MARGINALLY LOW RH VALUES APPEAR ON MONDAY BUT WILL WAIT FOR
ANOTHER MODEL CYCLE BEFORE ISSUING ADDITIONAL WATCHES.
