AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 215 PM EDT MON JUL 30 2007 ...ISOLATED SEVERE STORMS AND HEAVY RAINFALL POSSIBLE THIS AFTERNOON... .SHORT TERM... THIS AFTERNOON AND EVENING...WEAKENING EAST COAST TROUGH LINGERS WHILE SURFACE FRONT IS STRETCHING ROUGHLY ALONG THE EAST COAST...THEN BACK THROUGH CENTRAL GA/AL/MS. A VERY MOIST AND UNSTABLE AIRMASS IS ALREADY INFLUENCING CONVECTION...WITH STORMS DEVELOPING AHEAD OF THE WEAK FRONTAL BOUNDARY. THIS MORNINGS SOUNDING SHOWS A PWAT OF 2.14 INCHES AND ROUGHLY 3400 J/KG OF CAPE USING A T/TD OF 92/72. THIS CAPE ESTIMATE SEEMS REASONABLE GIVEN CURRENT T/TD OBSERVATIONS...ALTHOUGH POCKETS OF HIGHER MOISTURE AND INSTABILITY EXIST WITH A FEW METARS READING DEW POINTS IN THE MID TO UPPER 70S. SEVERE STORMS ARE NOT OUT OF THE QUESTION THIS AFTERNOON AND CONVECTIVE COVERAGE WILL BECOME MORE WIDESPREAD THIS EVENING GIVEN ABUNDANT MOISTURE AND INSTABILITY. EXPECT FURTHER DEVELOPMENT ALONG ANY OUTFLOW BOUNDARIES AND SEA BREEZES. THE MAIN THREAT WILL BE DAMAGING WINDS GIVEN WET MICROBURST PROFILE...ALTHOUGH TEMPERATURES ALOFT ARE STILL RELATIVELY COOL AND COULD SUPPORT HAIL IN THE STRONGER STORMS. STORM MOTION IS STILL WEAK AND WITH AMPLE MOISTURE EXPECT HEAVY DOWNPOURS AND LOCALIZED FLOODING. TUESDAY AND WEDNESDAY...FRONTAL BOUNDARY WILL GRADUALLY SAG SOUTHWARD.

TEMPERATURES WILL BE NEAR CLIMO FOR HIGHS...AND ABOVE NORMAL FOR LOWS DUE TO MOISTURE AND CLOUD COVER. .LONG TERM...CONSIDERABLE AMOUNT OF UNCERTAINTY IN THE EXTENDED PERIOD. GIVEN THE GFS SCENARIO THE BERMUDA HIGH REFORMS TO THE EAST OF THE FLORIDA PENINSULA...WHILE LOW PRESSURE JUST TO THE WEST AND ABUNDANT MOISTURE REMAIN OVER THE SOUTHEAST. THIS ALSO KEEPS A FRONTAL BOUNDARY STALLED ALONG THE GULF AND THROUGH OUR CWA. GIVEN THE DGEX SCENARIO THIS HIGH PRESSURE REFORMS RIGHT OVER THE SOUTHEAST BY FRIDAY KEEPING US IN A DRY PATTERN. WITH SO MUCH UNCERTAINTY...HAVE OPTED TO KEEP POPS CLOSE TO CLIMO. && .AVIATION...CONVECTION STILL YET TO FIRE NEAR TERMINALS BUT A FEW STORMS HAVE FORMED 20-25 MILES WEST OF SSI. WITHIN NEXT HOUR EXPECT VCTS NEAR GNV AND SSI WITH TEMPO FOR STORMS THROUGH ABOUT 00Z FOR JAX SSI AND CRG. THINK STORMS WILL BE SHIFTING OFF TO THE E OF GNV BY 22Z/23Z ALTHOUGH STILL A RISK OF OTHER STORMS MOVING IN FROM THE NW FROM SUWANNEE VALLEY. OTHERWISE...HAVE PRECIP ENDING BY 00Z WITH VCSH THEREAFTER TIL 03Z. ANY FOG SHOULD BE AT A MINIMUM TONIGHT DUE TO UNFAVORABLE TROUGHING ALOFT BUT POSSIBLE MVFR VIS NEAR GNV LATE TONIGHT/EARLY TUESDAY PER CONSENSUS OF GUIDANCE. && .MARINE...SOUTH TO SOUTHWEST WINDS PREVAIL TONIGHT DUE TO FRONT BEING N OF THE AREA. MODEL GUIDANCE IN GOOD AGREEMENT SHOWING WINDS VEERING ON TUESDAY AS FRONT PRESSES SWD INTO SRN GA. WEAK COLD FRONT EXPECTED TO PUSH INTO NE FL BY WEDNESDAY MORNING OR AFTERNOON WITH NE TO E FLOW DEVELOPING OVER MAJORITY OF MARINE ZONES AS HIGH PRESSURE RIDGE BUILDS IN FROM THE N. FRONT WILL TEND BECOME MORE DIFFUSE BY LATE WED NIGHT INTO THU AS IT STALLS OVER OUR AREA AND DRIFTS WWD. FLOW EXPECTED TO SHIFT TO BACK TO A S TO SE FLOW BY LATE THIS WEEK AS LOW TO MID LEVEL RIDGE BUILDS BACK OVER FL. NO HEADLINES REQUIRED AT THIS TIME.
