AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
917 AM EDT MON MAY 15 2006

...SEVERE STORMS POSSIBLE THIS AFTERNOON...

.SHORT TERM...MSAS ANALYSIS INDICATES COLD FRONT HAS MADE ITS WAY
INTO SOUTH CENTRAL GEORGIA...JUST ENTERING THE FORECAST AREA. RUC
INDICATES THAT ALONG AND AHEAD OF THIS IS A ZONE OF HIGH THETA-E
VALUES FROM THE SUWANNEE VALLEY THROUGH THE GEORGIA COAST. THIS
HAS PROVIDED THE FOCUS FOR THE SHOWERS CURRENTLY ON RADAR WITH
ISOLATED THUNDERSTORMS PRESENT AS WELL. THE MAIN CHALLENGE FOR
TODAY WILL BE DETERMINING THE RESULTS OF DIMINISHING SYNOPTIC
EFFECTS ALONG WITH INCREASED MESOSCALE INFLUENCES IN AN
INCREASINGLY UNSTABLE ENVIRONMENT. AS MAIN SHORTWAVE TROUGH DIVES
INTO THE WESTERN GULF...DIFFLUENCE ALOFT LOOKS TO BE ON THE WANE
OVER OUR AREA AND THIS IS ALREADY EVIDENCED BY WARMING CLOUD TOPS
ON IR IMAGERY. SO EXPECT THE LINE OF SHOWERS TO REMAIN STEADY
STATE OR PERHAPS SLIGHTLY WEAKEN AS IT PROGRESSES SOUTHWARD.

MAIN IMPACT FROM THIS ACTIVITY WILL BE TO PUT OUT SOME SOUTHWARD
PROPAGATING OUTFLOWS INTO THE FLORIDA PORTION WHICH WILL ACT AS A
FOCUS FOR ADDITIONAL STORM DEVELOPMENT THIS AFTERNOON. MODEL
SOUNDINGS SHOW A VERY IMPRESSIVE UNSTABLE PROFILE FOR AREAS SOUTH
OF I-10 THIS AFTERNOON. MODIFIED GNV SOUNDINGS FOR A HIGH IN THE
LOWER 80S SHOWS CAPES AROUND 3000 WITH VERY GOOD INSTABILITY IN
THE HAIL GROWTH ZONES. MOST OF THE SURFACE INSTABILITY COMES
COURTEOUS OF INCREASED MOISTURE OFF THE GULF THIS AFTERNOON. ALL
IN ALL CURRENT FORECAST HAS A GOOD HANDLE ON THE SITUATION AND
ONLY SOME MINOR CHANGES ARE PLANNED.

&&

.MARINE...CURRENT FORECAST IN GOOD SHAPE AND NO CHANGES PLANNED.

.PREV DISCUSSION... (ISSUED 300 AM EDT MON MAY 15 2006)

..ISOLD SEVERE STORMS POSSIBLE TODAY...

SYNOPSIS...A BROKEN LINE OF CONVECTION PRECEDING A QUASI-STATIONARY
FRONTAL BOUNDARY IS EDGING ITS WAY EASTWARD FROM THE WEST FL
PANHANDLE TOWARD OUR N GA ZONES THIS HOUR. POCKETS OF DIFFERENTIAL
POSITIVE VORTICITY ADVECTION ARE AIDING THESE NOCTURNAL STORMS AS
THEY ROUND THE BASE OF A LARGE UPPER LEVEL VORTEX POSITIONED OVER
IN/OH. WEAK RIDGING TO OUR SE IS YIELDING TO THE DEEPENING UPPER
TROUGH. PLENTY OF MID AND HIGH CLOUDS ARE STREAMING OVER THE JAX CWA
TONIGHT COURTESY OF A DEEP SUB-TROP MOISTURE PLUME FROM OLD MEX
EXTENDING NE TOWARD THE CAROLINAS.

SHORT TERM...TODAY THROUGH WED...
FRONTAL BOUNDARY TO OUR N WILL SAG INTO THE JAX CWA TODAY AS THE
UPPER LEVEL LOW DEEPENS AND SHIFTS SOUTHWARD. PLENTY OF FORCING
IN THE FORM OF MID LEVEL DIFF PVA AND ASCENT COURTESY OF BOTH MID
AND UPPER LEVEL JETS WILL PROVIDE DYNAMICAL SUPPORT ALONG AND AHEAD
OF THE FRONT FOR CONVECTION. INSTABILITY INDICES WILL CONTINUE
TO INCREASE OVER THE AREA THIS MORNING AS THE UPPER TROUGH SHIFTS
FURTHER SOUTH AND TEMPS ALOFT COOL...WHICH WILL STEEPEN MID LEVEL
LAPSE RATES WHILE AT THE SAME TIME INCREASE MID LVL FLOW. THEREFORE
THE MAIN CONVECTIVE CONCERNS FROM STRONG STORMS TODAY WILL BE HAIL
AND GUSTY WINDS...AND HAVE HIGHLIGHTED THESE IN THE FORECAST. DEEP
LAYER WSW STEERING FLOW WILL KEEP THE EAST COAST SEABREEZE PINNED
NEAR THE COAST THIS AFTN...BUT THE SB COULD PROVIDE AN ADDITIONAL
FOCUS FOR STORMS/ISOLD ROTATING STORMS OVER OUR EASTERN FL ZONES AS
THE AFOREMENTIONED FRONT SAGS INTO THE AREA DURING THE LATE
AFTN/EVENING. HAVE CONTINUED WITH A GOOD CHANCE OF PRECIP FOR THE
HEART OF OUR CWA TODAY...LEANING TOWARD THE MAV MOS. COOLER MAX TEMPS
ARE EXPECTED COMPARED TO YSTDY AS CLOUD COVER INCREASES RANGING FROM
UPPER 70S TO OUR N TO LOWER 80S FOR OUR S ZONES.

TONIGHT THE UPPER LOW BEGINS TO LIFT NE TRAILING THE SURFACE FRONT
THROUGH OUR FL ZONES. HAVE CONTINUED WITH SCATTERED PRECIP THROUGH
MIDNIGHT...THEN DECREASE POPS FROM N-S AS DRIER AIR BEGINS TO FILTER
IN FROM THE NW. TUE THE FRONT LINGERS ACROSS CENTRAL FL...AND HAVE
CONTINUED A LOW CHANCE OF PRECIP FOR OUR SOUTHERN ZONES (MARION...
PUTNAM AND FLAGLER).

MODELS INDICATE A WAVE FORMING ALONG THE FRONT LATE TUE AND TRACK THE
FEATURE ENE ACROSS S FL AS MEAN LAYER TROUGHING OVER THE EASTERN
CONUS FINALLY BEGINS TO TRANSLATE EAST STEERING THE SFC WAVE AND
STALLED FRONT OFFSHORE OF THE FL COAST BY LATE WED. HAVE INDICATED A
LOW CHANGE OF SHRA FOR OUR SE FL ZONES LATE TUE/EARLY WED ASSOCIATED
WITH THIS DEPARTING WAVE FEATURE.

TEMPS WILL BE ACTUALLY BELOW CLIMO VALUES IN THE SHORT TERM DUE TO
MEAN TROUGHING OVER THE EASTERN CONUS. HIGHS NEAR 80 AND MINS IN THE
LOW 60S TONIGHT TO MID 50S BY TUE NIGHT CAN BE EXPECTED. PATCHY FOG
WILL BE ALSO POSSIBLE TONIGHT ESPECIALLY WHERE PRECIP FALLS TODAY.

LONG TERM...THU THROUGH SUN...
CONTINUED A DRY FORECAST AS TROUGHING WEAKENS OVER THE EASTERN CONUS
WITH A SPLIT FLOW JET PATTERN DEVELOPING BY THE WEEKEND. EXPECT MORE
ZONAL FLOW BY SUN WITH THE SUB-TROP JET OVERHEAD. AT THE SURFACE WLY
FLOW WILL PREVAIL AS RIDGING REMAINS TO OUR SOUTH WHICH WILL KEEP
DEEP MOISTURE TO OUR NORTH ASSOCIATED WITH WEAK FRONTS. TEMPS WILL
MODERATE THROUGH THE PERIOD FROM LOWER 80S/MID 50S THU TO NEAR 90/LWR
60S BY SUN.
