AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSONVILLE FL
620 AM EDT SUN MAY 11 2008

.UPDATE...TOR WATCH ISSUED UNTIL 17Z FOR THE NRN HALF OF OUR FCST
AREA GIVEN EWD MOTION...AND SWD DVLPMENT...OF MCS OVER WCTRL GA.
SOME UNCERTAINTY AS TO HOW FAR SOUTH NEW CONVECTION WILL DEVELOP AS
LLJ IMPINGES ON SOUTHERN PART OF MCS...GREATEST T-STORM COVERAGE AND
SEVERE THREAT THROUGH THE MORNING WILL STILL BE ACRS SCTRL AND SE
GA...WITH MORE ISOLATED ACTIVITY FURTHER SOUTH LATER IN THE MORNING.
ALSO UNCERTAIN AS TO HOW MUCH...IF ANY...NEW CONVECTIVE DEVELOPMENT
WILL OCCUR LATER THIS AFTN IN WAKE OF MCS AS MODELS SUGGEST WEAK
SUBSIDENCE...AT LEAST ACRS NE AND NCTRL FL. BEST CHANCE OF ANY AFTN
DEVELOPMENT APPEARS TO BE ACRS GA. IN FORECAST UPDATE...MAINTAINED
HIGHEST POPS ACRS OUR GA COUNTIES...WITH LOWER POPS ACRS NE FL.

&&

----------------------------------

.SHORT TERM...WARM AND WINDY CONDITIONS EXPECTED TODAY AS SFC LOW
DEEPENS TO OUR NORTH...YIELDING GUSTY SW TO WSW WINDS AT 20 MPH
WITH GUSTS IN THE 30-35 MPH RANGE. WILL HOIST LAKE WIND ADVISORY FOR
FORECAST AREA THROUGH THE AFTN AND EARLY EVNG HOURS. WILL START OUT
WITH LOW CLOUDINESS FROM GULF OF MEX THIS MORNING...BUT WITH WINDS
GAINING MORE WRLY COMPONENT AND SUBSIDENCE DEVELOPING OVER NRN/CTRL
FL...EXPECT SKIES TO BECOME PARTLY CLOUDY...ALLOWING TEMPS TO RISE
INTO M/U 80S SE GA AND UPR 80S/LWR 90S NE FL.

STORM SYSTEM INTENSIFIES AS IT MOVES TOWARD EASTERN U.S. TODAY. THE
COMBINATION OF WARM UNSTABLE AIR AND STRONG WIND SHEAR SUGGEST THE
POTENTIAL FOR SEVERE T-STORMS ACROSS MUCH OF THE SOUTHEAST. UPR JET
AXIS IS FORECAST TO MOVE ACRS CTRL GA...WITH LIFT ALONG AND N OF
JET...SUBSIDENCE S (AS GIVEN BY MODEL FCST SNDGS FOR THIS AFTN).
ANTICIPATE T-STORMS TO BE MOST WIDESPREAD, AND MOST INTENSE...N OF
OUR FORECAST AREA...FROM CTRL GA ACRS SC INTO ERN NC...WITH
DECREASING COVERAGE AS YOU GO SOUTHWARD. ACRS NE AND NCTRL
FL...ANTICIPATE ONLY ISOLATED T-STORMS AT BEST GIVEN SUBSIDENCE.
BEST CHANCE OF SEVERE T-STORMS WILL BE OUR NRN COUNTIES IN SE
GA..WITH PRIMARY THREATS BEING LARGE HAIL AND STRONG WIND GUSTS.
ANY ISOLATED T-STORM THAT DEVELOPS IN NE FL COULD BECOME STRONG OR
BRIEFLY SEVERE GIVEN THE COMBINATION OF INSTABILITY AND DEEP-LAYER
SHEAR.

ACTIVITY COMES TO AN END THIS EVNG...WITH BREEZY CONDITIONS
CONTINUING. COOLER CONDITIONS ARE EXPECTED MON/TUES. BREEZY
CONDITIONS CONTINUE MON...WITH LIGHTER WINDS TUES AS HIGH PRESSURE
BUILDS OVER THE EASTERN STATES.

.LONG TERM...WARMING TREND EXPECTED DURING LATTER HALF OF WORKWEEK.
SOME UNCERTAINTY ON RAIN CHANCES LATER IN THE WEEK WITH CHANGES IN
THE LATEST MODEL SOLUTIONS. BEST CHANCE STILL APPEARS TO BE FRI/SAT.

&&

.AVIATION...WITHIN THE PAST FEW HOURS...STRATUS DECK WHICH HAD
PREVIOUSLY ONLY AFFECTED THE GNV TERMINAL...HAS NOW SHIFTED EAST AND
IFR TO MVFR CONDITIONS ARE AFFECTING MOST OF THE FLORIDA PORTION.
EXPECT THIS TREND TO CONTINUE THROUGH 10Z AND THEN INCREASED MIXING
MAY ALLOW THIS DECK TO INCREASE TO VFR ONCE AGAIN TOWARD DAYBREAK.
FOCUS WILL THEN SHIFT TO THE APPROACHING SQUALL LINE WHICH BY THE
TIME IT REACHES OUR AREA WILL BE MOISTURE DEPRIVED. ENOUGH OF A LINE
LEFT TO WARRANT TEMPO FOR SSI AND HAVE HESITANTLY INCLUDED AND SHORT
TERM TEMPO FOR CRG AND JAX AS WELL. WILL KEEP VCTS FOR GNV TERMINAL
WITH ONLY SOME MVFR CONDITIONS TO AFFECT THAT AREA FROM 18Z-00Z.

&&

.MARINE...WILL BE MOVING UP THE TIME SLIGHTLY FOR THE ONSET OF
SMALL CRAFT ADVISORY CONDITIONS ACROSS THE COASTAL WATERS TO
COINCIDE WITH LAKE WIND ADVISORY TIME OF 15Z. WILL ACTUALLY SEE A
PERIOD AFT 06Z MON OF 25 KNOT WINDS WITH GUSTS TO GALE FORCE
LIKELY. WILL KEEP JUST SCA FOR NOW...BUT THESE TRENDS WILL NEED TO
BE MONITORED CLOSELY FOR SUBSEQUENT FORECASTS FOR POSSIBLE GALE
WARNINGS FOR THE GA WATERS. ALTHOUGH SUSTAINED WINDS ARE FORECAST
TO COME DOWN SLIGHTLY FOR MON AFTERNOON...BOSTON TECHNIQUE SUGGEST
VERY STRONG WIND GUSTS POSSIBLE IN BETTER DEVELOPING MIXING PROFILE.

&&

.FIRE WEATHER...DESPITE THE PRESENCE OF SEVERE WEATHER TODAY...WE
WILL ACTUALLY SEE PORTIONS OF THE CWA THAT WILL COME CLOSE TO
VERIFYING RED FLAG CONDITIONS. EXPECT THE SOUTHERN TIER OF THE
AREA WITH A VERY GOOD MIXING PROFILE AND DRY AIR ALOFT WILL SEE RH
VALUES TAIL OFF INTO THE UPPER 30S BY THIS AFTERNOON. ALONG WITH
STRONG WIND GUSTS...THIS AREA WILL NEED TO BE MONITORED FOR
POSSIBLE UPGRADE TO WARNING CONDITIONS SHOULD CLOUD COVER AND
FRONTAL APPROACH BE DELAYED. NO DOUBTS FOR THE FLORIDA PORTION ON
MONDAY AS LATEST GUIDANCE INDICATES LOWER TO MID 20S RH VALUES
AREA WIDE. MEETING THE WIND CRITERIA WILL BE THE BIG QUESTION FOR
THE GA PORTION AND HAVE CHOSEN TO JUST GO WITH A WATCH FOR THAT
PORTION FOR NOW.
