CONCERNING...TORNADO WATCH 949...
VALID 101908Z - 102015Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 949 CONTINUES.
TORNADO WATCH 949 IS SET TO EXPIRE AT 20Z. WFO LOCAL EXTENSIONS
COULD OCCUR...BUT IT DOES NOT APPEAR THAT A NEW WW WILL BE NEEDED
THROUGH EARLY EVE.
KINEMATIC SET-UP HAS BEEN SLOWLY EVOLVING INTO AN ANAFRONTAL
SITUATION THIS AFTN AS LOW/MID-LVL FLOW BACKS DOWNSTREAM FROM THE TX
UPR LOW. LEADING EDGE OF AN EXPANDING AREA OF CONVECTION HAS
MAINTAINED A BOUNDARY FROM CNTRL GA SWWD INTO THE WRN FL PNHDL WHERE
STRONGER TSTMS HAVE BEEN CONFINED. VERY SLOW SEWD TRANSLATION OF
THIS BAND WILL FOSTER VERY HEAVY RAINFALL AMOUNTS/RATES THROUGH LATE
AFTN...ESPECIALLY AS PRE-FRONTAL STORMS FEED NWD INTO THE BAND.
EMBEDDED SMALL-SCALE LEWPS AND BRIEF SUPERCELL STRUCTURES WILL
REMAIN POSSIBLE GIVEN FAVORABLE DEEP LAYER SHEAR. LOW-LEVEL
SHEAR...WHICH HAS RELAXED SOMEWHAT SINCE THIS MORNING... IS NOT
EXPECTED TO INCREASE UNTIL LATER TONIGHT. CONSEQUENTLY...THE SVR
THREATS /DMGG WIND AND/OR A BRIEF TORNADO/ SHOULD NOT INCREASE FOR
SEVERAL MORE HOURS...LIKELY REMAINING ISOLD. AS SUCH...A NEW
WEATHER WATCH DOES NOT SEEM WARRANTED.

1159 PM CST WED DEC 10 2008
VALID 111200Z - 121200Z
...THERE IS A SLGT RISK OF SVR TSTMS TIDEWATER TO WRN/NRN FL...
...SYNOPSIS...
LARGE-SCALE UPPER TROUGH FCST TO REMAIN OVER E-CENTRAL NORTH AMERICA
THROUGH PERIOD...FROM HUDSON BAY REGION SSWWD ACROSS WRN/CENTRAL
GULF. SHORTWAVE MID-UPPER LEVEL CYCLONE -- INITIALLY ANALYZED OVER
SE TX VICINITY GLS BAY -- IS ACCOMPANIED BY AT LEAST 100 M PER 12
HOUR 500 MB HEIGHT FALLS AS ANALYZED OVER LOWER TX COAST...WITH
GREATER FALLS LIKELY OVER WRN GULF RAOB DATA VOID. THIS LOW IS
EXPECTED TO PIVOT EWD THROUGH BEGINNING OF THIS DAY-1 PERIOD...THEN
LIFT NEWD ACROSS SRN AL AND OUT OF MEAN TROUGH POSITION. AS THIS
OCCURS...EXPECT PERTURBATION TO DEAMPLIFY AND BECOME OPEN-WAVE IN
CHARACTER AFTER ABOUT 12/00Z. RESULTING TROUGH THEN WILL WEAKEN
CONSIDERABLY AND ACCELERATE ACROSS CAROLINAS DURING 12/06Z-12/12Z
TIME FRAME.
ASSOCIATED SFC CYCLONE -- NOW ANALYZED OVER GULF SW PNS -- IS
EXPECTED TO MOVE INLAND BEFORE 11/12Z...THEN NEWD ALONG INITIALLY
QUASISTATIONARY FRONTAL ZONE ACROSS ERN AL AND NWRN GA EARLY IN
PERIOD...OCCLUDING INVOF NRN GA. OCCLUSION/TRIPLE-POINT LOW THEN
SHOULD LIFT NEWD FROM UPSTATE SC TO SERN VA...WHILE TRAILING COLD
FRONT SWEEPS EWD FROM ERN GULF ACROSS FL PENINSULA. NRN SEGMENT OF
FRONT SHOULD MOVE OFFSHORE NC BY AROUND 12/06Z.
...EARLY PERIOD...FL AND CENTRAL/SRN GA...
EARLY IN PERIOD...SCATTERED-NUMEROUS TSTMS ARE POSSIBLE AHEAD OF
COLD FRONT OVER SC/GA...THEN ALONG OR JUST AHEAD OF FRONT OVER NERN
GULF...MOVING ASHORE FL W COAST. AS SFC LOW MOVES INLAND EARLY IN
PERIOD...ASSOCIATED ISALLOBARIC FORCING AND NEAR-SFC BACKING WILL
CONTRIBUTE TO FAVORABLE VERTICAL SHEAR PROFILES ACROSS PORTIONS FL
PANHANDLE....NRN/WRN FL PENINSULA AND SRN GA.
INITIAL DEVELOPMENT OF GULF LINE HAS OCCURRED ALREADY -- AS EVIDENT
IN IR IMAGERY. FLOW ALONG FL W COAST THEN SHOULD VEER SLIGHTLY WITH
TIME PRIOR TO FROPA...WHICH WILL REDUCE LOW LEVEL SHEAR SLIGHTLY BUT
WHICH ALSO SHOULD INCREASE MOISTURE AND BUOYANCY BY MEANS OF ONSHORE
ADVECTION OF GULF MARINE LAYER. THIS SHOULD ALLOW CONVECTION TO
SURVIVE INLAND....PERHAPS LONG ENOUGH TO BE ENHANCED BY
PRECURSORY/GRADUAL DIURNAL HEATING DURING MID-LATE MORNING HOURS.
SVR POTENTIAL BECOMES WEAKER AND MORE CONDITIONAL WITH SWD EXTENT
OVER FL PENINSULA BECAUSE OF CONTINUING VEERING...AND RESULTING
WEAKENING TRENDS OF SHEAR/CONVERGENCE WITH TIME. THEREFORE...SVR
PROBABILITIES ARE KEPT AT MRGL LEVELS ATTM FOR SRN PENINSULA. MRGL
BUOYANCY AND PERHAPS MESSY...CLUSTERED OR LINEAR CONVECTIVE MODES
WILL TEMPER BUT NOT REMOVE SVR THREAT...WHICH CONSISTS MAINLY OF
DAMAGING GUSTS AND A FEW TORNADOES POSSIBLE WITH BOW/LEWP FORMATIONS
AND PERHAPS EMBEDDED SUPERCELLS.
...TIDEWATER TO SRN ATLANTIC COAST REGION...
STRENGTHENING SHEAR AND AT LEAST MRGLLY FAVORABLE BUOYANCY WILL
SUPPORT SVR THREAT FROM ERN GA NEWD TO TIDEWATER AREA DURING
AFTERNOON...PRIOR TO PASSAGE OF FRONT OR PREFRONTAL
CONVECTIVE/CONVERGENCE BELT. ATTM IT APPEARS THAT
ONGOING/PRECURSORY PRECIP...CLOUD COVER...RESULTING SUPPRESSION OF
DIABATIC SFC HEATING...AND LACK OF STEEPER MIDLEVEL LAPSE RATES WILL
RESTRICT DESTABILIZATION ACROSS THIS REGION...KEEPING MLCAPES BELOW
ABOUT 750 J/KG MOST AREAS. HOWEVER...EVIDENCE OF GREATER
DESTABILIZATION MAY COMPEL UPGRADE IN SUCCEEDING OUTLOOKS...GIVEN
STRENGTH OF KINEMATIC FIELDS EXPECTED.
MOST SUITABLE JUXTAPOSITION OF SUSTAINED/FAVORABLE SFC
THETAE...DEEP-LAYER SHEAR AND FOCI FOR RELATIVELY DENSE CONVECTIVE
COVERAGE SHOULD BE ACROSS MUCH OF CENTRAL/SRN CAROLINAS DURING
AFTERNOON...HENCE MAXIMIZED WIND PROBABILITIES IN THAT REGION.
50-60 KT LLJ IS FCST JUST ABOVE SFC...AND STG MOMENTUM ALOFT MAY BE
BROUGHT TO SFC IN DOWNDRAFTS TO YIELD WIND DAMAGE. FCST SOUNDINGS
INDICATE 50-60 KT EFFECTIVE SHEAR MAGNITUDES ARE POSSIBLE...WITH 0-1
KM SRH 200-300 J/KG...SUPPORTING BOTH BOWING AND SUPERCELLULAR
STRUCTURES CONCURRENT WITH SFC-BASED EFFECTIVE LIFTED PARCELS.
THEREFORE THREAT FOR A FEW TORNADOES ALSO EXISTS.

AREAS AFFECTED...CENTRAL/NRN FL AND SRN/SERN GA
CONCERNING...TORNADO WATCH 950...
VALID 111324Z - 111430Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 950 CONTINUES.
THREAT FOR DAMAGING WINDS AND ISOLATED TORNADOES REMAINS ALONG EWD
MOVING SQUALL LINE THROUGH SRN GA/NRN-CENTRAL FL THIS MORNING.
CURRENT MOVEMENT OF THIS LINE /ENE AT 35-40 KT/ SUGGESTS THE NRN
EXTENT WILL LIKELY REACH SERN GA/NERN FL BY 15Z...WHILE THE LINE
FURTHER S MOVES EWD ACROSS CENTRAL PENINSULA THROUGH 15-16Z.
AT 13Z...REGIONAL RADARS SHOWED A SQUALL LINE EXTENDING FROM SWRN
GA/NWRN FL...TO ALONG THE W CENTRAL COAST OF FL...AND THEN SSWWD TO
135 W EYW. LIGHTNING DATA INDICATED A DECREASING TREND IN STRIKES
AS THIS SQUALL LINE ENCOUNTERED THE COOLER SHELF WATERS ALONG THE FL
W COAST. A MOIST/MARGINALLY UNSTABLE AIR MASS WAS IN PLACE AHEAD OF
THIS SQUALL LINE. DESPITE THE WEAK INSTABILITY...DEEP LAYER ASCENT
AHEAD OF THE NWRN GULF COAST CLOSED LOW SHOULD MAINTAIN A FORCED
LINE OF CONVECTION SPREADING EWD ACROSS FL/SRN GA THROUGH THIS
MORNING. AREA WSR-88D VWP AND 12Z SOUNDINGS SHOWED STRONG DEEP
LAYER WIND FIELDS RESULTING IN EFFECTIVE BULK SHEAR AROUND 50 KT.
THIS SHOULD MAINTAIN ORGANIZATION OF THE LINE WITH POTENTIAL FOR
STRONG WINDS REACHING THE SURFACE...WHILE SFC-1 KM SHEAR OF 30-40 KT
SUPPORTS A TORNADO THREAT WITH ANY EMBEDDED SUPERCELLS IN THE LINE.
