AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
107 PM EST SAT FEB 28 2009
.SYNOPSIS...
A COMPLEX STORM SYSTEM WILL IMPACT THE REGION THROUGH MON. HIGH
PRESSURE WILL BUILD IN TUE THROUGH FRI.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
ISSUED TORNADO WATCH 42 FOR PORTIONS OF SE GA...VALID UNTIL 8 PM...
TO ACCOUNT FOR THUNDERSTORM COMPLEX ADVANCING ACROSS CENTRAL GA
AND APPROACHING WESTERN COUNTIES OF THE FORECAST AREA. AS THE
AFTERNOON PROGRESSES...WILL ASSESS NEED FOR EXPANSION OF THIS WATCH
FARTHER EAST BASED ON PROGRESS/INTENSITY OF ONGOING CONVECTION.
EARLY SATURDAY AFTERNOON...A WARM FRONT WAS LOCATED OVER FAR NORTHERN
COUNTIES OF THE FORECAST AREA...EXTENDING EAST FROM LOW PRESSURE
APPROACHING THE AL/GA BORDER. WIDESPREAD RAIN/ISOLATED TO
SCATTERED THUNDERSTORMS WERE NOTED ALONG/NORTH OF THE WARM FRONT
WITHIN ISENTROPIC ASCENT/ELEVATED INSTABILITY REGIME...AND
OCCASIONAL SHOWERS WERE BRUSHING FAR INLAND/NORTHERN COUNTIES.
WITHIN THE WARM SECTOR OVER MUCH OF THE FORECAST AREA...LOW/MID
LEVEL WIND FIELDS WERE INTENSIFYING...AND RUC HODOGRAPHS/SPC
MESOSCALE ANALYSIS INDICATED INCREASING LOW LEVEL
HELICITY...EXCEEDING 300 M2/S2. HOWEVER...INSTABILITY REMAINED
WEAK...AS DEWPOINTS REMAINED IN THE 50S...WITH SB LIFTED INDICES
REMAINING ABOVE ZERO. HOWEVER...UPSTREAM CLOSER TO THE SURFACE
LOW...DEWPOINTS HAD SURGED INTO THE 60S...AND THIS INCREASINGLY
UNSTABLE AIRMASS WAS SUPPORTING VIGOROUS CONVECTION WHICH HAS
PROMPTED WARNINGS SATURDAY MORNING.
AS THE SURFACE LOW TRANSLATES EAST...TO A POSITION BETWEEN AGS AND
CAE BY AROUND 0Z...THE SURFACE WARM FRONT WILL LIFT NORTH...AND
THE UPSTREAM UNSTABLE REGIME WILL SHIFT EAST AS WELL...INTO S/W
COUNTIES OF THE FORECAST AREA. THIS SHOULD ALLOW UPSTREAM
CONVECTION TO ADVANCE INTO S/W COUNTIES OF THE FORECAST
AREA...PROVIDING AN INITIAL DAMAGING WIND/LARGE HAIL/ISOLATED TORNADO
THREAT ACROSS THE SOUTHERN 1/2 OF THE FORECAST AREA THIS AFTERNOON
AND THIS EVENING. PUBLIC FORECASTS AND THE HAZARDOUS WEATHER
OUTLOOK WILL CONTINUE TO HIGHLIGHT THE SEVERE THREAT.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SUNDAY/...
THE POTENTIAL FOR SEVERE THUNDERSTORMS WILL CONTINUE INTO TONIGHT...
PERHAPS THIS EVENING WITH ONGOING CONVECTION THEN AGAIN
OVERNIGHT AS THE STRENGTHENING SURFACE LOW TRACKS DIRECTLY THROUGH THE
FORECAST AREA AND DEEP LAYER FORCING/ASCENT INCREASES AHEAD OF AN
AMPLIFYING/UPSTREAM UPPER LOW. OVERNIGHT...IMMENSE 0-3 KM
HELICITY VALUES OF 200-300 M2/S2 WILL TRACK ACROSS SOUTHERN SC
AHEAD OF THE SURFACE LOW BETWEEN 05Z AND 10Z. JUST ABOVE THE
SURFACE...A 50-60 KT 850 MB SSW JET WILL BE POKING INTO THE WARM
SECTOR. A TIGHT BAROCLINIC ZONE ACROSS SOUTHERN SC WILL ENABLE SFC
DEWPOINTS TO POTENTIALLY REACH 60F ACROSS FAR EASTERN ZONES AFTER
MIDNIGHT. THE BUFKIT SOUNDING FOR CHS OFF THE GFS SHOWS CAPES
INCREASING ABOVE 1000 J/KG BETWEEN 06Z AND 12Z WITH MINIMAL
CINH...AND TOTAL TOTALS OF 54. IT IS STILL IMPOSSIBLE TO PIN DOWN
THE EXACT PROGNOSIS BUT WE MAY SEE SOME CLUSTERS OF POTENTIALLY
SEVERE THUNDERSTORMS MOVING THROUGH SOUTHERN SC AFTER MIDNIGHT
TONIGHT WHILE SOUTHEAST GA COULD BE MORE OF A LINEAR SQUALL LINE
ALONG THE TRAILING COLD FRONT. WILL MAINTAIN CATEGORICAL POPS
OVERNIGHT WITH POTENTIALLY SEVERE WORDING THROUGHOUT.
COLDER AIR WILL BEGIN TO FILTER IN FROM THE W LATE TONIGHT.
BELIEVE IT OR NOT...INLAND AREAS EXPECTED TO BOTTOM OUT IN THE
LOWER 40S WITH MID TO UPPER 40S EXPECTED ELSEWHERE.
&&
.LONG TERM /SUNDAY THROUGH SATURDAY/...
THE INTENSE UPPER LEVEL SYSTEM OVER S ALABAMA OR THE FLORIDA
PANHANDLE AT 12Z SUNDAY WILL SHIFT NE TO THE MIDDLE OR LOWER
SAVANNAH RIVER REGION BY 00Z MON. DEVELOPING DYNAMICS ON SUNDAY
ARE EXTREMELY IMPRESSIVE AND WE EXPECTED WIDESPREAD RAIN AND
MORNING CONVECTION ALONG THE GEORGIA COAST N TO SE SOUTH CAROLINA
TO SHIFT NE INTO THE PEE DEE WITH A POSSIBLE BRIEF RESPITE FROM
MORE SIGNIFICANT RNFL AS A DRY SLOT NOSES UP INTO SE GEORGIA AND
DURING THE AFTERNOON. WE ADDED SMALL HAIL TO SOUTH CAROLINA ZONES
DURING THE MORNING AS THE INITIAL CONVECTIVE ARM PIVOTS THROUGH.
DESPITE SURFACE TEMPERATURES NEAR 50 AND BEGINNING A SLOW
FALL...STEEP MORNING LAPSE RATES AND TOTAL TOTALS 53 OR SO
SUGGEST STRONG ELEVATED INSTABILITY. THERE COULD BE POCKETS OF
VERY HEAVY RAIN TO THE E OF I-95 AS WELL. OUR FORECAST AREA WILL
BE GROUND ZERO FOR THE TRACK OF THE SURFACE LOW PRES AND CURRENT
THINKING IS THAT THE STRONGEST SURFACE WINDS WILL HOLD OFF UNTIL
WE GET ON THE BACK-SIDE OF THE LOW SUNDAY NIGHT.
THE INTENSE UPPER LOW AND POWERFUL VORTICITY FIELD WILL SHIFT NE
OF OUR FORECAST AREA AFTER 06Z SUNDAY. A BLEND OF THE GFS/ECMWF
SUGGEST OUR FORECAST TRENDS REMAIN REASONABLE WITH SOME TIMING
UNCERTAINTIES ON PCPN SWITCHOVER AND INTENSITY FROM 02Z TO 08Z.
THE BETTER CHANCE FOR SOME LIGHT SNOW ACCUMULATIONS CONTINUE
TO BE ALONG AND TO THE W OFF I-95 GIVEN HPC PROGS AND DECENT
PERSISTENCE FROM PREFERRED MODELS. SOUNDINGS SHIFT P-TYPE TO A
MAINLY SNOW APPEARANCE OVERNIGHT FOR MUCH OF OUR AREA WITH
DEEPEST MOISTURE AND FORCING W OF THE CAROLINA COASTAL PLAINS
AND UPSTATE CAROLINAS. VERY FEW CHANGES WERE MADE TO OUR PREVIOUS
FORECAST SINCE EVEN SLIGHT SHIFTS IN THE UPPER LOW COULD MAKE FOR
SIGNIFICANT DEVIATIONS IN WINTER WEATHER POTENTIAL. THERE IS ALSO
A CHANCE WE COULD SEE SOME LOCALLY STRONG N FLOW IN THE WAKE OF
THE COMPLEX LOW. WIND ADVISORIES NOT OUT OF THE QUESTION OVER
INLAND AND NORTHERN ZONES SUNDAY NIGHT. USERS ARE URGED TO PAY
CLOSE ATTENTION TO LATER FORECASTS FROM THE NATIONAL WEATHER
SERVICE OVER THE NEXT 36 HOURS. LAKE WIND ADVISORIES ARE A
LIKELIHOOD SUNDAY NIGHT INTO MON ON LAKE MOULTRIE.
LINGERING FLURRIES OR MIXING PCPN WILL END OVER CENTRAL SOUTH CAROLINA
BEFORE MIDDAY MON FOR THE MOST PART. SKIES GRADUALLY CLEARING FROM
THE SW. MON WILL BE VERY COLD AND BREEZY TO START THE DAY...NO
CHANGE TO HIGHS IN THE 40S ALL AREAS.
BELOW CLIMO TEMPS WILL TEMPER BY MID WEEK THEN A SIGNIFICANT WARMING
TREND. LOW TEMPERATURES TUE MORNING IN THE 20S AWAY FROM THE
IMMEDIATE COAST...RECORD LOWS AT BOTH CHARLESTON AND SAVANNAH ARE
UNLIKELY AT CHARLESTON AND SAVANNAH. DRY WEATHER ON TAP WITH PERIODS
OF UPPER LEVELS CLOUDS PERIODICALLY.
&&
.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
INITIAL LINE OF SHOWERS AND THUNDERSTORMS ASSOCIATED WITH THE LOW
PRESSURE SYSTEM TO THE WEST IS MAKING ITS WAY TOWARD THE COAST
FAIRLY QUICKLY. INTRODUCED LIGHT RAIN AT 1930Z FOR KCHS TERMINAL
THOUGH LIGHT SHOWERS CAN POSSIBLY MAKE IT IN A LOT SOONER.
POTENTIAL STRONG/SEVERE THUNDERSTORMS IS EXPECTED TO PEAK
OVERNIGHT AS UPPER DYNAMICS COMBINED WITH LOW LEVEL CONVERGENCE
CONTINUE TO BE QUITE IMPRESSIVE. THERE CONTINUES TO BE UNCERTAINTY
OF THE TIMING OF ANY BREAKS IN THE CONVECTION THUS WILL CONTINUE
MONITORING THE SITUATION AND UPDATE AS TRENDS BECOME MORE EVIDENT.
WINDS WILL CONTINUE TO BE GUSTY THROUGH LATE AFTERNOON. ALTHOUGH
HAVE GUSTINESS SUBSIDING BY MIDNIGHT...WINDS COULD GUST IN
ASSOCIATION WITH THE CONVECTION. AS FOR LOW LEVEL WIND SHEAR
OVERNIGHT...MODEL SOUNDINGS SUGGEST 30 TO 35 KNOTS. HAVE LEFT OUT
OF FORECAST AT THIS TIME DUE TO UNCERTAINTY OF THE SURFACE WINDS
DIMINISHING ENOUGH TO CREATE SHEAR CRITERIA. WILL REEVALUATE AT
THE NEXT TAF ISSUANCE.
EXTENDED AVIATION OUTLOOK...IFR/MVFR CIGS/VSBYS ARE EXPECTED
SUNDAY AND THROUGH SUNDAY NIGHT. TSTMS POSSIBLE SUN MORNING WITH
POTENTIAL FOR SMALL HAIL AND GUSTY WINDS. GUSTY NORTHERLY SURFACE
WINDS LIKELY LATE SUN INTO MON. AT THIS TIME WE ARE NOT EXPECTING
ACCUMULATING SNOWFALL AT EITHER AIRPORT SUNDAY NIGHT INTO MON
MORNING.
&&
.MARINE...
WINDS AND SEAS WILL BEGIN TO INCREASE FAIRLY QUICKLY LATE THIS
MORNING AS THE POWERFUL UPPER LOW MOVES CLOSER TO THE WATERS AND
THE LOW-LEVEL PRESSURE GRADIENT TIGHTENS. EXPECT SMALL CRAFT
ADVISORY SEAS TO IMPACT THE SC NEARSHORE WATERS AND GA OFFSHORE
WATERS THIS AFTERNOON. LOW-LEVEL JETTING SHOULD PRODUCE SMALL
CRAFT ADVISORY WINDS ALL WATERS THIS AFTERNOON. ADDED A SMALL
CRAFT ADVISORY FOR THE HARBOR UNTIL MIDNIGHT...AS THE
STRENGTHENING ONSHORE FLOW MAY BE ENHANCED BY THE SEA BREEZE
CIRCULATION.
VERY DIFFICULT WIND FORECAST ON SUNDAY WITH EVEN SMALL MODEL
DIFFERENCES PLAYING BIG OUTCOMES FOR WIND SPEEDS AND DIRECTION. WE
SETTLED FOR A GFS/ECWMF BLEND THAT ALLOWS VEERING SURFACE FLOW AS
THE FRONT MOVES E AND NE OF THE WATERS. SPEEDS STRONGEST OVER
GEORGIA WATERS S OF OSSABAW SOUND AND OVER OUR OUTER GEORGIA WATERS
BEYOND 20 NM. WINDS AND SEAS WILL BE TEETERING WITH SMALL CRAFT
ADVISORY CONDITIONS OVER WATERS WITHIN 20 NM FOR MUCH OF THE DAY.
IT IS LOOKING MORE PROBABLE THAT NEARLY ALL OF OUR COASTAL WATERS
COULD SEE A PERIOD OF GALES ON THE BACKSIDE OF THIS SYSTEM SUNDAY
NIGHT AFTER 09Z THROUGH MID MORNING MON. WITH A SYSTEM OF THIS
MAGNITUDE...STRONG WINDS AND VERY ROUGH SEAS APPEAR A CERTAINTY
AS IT EXITS THE CAROLINA COAST MON MORNING.
CONDITIONS WILL IMPROVED MON NIGHT INTO TUE NIGHT BUT WITH COLD AIR
AND STRONG THERMAL GRADIENTS PROVIDING A BIT STRONGER N FLOW THAN
MODELS CURRENTLY INDICATE. ADVISORIES COULD LINGER FOR OUR OUTER
GEORGIA WATERS UNTIL SOMETIME TUE MORNING.
