Area forecast discussion, Sep 30, 3:45 AM EDT, 7 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
345 AM EDT FRI SEP 30 2011
.SYNOPSIS...
A STRONG COLD FRONT WILL MOVE THROUGH THE REGION LATE THIS
AFTERNOON AND THIS EVENING. HIGH PRESSURE WILL THEN PROVIDE A
DRIER AND MUCH COOLER AIRMASS THIS WEEKEND INTO MUCH OF NEXT
WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
IN ADVANCE OF AN APPROACHING COLD FRONT...INSOLATION...W/SW WINDS
AND COMPRESSIONAL HEATING/850 MB TEMPERATURES AROUND 14C WILL
SUPPORT HIGH TEMPERATURES AROUND 90F TODAY.
MEANWHILE...EARLY FRIDAY MORNING WATER VAPOR IMAGERY DEPICTED AN
IMPRESSIVE UPPER TROUGH DIGGING S/E INTO THE OHIO VALLEY. THE LEAD
SHORTWAVE WILL HELP DRIVE A STRONG SURFACE COLD FRONT THROUGH THE
REGION LATE THIS AFTERNOON/THIS EVENING. AHEAD OF THESE FEATURES...
00Z NAM/GFS GUIDANCE CONTINUE TO PRODUCE THUNDERSTORMS OVER
NORTHERN COUNTIES LATE THIS AFTERNOON/EARLY THIS EVENING. IN THIS
AREA...LOW LEVEL CONVERGENCE/UPPER LEVEL DIVERGENCE WILL COINCIDE
WITH AN AXIS OF INSTABILITY/STRENGTHENING 0-6 KM BULK SHEAR. THE
ENVIRONMENT WILL REMAIN QUITE DRY...SO COLD FROPA COULD OCCUR WITH
NO PRECIPITATION. HOWEVER...GIVEN GUIDANCE TRENDS SLIGHT CHANCE
POPS ARE JUSTIFIED ACROSS NORTHERN COUNTIES LATE AFTERNOON INTO
EARLY EVENING.
FORCING FOR ASCENT...DOWNDRAFT CAPES EXCEEDING 1000 J/KG AND
COOLING MID LEVELS SUGGEST THE POTENTIAL FOR ISOLATED DAMAGING
WIND GUSTS/LARGE HAIL. HOWEVER...THE LOW PROBABILITY FOR ANY
THUNDERSTORMS WILL PRECLUDE ANY MENTION OF SEVERE WEATHER WITHIN
THE HAZARDOUS WEATHER OUTLOOK WITH THE EARLY MORNING FORECAST
PACKAGE.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/...
STRONG COLD FROPA WILL USHER DRIER AND MUCH COOLER AIR INTO THE
REGION TONIGHT. BY DAYBREAK SATURDAY...TEMPERATURES WILL RANGE
FROM THE UPPER 40S INLAND TO THE 50S AT THE COAST.
A MUCH COOLER AND DRIER AIRMASS WILL BUILD INTO THE REGION SATURDAY
THROUGH MONDAY. THE COLD ADVECTION WILL BE SLIGHTLY OFFSET BY
DOWNSLOPE COMPRESSIONAL WARMING DURING THE PERIOD...ALLOWING HIGH
TEMPERATURES TO REACH INTO THE LOWER TO MIDDLE 70S. OVERNIGHT LOWS
WILL PLUMMET AFTER SUNSET EACH EVENING WITH THE COLDEST TEMPS
EXPECTED SATURDAY NIGHT. IT DOES NOT LOOK LIKE THE BOUNDARY LAYER
WILL COMPLETELY DECOUPLE SATURDAY NIGHT SO INLAND TEMPS WILL
PROBABLY STAY ABOVE 40F.
LAKE WINDS...ISSUED A LAKE WIND ADVISORY FOR TONIGHT/SATURDAY
MORNING AS MUCH COOLER AIR FLOWS ACROSS THE WARM WATERS OF LAKE
MOULTRIE.
&&
.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
HIGH PRESSURE WILL CONTINUE TO MODIFY AND DRIFT EAST TOWARD THE
MID-ATLANTIC REGION DURING THE LONG-TERM PERIOD. A WEAK COASTAL
TROUGH MAY DEVELOP LATE IN THE WEEK WHICH COULD ALLOW FOR A FEW
SHOWERS OVER THE COASTAL WATERS OR IMMEDIATE COASTAL AREAS. AT THIS
POINT WE KEPT DRY CONDITIONS IN THE FORECAST. HIGHS WILL GENERALLY
BE IN THE UPPER 70S WITH LOWS IN THE 50S.
&&
.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
VFR EXPECTED THROUGH THIS EVENING. A FEW THUNDERSTORMS COULD
DEVELOP IN THE KCHS VICINITY LATE AFTERNOON/EARLY EVENING...BUT
THE PROBABILITY REMAINS TOO LOW TO JUSTIFY A MENTION OF CBS WITHIN
THE 06Z TAF. MEANWHILE...WITH A DEEPENING MIXED LAYER WIND GUSTS
15-20 KT WILL OCCUR THIS AFTERNOON. COLD FROPA WILL THEN PRODUCE A
WIND SHIFT TO THE NORTHWEST AFTER 00Z/PRIOR TO 06Z.
EXTENDED AVIATION OUTLOOK...VFR.
&&
.MARINE...
AHEAD OF AN APPROACHING STRONG COLD FRONT...W/SW WINDS WILL
AVERAGE 10-15 KT ACROSS COASTAL WATERS TODAY. SEAS WILL REMAIN IN
THE 2-3 FT RANGE THROUGH THE DAY.
TONIGHT...STRONG COLD FROPA WILL PRODUCE A SHARP WIND SHIFT TO
THE N/NW THIS EVENING...AND MARINE BOUNDARY LAYER INSTABILITY WILL
INCREASE AS A MUCH COOLER AIRMASS SURGES OVER THE WARM COASTAL
WATERS. EFFICIENT MIXING THROUGH A LAYER OF 25-30 KT WINDS WILL
SUPPORT 25-30 KT GUSTS AT THE SURFACE...AND SEAS WILL BUILD TO AS
HIGH AS 4-5 FT WITHIN NEARSHORE WATERS AND 6-7 FT BEYOND 20 NM.
THUS...ISSUED SMALL CRAFT ADVISORIES FOR ALL COASTAL WATERS.
THE INITIAL SURGE AFTER THE COLD FRONT LATE TONIGHT WILL SETTLE DOWN
PRETTY QUICKLY ON SATURDAY WITH SMALL CRAFT ADVISORIES DROPPING OFF
AT 11 AM EVERYWHERE EXCEPT THE OFFSHORE GA WATERS WHICH COME DOWN
LATE SATURDAY AFTERNOON DUE TO RESIDUAL 6 FT SEAS.
WINDS/SEAS WILL REMAIN SOMEWHAT ELEVATED THROUGH TUESDAY DUE TO
DECENT LOW-LEVEL WINDS AND FAVORABLE MIXING PROFILES IN COLD
ADVECTION.
