AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
153 PM EDT MON SEP 22 2014

.SYNOPSIS...
A COLD FRONT WILL ADVANCE THROUGH THE REGION TODAY AND TONIGHT
BEFORE STALLING SOUTH OF THE AREA. HIGH PRESSURE WILL BUILD IN FROM
THE NORTH THROUGH NEXT WEEKEND WHILE A TROUGH OF LOW PRESSURE
STRENGTHENS NEAR THE COAST.

&&

.NEAR TERM /THROUGH TONIGHT/...
EARLY THIS AFTERNOON...FORECAST IS ON TRACK AND
SHOWERS/THUNDERSTORMS ARE STARTING TO MOVE INTO THE FAR INLAND
SOUTHEAST GEORGIA ZONES. PREVIOUS DISCUSSION FOLLOWS BELOW.

LATE THIS MORNING...RADAR IMAGERY SHOWS SHOWERS ACROSS THE
MIDLANDS ALONG AN APPROACHING COLD FRONT THAT ARE SO FAR STAYING
JUST OUT OF THE FORECAST AREA. THE FRONT AND AN AMPLIFYING UPPER
LEVEL PATTERN WILL BE THE MAIN FORECAST DRIVERS TODAY. ALOFT...THE
SHARP MID/UPPER LEVEL SHORTWAVE IS VERY PROMINENT ON WATER VAPOR
IMAGERY AS IT DIGS INTO THE TENNESSEE VALLEY...THE SOUTHERN
APPALACHIANS...AND THE DEEP SOUTH. THIS FEATURE IS PROGGED TO
CONTINUE TO QUICKLY DIG SOUTHEASTWARD...EVEN TAKING ON A MORE
NEUTRAL AND EVEN SLIGHTLY NEGATIVE TILT ALONG ITS AXIS. IT MAY
EVEN CLOSE OFF INTO AN UPPER LOW...THOUGH THIS WILL MORE THAN
LIKELY OCCUR OVERNIGHT. AT THE SURFACE...THE COLD FRONT STRETCHES
ACROSS CENTRAL GEORGIA AND THE CAROLINAS AND WILL CONTINUE TO BE
PUSHED BY AN EXPANSIVE AREA OF HIGH PRESSURE ACROSS THE UPPER
MIDWEST. THE MAIN FORECAST ISSUES FOR TODAY ARE CENTERED AROUND
THE DEVELOPMENT OF THUNDERSTORMS ALONG THE FRONT...THEIR
TIMING...AND THE SEVERE WEATHER POTENTIAL.

THE NEAR TERM HI-RES MODELS APPEAR TO HAVE A REASONABLE HANDLE ON
CURRENT CONDITIONS AND SHOW CONVECTIVE INITIATION ACROSS THE
INLAND SOUTHEAST GEORGIA ZONES AROUND 18Z. THIS ACTIVITY WILL THEN
EXPAND SOUTH AND EASTWARD THROUGH 21Z...WHEN THE COVERAGE IS
EXPECTED TO BE HIGHEST. THEN BY THE EVENING...MUCH OF THE ACTIVITY
WILL BE ALONG THE COAST LIKELY FOLLOWING OUTFLOW BOUNDARIES AS
THEY FAN OUT TO THE SOUTH AND EAST. NO SIGNIFICANT CHANGES HAVE
BEEN MADE TO THE ONGOING POP SCHEME...WHICH STILL LOOKS TO BE IN
GOOD SHAPE WHEN COMPARED TO LATEST AVAILABLE GUIDANCE.

THE NEXT BIG FORECAST QUESTION THEN DEALS WITH THE POTENTIAL FOR
SEVERE THUNDERSTORMS. VISIBLE SATELLITE IMAGERY SHOWS PLENTY OF
CLEAR SKIES AHEAD OF THE FRONT ACROSS THE FORECAST AREA...WHICH
WILL LEAD TO GOOD SURFACE HEATING THIS AFTERNOON. OVERALL
THOUGH...IT APPEARS THAT INSTABILITY WILL BE MORE ASSOCIATED WITH
MID/UPPER LEVEL COOLING WITH THE ARRIVAL OF THE UPPER WAVE THAN IT
WILL WITH SURFACE PROCESSES DUE TO SOME DRIER LOW LEVEL AIR. 500
MB TEMPS THIS MORNING ARE AROUND -8C...AND ARE EXPECTED TO COOL TO
AROUND -10 OR -11 BY THE LATE AFTERNOON HOURS. EVEN STILL...CAPE
VALUES APPEAR TO BE LIMITED IN THE 1500-2000 J/KG RANGE THANKS TO
A DRY SUB-CLOUD LAYER AND DEWPOINTS ONLY IN THE MID/UPPER 60S.
THERE IS A GOOD AMOUNT OF MID LEVEL DRY AIR WHICH RESULTS IN DCAPE
VALUES AROUND 900-1000 J/KG. ALSO...WINDS THROUGH THE LOWEST 6 KFT
AREN/T ALL THAT IMPRESSIVE...ESPECIALLY AT 700 MB WHERE THEY ARE
PROGGED TO ONLY BE AROUND 10-15 KT THIS AFTERNOON. INSTEAD THE
BULK OF THE SHEAR IS PROVIDED BY INCREASING 500 MB FLOW AS THE
SHORTWAVE DIGS INTO THE AREA. SO 0-6 KM SHEAR INCREASES TO THE
30-40 KT RANGE BY THE MID AFTERNOON. WHILE DAMAGING WIND GUSTS ARE
THE MAIN SEVERE THREAT...HAIL IS ALSO A POSSIBILITY. THE CURRENT
FREEZING LEVEL IS AROUND 14 KFT BUT IS EXPECTED TO DROP TO AROUND
13 KFT BY THE AFTERNOON...WITH A DECENT SEPARATION TO THE WET BULB
ZERO HEIGHT AROUND 10-11 KFT. SO LARGE HAIL IS POSSIBLE...BUT
CERTAINLY A SECONDARY CONCERN TO THE WIND THREAT. OVERALL...SOME
OF THE LIMITING FACTORS DISCUSSED ARE EXPECTED TO KEEP THE SEVERE
THREAT ISOLATED WITH A MAIN TIME PERIOD OF CONCERN BETWEEN 3 PM
AND 9 PM.

TONIGHT...WE MADE SOME CHANGES WITH THE UPPER SHORT WAVE TROUGH
SLOWING AND CUTTING OFF. WE INCREASED OVERNIGHT RAIN CHANCES MANY
AREAS AFTER LIKELY EVENING POPS OVER EASTERN AND SOUTHERN ZONES.
LIGHTER RAINS MAY LINGER THROUGH THE NIGHT WITH COOL NE WINDS AT
THE SURFACE. LOWS IN THE 60-65 RANGE.

&&

.SHORT TERM /TUESDAY THROUGH THURSDAY/...
THE UPPER SHORTWAVE IS EXPECTED TO CLOSE OFF AND STALL OVER THE
CAROLINAS TUESDAY AND WEDNESDAY WHILE A COASTAL TROUGH STRENGTHENS
ALONG THE SOUTHEAST COAST. ALTHOUGH THE GFS HAS COME INTO BETTER
AGREEMENT WITH THE ECMWF REGARDING THE UPPER LOW CUTTING OFF...THE
ECMWF REMAINS QUITE A BIT WETTER. THE EURO APPEARS A BIT TOO BULLISH
WITH BRINGING THE COASTAL TROUGH INLAND BY WEDNESDAY MORNING. WE
STUCK CLOSER TO THE GFS FOR THIS PACKAGE...KEEPING FAIRLY HIGH RAIN
CHANCES OVER THE COASTAL WATERS WITH RAPIDLY DIMINISHING POPS AS ONE
MOVES INLAND. WE SHOW A BIT MORE INLAND COVERAGE ON THURSDAY TO
ACCOUNT FOR THE TROUGH POTENTIALLY SHIFTING INLAND.

COLD ADVECTION WITH HIGH PRESSURE BUILDING IN FROM THE NORTH AND
EXTENSIVE CLOUDINESS DUE TO ISENTROPIC ASCENT WILL YIELD A COOLING
TREND DURING THE PERIOD. HIGHS ON TUESDAY SHOULD REACH THE LOWER 80S
BUT BY THURSDAY READINGS WILL BE IN THE MIDDLE 70S DURING THE DAY.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
PERHAPS ONE OF THE LONGEST HIGH PRESSURE WEDGE PATTERNS IS IN STORE
FOR THE MEDIUM TO LONG RANGE PERIODS. THE EXPANSIVE SURFACE HIGH
OVER THE NORTHEAST STATES LOOKS TO REMAIN IN PLACE THROUGH SATURDAY
NIGHT WHILE A COASTAL TROUGH MAINTAINS CONSIDERABLE CLOUDINESS...
BETTER RAIN CHANCES AND COOL TEMPS. SUNDAY INTO MONDAY THERE ARE
LARGE MODEL DIFFERENCES REGARDING THE POTENTIAL FOR A DEEP LONGWAVE
UPPER TROUGH MOVING INTO THE EASTERN UNITED STATES. A GULF LOW
PRESSURE SYSTEM MAY LIFT NORTHEAST LATE IN THE WEEKEND OR EARLY NEXT
WEEK.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
THE MAIN FORECAST PROBLEM THIS AFTERNOON AND EVENING IS THE
POTENTIAL FOR DIRECT IMPACTS FROM THUNDERSTORMS ASSOCIATED WITH A
COLD FRONT. THE TIMES FOR TEMPO THUNDER REDUCING VISIBILITIES AND
CAUSING GUSTY WINDS HAVE BEEN ADJUSTED BASED ON CURRENT RADAR AND
MODEL TRENDS. KSAV APPEARS TO HAVE THE BEST CHANCE TO SEE IFR
CONDITIONS FOR A BRIEF PERIOD AS THE THUNDERSTORM COVERAGE WILL
LIKELY BE BETTER THERE. BUT...CONFIDENCE ISN/T QUITE HIGH ENOUGH
SO BOTH SITES ARE KEPT IN THE MVFR RANGE FOR THUNDERSTORM
CONDITIONS. ONCE THUNDERSTORMS MOVE OFF THE COAST AND DISSIPATE
THIS EVENING...STRATIFORM RAIN WILL LIKELY DEVELOP AND LINGER
AROUND THE REGION FOR MUCH OF THE OVERNIGHT. THERE ARE SOME
SIGNALS IN THE MODEL DATA THAT PREVAILING MVFR OR LOWER CEILINGS
COULD OCCUR LATE TONIGHT AND INTO TUESDAY MORNING...BUT CONFIDENCE
ISN/T YET HIGH ENOUGH TO INTRODUCE INTO THE FORECAST.
INSTEAD...WILL GO WITH VFR CEILINGS AND STRENGTHENING NORTHEAST
WINDS FOR THE LATTER PART OF THE FORECAST AS A WEDGE OF HIGH
PRESSURE BEGINS TO BUILD INTO THE REGION.

EXTENDED AVIATION OUTLOOK...BRIEF FLIGHT RESTRICTIONS POSSIBLE IN
SCATTERED SHOWERS TUESDAY THROUGH FRIDAY. CHANCES FOR MVFR CEILINGS
INCREASE THURSDAY INTO FRIDAY AS LOW PRESSURE STRENGTHENS OFF THE
COAST.

&&

.MARINE...
TODAY...WINDS SHOULD LAY DOWN AS THE SURFACE FRONTAL TROUGH NEARS.
STRONG TSTMS ARE POSSIBLE LATER TODAY OR THIS EVENING ACROSS THE
MARINE WATERS...ESPECIALLY SOUTH OF CHARLESTON. IF SOME OF THE
HIGHER RESOLUTION MODELS ARE CORRECT...THE THREAT FROM TSTM WINDS
COULD BE SIGNIFICANT IF THEY ORGANIZE.

THE SYNOPTIC FLOW WILL SHIFT NORTH AND THEN NORTHEAST TONIGHT WITH
SURGING BUILDING THE FLOW CLOSE TO 20 KT OVER MUCH OF THE MARINE
AREA BY DAWN ON TUESDAY. SEAS WILL BUILD TONIGHT TO 3 TO 5 FT.

A PROLONGED NORTHEAST FLOW WILL EXIST FROM TUESDAY INTO NEXT WEEKEND
AS BROAD HIGH PRESSURE BUILDS FROM THE NORTH AND A COASTAL TROUGH
DEVELOPS. THE BEST GRADIENT AND SURGE IS ANTICIPATED TUESDAY INTO
WEDNESDAY DURING WHICH SMALL CRAFT ADVISORIES ARE LIKELY FOR MOST IF
NOT ALL OF THE COASTAL WATERS. LATE IN THE WEEK INTO THE WEEKEND WE
MAY STILL BE FLIRTING WITH SOME 6 FT SEAS AND 25 KT WIND GUSTS
THOUGH THE OVERALL GRADIENT LOOKS A BIT WEAKER.

&&

.TIDES/COASTAL FLOODING...
INCREASING NORTHEAST FLOW TUESDAY THROUGH NEXT WEEKEND WILL RESULT
IN MODERATE CHANCES FOR SHALLOW COASTAL FLOODING ALONG THE COAST
ESPECIALLY THE SC COAST INCLUDING DOWNTOWN CHARLESTON AROUND THE
TIMES OF HIGH TIDE.
