Area forecast discussion, Apr 4, 9:02 PM EDT, 4 hours 42 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
902 PM EDT MON APR 4 2011

.SYNOPSIS...
A STRONG COLD FRONT WILL CROSS OUR AREA FROM WEST TO EAST
TONIGHT...THEN BE OFF THE CAROLINA COAST BY TUESDAY AFTERNOON.  HIGH
PRESSURE WILL BUILD IN ACROSS THE REGION AND DOMINATE OUR WEATHER
THROUGH THE END OF THE WEEK.

&&

.NEAR TERM /THROUGH TUESDAY/...
FOR THE 00 UTC UPDATE I/VE SLOWED THE EASTWARD PROGRESSION OF THE
HIGH POPS. THE LINE OF STORMS HAS WEAKENED AND BECOME NEARLY
STATIONARY AS IT HAS ENTERED THE MTNS. THIS IS ABOUT WHAT WAS
EXPECTED...THOUGH IT/S SLOWED DOWN A BIT MORE THAN WHAT I EXPECTED.
MORE IMPORTANTLY...A LARGE BOWING LINE SEGMENT HAS DEVELOPED OVER NW
GA. BASED ON IT/S CURRENT RATE OF MOVEMENT...IT SHOULD MOVE INTO OUR
NE GA COUNTIES AROUND 0250 UTC...POSSIBLY SOONER IF IT ACCELERATES
MORE. WITH MUCAPE VALUES AROUND 1000 OVER THIS AREA...THE LINE
SHOULD HOLD TOGETHER.

PREVIOUS DISCUSSION...
GUSTY WINDS WILL CONTINUE INTO THE OVERNIGHT HOURS AS A STRONG COLD
FRONT MOVES INTO THE AREA. THEREFORE...WILL EXTEND THE WIND/LAKE
WIND ADV OVERNIGHT AS WELL. GENERAL THOUGHTS FROM THE PREVIOUS FCST
STILL ON TRACK. SOME ISOLATED TO SCT CONVECTION POSSIBLE OVER THE NC
MTNS THIS AFTERNOON BEFORE QLCS SQUALL LINE AHEAD OF A STRONG COLD
FRONT MOVES INTO THE MTNS THIS EVENING...THEN TO A HKY-GSP-GRD LINE
AROUND MIDNIGHT...THEN I-77 CORRIDOR BEFORE DAYBREAK...THEN EAST OF
THE AREA AROUND 12Z. ALL THE GUIDANCE HAS AT LEAST SOME CAPE WITH
THE NAM A SEEMINGLY STRONG OUTLIER. STILL...THE SREF MEAN MUCAPE HAS
VALUES 500 OR BETTER ALONG THE LINE AND MIXED LAYER CAPE SLIGHTLY
LESS. THE SREF ALSO SHOWS MEDIAN BULK SHEAR 60 TO 80 KNOTS AND 0-1KM
HELICITY VALUES FROM 100 TO 300. GIVEN THESE FACTORS IT LOOKS LIKELY
THAT A SEVERE STORMS WILL DEVELOP AS THIS LINE MOVES THRU THE CWFA.
HAVE ALREADY INCLUDED ISOLATED SEVERE STORMS WITH DAMAGING WIND
WORDING IN THE GRIDS. LOWS SHOULD BE AROUND 10 DEGREES ABOVE NORMAL.

THE FRONT QUICKLY MOVES EAST OF THE AREA TUE MORNING...TAKING THE
SQUALL LINE WITH IT. HAVE QUICKLY ENDED POP FROM WEST TO EAST OVER
THE AREA. NW FLOW AND LOW LEVEL LINGER OVER THE MTNS...SO HAVE
LIKELY POP DIMINISHING TO SLIGHT CHC FOR THE AFTERNOON. CANNOT RULE
OUT SOME SNOW FOR THE HIGHEST PEAKS...BUT NO SIGNIFICANT ACCUMS
EXPECTED. STRONG WINDS WILL CONTINUE THRU AT LEAST EARLY AFTERNOON.
FOR NOW...WILL NOT EXTEND ANY WIND ADV INTO TUE. HOWEVER...LATER
SHIFTS WILL LIKELY NEED SOMETHING FOR THIS PERIOD. HIGHS 5 TO 10
DEGREES BELOW NORMAL.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
AS OF 200 PM MONDAY...SHORT TERM WEATHER WILL BE QUIET AS AN
UPPER RIDGE BUILDS OVER THE SE U.S. THROUGH THU. SURFACE HIGH
PRESSURE CENTERED TO THE SW OF THE AREA TUE NIGHT WILL TRANSITION TO
OFF THE EAST COAST BY LATE WED AND REMAIN THERE THROUGH THE SHORT
TERM. THE ONLY WEATHER CONCERN WILL BE THE COLD TEMPS FORECAST FOR
TUE NIGHT. DRY ATMOSPHERE AND LIGHT WINDS WILL PROMOTE IDEAL
RADIATIONAL COOLING. CURRENT MIN TEMP GRID HAS TEMPS BELOW FREEZING
OVER ALL THE MOUNTAINS...WITH FOOTHILLS AND PIEDMONT MIN TEMPS
GENERALLY IN THE MID 30S. HENCE...WILL HOIST A FREEZE WATCH FOR THE
MOUNTAINS FOR TUE NIGHT. PATCHY FROST IS A GOOD BET OVER MOST
FOOTHILL/PIEDMONT LOCATIONS TUE NIGHT...ESPECIALLY LOW LYING AREAS.
OTHERWISE...GENERALLY CLEAR CONDITIONS WITH SLOWLY WARMING TEMPS.
STAYED CLOSE TO A MOS BLEND FOR TEMPS.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AS OF 140 PM MONDAY...THE MEDIUM RANGE MODEL OF CHOICE IS THE ECMWF.
THERE ARE SOME BIG TIMING DIFFERENCES BETWEEN THE GFS AND ECMWF AND
THE GFS IS FOR THE MOST PART CONSIDERED AN OUTLIER MODEL.  SOUTHERLY
FLOW AND INSTABILITY WILL RESULT IN AN INCREASE OF SHOWERS AND
STORMS ON FRIDAY AFTERNOON...ESPECIALLY IN THE MOUNTAINS.  HIGH
TEMPERATURES WILL BE ABOUT TEN DEGREES ABOVE NORMAL.  A LULL IS
EXPECTED FRIDAY NIGHT INTO SATURDAY MORNING WITH MORE STABILITY AND
NO FOCUS MECHANISM.  THE ECMWF SHOWS A MESOSCALE CONVECTIVE SYSTEM
LEAVING OKLAHOMA FRIDAY EVENING AND REACHING THE UPPER TENNESSEE AND
OHIO VALLEYS SATURDAY AFTERNOON.  IF THIS PANS OUT...WE WILL GET THE
SOUTHERN END OF THE PASSAGE OF THIS AS IT TRACKS ACROSS THE
VIRGINIAS SATURDAY NIGHT.  WE WILL THEN BE UNDER OR NEAR THE AXIS OF
THE UPPER RIDGE LATE SUNDAY INTO MUCH OF SUNDAY NIGHT AND VERY
LITTLE CONVECTION.  THE NEXT FRONT WILL BE APPROACHING ACROSS
TENNESSEE ON MONDAY AND VERY SLOWLY REACHING OUR AREA LATE MONDAY
AND INTO MONDAY NIGHT.  THE DYNAMICS WILL BE PASSING WELL NORTH AND
THE FRONT TENDS TO WASH OUT AS IT CROSSES FROM NW TO SE LATE MONDAY
NIGHT.

&&

.AVIATION /01Z TUESDAY THROUGH SATURDAY/...
AT KCLT...STRONG THUNDERSTORMS WILL ORGANIZE OVER NRN GA AND AL THIS
EVENING AND THEN SPRINT TO THE NE OVERNIGHT. ATTM I EXPECT THE
STORMS TO AFFECT THE AIRFIELD BETWEEN ABOUT 7 AND 10 UTC...THOUGH
THAT WILL PROBABLY CHANGE A LITTLE ONCE THE UPSTREAM LINE BECOMES
MORE ORGANIZED AND WE GET A BETTER HANDLE ON IT/S MOVEMENT.
CONDITIONS SHOULD BE QUITE WINDY TONIGHT AND TUESDAY. I HAVE THE
WIND SHIFT TRAILING THE LINE...BUT ONCE THE STORMS COME
THROUGH...WINDS WILL BE QUITE ERRATIC. THE STORMS WILL GIVE WAY TO A
PERIOD OF LIGHTER RAIN AND THEN CLEARING BY MID TO LATE MORNING WITH
A FROPA. THERE WILL ALSO BE LOW LEVEL WIND SHEAR TONIGHT AS THE LOW
LEVEL WINDS WILL BE QUITE STRONG AHEAD OF THE FRONT.

ELSEWHERE...THUNDERSTORMS HAVE MOVED INTO THE NC MTNS...AND SHOULD
AFFECT KAVL WITHIN THE HOUR. THESE STORMS WILL BE VERY SLOW TO MOVE
EASTWARD...AND WE WILL PROBABLY HAVE TO WAIT FOR STRONGER STORMS TO
MOVE OUT OF NRN GA A LITTLE AFTER MIDNIGHT BEFORE THE FOOTHILL AND
PIEDMONT TAF SITES SEE ANYTHING. THESE STORMS SHOULD MOVE QUITE FAST
AND WILL PRODUCE A COUPLE HOURS OF SIGNIFICANT VSBY AND CIG
REDUCTIONS. A PERIOD OF IFR CIGS IS EXPECTED TO DEVELOP BEHIND THE
LINE FOR A COUPLE HOURS BEFORE THE COLD FRONT CROSSES THE
REGION...TURNING THE WINDS OUT OF THE NW AND BRINGING CLEARING SKIES.

OUTLOOK...CONDITIONS SHOULD BE VFR TUE AFTERNOON INTO FRIDAY. SOME
RESTRICTIONS ARE POSSIBLE AGAIN LATE FRIDAY AS A FRONT DROPS DOWN
INTO THE AREA.

&&

.FIRE WEATHER...
S FUEL MOISTURE REMAINS LOW...AND SUSTAINED WINDS ARE STILL IN IN
THE 15 TO 25 MPH RANGE WITH GUSTS WELL OVER 30 MPH...A FIRE DANGER
STATEMENT REMAINS IN EFFECT THROUGH THE REMAINDER OF TODAY FOR NORTH
CAROLINA AND NORTHEAST GEORGIA.
