AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
127 AM EDT FRI MAY 9 2008

.SYNOPSIS...
A COLD FRONT WILL MOVE INTO THE REGION TONIGHT AND THEN STALL OUT ON
FRIDAY. WEAK HIGH PRESSURE WILL TEMPORARILY PUSH THIS FRONT SOUTH OF
THE AREA ON SATURDAY BEFORE RETURNING NORTH AS A WARM FRONT ON
SUNDAY. DRY NORTHWEST FLOW WILL THEN FOLLOW FOR EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH TODAY/...
SHOWERS WITH SCT TSTMS WILL CONTINUE TO MOVE EAST ACROSS THE
FOOTHILLS AND PIEDMONT THROUGH THE EARLY MORNING HOURS...BEFORE
WINDS VEERING WESTERLY ADVECT IN DRIER AIR AND DIMINISH ACTIVITY IN
DOWNSLOPE FLOW. MOIST LOW LEVELS AND CONTINUED CLOUD COVER WILL KEEP
MINS TO THE WARMER SIDE OF MOS. THE DEEPER MOISTURE BAND SHOULD
CLEAR THE AREA BY 12Z FRI ALONG WITH ANY RESIDUAL PRECIP. DOWNSLOPE
FLOW SHOULD QUICKLY SCOUR CLOUDS WITH CLEARING CONDITIONS BY MID
MORNING FRI.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
AS OF 320 PM THURSDAY...BY FRIDAY AFTERNOON THE COLD FRONT SHOULD
BECOME STATIONARY NEAR THE NC/SC STATE LINE. I EXPECT THAT THE
FRONTAL PRECIPITATION WOULD PUSH EAST OF THE CWA BY FRIDAY
AFTERNOON. HOWEVER...A FEW LINGERING CONVECTIVE SHRA/TSRA MAY REMAIN
NEAR THE TN LINE. MILD LLVL THICKNESSES AND INCREASING INSOLATION
SHOULD TEMPERATURES IN THE MID 70S IN THE MTNS AND L80S EAST.

FRIDAY NIGHT...A DECENT S/W WILL RIPPLE ACROSS KY/TN WITH THE SFC
REFLECTION MOVING OVER THE SOUTHERN APPALACHIANS. LINGERING
INSTABILITY AND MARGINAL SYNOPTIC LIFT MAY SUPPORT SCT SHRA/TSRA
DURING THE PRE-DAWN HOURS. AFTER SUNRISE SAT...DRY HIGH PRESSURE
WILL NOSE SOUTHWARD ACROSS THE CWA. INSTABILITY SHOULD BECOME
INCREASINGLY LIMITED ACROSS NC THROUGH THE MORNING...PUSHING
INSTABILITY FURTHER SOUTH ACROSS SC DURING THE AFTERNOON.

SATURDAY NIGHT...THE CENTER OF HIGH PRESSURE WILL SHIFT OVER THE
ATLANTIC AS ANOTHER LOW PRESSURE SYSTEM ORGANIZES ACROSS THE MID
WEST. HIGH PRESSURE SHOULD CONTINUE TO NOSE ACROSS THE CWA THROUGH
THE DAY. HOWEVER...A WARM FRONT ASSOCIATED WITH THE LOW IS FORECAST
TO ROTATE NORTH ACROSS THE SOUTHERN APPALACHIANS SUN MORNING AND
AFTERNOON. THE WARM FRONT WILL STRUGGLE TO OVERCOME A WEAK IN-SITU
AREA CAD...KEEPING TEMPS ACROSS THE NC FOOTHILLS AND PIEDMONT
LIMITED TO AROUND 70. HOWEVER...THE UPPER SAVANNAH RIVER VALLEY AND
THE EASTERN UPSTATE MAY EMERGE OUT OF THE CAD DURING THE LATE
AFTERNOON. ALLOWING CAPE TO BUILD TO 1000 J/KG ALONG WITH VEERING
LLVL WIND FIELDS. ALONG AND EAST OF THE WEDGE BOUNDARY COULD SEE A
FEW STRONG TO SEVERE TSRA DURING THE AFTERNOON. A SIGNIFICANT COLD
FRONT SHOULD SWEEP ACROSS THE REGION DURING THE LATE AFTERNOON AND
EARLY EVENING. IT IS UNCERTAIN THAT ENOUGH INSTABILITY WILL REMAIN
AHEAD OF THE COLD FRONT TO SUPPORT A LINEAR MCS. IT DOES APPEAR THAT
THE TN BORDER AREAS WILL SEE THE STRONGEST CONVECTION AS THE STORMS
WILL ORIGINATE FROM THE WARM SECTOR ACROSS TN. SUN AFTERNOON AND
EVENING IS OUTLOOKED FOR POSSIBLE SEVERE TS IN SPCS DY4.

SUNDAY NIGHT...WIND FIELDS FROM THE SFC TO 1 KM WILL STRENGTHEN
SIGNIFICANTLY IN THE WAKE OF THE FRONT. IN FACT...H8 WINDS BRIEFLY
REACH 50-60 KTS ON THE GFS LATE SUNDAY NIGHT. I WILL INCREASE WINDS
ACROSS THE CWA AND INDICATE GUSTS RANGING FROM 25-30 KTS ACROSS THE
MTNS. IN ADDITION...STRONG CAA COULD BRING H85 TEMPS ACROSS THE TN
LINE TO 0C BY 12Z MON. USING A BLEND OF NATIONAL GUIDANCE AND GMOS I
WILL PAINT THE MTNS WITH TEMPS MAINLY IN THE 40S.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
AS OF 315 PM THURSDAY...OVERALL THE 12Z GFS AND THE 00Z ECMWF AGREE
ON THE GENERAL PICTURE MON THROUGH THURS. MON MORNING BEGINS WITH
CLOSED UPPER LOW OVER THE MID ATLANTIC...WHICH MAKES LITTLE EASTWARD
PROGRESS THROUGHOUT THE DAY. MON SHOULD BE RELATIVELY DRY AND BREEZY
WITH GOOD PRESSURE GRADIENT IN PLACE ACROSS THE FA. WILL CARRY SOME
CHC POPS MAINLY ACROSS THE EAST TO ACCOUNT FOR THE POSSIBILITY OF
LINGERING SHOWERS. HEIGHTS RISE TUES AS UPPER RIDGE OVER THE MIDWEST
BEGINS TO NOSE IN AND THE UPPER LOW GRADUALLY MOVES OFF THE EAST
COAST. TEMPS WARM 7 TO 8 DEGREES IN RESPONSE TO THE INCOMING RIDGE.
CONTINUED DRY TUES NIGHT THROUGH EARLY WED AS UPPER RIDGE CONTINUES
TO TRANSLATE ACROSS THE EASTERN CONUS. NEXT SYSTEM BEGINS TAKING
SHAPE EARLY WED AS UPPER LEVEL DISTURBANCE AND SURFACE LOW MOVE OUT
OF THE PLAINS. THE GFS AND THE ECMWF DIFFER A BIT WITH THE HANDLING
OF THIS SYSTEM BUT BOTH SHOW THE DEVELOPMENT OF A RATHER STRONG COLD
FRONT POISED TO CROSS THE FA LATE WED. PERFECT PROG OF MODEL FIELDS
ALSO SHOWS THE POTENTIAL FOR A SEVERE WEATHER EVENT WED AFTERNOON
AND EVENING. THE GFS SHOWS 1000-1500 J/KG OF CAPE AND DEEP LAYER
SHEAR IN EXCESS OF 60 KTS AS THE FRONT CROSSES THE AREA. COOLER AIR
MOVES IN FOR THE LATTER PART OF THE WEEK AS BOTH MODELS CARVE OUT A
RATHER LARGE EAST COAST TROUGH. FOR NOW WILL ONLY CARRY CHC POPS WED
THROUGH THUR TO ACCOUNT FOR SOME UNCERTAINTY AT THE BACK END OF THE
FORECAST PERIOD.

&&

.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
THUNDERSTORM COVERAGE HAS DIMINISHED AS UPPER FORCING MOVES
NORTHEAST OF THE AREA BUT ADDITIONAL LOW LEVEL CONVERGENCE WILL
BRING SHOWERS FROM THE SOUTHWEST. A FEW THUNDERSTORMS ARE STILL
POSSIBLE FOR THE EARLY MORNING HOURS. MODEL GUIDANCE HAS BACKED OFF
ON EXTENT OF MVFR CIGS THAT COULD DEVELOP LATE TONIGHT SO JUST WENT
SCT MVFR LAYER ATTM. AN INCREASING WESTERLY DOWNSLOPE FLOW WILL
ALLOW CLEARING OF RESIDUAL LOW CLOUDS AFTER DAYBREAK...WITH GUSTY
WEST WINDS DEVELOPING THROUGH THE AFTERNOON.

OUTLOOK...VFR CONDITIONS THROUGH SAT WITH SOME MVFR CLOUDS POSSIBLY
DEVELOPING LATE SAT NIGHT. ANOTHER ROUND OF SCT SHWRS/TSTMS AND
CIG/VSBY RESTRICTIONS EXPECTED SUN-SUN NIGHT. DRY WEATHER AND VFR
CONDITIONS EXPECTED TO RETURN MON-TUE.
