AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
223 PM EDT THU MAY 3 2007

.SHORT TERM /TONIGHT THROUGH FRIDAY/...
THE NEAR-TERM FORECAST IS UNFOLDING MORE OR LESS AS PLANNED...AS
CONVECTION SO FAR TODAY HAS BEEN CONFINED TO AREAS OF TERRAIN
FORCING OVER THE MTNS. MEANWHILE...NOT MUCH IS GOING ON ALONG THE
BACKDOOR FRONT...WHICH IS CURRENTLY MAKING ITS WAY TOWARD THE I-85
CORRIDOR IN NC. IN FACT...THE CU FIELD LOOKS QUITE SUPPRESSED
DESPITE AN AREA OF 1000 J/KG MUCAPE WITHIN THE POOLING MOISTURE AXIS
ALONG/JUST AHEAD OF THE FRONT. WE WILL CONTINUE TO ADVERTISE CHANCE
POPS FOR THIS EVENING FROM ROUGHLY I-85 NORTH.

NUMERICAL GUIDANCE POPS GO THROUGH THE ROOF OVERNIGHT...AS HIGH
LEVELS OF DEEP MOISTURE WILL BE IN PLACE ACROSS THE ENTIRE REGION.
HOWEVER...FORCING IS VERY PALTRY. THERE IS A LITTLE BIT OF WEAK
LOW-MID LEVEL UPGLIDE...BUT THE FLOW IS EXTREMELY WEAK...SO THIS
UPGLIDE WILL NOT BE ESPECIALLY STRONG. SO FAR TODAY...GUIDANCE POPS
FROM EARLIER RUNS HAVE VERIFIED MUCH TOO HIGH...AND THINK THIS IS
LIKELY TO BE THE CASE AGAIN TONIGHT. WE HAVE STUCK VERY CLOSE TO OUR
ORIGINAL FORECAST OF LOW-END LIKELY TO CHANCE POPS ACROSS THE AREA
OVERNIGHT...WHICH UNDERCUTS GUIDANCE BY A GOOD 20-30 PERCENT.

COOL WEATHER EXPECTED ON FRIDAY...AS COLD AIR DAMMING/WIDESPREAD LOW
CLOUDS WILL LIMIT DIURNAL HEATING...ESPECIALLY EAST OF THE MTNS. WE
WILL CONTINUE TO ADVERTISE SOLID CHANCE POPS...AGAIN UNDERCUTTING
GUIDANCE SLIGHTLY DUE TO AN ABSENCE OF FORCING.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
A CHANCE OF SHOWERS CONTINUES FRI NIGHT AND SAT WITH SFC BOUNDARY
EXPECTED TO PUSH WELL S OF AREA SAT NIGHT. SFC HIGH PRESSURE
BUILDS OVER REGION FROM THE NE ON SUN AS UPPER RIDGE BUILDS SUN
THROUGH TUE. EXPECT DRY FORECAST FIRST PART OF WEEK WITH TEMPS
WARMING EACH DAY AND REACHING INTO THE LOW 80S BY TUE AFTN.

AN UPPER WAVE AND ASSOCIATED COLD FRONT ARE EXPECTED TO PUSH E
ACROSS THE PLAINS TOWARD THE REGION...BRINGING AN INCREASING
CHANCE OF RAIN...MAINLY TO THE MTNS WED-THU. AS SYSTEM APPROACHES
AND PUTS AREA INTO INCREASING S FLOW...AFTN HIGHS SHOULD WARM INTO
THE MID 80S BY LATE WED.

&&

.AVIATION /18Z-18Z/...
THE MAIN NEAR-TERM CONCERN WILL BE THE POTENTIAL FOR CONVECTION AT
THE TERMINALS THIS AFTERNOON. THE BEST CHANCE APPEARS TO BE AT
KAVL...WHERE RADAR IMAGERY INDICATED TSRA OVER THE HIGHER ELEVATIONS
JUST WEST OF THE TERMINAL AT 18Z. TEMPOS FOR RA W/ 5SM HAVE BEEN
CARRIED THERE. OUTSIDE OF THE MTNS...THERE IS SOME INSTABILITY
AND BACKDOOR COLD FRONT MAY PROVIDE LOW LEVEL FOCUS FOR WIDELY
SCATTERED CONVECTION...BUT WE DO NOT FEEL THE THREAT IS HIGH
ENOUGH FOR EVEN A TEMPO ATTM. ALTHOUGH SCATTERED SHRA WILL LIKELY
BE AROUND OVERNIGHT...THE MAIN CONCERN WILL BE LOWERING
CIGS...WHICH SHOULD LOWER TO IFR AT MOST TERMINALS SHORTLY AFTER
MIDNIGHT. WIND SHOULD REMAIN OUT OF THE NORTHEAST AT AROUND 10 KTS
OR SO FOR MOST OF THE OVERNIGHT PERIOD...HOPEFULLY PRECLUDING FOG
DEVELOPMENT.

&&

.GSP WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
NC...NONE.
SC...NONE.
