AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
205 PM EDT THU MAY 25 2000

BIGGEST CONCERN IS FOR THE FIRST PERIOD. SEVERE TSTM WATCH JUST
ISSUED FOR MUCH OF WRN HALF OF CWA. ISOLATED STORMS DEVELOPING ALONG
SFC TROUGH/OUTFLOW BOUNDARY ACROSS N GA. EXPECT TO SEE RAPID
DEVELOPMENT INTO OUR AREA THIS AFTERNOON WITH THE VERY JUICY AIRMASS
IN PLACE. STABLE AIRMASS TO SINK SOUTH TONIGHT...DEPICTED BY
ADVECTION OF LOWER THETA-E AND HIGHER LIFTED INDICES. ALTHOUGH SOME
SHRA/TSTMS COULD MAKE IT ACROSS NRN TIER THIS EVENING...MOST
WIDESPREAD CONVECTION AND SEVERE WX SHOULD BE LIMITED TO SRN TIER OF
NC...SOUTH. SO AM THINKING OF GOING WITH 40 POP NORTH TO POSSIBLY AS
HIGH AS CATEGORICAL SOUTH...DEPENDING ON TRENDS TOWARD ISSUANCE.

FRONT STALLS TO THE SOUTH OVERNIGHT...THEN AS UPR RIDGE BUILDS OVER
THE SOUTHEAST...SFC BOUNDARY LIFTS BACK NORTH DURING THE DAY FRIDAY.
NO REAL SYNOPTIC SCALE TRIGGERS TO SET CONVECTION OFF TOMORROW...BUT
WITH ADVECTION OF HIGHER THETA-E BACK ACROSS THE BOUNDARY AS IT
BECOMES ORIENTED NORTHWEST TO SOUTHEAST THROUGH THE MIDDLE OF CWA BY
FRIDAY AFTN...WILL GO WITH A CHC OF SHRA/TSTMS FOR THE WRN HALF. THERE
MAY ALSO BE SOME PRECIP FROM ANY OVERNIGHT MCS ACROSS THE SRN PART
OF CWA. AIR TOO STABLE FARTHER NORTHEAST TO WARRANT A MENTION OF
SHOWERS. WILL CONTINUE CHC OF TSRA INTO FRIDAY EVENING FOR THE ABOVE
MENTIONED AREAS.

SATURDAY LOOKS VERY WARM WITH 850 TEMPS EXCEEDING 20 C ACROSS THE
FOOTHILLS/PIEDMONT. ATMOSPHERE PROBABLY TOO DRY ACROSS ALL BUT THE
MTNS TO PRODUCE CONVECTION...BUT WILL GO WITH THE USUAL SUMMERTIME
AFTN/EVE CHC OF TSRA IN THE MTNS OF NC.

NECT COLD FRONT CRUISES THROUGH EARLY SUNDAY...WITH CONVECTION
POSSIBLE AHEAD OF IT SATURDAY NIGHT. CUT-OFF LOW SINKING OVER AREA
MONDAY MAY PROVIDE ENOUGH INSTABILITY TO GENERATE SHRA/TSTMS...BUT
WE WILL SEE.
