AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
204 PM EDT WED MAY 24 2000

SHORT TERM CONCERN IS FOR DEVELOPMENT OF CONVECTION IN RESPONSE TO
SMALL SHORTWAVE ENTERING CWA ATTM AND ITS INTERACTION WITH HIGH SFC
DWPTS AND DIFFERENTIAL HEATING BOUNDARIES. S/W ALSO TRACKING ESE IN
MAX THETA-E RIDGE AND SFC LIS ARE -5 TO -6 ACCORDING TO MSAS. WILL
WAIT TO LAST POSSIBLE MINUTE TO DETERMINE POPS FOR THIS
EVENING/TONIGHT BASED ON UPSTREAM DEVELOPMENTS.

LATEST ETA RUN NOT AS UNSTABLE/MOIST AS PREVIOUS. SFC COLD FRONT TO
SLIDE SOUTH THROUGH THE CWA EARLY THURSDAY. AS UPR FLOW BECOMES MORE
UNIDIRECTIONAL OUT OF THE WEST...BOUNDARY STALLS IN OR JUST TO THE
SOUTH OF CWA. THEN UPR RIDGE STARTS TO AMPLIFY AGAIN FRIDAY AHEAD OF
SYSTEM COMING THROUGH THE CENTRAL PLAINS...AND BOUNDARY LIFTS NORTH
AS A WARM FRONT FRIDAY. NO REAL MID-LEVEL FORCING AGAIN UNTIL LATER
THURSDAY INTO FRIDAY...AND EVEN THAT IS WEAK AND SHEARED. WE WILL
HAVE BOUNDARY/THETA-E RIDGE/THICKNESS DIFFLUENCE AND MOIST AIR MASS
OVER US FOR MUCH OF THE NEXT 48 HOURS. SO THE INGREDIENTS ARE THERE
FOR SHOWERS AND THUNDERSTORMS. SEEMS REASONABLE THAT MCS AFTER MCS
OR THE REMAINS OF SUCH WILL CONTINUE TO TAKE AIM AT OUR CWA...BUT
WITHOUT ANY ADDITIONAL GUIDANCE HELPING TO RESOLVE THE TEMPORAL AND
SPATIAL RESULTS OF THE MCSS...WILL BE HARD AT THIS POINT TO GO
HIGHER THAN CHC POPS THROUGH THE PERIOD. MAY EVEN LEAVE THUNDER OUT
OF NORTHERN ZONES ON THURSDAY...SINCE THAT AREA TO BE MOST STABLE.

WITH EXPECTED CLOUD COVER IN VICINITY OF BOUNDARY...WILL GO SLIGTHLY
LOWER THAN GUIDANCE FOR HIGH TEMPS THURSDAY. IN THE EXTENDED...LOOKS
LIKE WILL NEED TO KEEP CHC SHRA/TSRA FRIDAY NIGHT...THEN AGAIN
SUNDAY WITH PASSAGE OF FRONT. MONDAY SHOULD BE DRIER AND COOLER.
