AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
200 PM EDT WED AUG 9 2000

.DISCUSSION...DIURNAL INSTABILITY AND WEAK LEE SIDE SURFACE TROUGH
WITHOUT UPPER LEVEL SUPPORT REST OF THIS AFTN INTO EVENING AND AGAIN
THURSDAY PROVIDES SLIGHT CHANCE OF TSTMS. OTHERWISE CONTINUED MUGGY
AND HOT WITH LESS CLOUDS THAN NOT.

500 MB TROUGH SHARPENS A BIT LATE THURSDAY NIGHT THROUGH FRIDAY
ALLOWING PREFRONTAL SURFACE TROUGH TO SAG SOUTHWARD INTO AREA.
THINK MOS/FAN HIGHS FOR FRIDAY TOO LOW EXPECTING PRETTY GOOD HEATING
AGAIN AHEAD OF SURFACE FRONT. A LITTLE BIT BETTER CHANCE OF TSTMS
FRIDAY AND ACROSS THE NORTHERN RELATIVE TO THE SOUTHERN CWA.

SURFACE HIGH BEHIND FRONT QUITE WEAK BUT UPPER TROUGH LIKELY
ENOUGH TO FORCE SURFACE FRONT INTO CWA SATURDAY. LIMITED SOLAR
SHELTERING PROCEEDING FRONT...SO NOT LIKELY TO SEE ANOTHER WARM
SEASON HYBRID CAD EVENT AS WAS THE CASE ON 6/20 AND 7/24.
FRONT WILL NOT PROCEED hVERY FAR SOUTH OF NC BUT ENOUGH TO LESSEN
THE HEAT AND HUMIDITY SOME THROUGH THE WEEKEND.

.RAH...NONE.
