AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
959 AM EDT SAT APR 20 1996

RAH/CAE: AT LEAST CHANCE POPS ALL AREAS. TEMPS SHUD BE OK.

DISC: LOW CLOUDS HANGING IN SOME AREAS WHILE QUICKLY ERODING IN OTHERS.
LOTS OF BREAKS IN THE MID/HIGH LEVEL CLOUDS WILL ALLOW GUD WARMING TO
OCCUR WHEN LOW CLOUDS FINALLY DISSIPATE. STRONG LINE OF TRW MOVING
ACROSS E TN ATTM. WILL BE INTERESTING TO SEE IF IT DOES THE USUAL
WEAKENING AS IT INTERACTS WITH THE HIGH MOUNTAINS. EVEN IF IT DOES
WEAKEN IT COULD PROVIDE A GUD BOUNDARY FOR CONVECTION OVER PIEDMONT...
FOOTHILLS AND EVEN UPSTATE. OUR 88D VWP SHOWS GUD SPEED SHEAR BUT
LITTLE DIRECTIONAL SHEAR. ADD TO THIS UPPER 50 AND LOWER 60 DEW POINTS
ACROSS CAROLINAS IT LOOKS LIKE ANOTHER ACTIVE DAY.
