AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
240 PM EDT THU JUN 4 1998

VERY BUSY. DID NOT GET THE BEST LOOK AT MDL DATA SINCE THEY WERE LATE
AND SVR WX IN CWA. LOOKS LIKE FNT TO WOBBLE ACROSS CWA THRU PERIOD.
APPEARS TO MOVE INTO SRN CWA DURING SAT. SEVERAL SHORT WAVES MOVE OVER
CWA THRU PERIOD. UPR JET IN FAVORABLE POSITION FOR LIFT. SHOULD BE HIGH
POPS TONIGHT AS STRONG/SVR TSRA CONTINUE ACROSS CWA. MOISTURE REMAINS
HIGH AND WIND FIELD REMAINS STRONG EVEN THOUGH INSTABILITY LESSENS A
LITTLE. WITH FNT SAGGING A LITTLE FARTHER SWD...MAY WANT A LITTLE LOWER
POPS SAT NRN TIER. HIGH CHC POPS ELSEWHERE AND OTHER TIMES.

FAN STILL TOO COOL. COOLING ADVERTISED BY FWC MAY BE TOO MUCH...ESP
SINCE THICKNESSES DO NOT FALL MUCH EVEN ACROSS NC. CLOUDS AND PRECIP
WOULD LOWER TEMPS SOMEWHAT. FWC STILL WAY TO GO.
