AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
148 PM EDT FRI JUL 30 1999

AS EXPECTED CONVECTION ALMOST GONE FROM SWRN WV EARLY THIS AFTN.
HOWEVER...MODELS INDICATE WE WILL STILL BE ON THE ERN SIDE OF THIS
UPPER RIDGE TONIGHT...BEFORE BUILDING OVER THE REGION ON SAT.  THERE
IS ACTUALLY SOME SYNOPTIC SUPPORT FOR CONVECTION TNITE AS WHAT LOOKS
TO BE A WEAK WARM ADVECTION PATTERN TO MOVE ACROSS.  ATTENDING LOW
LVL BOUNDARY ALREADY SHOWS IN THE STLT CU FIELD ACROSS NERN IN AND
SWRN OH (AND NOW APPEARS WHY THE CONVECTION TRAINED AND LASTED SO
LONG OVER SWRN WV THIS MORNING) WHICH SUPPORTS THE MODELS OPINION.
WITH THE AIR REMAINING VERY UNSTABLE WITH HIGH PW'S...IT WONT TAKE
MUCH FOR STUFF TO GET GOING.  THE MOST LIKELY AREA IS IN THE WEST
AND THEN SHIFT EWD OVERNIGHT...BUT CONFIDENCE IN THE CONVECTIVE
SEASON IS QUITE LOW...SO INTENDING TO GO WITH 30 POPS EVERYWHERE
TNITE AND EARLY SAT MORNING.  SHOULD BE HOT AND DRY MOST OF SAT
UNDER BUILDING UPR RIDGE.  WILL DROP HEAT ADVISORY FOR THIS EVENING
ON FCST PCKG AS EVERYONE KNOWS WHAT THE SITUATION IS BY THEN...BUT
WILL INTRODUCE ANOTHER FOR SAT AFTN OVER THE SAME AREA. COLD FRONT
MOVES SEWD FROM THE GREAT LAKES TO CNTRL OH BY 12Z SUN.  THIS FRONT
HAS SOME PUSH AND UPR SUPPORT SO THAT HIER CHC POPS ARE WARRANTED
WITH COOLER TEMPS UNDER MORE CLOUDS. COOLER AND DRIER AIR FOR MON
AND TUE BEFORE WARMUP AND MOISTURE AHEAD OF NEXT FRONT ON
WED.
