Area forecast discussion, May 26, 2:29 PM EDT, 5 hours 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
229 PM EDT MON MAY 26 1997

RAH: PROB NEED TO INCLUDE AN EVE PERIOD WITH 50 OR 60% POPS. THINK THE
POPS CAN BE DROPPED FOR TUE BUT LOWER TEMPS TO LOWER 70S.

CAE: PRESENT FCST LOOKS OK AS LONG AS MAIN AREA OF TRW STAYS IN NC
OTHERWISE MAY NEED AN EVE PERIOD WITH 50 TO 60% POPS.

12Z MODELS IN FAIRLY GOOD AGREEMENT OF PUSHING THE FNT THROUGH THE AREA
THIS EVENING AND THEN ALL THE WAY INTO FL ON TUE AS THE CANADIAN HI
STRENGTHENS AND MOVES INTO THE NE U.S. TRW HAVE DEVELOPED AHEAD OF THE
FNT ACROSS NC WITH JUST A FEW IN SC. PRESENT MOVEMENT WOULD CONFINE
MOST OF THE ACTIVITY TO SE NC BUT AS THE FNT SAGS SOUTH COULD SEE
FURTHER DEVELOPMENT. PROB BEST TO INCLUDE AND EVE PORTION FOR BOTH NC
AND SC TO ACCOUNT FOR THE TRW AND FROPA. SLIGHTLY HIER POPS FOR SE NC
LOOK OK ATTM. GOOD NE FLOW WILL SET UP BEHIND THE FNT TON AND CONT ON
TUE. NOT MUCH DRYING IS PROGGED TO OCCUR UNTIL TUE EVE SO THE DAYLIGHT
HOURS LOOK TO BE M/CLOUDY BUT DRY. MODELS HAVE BACKED OFF ON BRINGING
THE UPPER LEVEL SYSTEM OVER THE PLAINS TOWARD THE AREA AND NOW TAKE IT
TOWARD THE GREAT LAKES. IF THIS HAPPENS THERE WILL NOT BE ANYTHING TO
PROVIDE LIFT FOR OVERRUNNING RAIN ON TUE AND THINK POPS CAN BE DROPPED.
LOWS AROUND 60 LOOK FOR TON BUT LOWER 70S ON TUE FOR THE ENTIRE REGION.

CWF: WILL HAVE TO CONT THE SCA/S INTO THE EVE AS THE WINDS GO AROUND TO
THE NE BEHIND THE FNT AND INCREASE BACK TO 20 KT. ONLY SUG ATTM ARE FOR
THE NC WATERS...HOLD WINDS AT 20 KT INTO TUE BUT BRING SEAS UP TO 6 FT
FOR TUE. PRESENT FCST FOR SC WATERS LOOKS GOOD.
