AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON, NC
200 PM EDT WED JUN 27 2001

ISOLATED SHOWERS/THUNDERSTORMS TODAY...VERY SMALL IN SIZE/SHORT
LIVED AND CONFINED TO THE SEA BREEZE. WILL KEEP A SMALL POP INTO
TONIGHT AREA WIDE AS THERE IS ANOTHER WEAK SHORT WAVE MOVING NORTH
ACROSS EAST PORTIONS OF SOUTH CAROLINA.

HIGH PRESSURE AND WEAK SUBSIDENCE TOMORROW ALONG WITH SLIGHTLY
WARMER AND DRIER AIR ALOFT SHOULD YIELD EVEN LESS COVERAGE AND
EXPECT THIS TREND TO CONTINUE. LOW LEVEL MOISTURE STILL PLENTIFUL
AND WITH S TO SE FETCH CONTINUING...DO NOT EXPECT THIS TO CHANCE.
BUT FOR NOW WILL KEEP POPS BELOW THRESHOLD.

HIGH PRESSURE RIDGE SHIFTS GRADUALLY SOUTH OF THE REGION AND THIS
ALLOWS COLD FRONT TO SLIP SOUTH FROM MID ATLANTIC AS HIGH MOVES
ACROSS ONTARIO AND INTO NORTHEAST. FRONT IS GOING TO HAVE A TOUGH
TIME MAKING SOUTHWARD PROGRESS AS IT BUCKS THE RIDGE AND FLOW
PARRALLES THE BOUNDARY. WILL KEEP POPS IN SLIGHT CHANCE TO CHANCE
SUNDAY THROUGH WEDNESDAY.

CWF:  S TO SE WIND LESS THAN 10 KT AND SEAS 2 FT. LITTLE CHANCE OVER
THE NEXT FEW DAYS.
