AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
330 PM EDT MON JUN 3 2002

TROF OVER THE WESTERN U.S. IS HELPING TO BUILD AND STRENGTHEN THE
UPPER RIDGE OVER THE SOUTHEAST.  THE ETA MODELS KEEPS THE 500-700MB
HIGH CENTERED OVER THE CWA THROUGH LATE WEDNESDAY...GIVING US QUITE
A BIT OF HAZE.  THIS RIDGE SHOULD MEAN FAIR WEATHER FOR THE NEXT FEW
DAYS AS ONSHORE WINDS RETURN AND HELPS TO COOL THINGS DOWN JUST A
BIT.  THE SURFACE HIGH TO THE NORTH WILL SHIFT EAST OVER THE
ATLANTIC ON TUESDAY AND WEDNESDAY...KEEPING US WITH EAST AND
SOUTHEAST WINDS.  THE AVN IS A LITTLE FASTER IN MOVING THE RIDGE TO
THE EAST OFF THE COAST.

ON WATER VAPOR LOOPS...THE UPPER LOW OVER THE GULF HAS STARTED TO
MOVE NORTHEAST...BUT SHOULD NOT AFFECT OUR AREA SIGNIFICANTLY IF THE
RIDGE HOLDS ITS GROUND.  RH TIME SECTIONS OVER THE AREA HAVE NOT
BEEN REPRESENTATIVE OF CURRENT CLOUD COVER AS SUBSIDENCE FROM THE
RIDGE HAS HELP TO KEEP CLOUD COVER TO A MINIMUM.

LATEST AVN LOOKS VERY MESSY WITH ENERGY CUTTING OFF OVER THE
SOUTHEAST STATES AND NOT ALLOWING A COOL FRONT TO PASS THROUGH BY
LATE WEEK.  THIS IS DIFFERENT THAN LAST NIGHTS MRF WHICH CUTS OFF
THE ENERGY OVER TEXAS AND ALLOWS A GOOD S/W TROF TO MOVE NORTH OF
THE AREA AND BUILDS A SFC HIGH PRESSURE AREA DOWN OVER THE CWA THIS
WEEKEND.  PREFER THE FRONTAL PASSAGE...BUT WILL NOT BE AS AGGRESSIVE
ON LOWERING TEMPS.  WILL CARRY SLIGHT POPS THROUGH THE EXTENDED DUE
TO THE UNCERTAINTY OF THE PATTERN.

MARINE...WEAK ONSHORE FLOW WILL CONTINUE FOR THE NEXT SEVERAL DAYS
WITH NO FLAGS EXPECTED.
