AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
320 PM EDT MON JUN 16 2003

SURFACE FRONT HAS PUSHED INTO THE NORTHEAST CORNER OF THE FORECAST
AREA THIS AFTERNOON. LOW CLOUDS HAVE BEEN VERY SLOW TO ERODE IN THE
NC PIEDMONT TODAY...KEEPING THE AREA MORE STABLE THAN SC/GA AND THE
WRN MOUNTAINS. CONVECTION HAS DEVELOPED IN THE MORE UNSTABLE AREAS
AND THIS SHOULD STEADILY SPREAD EASTWARD ACROSS THE AREA THIS
EVENING...WITH THE STALLING SFC BOUNDARY REMAINING A FOCUS FOR
CONVECTION OVERNIGHT. PER COORDINATION WITH ADJACENT OFFICES...WILL
MAINTAIN THE EXISTING FLOOD WATCH FOR MUCH OF NORTH CAROLINA
TONIGHT. WILL LEAVE IT TO THE MID SHIFT TO ASSESS THE NEED FOR
EXTENSION INTO TUESDAY. ISOLATED FLOODING PROBLEMS COULD DEVELOP
OUTSIDE THE WATCH AREA FARTHER SW...BUT DEGREE OF TRAINING AWAY FROM
THE SURFACE BOUNDARY WILL BE VERY HARD TO ASSESS AND IS PROBABLY NOT
WORTH A WATCH AT PRESENT.

SFC BOUNDARY IS FORECAST TO REMAIN OVER THE NE THIRD OF THE FORECAST
AREA THROUGH TOMORROW WITH THE MODELS IN GOOD AGREEMENT THAT THE
BOUNDARY SLOWLY LIFTS BACK NORTH THROUGH WEDNESDAY. WILL GENERALLY
GO SLIGHTLY LOWER THAN GUIDANCE ON MAXES AND KEEP A SMALL DIURNAL
TEMP RANGE. DEEPER MOISTURE SHOWS UP IN TIME HEIGHTS AGAIN WED WITH
DEEP SW FLOW BUT LESS TRIGGERING AROUND. WILL OPT FOR SOLID CHC POPS
WED AFTN.

STRONG COLD FRONT APPROACHES FROM THE NORTHWEST ON THU WITH HIGHEST
EXTENDED RANGE POPS FEATURED FOR THU NIGHT. MODEL DISCREPANCIES THEN
BEGIN TO SHOW UP. THE GFS HAS BEEN FAIRLY CONSISTENT THE PAST THREE
RUNS WITH HANGING UP THE FRONT ACROSS THE SRN EDGE OF AREA WITH
RETURN FLOW MOISTURE BY SAT. GFS ALSO FEATURES TROUGH AXIS TO THE
WEST OVER THE MS VALLEY. WILL LEAN TOWARD ECM SOLUTION OF PLAINS
RIDGING AND MUCH LATER RETURN OF A WEAKER FRONT FOR LATE WEEKEND AND
RETURN TO DIURNAL AFTN CONVECTION.
