Area forecast discussion, Jun 13, 3:40 PM EDT, 4 hours 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
340 PM EDT WED JUN 13 2001

SATELLITE IMAGERY...RADAR...AND SURFACE OBSERVATIONS SHOW
SUBTROPICAL LOW IN THE VICINITY OF FLORENCE THIS AFTERNOON...MOVING
SLOWLY OFF TO THE EAST. LATEST MODEL RUNS SHOW THIS COMPACT SYSTEM
TRUDGING OFF TO THE EAST OVERNIGHT TO THE NC COASTAL PLAINS...WHERE
IT GRINDS TO A HALT AS AN UPPER RIDGE BUILDS OVER NY/NEW ENGLAND AND
BLOCKS ITS ESCAPE. THIS SYSTEM HAS A HISTORY OF CRAWLING ALONG SO
THIS SEEMS REASONABLE...THUS THE SLOWER ETA SOLUTION IS FAVORED IN
KEEPING THE LOW IN THE PICTURE THROUGH FRIDAY.

MOST OF THE PRECIP WRAPPING AROUND THE NW SIDE OF THE LOW IS
EXPECTED TO MOVE OUT OF UNION COUNTY NC BY MIDNIGHT OR THEREABOUTS.
IN THE MEAN TIME...THE FLASH FLOOD WATCH FOR UNION COUNTY NC WILL
CONTINUE THROUGH 8 PM AND MAY BE EXTENDED IF ADDITIONAL RAIN BANDS
WRAP IN FROM CENTRAL NC. WILL GO WITH A LIKELY POP IN THAT
ZONE...WITH CHANCE ELSEWHERE TO HANDLE ONGOING CONVECTION.

BY THURSDAY MORNING...THE LOW IS EXPECTED TO BE FAR ENOUGH TO THE
EAST THAT ANY SUBSEQUENT RAIN BANDS THAT DEVELOP WILL REMAIN TO THE
EAST OF THE FORECAST AREA. THE MAIN EFFECT OF THE LOW WILL BE THE
RELATIVELY DEEP MOISTURE THAT SHOULD PERSIST ACROSS THE AREA THROUGH
AT LEAST FRIDAY...WITH SUFFICIENT INSTABILITY FOR DEEP CONVECTION.
THE MAIN QUESTION WILL BE A TRIGGER MECHANISM. UPPER SUPPORT IS NOT
ESPECIALLY FAVORABLE...BUT NEITHER IS IT UNFAVORABLE. THE MAIN
SUPPORT SUGGESTED BY THE ETA WOULD BE LOW LEVEL CONVERGENCE...OF
VARYING DEGREE...THROUGHOUT THE SHORT RANGE PERIOD. THIS SHOULD BE
ENOUGH FOR SCATTERED MAINLY AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS FOR THE NEXT TWO DAYS. TEMPERATURES SHOULD BE
SUMMERLIKE AS WELL.

LOOKING BRIEFLY AT THE EXTENDED...AVN MOVES SURFACE FRONT ACROSS THE
AREA EARLY SATURDAY. EXPECT THIS IS TOO FAST GIVEN THE STALLING LOW
OVER EASTERN NC OVER THE NEXT FEW DAYS. WILL CONTINUE WITH THE
PREVIOUS IDEA OF FRONTAL PASSAGE LATER SATURDAY WITH A CHANCE OF
SHOWERS AND THUNDERSTORMS. WILL KEEP A DRY FORECAST THEREAFTER.
