A WEAK FRONTAL BOUNDARY WILL CONTINUE TO PUSH SOUTHEAST OF THE WESTERN CAROLINAS AND NORTHEAST GEORGIA THIS EVENING. WEAK HIGH PRESSURE WILL THEN PASS BY NORTH OF THE REGION THIS WEEKEND. WARM SOUTHERLY FLOW AROUND HIGH PRESSURE OVER THE ATLANTIC WILL CONTINUE INTO THE MIDDLE OF NEXT WEEK. && .NEAR TERM /THROUGH SATURDAY/... SCATTERED THUNDERSTORMS WILL CONTINUE TO DEVELOP THIS AFTERNOON IN MODERATELY TO STRONGLY UNSTABLE AIRMASS OVER SW NC...NORTHEAST GA... NW CORNER OF SC...IN ASSOCIATION WITH SURFACE TROUGH/WEAK FRONTAL BOUNDARY. COVERAGE HAS TENDED TO DIMINISH AS THE STORMS DROP OFF THE HIGHER TERRAIN...SO WE WILL CONTINUE TO LIMIT POPS TO SLIGHT CHANCE OVER THE PIEDMONT AREAS OF THE UPPER SAVANNAH RIVER VALLEY. OTHERWISE...THE CU FIELD IS LOOKING PRETTY HEALTHY ACROSS OUR EASTERN PIEDMONT ZONES...SO WILL CONTINUE TO ADVERTISE SLIGHT CHANCES IN THOSE AREAS. IN CONSIDERATION OF THE DRYING AIRMASS...WESTERLY FLOW...AND RISING HEIGHTS...CONVECTION SHOULD DIMINISH QUICKLY THIS EVENING. WITH A REASONABLY DRY AIRMASS IN PLACE...MIN TEMPS SHOULD DROP FAIRLY CLOSE TO CLIMO BY SATURDAY MORNING. W/NW FLOW WILL MAINTAIN HOT BUT RELATIVELY DRY CONDITIONS ON SATURDAY. IN FACT...MODEL GUIDANCE DEPICTS LITTLE IN THE WAY OF INSTABILITY TOMORROW AFTERNOON...WITH THE EXCEPTION OF THE UPPER SAVANNAH RIVER VALLEY AND SW MTNS. IN OTHER WORDS...THE SAME AREAS SEEING CONVECTION THIS AFTERNOON ARE THE MOST LIKELY TO SEE IT AGAIN ON SATURDAY. SLIGHT TO LOW CHANCE POPS WILL BE CARRIED IN THESE LOCATIONS BY LATE AFTERNOON. && .SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY/... AS OF 230 PM FRIDAY...WEAK UPPER FORCING MOVES E OF THE AREA SAT EVE AND ANY CONVECTION THAT HAS DEVELOPED WILL DIE OFF WITH COOLING. HEIGHTS RISE SUN AND TEMPS WILL WARM 4-6 DEG ABOVE AVG IN THE AFTN. NOT MUCH UPPER FORCING BUT WEAK SFC BOUNDARY JUST TO THE S WILL TRACK N OVER THE AREA. EXPECT CHC POPS OVER THE MTNS WITH SLIGHT CHC ELSEWHERE...WITH CHC SPREADING ACROSS THE CWA SUN-SUN NIGHT AS THE BOUNDARY MOVES N AND AN H5 SHORTWAVE MOVES IN FROM THE W. ALTHOUGH BOUNDARY MOVES WELL N MON ANOTHER UPPER SHORTWAVE IS EXPECTED TO MOVE IN WHILE AREA REMAINS IN MOIST S FLOW AT THE SFC SO CHC POPS CONTINUE THRU MON AFTN. EXPECT MORE CLOUD COVER MON BUT HIGHS WILL STILL BE ABOVE AVG. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... AS OF 230 PM FRIDAY...MED RANGE MODELS HAVE CHANGED IN THE LAST 24 HOURS BUT REMAIN IN DECENT AGREEMENT KEEPING A WEAK UPPER RIDGE AXIS TO THE W WITH A TROF TO THE E...AND WEAK SHORTWAVES MOVG OVER THE AREA IN THE NW FLOW ALOFT. WARM...MOIST AIR WILL REMAIN OVER THE AREA THUE-WED WITH DIURNALLY ENHANCED SHWRS/TSTMS AND ABOVE AVG TEMPS. THE MODEL CHANGE IS IN PUSHING A WEAK SFC BOUNDARY S...AHEAD OF HI PRES BUILDING OVER THE OH VALLEY WED...THEN EITHER INTO OR S OF THE CWA THU. ECMWF PUSHES IT THRU...THE GFS STALLS IT OVER THE AREA. WITH THE UNCERTAINTY HELD ON TO LOW CHC POP ALONG THE ESCARPMENT INTO THE MTNS THU AFTN DUE TO WEAK SE UPSLOPE ENHANCEMENT DEVELOPING...WITH SLIGHT CHC ELSEWHERE. FRONT EITHER WASHES OUT OR MOVES N OF THE CWA FRI AND WITH MOIST S FLOW OVER THE AREA HAVE SLIGHT CHC POPS FRI AFTN. TEMPS WILL BE ABOUT TWO CATEGORIES ABOVE AVG TUE-WED...THEN ONE CAT ABOVE THU-FRI. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... AT KCLT AND KHKY...SCT CU DEVELOPING IS DEVELOPING OVER THE AREA IN A MODERATELY UNSTABLE AIRMASS. CONVECTION WILL LIKELY DEVELOP OVER THE REGION THIS AFTERNOON...BUT EXPECT COVERAGE TO REMAIN ISOLATED ENOUGH TO PRECLUDE INCLUSION OF CB CLOUD GROUP. OTHERWISE...W/SW WINDS HAVE NOT BEEN QUITE AS STRONG AS PREVIOUSLY ANTICIPATED...SO HAVE SCALED THE FORECAST BACK JUST A BIT THIS AFTERNOON...TO AROUND 12 KT SUSTAINED WITH GUSTS CLOSE TO 20 KT POSSIBLE. OTHERWISE...VFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD. ELSEWHERE...ISOLATED TO WIDELY SCATTERED CONVECTION IS DEVELOPING OVER THE MTNS EARLY THIS AFTERNOON...WITHIN MODERATELY UNSTABLE AIRMASS AND ASSOCIATED WITH BROAD SURFACE TROUGH. CONSIDERING THE MOVEMENT OF THESE STORMS...EXPECT THEM TO REMAINS WEST OF KAVL/KGMU/ KGSP...ALTHOUGH ADDITIONAL ISOLATED STORMS MAY POP UP LATER THIS AFTERNOON...ESP NEAR KGMU/KGSP.
