DISCUSSION
KEY MESSAGE 1: WARM TEMPERATURES AND NEAR-CRITICAL RH EXPECTED AGAIN
THIS AFTERNOON. BANS ON OUTDOOR BURNING CONTINUE IN BOTH NORTH
CAROLINA AND SOUTH CAROLINA.
DRY AND QUIET CONDITIONS OBSERVED ACROSS THE WESTERN CAROLINAS AS
WE APPROACH DAWN, WITH DEWPOINT DEPRESSIONS OF 10 TO 15 DEGREES
OVER MUCH OF THE AREA, AND CLEAR SKIES VIRTUALLY EVERYWHERE.
AN UPPER RIDGE AXIS PRESENTLY EXTENDING FROM THE DEEP SOUTH INTO
THE OHIO VALLEY WILL BEGIN TO BREAK DOWN TODAY IN RESPONSE TO
DEEPENING UPPER LOWS OVER NOVA SCOTIA AND SASKATCHEWAN...WHILE AT
THE SURFACE, A BERMUDA HIGH-LIKE CONFIGURATION WILL CONTINUE MORE
OR LESS UNABATED. DESPITE STEADY SSW SURFACE FLOW...DEWPOINTS
WILL STRUGGLE TO RECOVER THROUGH THE DAY, AND ANOTHER AFTERNOON OF
LOW RH IS EXPECTED. NEAR-CRITICAL RHS ARE EXPECTED EAST OF THE
MOUNTAINS, WITH AT LEAST SOME LOCATIONS ALONG I-77 FALLING BELOW
25% RH. HOWEVER, WITH MUCH LIGHTER WINDS EXPECTED TODAY, LAND
MANAGERS HAVE NOT INDICATED ANY NEED FOR A FIRE DANGER STATEMENT.
FOR NC AND SC, BURN BANS REMAIN IN PLACE.
THE 00Z SUITE OF HI-RES GUIDANCE DEPICTS WIDELY SCATTERED SHOWERS
DEVELOPING ACROSS THE NC MOUNTAINS AND PIEDMONT THIS AFTERNOON,
AS A VERY WEAK SHORTWAVE SLIDES OUT OF THE MID-ATLANTIC AND ACROSS
THE CENTRAL CAROLINAS THIS AFTERNOON. SKEPTICAL OF ANY RAIN
MAKING IT TO THE GROUND, GIVEN HOW DRY THE BOUNDARY LAYER IS.
BUT, CAN'T ENTIRELY RULE OUT A ROGUE SHOWER HERE OR THERE THIS
AFTERNOON...ESPECIALLY OVER THE MOUNTAINS.
KEY MESSAGE 2: PATTERN CHANGE THIS WEEKEND AND INTO EARLY NEXT WEEK,
WITH RAIN CHANCES EVERY DAY BUT MONDAY.
A COLD FRONT CROSSES THE AREA LATE SATURDAY THEN MOVES SLOWLY EAST
ON SUNDAY. MOISTURE AN FORCING WILL BE SUFFICIENT FOR LIKELY TO
CATEGORICAL SHOWER CHANCES SATURDAY AFTERNOON AND EVENING. THERE
WILL BE ENOUGH INSTABILITY FOR SCATTERED THUNDERSTORMS AS WELL, BUT
NO SIGNIFICANT SEVERE STORM CHANCE. RAINFALL AMOUNTS WILL AVERAGE A
QUARTER OF AN INCH OUTSIDE OF THE MOUNTAINS, WITH A HALF TO POSSIBLY
AN INCH ACROSS THE MOUNTAINS. VERY WELCOME BUT NOT ENOUGH TO
SIGNIFICANTLY REDUCE DROUGHT CONDITIONS. ISOLATED SHOWERS LINGER ON
SUNDAY IN THE MOIST EASTERLY FLOW BEHIND THE FRONT. HIGHS 5 TO 10
DEGREES ABOVE NORMAL SATURDAY REMAIN ABOVE NORMAL SUNDAY BUT LOOK
WEDGE-LIKE IN THE MOIST EASTERLY FLOW. AFTER A DRY MONDAY, RAIN
CHANCES RETURN WITH A SERIES OF FRONTAL SYSTEMS MOVING ACROSS THE
AREA THROUGH THE END OF THE PERIOD. THE POTENTIAL EXISTS FOR 1 TO 2
INCHES OF RAINFALL THROUGH THIS PERIOD, HOPEFULLY BRINGING SOME
DROUGHT RELIEF. TEMPERATURES NEAR NORMAL MONDAY AND TUESDAY RISE
BACK ABOVE NORMAL WEDNESDAY AND THURSDAY.
AVIATION /09Z FRIDAY THROUGH TUESDAY/
AT KCLT AND ELSEWHERE: PREDOMINANTLY VFR TO CONTINUE FOR THE
12Z TAF PERIOD. CLEAR SKIES WITH LIGHT AND VARIABLE WINDS SHOULD
CONTINUE OVERNIGHT, WITH AN INCREASE IN MID-LEVEL DAYTIME CU TODAY.
WINDS WILL PICK UP OUT OF THE SW BY MID-MORNING...WITH LOW-END
SPORADIC GUSTS POSSIBLE, BUT TOO INFREQUENT TO INCLUDE IN THE TAFS.
ISOLATED SHOWERS POSSIBLE ACROSS THE NC MOUNTAINS TODAY...BUT
AGAIN, COVERAGE IS EXPECTED TO BE MUCH TOO LOW FOR A MENTION IN
THE KAVL TAF. PARTLY CLOUDY SKIES CONTINUE INTO TONIGHT, AND MVFR
TO ISOLATED IFR FLIGHT RESTRICTIONS MAY DEVELOP BY DAWN SATURDAY
AS RAIN CHANCES INCREASE AHEAD OF AN APPROACHING COLD FRONT.
SHOWERS WILL CONTINUE INTO SATURDAY.
OUTLOOK: RAIN CHANCES WILL TAPER OFF ON SATURDAY NIGHT. GENERALLY
DRY, VFR CONDITIONS ARE EXPECTED TO RETURN FOR SUNDAY AND MONDAY.
GSP WATCHES/WARNINGS/ADVISORIES
GA...NONE.
NC...NONE.
SC...NONE.
