KEY MESSAGE 1: DRY THROUGH MID-WEEK BEFORE DAILY SHOWER AND
THUNDERSTORM CHANCES RETURN IN ASSOCIATION WITH A COLD FRONT
STARTING FRIDAY. ABOVE NORMAL TEMPERATURES RETURN FOR THE REST OF
THE WEEK.
IT APPEARS SUMMER IS NOT QUIET DONE WITH US YET. ANOTHER LARGE UPPER
ANTICYCLONE DOMINATES THE PATTERN THROUGH THURSDAY ALLOWING FOR
MOSTLY DRY CONDITIONS. HIGHS WILL EXHIBIT A WARMING TREND THROUGH
FRIDAY BUT MORE HUMID CONDITIONS SHOULD HOLD OFF UNTIL THURSDAY.
DESPITE A COLD FRONT TRACKING ACROSS THE FORECAST AREA ON FRIDAY,
THE HEAT AND HUMIDITY WILL STICK AROUND THROUGH EARLY NEXT WEEK AS
NO REAL AIRMASS CHANGE IS EXPECTED. TEMPERATURES WILL REMAIN ABOVE
NORMAL THROUGH THE PERIOD. HEAT INDEX VALUES SHOULD REMAIN BELOW
HEAT ADVISORY CRITERIA EACH AFTERNOON, ESPECIALLY WITH DAILY CHANCES
FOR CONVECTION AHEAD OF AND ALONG THE COLD FRONT ON FRIDAY AND AS
THE FRONT STALLS JUST SOUTH OF THE WESTERN CAROLINAS THIS WEEKEND.
SHOWER AND THUNDERSTORM CHANCES SHOULD RETURN AGAIN MONDAY, MAINLY
ACROSS THE MOUNTAINS.
AVIATION /06Z TUESDAY THROUGH SATURDAY/
AT KCLT AND ELSEWHERE: DRY THROUGH THE 06Z TAF PERIOD. EAST OF
THE MOUNTAINS VFR WILL PREVAIL WITH MAINLY E/ENE WINDS. KAVL MAY SEE
MOUNTAIN VALLEY FOG AND LOW STRATUS DEVELOP OVERNIGHT BUT CONFIDENCE
IS LOW SO WENT WITH A TEMPO FOR ONLY MVFR RESTRICTIONS. WINDS AT
KAVL SHOULD REMAIN CALM THROUGH DAYBREAK BEFORE PICKING UP OUT OF
THE SE BY MID-MORNING. WINDS SHOULD GO CALM AGAIN AT KAVL THIS
EVENING INTO TONIGHT. A FEW TERMINALS EAST OF THE MOUNTAINS SHOULD
ALSO SEE WINDS GO CALM THIS EVENING INTO TONIGHT.
OUTLOOK: DRY AND VFR THROUGH THURSDAY OUTSIDE OF MORNING MOUNTAIN
VALLEY FOG AND LOW STRATUS EACH DAY. A COLD FRONT SHOULD BRING BACK
DAILY SHOWER AND THUNDERSTORM CHANCES (AND POSSIBLE RESTRICTIONS)
