DISCUSSION
KEY MESSAGE 1: DRY THROUGH MUCH OF NEXT WEEK WITH ABOVE NORMAL HIGHS
RETURNING EACH AFTERNOON. BELOW NORMAL LOWS STICK AROUND THIS
WEEKEND BEFORE ABOVE NORMAL LOWS RETURN NEXT WEEK.
CYCLONIC FLOW REMAINS ALOFT THROUGH EARLY NEXT WEEK ACROSS MUCH OF
THE EAST COAST. UPPER RIDGING THEN BUILDS ACROSS THE SOUTHEAST BY
MID-WEEK, LINGERING OVER THE REGION THROUGH THE END OF THE FORECAST
PERIOD. AT THE SURFACE, DRY HIGH PRESSURE DOMINATES THE PATTERN
ACROSS THE SOUTHEAST THROUGH AT LEAST THURSDAY. MOISTURE MAY RETURN
AS EARLY AS FRIDAY, PER THE LATEST RUN OF THE CANADIAN, BUT
CONFIDENCE IS LOW AS BOTH THE THE GFS AND EURO CONTINUE TO SHOW DRY
CONDITIONS LINGERING THROUGH FRIDAY. NBM POPS ARE TRENDING MUCH
LOWER FOR THURSDAY. FOR FRIDAY, NBM STILL DEPICTS CHANCE POPS AREA-
WIDE. THINKING NBM POPS ARE POTENTIALLY OVERDONE ON FRIDAY AS
MOISTURE IS MORE LIKELY TO RETURN BY NEXT WEEKEND. LOWS REMAIN BELOW
NORMAL THROUGH SUNDAY NIGHT BEFORE ABOVE NORMAL LOWS RETURN NEXT
WEEK. ABOVE NORMAL HIGHS RETURN TODAY AND LINGER THROUGH THE REST OF
THE FORECAST PERIOD.
AVIATION /12Z SATURDAY THROUGH WEDNESDAY/
AT KCLT AND ELSEWHERE: EXPECT DRY, VFR CONDITIONS TO CONTINUE
THRU THE 12Z TAF PERIOD. WE'VE SEEN SOME MTN VALLEY FOG AND LOW
STRATUS DEVELOP OVER THE USUAL LOCATIONS OVER THE PAST FEW HRS,
BUT IT'S LOOKING LIKE IT WON'T REACH KAVL THIS MORNING. OTHERWISE,
SKIES SHOULD REMAIN MOSTLY CLEAR THRU THE TAF PERIOD WITH WINDS
FAVORING A N TO NW DIRECTION THRU THE PERIOD. KAVL WILL LIKELY
SEE SOME LOW-END GUSTS THIS AFTERNOON/EVENING.
OUTLOOK: DRY, VFR CONDITIONS SHOULD PERSIST INTO THE MIDDLE OF
NEXT WEEK, HOWEVER MTN VALLEY FOG/LOW STRATUS WILL BE POSSIBLE
EACH MORNING.
