DISCUSSION
KEY MESSAGE 1: DRY WEATHER WITH SEASONABLE TEMPERATURES EXPECTED
THIS WEEKEND, THEN SLIGHTLY WARMER WITH CONTINUED DRY CONDITIONS
THROUGH LATE NEXT WEEK.
A STRONG NOR'EASTER WILL CONTINUE TO DEVELOP OVER THE MID-ATLANTIC
OFFSHORE WATERS THRU THE WEEKEND, DRIFTING NORTH TOWARD NEW
ENGLAND. THE FORECAST AREA WILL BE ON THE DRY N/NWLY FLOW SIDE
OF THE STORM'S CIRCULATION, WHICH WILL MAKE FOR PLEASANT WEATHER
CONDITIONS ACROSS THE AREA. COOL, CRISP LOW TEMPS WILL CONTINUE
TONIGHT AND AGAIN SATURDAY NIGHT, WHILE HIGHS REBOUND TO NEAR
NORMAL UNDER SUNNY SKIES.
DRY CONDITIONS CONTINUE THRU MOST OF NEXT WEEK, AS AN UPPER
RIDGE SLOWLY BUILDS IN BEHIND THE DEPARTING NOR'EASTER, AND
SFC HIGH PRESSURE REMAINS OVER THE SOUTHEAST. TEMPS WARM TO
SLIGHTLY ABOVE NORMAL, BUT WITH A SLOW, GRADUAL INCREASE IN SFC
DEWPTS/HUMIDITY. WITH NO SIGNIFICANT MOISTURE RETURN UNTIL FRIDAY
AT THE EARLIEST...AND MORE LIKELY OVER THE NEXT WEEKEND...THE
FORECAST REMAINS DRY THRU WEDNESDAY. THE NATIONAL BLEND OF MODELS
SHOWS SLIGHT CHANCE TO LOW- END CHANCE POPS START TO RETURN THURSDAY
THRU FRIDAY, MAINLY IN THE MOUNTAINS.
AVIATION /06Z SATURDAY THROUGH WEDNESDAY/
AT KCLT AND ELSEWHERE: EXPECT DRY, VFR CONDITIONS TO CONTINUE
THRU THE 06Z TAF PERIOD. THE ONLY EXCEPTION COULD BE SOME PATCHY
MTN VALLEY FOG AND/OR LOW STRATUS OVERNIGHT THAT MAY REACH KAVL.
CONFIDENCE REMAINS FAIRLY LOW THAT RESTRICTIONS WILL REACH KAVL,
BUT NONETHELESS, I KEPT A TEMPO FOR 5SM AND BKN004 FROM 09 TO 13Z.
OTHERWISE, SKIES SHOULD REMAIN MOSTLY CLEAR THRU THE TAF PERIOD
WITH WINDS FAVORING A N TO NW DIRECTION THRU THE PERIOD. WINDS
WILL BE LIGHTER OVERNIGHT AND INTO THE MORNING, AND PICK UP IN
THE 5 TO 8 KT RANGE THIS AFTERNOON. 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.
