DISCUSSION
KEY MESSAGE 1: DRY WITH NEAR TO BELOW NORMAL HIGHS THROUGH WEEKEND
BEFORE ABOVE NORMAL HIGHS RETURN NEXT WEEK. BREEZY NORTHEAST WINDS
WILL DEVELOP EAST OF THE MOUNTAINS OVER THE WEEKEND.
THE BENIGN WEATHER PATTERN CONTINUES THROUGH MUCH OF NEXT WEEK AS
DRY HIGH PRESSURE REMAINS IN CONTROL. A DRY AND MOSTLY CLEAR COLD
AIR DAMMING WEDGE BUILDS OVER THE REGION THIS WEEKEND, ALLOWING FOR
THE RETURN OF NEAR TO JUST BELOW NORMAL HIGH TEMPERATURES AND BREEZY
NE WINDS. WIND GUSTS ARE MAINLY EXPECTED EAST OF THE MOUNTAINS
RANGING FROM 15-25 MPH (WELL BELOW WIND ADVISORY CRITERIA). GUSTS
SHOULD GRADUALLY TAPER OFF LATE SUNDAY EVENING INTO SUNDAY NIGHT.
GREAT RADIATIONAL COOLING CONDITIONS WILL BE IN PLACE OVER THE
WEEKEND ALLOWING FROST TO DEVELOP ACROSS THE NORTH CAROLINA
MOUNTAINS AND THE NORTHERN FOOTHILLS (WHERE WINDS WILL BE LIGHTER).
DO NOT HAVE A MENTION OF FROST IN THE NORTHERN AND CENTRAL NORTH
CAROLINA MOUNTAINS (WITH THE EXCEPTION OF HENDERSON COUNTY) AS THE
GROWING SEASON HAS ALREADY ENDED FOR THESE LOCATIONS. AN UPPER RIDGE
BUILDING OVER THE REGION EARLY NEXT WEEK WILL ALLOW WARMER AND ABOVE
NORMAL HIGHS TO RETURN.
AVIATION /00Z SATURDAY THROUGH WEDNESDAY/
AT KCLT AND ELSEWHERE: A SEASONABLY DRY AIR MASS, REINFORCED BY
A STRENGTHENING INVERTED SURFACE RIDGE/NE FLOW WILL REMAIN OVER
THE TERMINAL FORECAST AREA THROUGH THIS FORECAST PERIOD. SOME
FOG/LOW STRATUS IS LIKELY TO DEVELOP IN THE MOUNTAIN VALLEYS
SATURDAY MORNING, BUT COVERAGE SHOULD AGAIN BE LIMITED...SIMILAR
TO FRIDAY MORNING. OF SLIGHTLY GREATER CONCERN WILL BE THE
POTENTIAL FOR SOME STRATUS TO DEVELOP ACROSS THE AREA AROUND
SUNRISE...ESPECIALLY IN LOCATIONS CLOSER TO THE BLUE RIDGE. THIS
COULD YIELD A BRIEF PERIOD OF CIGS RESTRICTIONS...MOSTLY LIKELY
MVFR. HOWEVER, THIS IS FAR FROM CERTAIN, AND THE STRATUS
MENTION IS LIMITED TO FEW/SCT LAYERS FOR THE TIME BEING.
OTHERWISE, MOSTLY LIGHT NE WINDS OVERNIGHT...INCREASING TO 9-13
KTS AT MOST PIEDMONT SITES BY LATE SAT MORNING.
OUTLOOK: BREEZY NE WINDS LINGER EAST OF THE MOUNTAINS THROUGH
SUNDAY. DRY AND VFR THROUGH THE MIDDLE OF NEXT WEEK OUTSIDE OF
THE POTENTIAL FOR MOUNTAIN VALLEY FOG AND LOW STRATUS EACH MORNING.
GSP WATCHES/WARNINGS/ADVISORIES
GA...NONE.
NC...NONE.
SC...NONE.
