DRY WEATHER WILL CONTINUE THROUGH THE WEEKEND AND INTO MUCH OF NEXT
WEEK. HIGH PRESSURE WILL CONTINUE TO BUILD INTO THE AREA FROM THE
WEST...MOVING OFFSHORE EARLY NEXT WEEK. SEASONABLE TEMPERATURES WILL
WARM SEVERAL DEGREES ABOVE NORMAL NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 2 PM FRIDAY...MID/UPPER TROUGH AXIS MOVING TOWARD THE WESTERN
CAROLINAS THIS AFTERNOON WILL MOVE OFF THE COAST TONIGHT. MAINLY
HIGH CLOUDS ASSOCIATED WITH THIS SYSTEM WILL PUSH THROUGH RESULTING
IN MOSTLY CLEAR SKIES DURING THE EARLY MORNING HOURS. RADIATIONAL
COOLING WILL BECOME MORE EFFICIENT OVERNIGHT AS THE HIGH CLOUDS
ABATE. LOWS TONIGHT WILL RANGE FROM THE LOWER TO MID 40S WITH NEAR
40 POSSIBLE ACROSS THE TYPICAL COLD SPOTS IF THE CLOUDS EXIT EARLIER
THAN CURRENTLY FORECAST.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 300 PM FRIDAY...AN UPPER LEVEL SHORTWAVE WILL EXIT THE
COAST SATURDAY MORNING. SUBTROPICAL RIDGING OVER TEXAS WILL
MIGRATE EASTWARD TO FLORIDA BY SUNDAY NIGHT WITH CONTINUED DEEP
DRY NORTHWESTERLY FLOW OVER THE CAROLINAS. CLEAR SKIES ARE EXPECTED
THROUGH THE PERIOD. WITH RELATIVELY WARM THICKNESSES PROGGED ON
THE MODELS WE SHOULD RUN A COUPLE DEGREES ABOVE NORMAL ON HIGH
TEMPERATURES...ESPECIALLY SUNDAY. EXCEPT FOR ADDING A WEAK
SEABREEZE (BACKED WIND DIRECTIONS) ALONG THE COAST SOUTH OF CAPE

PREVIOUS FORECAST WERE EXCEEDINGLY MINOR.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
AS OF 300 PM FRIDAY...FLATTENING MID LEVEL RIDGE WILL BE LOCATED JUST
OFF THE COAST ON MONDAY AS WILL LARGE SURFACE HIGH PRESSURE. BOTH
PROGRESS EVER SO SLIGHTLY EAST HEADING INTO TUESDAY WHILE DEEP
OCCLUDED SYSTEM SLIDES EAST NORTH OF THE GREAT LAKES. A WEAK DIPPING
IN THE SOUTHERN BRANCH OF THE JET WILL START TO SPREAD CYCLONIC MID
LEVEL INTO THE CAROLINAS ON WEDNESDAY WHICH MAY HELP LEAD TO THE
FORMATION OF A WEAK PIEDMONT TROUGH. THIS WILL ALSO GIVE A SLIGHT
SOUTHWARD PUSH TO THE COLD FRONT TRAILING FROM THE AFOREMENTIONED
STORM SYSTEM WELL TO OUR NORTH...WITH THIS BOUNDARY LIKELY COMING
THROUGH THE AREA LATE THURSDAY OR THURSDAY NIGHT. THE UNIMPRESSIVE
MOISTURE FLUX AHEAD OF THIS BOUNDARY DOES NOT BODE WELL FOR MUCH IN
THE WAY OF RAIN CHANCES WITH ITS PASSAGE. THE CURRENT SLIGHT CHANCE
POPS SEEM JUST FINE AND WILL REMAIN AS-IS. DESPITE THE WEAK MOISTURE
THE UPPER SYSTEM MAY BE A BIT STRONGER THAN PREVIOUSLY THOUGHT AS
IMPLIED BY A HIGHER QPF NOW SEEN IN THE GFS. PLENTY OF TIME TO SEE
IF THIS TREND HOLDS AND THERE IS A NEED FOR HIGHER RAIN CHANCES.
TEMPERATURES WILL RUN ABOVE CLIMO WITH MOST DAYS FEATURING MID TO
UPPER 70S FOR HIGHS. COOLER AIR SHOULD BE FILTERING IN BEHIND THE
FRONT FOR HALLOWEEN.
