SYNOPSIS
HIGH PRESSURE WILL BUILD INTO THE AREA THROUGH MIDWEEK. AN AREA
OF WEAK LOW PRESSURE AND/OR INVERTED TROUGH WILL MOVE ALONG THE
SOUTHEAST COAST LATE THIS WEEK AND INTO THE WEEKEND.
NEAR TERM /THROUGH TODAY/
AS OF 0230 MONDAY...FAIRLY EXTENSIVE MID/HIGH CLOUD COVER
ADVECTING INTO THE AREA WILL LIMIT HOW COOL WE GET TONIGHT, BUT
LIGHT NERLY CAA CONTINUES. SOME MOISTURE ALOFT CAUGHT IN A WEAK
SHORTWAVE OVERRUNNING THE WEDGE OF COOL AIR HAS LED TO SOME
LIGHT RETURNS ON RADAR, BUT CHANCES OF ANY PRECIP MAKING IT
THROUGH THE CONSIDERABLY DRY AIR BELOW IT AND TO THE GROUND IS
UNLIKELY. WE REMAIN UNDER THE INFLUENCE OF TS DEXTER WELL
OFFSHORE AND HIGH PRES ANCHORED TO THE NORTH, SUPPLYING ENC WITH
NERLY BREEZES AND COOLER/DRIER THAN NORMAL CONDITIONS AND A
PRECIP FREE FORECAST THROUGH THE NEAR TERM. TEMPS WILL MODERATE
A BIT THOUGH TDS WILL REMAIN IN THE LOW TO MID 60S CONTINUING
THE FALL-ESQUE FEEL WE'VE ENJOYED THE LAST FEW DAYS. DIURNAL
STRATO CU WILL FORM ONCE AGAIN, BUT PERHAPS NOT AS DENSE OF
COVERAGE AS WAS SEEN SUNDAY, HENCE THE SLIGHTLY WARMER MAXTS;
LOW TO MID 80S MOST, ~80 OBX.
SHORT TERM /TONIGHT/
AS OF 0245 MONDAY...TROUGH ALOFT W OF THE APPS WITH RIDGING
EXPANDING FROM OVER THE ATLANTIC LEADS TO MORE MERIDIONAL FLOW
ALOFT BUT THE JET WILL REMAIN N OF THE FA. AT THE SFC, COOL HIGH
PRESSURE REMAINS OVER THE AREA WITH DRY AIR CONTINUING TO FILTER
IN FROM THE N THROUGH THE BOTTOM HALF OF THE COLUMN, KEEPING ANY
PRECIP CHANCES UNMENTIONABLE. MID AND UPPER LEVEL CLOUD
COVERAGE FORECAST TO PERSIST AS DEBRIS CLOUDS FROM CONVECTION
ASSOCIATED WITH THE STALLED FRONT WELL TO THE SW ADVECTS OVER
THE AREA, AGAIN DAMPENING COOLING POTENTIAL. MINTS SLIGHTLY
WARMER, MID 60S COASTAL PLAIN, UPPER 60S-LOW 70S INNER BANKS,
MID-UPPER 70S OBX.
LONG TERM /TUESDAY THROUGH SUNDAY/
AS OF 3 AM MONDAY...
KEY MESSAGES
- BELOW NORMAL CONDITIONS CONTINUE INTO THIS WEEKEND
- WET CONDITIONS RETURN THURSDAY THROUGH AT LEAST SATURDAY
DRY HIGH PRESSURE WILL HANG ON TUESDAY AND WEDNESDAY WITH COOL
NE FLOW PERSISTING. HIGHS WILL BE IN THE LOW TO MID 80S TUESDAY,
AND THEN MID TO UPPER 80S WEDNESDAY, BUT WITH DEWPOINTS STILL
IN THE 60S, IT WILL STILL FEEL PLEASANT WITH "LOW" HUMIDITY. WE
SHOULD REMAIN MOSTLY DRY TUESDAY ASIDE FROM A FEW PASSING
SHOWERS ALONG THE SOUTHERN NC COAST, AND PERHAPS AS FAR INLAND
AS DUPLIN AND ONSLOW COUNTIES. BETTER MOISTURE ARRIVING FOR
WEDNESDAY WILL YIELD AROUND A 20-30% CHANCE OF RAIN IN THE
AFTERNOON, MOSTLY DRIVEN BY SEA/SOUND BREEZES.
WE'LL ENTER A MORE UNSETTLED PERIOD THURSDAY AS TROPICAL
MOISTURE INCREASES ALONG THE COAST AND AN INVERTED TROUGH AND/OR
WEAK LOW PRESSURE FORM. THE BEST CHANCES (55-65%) FOR RAIN AND
THUNDERSTORMS WILL BE EACH AFTERNOON AND EARLY EVENING, BUT WE
CAN EXPECT SCATTERED SHOWERS AND THUNDERSTORMS OVERNIGHT AND
INTO THE MORNINGS THROUGH SATURDAY. TROUGHING MAY BREAK DOWN AS
EARLY AS SUNDAY, BUT THERE WILL STILL BE AT LEAST SCATTERED
CONVECTIVE COVERAGE. TEMPERATURES WILL REMAIN AROUND OR BELOW
NORMAL DUE TO WIDESPREAD CLOUDS AND PERIODS OF RAIN, BUT HIGH
HUMIDITY WILL RETURN.
AVIATION /06Z MONDAY THROUGH FRIDAY/
SHORT TERM /THROUGH MONDAY/...
AS OF 0200 MONDAY...VFR FLIGHT CATS THROUGH THE PERIOD. MID AND
UPPER LEVEL CLOUDS PERSIST OVERNIGHT WITH LOWER CLOUD DECK OVER
OBX. VIRGA POSSIBLE OVER INLAND ROUTES THROUGH THE OVERNIGHT AS
MOISTURE AHEAD OF A WEAK SHORTWAVE ALOFT PASSES THROUGH, BUT
UNLIKELY ANY PRECIP REACHES THE GROUND. NNEERLY WINDS CONTINUE
MONDAY, BUT NOT AS STOUT OR GUSTY THE WEEKEND, CARRYING 15KT
GUSTS THROUGH PEAK HEATING BUT THERE IS A CHANCE GUSTS FALL OUT
EARLIER THAN SUNSET. DIURNAL STRATOCU FIELD EXPECTED AGAIN BUT
WILL REMAIN AT VFR LEVELS.
LONG TERM /TUESDAY THROUGH FRIDAY/...
AS OF 3 AM MON...GENERALLY VFR CONDITIONS ARE EXPECTED TUESDAY
AND WEDNESDAY WITH DRIER HIGH PRESSURE OVER THE REGION. THURSDAY
THROUGH LATE WEEK, INCREASING MOISTURE AND A WEAK COASTAL

WEAKEN TODAY, BECOMING 10-15 KTS BY THIS AFTERNOON, AND THEN
WINDS MAINTAIN THIS STRENGTH TONIGHT. SEAS WILL SLOWLY SUBSIDE
AS WELL TODAY, DROPPING BELOW 6 FT FOR PORTIONS OF THE COASTAL

SEAS PERSISTS THROUGH FRIDAY. THERE IS ALSO POTENTIAL FOR A LOW

THE PRESSURE GRADIENT LOCALLY, AND LEAD TO THE THREAT FOR HIGHER
WINDS AND SEAS.
