AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC
238 PM EST THU NOV 20 2025
SYNOPSIS
HIGH PRESSURE REMAINS OFFSHORE THROUGH TONIGHT. A WARM FRONT
WILL MOVE ACROSS NORTHERN NC TOMORROW FOLLOWED BY A COLD FRONT
PUSHING THROUGH THE AREA LATE SATURDAY. COOLER AND DRIER HIGH
PRESSURE REBUILDS SUNDAY INTO EARLY NEXT WEEK BEFORE ANOTHER
COLD FRONT BRINGS THE NEXT CHANCE OF RAIN TUESDAY AND
WEDNESDAY.
NEAR TERM /THROUGH TONIGHT/
AS OF 2 PM THU...WEAK COLD AIR DAMMING IS DIMINISHING EARLY THIS
AFTERNOON ACROSS ENC. LOW CLOUDS ARE FINALLY CLEARING ACROSS
THE NORTHERN COASTAL PLAIN WHERE TEMPS REMAIN CHILLY AND IN THE
MID 50S. FARTHER SOUTH, SUNSHINE RETURNED LATE THIS MORNING AND
TEMPERATURES HAVE WARMED IN TO THE LOWS 60S, WITH HIGHS IN THE
MID TO UPPER 60S EXPECTED. SKIES SHOULD REMAIN MOSTLY CLEAR INTO
THIS EVENING UNTIL MID AND HIGH LEVEL CLOUDS BEGIN TO STREAM IN
FROM THE WEST IN ADVANCE OF THE NEXT FRONTAL SYSTEM. HOW QUICKLY
AND HOW THICK CLOUD COVER BECOMES TONIGHT WILL BE A DETERMINING
FACTOR AS TO WHETHER OR NOT THERE IS ANY FOG DEVELOPMENT, SINCE
OTHERWISE IDEAL RADIATIONAL COOLING CONDITIONS WILL BE PRESENT
ALONG WITH AMPLE LOW LEVEL MOISTURE. CONFIDENCE IS HIGH ENOUGH
TO INCLUDE SOME PATCHY FOG IN THE FORECAST, BUT THERE IS
POTENTIAL FOR DENSER FOG IF CLOUDS ARE SLOWER/THINNER OVERNIGHT.
LOW TEMPS TONIGHT SHOULD DROP INTO THE LOW TO MID 40S INLAND,
AND LOWER 50S ALONG THE COAST.
SHORT TERM /FRIDAY/
AS OF 2 PM THU...A WARM FRONT WILL SLIDE INTO ENC FROM THE WEST
TOMORROW MORNING, MAKING FOR A COMPLEX FORECAST WITH A LARGE
TEMPERATURE GRADIENT FROM NORTH TO SOUTH. THE FRONT IS EXPECTED
TO REMAIN MOSTLY EAST/WEST ORIENTATED ALONG THE NC/VA BORDER
WITH ISOLATED TO SCATTERED SHOWERS DEVELOPING ALONG IT THROUGH
THE DAY AS FAR SOUTH AS THE US 264 CORRIDOR. FARTHER SOUTH IT
WILL REMAIN MOSTLY DRY WITH SOME BREAKS OF SUN, WHICH WILL LEAD
TO A SUBSTANTIAL TEMPERATURE GRADIENT IN THE AFTERNOON.
DEPENDING ON HOW MUCH SUN IS SEEN, AREAS ALONG AND SOUTH OF US
70 COULD REACH THE MID TO UPPER 70S, WHILE AREAS ALONG AND NORTH
OF US 64 REMAIN IN THE LOWER 60S WITH DREARY CONDITIONS THROUGH
THE DAY. THE MIDDLE GROUND IS THE MOST IN QUESTION, WITH UPPER
60S TO LOW 70S LIKELY, BUT THERE IS BUST POTENTIAL BOTH UP AND
DOWN HERE DEPENDING ON THE EXACT TRACK OF LOW CLOUDS AND RAIN.
LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/
AS OF 2 PM THU...MAINLY MILD CONDITIONS EXPECTED WITH ABOVE
CLIMO TEMPS THROUGH MID NEXT WEEK. CHANCES FOR LIGHT RAIN SAT
THROUGH EARLY SAT NIGHT. ANOTHER SYSTEM BRINGS RAIN CHANCES BY
MID NEXT WEEK.
SAT...ON SAT, ENC IS IN WARM SECTOR WITH HIGHS REBOUNDING BACK
INTO THE 70S AS WARM FRONT WILL HAVE LIFTED NORTH. KEPT POPS IN
THE CHC RANGE FOR NOW SATURDAY AND SATURDAY NIGHT. RAIN AMTS DO
NOT APPEAR IMPRESSIVE, BUT PERHAPS SOME AREAS COULD SEE A
WETTING RAIN. COULD STILL SEE A FEW RUMBLES OF THUNDER IF
SURFACE HEATING IS STRONG ENOUGH AND UTILIZES THE MODEST
INSTABILITY PRESENT.
SUN THROUGH MON...HIGH PRESSURE IS THEN FORECAST TO BUILD IN
BEHIND THE EARLY WEEKEND FRONT, WITH DRY CONDITIONS ENSUING.
ZONAL FLOW WILL BE IN PLACE, SO TEMPS SHOULD BE AROUND AVG
DURING THIS PERIOD, WITH HIGHS IN THE 60S TO NEAR 70 AND LOWS IN
THE 40S. SUN NIGHT WILL BE THE COOLEST NIGHT, WITH LOWS IN THE
30S INTERIOR TO 40S COAST.
TUE THROUGH WED...NEXT CHANCE FOR RAIN ARRIVES BY TUE, AND ESP
TUE NIGHT INTO EARLY WED, AS SHORTWAVE AND FRONTAL BOUNDARY
SWEEP THROUGH. THIS SYSTEM HAS THE POTENTIAL TO TAP INTO SOME
GOM MOISTURE, AS LAYER STREAMLINES ARE OUT OF THE SW THROUGH THE
SE CONUS, BUT TIMING AND MESOSCALE FEATURES ARE YET TO BE IRONED
OUT, SO NO HIGHER THAN 30-50% POPS THIS FAR OUT IN TIME. TEMPS
REBOUND TO WARMER THAN CLIMO, WITH HIGHS IN THE 70S AND LOWS IN
THE 40S TO 50S.
AVIATION /18Z THURSDAY THROUGH TUESDAY/
AS OF 1245 PM THURSDAY...
KEY MESSAGES
- CHANCE OF FOG TONIGHT WITH THE GREATEST POTENTIAL NORTH OF
HIGHWAY 70/I-42
- CHANCES FOR SHOWERS AND SUB-VFR CONDITIONS TOMORROW AS A
WEAK WARM FRONT LIFTS THROUGH THE AREA
LOW STRATUS HAS MIXED OUT ACROSS THE SOUTHERN HALF OF THE
FORECAST AREA AS OF EARLY WEDNESDAY AFTERNOON BUT CONTINUES TO
LINGER NORTH OF HIGHWAY 70. VISIBLE SATELLITE TRENDS INDICATE
THAT THE LINGERING LOW CEILINGS WILL SOON LIFT FOR THE REMAINING
TAF SITES THROUGH 19Z; HOWEVER. VFR CONDITIONS WILL THEN
PERSIST THROUGH THE EARLY OVERNIGHT HOURS WITH CALM WINDS AND
ONLY SOME SCATTERED MID/HIGH CLOUDS.
FORECAST UNCERTAINTY THEN INCREASES AFTER MIDNIGHT TONIGHT.
MOST GUIDANCE IS INDICATING PATCHY TO AREAS OF FOG DEVELOPING
AFTER MIDNIGHT, WITH THE GREATEST POTENTIAL NORTH OF HIGHWAY
70/I-42. THIS WOULD BRING SUB-VFR VIS TO PGV AND ISO. GUIDANCE
REMAINS UNCERTAIN ON WHETHER POTENTIAL WILL EXTEND FARTHER SOUTH
TO EWN/OAJ. ADDITIONALLY, MID-TO-HIGH LEVEL CLOUDS ARE FORECAST
TO BEGIN INCREASING OVERNIGHT AHEAD OF AN APPROACHING WARM
FRONT. SHOULD THESE CLOUDS BUILD IN THICKER AND/OR QUICKER THAN
ANTICIPATED, THE OVERALL POTENTIAL FOR FOG MAY BE TEMPERED.
SHOULD CLOUDS BE SLOWER/THINNER, FOG POTENTIAL WILL BE GREATER
AND MAY BRING IFR TO LIFR VIS. HAVE TRENDED THE TAFS TOWARDS
LOWER VIS THIS CYCLE, BUT GIVEN UNCERTAINTY, HAVE ONLY
INTRODUCED MVFR VIS FOR PGV/ISO.
WARM FRONT IS THEN FORECAST TO BEGIN LIFTING THROUGH THE REGION
TOMORROW MORNING. ANY FOG IS EXPECTED TO MIX OUT AFTER SUNRISE,
BUT WAA ATOP THE FRONTAL INVERSION IS EXPECTED TO LEAD TO
LOWERING CEILINGS AND INCREASING CHANCES FOR SHOWERS THROUGH THE
MORNING AND INTO THE AFTERNOON, INCLUDING ANOTHER CHANCE FOR
SUB-VFR CONDITIONS. GIVEN UNCERTAINTY REGARDING TIMING AND
COVERAGE, HAVE OPTED AGAINST ANY INCLUSION IN THE TAFS AS OF
THIS CYCLE BUT WILL CONTINUE TO MONITOR FOR FUTURE ADJUSTMENTS.
OUTLOOK: YET ANOTHER CHANCE FOR SUB-VFR CONDITIONS OVER THE
WEEKEND WHEN A SERIES OF APPROACHING, AND EVENTUALLY PASSING,
FRONTS INCREASE RAIN CHANCES AND SKY COVER. HIGHEST CHANCES
CURRENTLY SAT EVENING INTO SUN MORNING, ALTHOUGH TYPICAL TIMING
DIFFERENCES LOWER CONFIDENCE.
MARINE

KEY MESSAGES...
- SMALL CRAFT CONDITIONS LIKELY TO DEVELOP FOR PORTIONS OF THE
COASTAL WATERS EARLY SATURDAY MORNING THROUGH SUNDAY.

30 KTS BY EARLY SATURDAY MORNING. STRONG SW WINDS CONTINUE
THROUGH SATURDAY AFTERNOON WHEN A COLD FRONT CROSSES THROUGH THE
MARINE WATERS FROM NORTH TO SOUTH AND WINDS SWITCH TO N 15-25
KTS BEHIND IT THROUGH SATURDAY NIGHT.
SEAS WILL BE 2-4 FT THROUGH SATURDAY MORNING, AND THEN INCREASE
TO 3-5 FT THROUGH SUNDAY WITH SOME PERIODS OF 6 FOOT SEAS
POSSIBLE OVER PORTIONS OF THE WATERS OFF CAPE HATTERAS.
OUTLOOK: IMPROVING CONDITIONS EXPECTED SUNDAY WITH WINDS
BECOMING N 10-20 KTS. LIGHT NORTHERLY FLOW CONTINUES MONDAY WITH
