AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC
456 AM EDT WED MAY 7 2025
SYNOPSIS
HIGH PRESSURE WILL BUILD INTO THE AREA THROUGH TODAY, WHILE
ANOTHER LOW PRESSURE AND/OR COLD FRONT IMPACTS THE REGION BY
LATE WEEK.
NEAR TERM /THROUGH TODAY/
AS OF 2 AM WEDNESDAY...STRONG RADIATIONAL COOLING EXPECTED
EARLY THIS MORNING WITH MOSTLY CLEAR SKIES EARLY AND LIGHT TO
CALM WINDS. THIS SHOULD ALLOW TEMPS TO FALL INTO THE LOW/MID
50S INLAND AND LOW/MID 60S FOR THE BEACHES.
COLD FRONT THAT HAS BEEN NEAR US THE PAST COUPLE DAYS FINALLY
SHIFTS OFFSHORE THROUGH THE MORNING AS HIGH PRESSURE CONTINUES
BUILDING IN. DRY THROUGH THE DAY, ALTHOUGH HIGH AND MID LEVEL
CLOUDS MOVE IN FROM THE WEST TODAY, BRINGING INCREASINGLY CLOUDY
CONDITIONS WITH WINDS REMAINING LIGHT. SEA BREEZE MOVES THROUGH
TODAY, WITH WINDS BECOMING SOUTHERLY BEHIND IT. HIGHS IN THE LOW
TO MID 80S INLAND, UPPER 70S TO NEAR 80 FOR BEACHES.
SHORT TERM /TONIGHT/
AS OF 215 AM WEDNESDAY...AN AREA OF WEAK ISENTROPIC LIFT MOVES
THROUGH THE REGION TONIGHT, BRINGING SLIGHT CHANCES OF LIGHT
RAIN. DRIER AIR CLOSER TO THE SURFACE WILL ALLOW FOR SOME
EVAPORATIVE COOLING TO OCCUR AS DROPLETS STRUGGLE TO MAKE IT TO
THE GROUND. THIS DRY LAYER PREVENTS ME FROM GOING HIGHER THAN
15% FOR POPS TONIGHT. QPF AMOUNTS ARE EXPECTED TO BE MINIMAL
(UNDER 0.05"), BUT CLOUD COVER WILL HELP KEEP TEMPS MODERATED.
LOWS TONIGHT IN THE LOW 60S INLAND, MID 60S ALONG THE COAST.
LONG TERM /THURSDAY THROUGH TUESDAY/
AS OF 4 AM WEDNESDAY...A NORTHERN STREAM TOUGH DIGGING INTO THE
NORTHERN MID-ATLANTIC WILL PARTIALLY ABSORB A CUT OFF LOW
SLOWLY PUSHING EASTWARD ACROSS THE CENTRAL CONUS LATE IN THE
WEEK. MEANWHILE SFC LOW PRESSURE WILL DEEPEN ACROSS THE PIEDMONT
LATE THRUSDAY AND LIFT NORTH AND OFF THE MID-ATLANTIC COAST
THURSDAY NIGHT WITH A TRAILING SFC COLD FRONT PUSHING ACROSS THE
AREA FRIDAY EVENING. FAVORABLE JET DYNAMICS WILL BRING
SCATTERED SHOWERS AND THUNDERSTORMS WITH HIGHEST PROBS THURSDAY
NIGHT AND FRIDAY.
HIGH PRESSURE RIDGES INTO THE AREA FROM THE NORTH OVER THE
WEEKEND, WHILE ANOTHER UPPER LEVEL CUT OFF LOW DEEPENS ACROSS
SOUTHERN STATES WHICH MAY CONTINUE TO BRING UNSETTLED WEATHER
ACROSS THE AREA WITH OVERRUNNING MOISTURE LIFTING NORTH TOWARD
THE AREA. 07/00Z GUIDANCE REMAINS MIXED WHERE THERE WILL BE DEEP
ENOUGH MOISTURE TO BRING PRECIP ACROSS ENC OR WHETHER IT WILL
REMAIN SOUTH OF THE AREA, BUT DO EXPECT MOSTLY CLOUDY SKIES
THROUGH THE WEEKEND. THE UPPER LOW BEGINS TO LIFT NORTHWARD
EARLY NEXT WEEK WHICH WILL BRING BETTER PRECIP CHANCES ACROSS
THE REGION WITH A GOOD MOISTURE FEED AND UPPER LEVEL DYNAMICS.
AS IS TYPICAL WITH AMPLIFIED PATTERNS AND CUT OFF LOWS, GUIDANCE
STRUGGLES WITH THE EVOLUTION AND TIMING CONTINUING TO BRING BELOW
AVERAGE CONFIDENCE WITH THE FORECAST DETAILS.
AVIATION /08Z WEDNESDAY THROUGH SUNDAY/
SHORT TERM /THROUGH 06Z THURSDAY/...
AS OF 230 AM WEDNESDAY...PATCHY, SHALLOW FOG CHANCES INCREASE
EARLY THIS MORNING. THE BEST CHANCES FOR FOG DEVELOPMENT WILL
BE ALONG AND EAST OF HWY 17 WHERE THERE IS A BIT MORE MOISTURE,
INCLUDING OAJ AND EWN. SHALLOW FOG CLEARS OUT BY 9AM, LEADING TO
INCREASING MID AND HIGH CLOUDS THROUGH THE DAY. WINDS REMAIN
GENERALLY LIGHT AND VARIABLE, BECOMING MORE SOUTHERLY 5-10KT
BEHIND THE SEA BREEZE THIS AFTERNOON/EVENING FOR COASTAL SITES.
LOW LEVEL CLOUDS, MAYBE WITH SOME LIGHT RAIN, MOVE IN TONIGHT,
ALTHOUGH CONDITIONS ARE EXPECTED TO REMAIN VFR AT THIS TIME
GIVEN DRIER NEAR SURFACE CONDITIONS.
LONG TERM /THURSDAY THROUGH SUNDAY/...
AS OF 430 AM WEDNESDAY...AN UPPER TROUGH AND SFC COLD FRONT
WILL BRING INCREASING PRECIP CHANCES LATE THURSDAY INTO FRIDAY
WITH PERIODS OF SUB-VFR CONDITIONS POSSIBLE. MOST MODELS
CONTINUE TO TREND DRIER FOR SATURDAY AND SUNDAY BUT OVERRUNNING
MOISTURE WILL KEEP SKIES MAINLY CLOUDY. HOWEVER, IF PRECIP DOES
LIFT SUFFICIENTLY NORTH, COULD SEE SOME SHOWERS BRINGING SUB-
VFR CONDITIONS.
