AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC
751 PM EDT THU AUG 7 2025
SYNOPSIS
AN AREA OF WEAK LOW PRESSURE WILL MOVE ALONG THE SOUTHEAST
COAST LATE THIS WEEK AND INTO THIS WEEKEND, WHICH WILL BRING
MULTIPLE ROUNDS OF MODERATE TO HEAVY RAINFALL TO ENC.
NEAR TERM /TONIGHT/
AS OF 2:30 PM THURSDAY...ENC REMAINS SANDWICHED BETWEEN
PERSISTENT MID-LEVEL RIDGING OVER THE WESTERN ATLANTIC A WEAK
MID-LEVEL LOW NEAR THE WESTERN NC/SC BORDER. AT THE SURFACE, THE
CAD WEDGE IS HOLDING STEADY TO OUR WEST WHILE A LOW LINGERS
OFFSHORE WITH INVERTED TROUGHING EXTENDING INTO THE AREA. THIS
SETUP IS SUPPORTING CLOUDY SKIES, GUSTY NORTHEASTERLY WINDS, AND
SCATTERED SHOWERS. TEMPS ARE NOT EXPECTED TO EXCEED THE
UPPER-70S TO LOW-80S.
A CONTINUOUS CORRIDOR OF MOISTURE IS STREAMING ALONG THE
SOUTHEASTERN COAST AND BEING LIFTED ALONG A STALLED FRONTAL
BOUNDARY OFFSHORE, WHICH IS CONTINUING TO SUPPORT SCATTERED
SHOWERS ACROSS THE AREA. ALTHOUGH INSTABILITY ISN'T IN GREAT
SUPPLY, A FEW RUMBLES OF THUNDER CAN'T BE RULED OUT. RAIN RATES
AREN'T EXPECTED TO BE AS HEAVY AS YESTERDAY, BUT SOME MODERATE
TO HEAVY RAINFALL IS STILL POSSIBLE, ESPECIALLY DURING
THUNDERSTORMS. OVERALL, THE CONCERN FOR FLOODING IS LOWER TODAY,
BUT IF STRONGER AND/OR TRAINING CELLS OCCUR, ESPECIALLY OVER
AREAS THAT RECEIVED SEVERAL INCHES YESTERDAY, LOCALIZED FLOODING
WILL BE POSSIBLE. WPC MAINTAINS OUR SOUTHERN ZONES IN A
MARGINAL (LEVEL 1/4) RISK OF EXCESSIVE RAINFALL. SCATTERED
SHOWERS WILL REMAIN POSSIBLE THROUGH TONIGHT, MAINLY EAST OF
HIGHWAY 17 AND ALONG/NORTH OF HIGHWAY 264 WITH GREATEST CHANCES
NEAR THE COAST.
LOWS WILL BE SIMILAR TO LAST NIGHT WITH TEMPS BOTTOMING OUT
AROUND 70.
SHORT TERM /FRIDAY/
AS OF 3:10 PM THURSDAY...TOMORROW, THE OFFSHORE LOW WILL MOVE
TO THE NORTHEAST AND THE MID-LEVEL TROUGH WILL WEAKEN. WE'LL
HAVE A RINSE AND REPEAT OF TODAY WITH CLOUDY SKIES, GUSTY
NORTHEASTERLY WINDS, AND SCATTERED SHOWERS AND THUNDERSTORMS.
WITH PLENTIFUL MOISTURE CONTINUING TO STREAM INTO THE AREA,
LOCALIZED FLOODING FROM THUNDERSTORMS AND/OR TRAINING CELLS WILL
BE POSSIBLE. WPC HAS THE MAJORITY OF THE AREA IN A MARGINAL
(LEVEL 1/4) RISK OF EXCESSIVE RAINFALL WITH AREAS CLOSER TO THE
COAST BEING THE BEST CANDIDATES FOR THE HEAVIEST RAIN. AMOUNTS
OF 1-2" CAN BE EXPECTED IN THIS AREA WITH LOCALIZED AMOUNTS OF
3-4" POSSIBLE. PRECIPITATION COVERAGE AND AMOUNTS WILL DEPEND ON
OUR PROXIMITY TO AND THE STRENGTH OF THE OFFSHORE LOW.
HIGHS WILL REACH THE LOW- TO MID-80S.
LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/
AS OF 3 AM THU...
KEY MESSAGES
- BELOW NORMAL CONDITIONS CONTINUE INTO THIS WEEKEND
- UNSETTLED CONDITIONS CONTINUE FRIDAY, WITH MORE SCATTERED COVERAGE
OF SHOWERS AND STORMS EXPECTED THIS WEEKEND THROUGH EARLY
NEXT WEEK
- MORE TYPICAL SUMMER PATTERN RETURNS MONDAY THROUGH MID NEXT
WEEK
BY SATURDAY DRIER HIGH PRESSURE WILL REBUILD DOWN THE EASTERN
SEABOARD AS LOW PRESSURE PASSES BY WELL OFFSHORE. RAIN CHANCES WILL
HINGE ON THE STRENGTH AND DRYNESS OF THE COOL AIR ADVECTION COMING
IN FROM THE NORTH. WITH MORE OF THE GLOBAL GUIDANCE SHOWING A DRIER
SOLUTION, PRECIP CHANCES ARE DECREASING FOR SATURDAY. SIMILAR
CONDITIONS ARE ANTICIPATED SUNDAY WITH N/NE FLOW OVER THE AREA, AND
UNCERTAINTY IF THE INCOMING AIRMASS WILL BE DRY ENOUGH TO LIMIT
AFTERNOON CONVECTION.
HIGH PRESSURE WILL SHIFT OFFSHORE MONDAY AND A MORE TYPICAL SUMMER
PATTERN WILL DEVELOP THROUGH MID NEXT WEEK. PRECIP CHANCES WILL BE
NEAR CLIMO WITH UPPER LEVEL RIDGING MOVING OVER THE REGION. HEAT AND
HUMIDITY WILL BUILD EACH DAY, WITH HIGHS REACHING UPPER 80S TO LOW
90S, AND PEAK HEAT INDICES APPROACHING 100 DEGREES.
AVIATION /00Z FRIDAY THROUGH TUESDAY/
SHORT TERM /THROUGH FRI/...
AS OF 7:45 PM THURS...
KEY MESSAGES:
- PROLONGED SUB-VFR FLYING CONDITIONS POSSIBLE
NOT MUCH CHANGE IN THE FORECAST OUTSIDE OF TAKING OUT ANY
MENTION OF FOG TONIGHT AS SUB-VFR CONDITIONS WILL CONTINUE
ACROSS ENC INTO FRIDAY AS WE REMAIN UNDER A WEDGE OF HIGH
PRESSURE AND AMPLE LOW LEVEL MOISTURE CONTINUES TO STREAM INTO
THE REGION BRINGING WIDESPREAD LOW STRATUS.
CURRENT OBS SHOW 5-10 KT NORTHEASTERLY WINDS AND A MIXED BAG OF
FLIGHT CATS RANGING FROM VFR TO IFR. AS WE CONTINUE TO RESIDE
WITHIN THIS CAD REGIME, THE LOW CLOUDS AND ISOLATED SHOWERS
WILL LINGER THROUGH THE PERIOD, WITH HIGHEST CHANCES TO SEE
SHOWER ACTIVITY ALONG THE COAST AND OBX SOUTH OF OREGON INLET.
WHILE WE DO HAVE SOME VFR CEILINGS OUT ACROSS ENC TONIGHT
EXPECT CEILINGS TO QUICKLY BECOME MVFR BETWEEN 1.5-2.5 KFT AFTER
00Z TONIGHT AND REMAIN THAT WAY THROUGH AT LEAST 06Z. AFTER 06Z
THERE WILL ONCE AGAIN BE THE POTENTIAL FOR IFR CEILINGS. LIFR
CIGS CAN'T BE RULED OUT EITHER, ALTHOUGH CONFIDENCE IN
WIDESPREAD CIGS <500 FT IS NOT HIGH AT THIS TIME. WESTERN
TERMINALS (ISO AND PGV) WILL HAVE THE BEST CHANCE AT SEEING CIGS
THIS LOW. SIMILARLY TO TODAY, CONDITIONS WILL BE SLOW TO
IMPROVE AFTER THE SUN COMES UP. CIGS SHOULD RETURN TO MVFR BY
MID- TO LATE- MORNING BUT ARE EXPECTED TO REMAIN AT THAT LEVEL
THROUGH THE REST OF THE PERIOD. INCREASING SHOWER CHANCES
ESPECIALLY ACROSS OAJ/EWN BEGIN AFTER 18Z AND AS A RESULT HAVE
PUT IN SOME PROB30 GROUPS FOR SHOWERS AT THESE TERMINALS.
LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
AS OF 3 AM THU...UNSETTLED CONDITIONS FRIDAY COULD LEAD TO
EXTENDED PERIODS OF SUB-VFR CONDITIONS. PRECIP COVERAGE BECOMES
MORE SCATTERED THIS WEEKEND AND THROUGH EARLY NEXT WEEK, WITH
SOME BRIEF PERIODS OF SUB-VFR CONDITIONS POSSIBLE.
