AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC
358 PM EDT FRI JUL 24 2026
WHAT HAS CHANGED
THE ENTIRE FLOOD WATCH HAS BEEN EXTENDED THROUGH SATURDAY
EVENING.
KEY MESSAGES
1) MULTIPLE ROUNDS OF SHOWERS AND THUNDERSTORMS EXPECTED TO
IMPACT EASTERN NC THROUGH SATURDAY EVENING WITH A RISK OF
FLOODING AND A FEW INSTANCES OF FLASH FLOODING.
2) WEAKER COLD FRONT APPROACHES CAROLINAS IN THE MIDDLE OF NEXT
WEEK, WITH A RETURN OF OPPRESSIVE HEAT AND RENEWED ROUND OF
SHOWERS AND THUNDERSTORMS.
DISCUSSION
KEY MESSAGE 1...THIS AFTERNOON, A STALLED FRONT STRETCHES
SOUTHWEST ALONG THE COAST OF THE CAROLINAS. MEANWHILE, THE MCV
AND AN ASSOCIATED SURFACE LOW THAT BROUGHT ALL OF THE RAIN TO
ENC EARLIER TODAY IS MOVING OFF THE COAST OF ENC. PERHAPS A BIT
OF SUBSIDENCE IN THE WAKE OF THAT FEATURE, PLUS REDUCED FORCING,
APPEARS TO BE THE REASON FOR AN OVERALL LACK OF CONVECTION AT
THIS TIME. THE ONE EXCEPTION IS ALONG THE CRYSTAL COAST WHERE
LOW-LEVEL CONVERGENCE IS BEING MAXIMIZED ALONG THE STALLED
FRONT, SUPPORTING ONGOING AREAS OF MODERATE TO HEAVY RAIN AND A
FEW THUNDERSTORMS.
THE CRYSTAL COAST CONVECTION SHOULD PERSIST THROUGH AT LEAST
SUNSET, BUT MAY WANE SOME WITH THE LOSS OF DAYTIME HEATING.
LATER TONIGHT, THE NEXT SHORTWAVE TO RIDE ALONG THE STALLED
FRONT WILL ENCROACH ON THE AREA. GUIDANCE SUGGESTS THE INCREASED
FORCING AMID A VERY MOIST AIRMASS SHOULD SUPPORT A RENEWED
UPTICK IN CONVECTIVE COVERAGE AND INTENSITY, AND GUIDANCE NOW
SHOWS THIS LASTING THROUGH MUCH OF THE DAY SATURDAY. ENSEMBLE
GUIDANCE DIFFER ON THE PLACEMENT OF THE HEAVIEST RAIN, BUT THERE
IS A PRETTY SOLID SIGNAL FOR ANOTHER 1-3" FOR MUCH OF ENC
THROUGH SATURDAY AFTERNOON, WITH A REASONABLE WORST CASE OF
ANOTHER 4-8" WHERE RAINFALL RATES ARE THE MOST
PERSISTENT/INTENSE. GIVEN UNCERTAINTY IN THE PLACEMENT OF THE
HEAVIEST RAIN, AND GIVEN HOW SATURATED PARTS OF THE AREA ARE,
AND HOW SENSITIVE SOILS MAY NOW BE, THE FLOOD WATCH HAS BEEN
EXTENDED OUT THROUGH 8PM SATURDAY FOR THE ENTIRE AREA. WITHIN
THE WATCH AREA, THERE WILL CONTINUE TO BE A RISK OF
MINOR/NUISANCE FLOODING, BUT WITH A CONTINUED RISK OF A FEW
INSTANCES OF FLASH FLOODING. ADDITIONALLY, WE'VE RECEIVED SOME
REPORTS OF TREES COMING DOWN IN THE ABSENCE OF MUCH WIND, AND
THIS IS LIKELY DUE TO SATURATED SOILS, NOT STRONG WINDS. THIS
MAY CONTINUE TO BE A RISK, ESPECIALLY FOR AREAS THAT HAVE SEEN
THE MOST RAINFALL OVER THE PAST 24-36 HOURS.
LASTLY, RIGHT ALONG THE FRONT THERE MAY CONTINUE TO BE JUST
ENOUGH OVERLAP OF SHEAR AND INSTABILITY TO SUPPORT A FEW WEAKLY
ROTATING UPDRAFTS WITH A GUSTY WIND AND WEAK TORNADO POTENTIAL.
THE RISK OF SEVERE WEATHER LOOKS LOW, BUT ISN'T ZERO.
KEY MESSAGE 2...WITH SUNDAY AND MONDAY TRENDING DRIER WITH THE
LINGERING FRONT FINALLY GETTING CARRIED OFFSHORE, FOCUS THEN
TURNS TO ANOTHER FRONT APPROACHING THE EASTERN CONUS NEXT MID-
WEEK. THIS BOUNDARY APPEARS WEAKER AND MORE PROGRESSIVE THAN OUR
CURRENT BOUNDARY BUT WILL STILL PROVIDE A FOCUS FOR SHOWERS AND
THUNDERSTORMS. AHEAD OF THE BOUNDARY, STRENGTHENING
SOUTHWESTERLY FLOW AND BUILDING LOW-LEVEL THICKNESSES WILL BRING
A RETURN OF OPPRESSIVE HEAT WITH AT LEAST A COUPLE DAYS OF HEAT
INDICES APPROACHING OR EXCEEDING 105F POSSIBLE.
AVIATION /19Z FRIDAY THROUGH WEDNESDAY/
SHRA AND TSRA WILL MAINLY BE FOCUSED FROM KOAJ TO KEWN OVER THE
NEXT FEW HOURS. THEN, AFTER 00Z THIS EVENING, THE SHRA AND TSRA
RISK SHOULD BEGIN TO EXPAND BACK NORTH AGAIN TO INCLUDE ALL TAF
SITES. DURING THIS TIME, LIFR/IFR VIS WILL BE POSSIBLE WHERE RA
IS THE HEAVIEST. ADDITIONALLY, PERIODS OF LIFR/IFR CIGS WILL
REMAIN POSSIBLE DUE TO WIDESPREAD LOW STRATUS. OUTLOOK (FRIDAY
NIGHT THROUGH TUESDAY): SUB-VFR CONDITIONS IN SHRA AND LOW CIGS
WILL CONTINUE TO PLAGUE ENC THROUGH TOMORROW AS A FRONTAL
BOUNDARY REMAINS STALLED OVER THE AREA. THE FRONT IS FORECAST TO
FINALLY SHIFT SOUTH OF ENC FROM NORTH TO SOUTH ON SAT WITH
GRADUALLY IMPROVING AVIATION CONDITIONS BY SUNDAY.
OUTLOOK (SATURDAY NIGHT THROUGH WEDNESDAY): A COLD FRONT IS
FORECAST TO FINALLY SHIFT SOUTH OF ENC FROM NORTH TO SOUTH
SATURDAY NIGHT WITH GRADUALLY IMPROVING AVIATION CONDITIONS BY
SUNDAY.
MARINE
COLD FRONT IS CURRENTLY STALLED OVER ONSLOW BAY THIS MORNING
WITH REGIONAL OBSERVATIONS SHOWING WINDS AT AROUND 10 KT OR
LESS. GRADIENT WILL REMAIN RELAXED AROUND THE FRONT AS IT MOVES
LITTLE THROUGH TODAY, PERHAPS LIFTING NORTHWARD SLIGHTLY LATER
TONIGHT. WINDS AND SEAS WILL REMAIN SAFELY BELOW SCA THROUGH THE
PERIOD BUT MULTIPLE ROUNDS OF WIDESPREAD RAIN AND THE
OCCASIONAL THUNDERSTORM WILL CONTINUE TO PLAGUE AREA WATERS INTO
SATURDAY MORNING.
OUTLOOK: A STALLED FRONT WILL FINALLY SHIFT OFFSHORE BY
SATURDAY NIGHT, WITH MODERATE NORTHERLY WINDS DEVELOPING FOR
ALL WATERS BY SUNDAY. THE RISK OF THUNDERSTORMS IS EXPECTED TO
DECREASE ON SUNDAY AS WELL. A MORE TYPICAL SUMMERTIME WIND AND
SEA PATTERN THEN RETURNS NEXT WEEK.
