AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC
949 PM EDT WED MAY 28 2025
SYNOPSIS
CONDITIONS LOOK TO REMAIN UNSETTLED INTO THE END OF THE WEEK AS
MULTIPLE FRONTS IMPACT THE AREA. A STRONG COLD FRONT SWEEPS
THROUGH FRIDAY NIGHT, WITH HIGH PRESSURE BUILDING INTO THE
EASTERN SEABOARD BY THE WEEKEND BRINGING COOLER AND DRIER
CONDITIONS TO THE REGION.
NEAR TERM /OVERNIGHT/
AS OF 950 PM WED...NO SIGNIFICANT CHANGES NEEDED TO PREVIOUS
FORECAST FOR EARLY EVE UPDATE. EARLIER ISO COASTAL SHOWERS
BEGINNING TO WANE LATE THIS EVENING. OVERNIGHT, THE ATTENTION
TURNS TO PATCHY FOG DEVELOPMENT. MIXED SIGNALS FROM GUIDANCE
CONCERNING COVERAGE AND DENSITY. EARLIER RAINS COUPLED WITH A
STILL-MOIST BNDRY LAYER AND LIGHT/CALM WINDS IN WAKE OF WEAK
FROPA WOULD ACT TO CAUSE FOG TO DEVELOP. HOWEVER, OCNL MID AND
HIGH CLOUDS WOULD ACT TO PROHIBIT DEVELOPMENT. HAVE HANDLED THE
UNCERTAINTY WITH JUST A PATCHY MENTION IN THE FCST GRIDS, WITH
VSBYS NO LOWER THAN ~2SM ATTM. LOWS STILL VERY MILD, WITH
READINGS IN THE 60S.
SHORT TERM /THURSDAY/
AS OF 3 PM WED...WARM AND HUMID CONDITIONS EXPECTED WITH SCT
THUNDERSTORMS IN THE AFTERNOON, SOME OF WHICH MAY BE STRONG TO
SEVERE. MUCH WILL DEPEND ON HOW QUICKLY MORNING FOG, LOW STRATUS
WILL BURN OFF, BUT ATMS WILL BE CONDUCIVE TO SCT STORMS
DEVELOPING IN THE AFTERNOON. SHORTWAVE ENERGY ALOFT TRAVERSING
THROUGH THE MID SOUTH WILL PROVIDE THE UPR SUPPORT FOR THIS,
WHILE INLAND PROPAGATING SEA BREEZE WILL BE A FOCUS FOR LOW
LEVEL LIFT/CONVERGENCE. APPRECIABLE SFC BASED INSTABILITY ON THE
ORDER OF 1500-2000 J/KG COUPLED WITH EFF SHEAR OF 30+ KT WOULD
PROVIDE THE INGREDIENTS FOR ORGANIZED THUNDERSTORM DEVELOPMENT,
WITH COVERAGE MOST LIKELY ALONG THE SEA BREEZE JUST INLAND FROM
THE COAST, WITH SOMEWHAT LESSER CHANCES DEEP INLAND AND FOR
LOCALES ON THE IMMEDIATE COAST. HAVE 30-40% CHANCES FOR THUNDER
INLAND, WITH 20% CTRL/SRN OBX/CRYSTAL COAST REGION. SEVERE
THREATS WOULD BE STRONG TO LOCALLY DAMAGING WIND GUSTS AND LARGE
HAIL. HIGHS WARM AND MUGGY IN THE 80-85 DEGREE RANGE FOR MOST.
LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/
AS OF 415 AM WED...
KEY MESSAGES:
-UNSETTLED PATTERN CONTINUES THROUGH FRIDAY WITH PERIODS OF RAIN AND
THUNDERSTORMS EXPECTED.
- DRIER CONDITIONS SETTING UP FOR THE WEEKEND.
- WARMING TREND NEXT WEEK WITH TEMPERATURES CLIMBING WELL INTO THE
80S.
FRIDAY...A SURFACE LOW FORMING OVER KY AND CROSSING THE
APPALACHIANS INTO VA WILL BE THE PRIMARY DRIVER OF ACTIVITY ON
FRIDAY WHICH WILL NOT ONLY SEE THE BEST CHANCES FOR RAIN BUT FOR
THUNDERSTORMS AS WELL. THE POSSIBILITY OF SEVERE STORMS WILL BE
IN PLAY AS SPC HAS THE AREA IN A DAY 4 15% CHANCE FOR SEVERE
WEATHER. WHILE THE DETAILS ARE STILL TO BE WORKED OUT, THE
SYNOPTICS OF THE SYSTEM ARE IN PLACE AS THE UPPER TROUGH DIGS
AND BECOMES NEGATIVELY TILTED BY SATURDAY MORNING. THE QUESTION,
HOWEVER, IS WILL THE BULK OF THE CONVECTIVE ACTIVITY BE
OFFSHORE BY THEN.
AFTER THE FRONT MOVES OFFSHORE MUCH OF THE WEEKEND SHOULD BE DRY.
THERE IS ANOTHER WAVE THAT APPROACHES THE AREA FROM THE NORTH
ON SUNDAY MORNING BUT IT SHOULD BE DRY WHEN IT PASSES OVERHEAD.
A WARMING TREND CAN BE EXPECTED EARLY NEXT WEEK AS TEMPERATURES RISE
WELL INTO THE 80S.
