453 FXUS62 KMHX 080622 AFDMHXArea Forecast Discussion National Weather Service Newport/Morehead City NC 222 AM EDT Mon Sep 8 2025
.SYNOPSIS... High pressure will build in from the north with a front stalled offshore early this week. A shortwave moves across the area with a surface low lifting along a stalled front offshore mid- week bringing heavy rain chances along the coast. High pressure builds in again for the end of the work week.
&&
.NEAR TERM /THROUGH TODAY/... As of 2 AM Monday...The frontal boundary remains stalled offshore near the Gulf Stream with high pressure building in from the north. Heavier precip has shifted offshore but weak isentropic lift is bringing additional light showers across the area, mainly across the NW third of the FA. The only model picking up on this is the HRRR and have followed it to capture the inland precip through the pre-dawn hours, which has the inland precip waning between 10-12z with weak isentropic down glide developing around that time.
Through the remainder of the day, expect mainly cloudy skies with the precip primarily remaining offshore near the stalled front but cannot rule out a few light showers skirting the coast at time. Locations west of highway 17 could see breaks of sun late this morning and afternoon. NE winds will gust to around 20 mph inland and 30 mph along the OBX. Temps will be around 5-8 degrees below normal with highs around 75-80 degrees.
&&
.SHORT TERM /TONIGHT/... As of 2 AM Monday...Little change in the pattern tonight with high pressure continuing to build in from the north and the front remaining stalled offshore near the Gulf Stream. Mostly cloudy skies persist along the coast with scattered clouds west of highway 17. Light to moderate NE winds persist across the area with gusts around 25-30 mph persisting along the coast. Lows expected around 60 well inland, low to mid 60s inland from the coast and upper 60s along the immediate coast.

.LONG TERM /TUESDAY THROUGH SUNDAY/... As of 1 AM Monday...
Key Messages
- Cooler, drier conditions this week
- Coastal trough lingers, best chances of rain Tue and Wed along OBX
- Dry end to the week as high pressure builds again
Front remains stalled along the Gulf Stream through the long term. NE flow behind the front as high pressure over the NE builds into the region, bringing a stretch of drier, and cooler conditions inland. A slightly stronger shortwave looks to move through along the coastal trough Tuesday into Wednesday. This will bring the best chances of showers reaching the coast, especially OBX where PoPs are highest. After the shortwave moves through, original high pressure over the NE gets pushed towards the Canadian Maritimes, and a second high builds in from the Great Lakes region. some indications of a weak low forming along the stalled front/coastal trough off the FL/GA/SC coast this coming weekend into early next week as a deep positively tilted trough moves through. It is too soon to tell what impacts, if any, are expected with very low confidence on the timing, track, and intensity of the low should it form.

.AVIATION /06Z MONDAY THROUGH FRIDAY/... SHORT TERM /through Tonight/... As of 2 AM Monday...Widespread stcu will persist across rtes through the short term as a strong low level inversion has developed behind a cold front that has stalled offshore and high pressure building in from the north. Cigs have lifted to VFR well inland, including ISO and PGV and expect VFR conditions to persist here through tonight. MVFR cigs persists at coastal TAF sites and guidance is indicating cigs will lift to VFR here around mid morning with VFR prevailing through tonight. Along the coast, east of the TAF sites, MVFR cigs expected to persist through much of the period. NE winds will gust to around 20 kt inland and 30 kt along the coast today.
LONG TERM /Tuesday through Friday/... As of 130 AM Monday...Low stratus possible as northerly flow may result in a cold air damming regime along the coastal plain this coming week. Tuesday into Wednesday rain chances with drops in cig and vis pick up along the coast.
&&
.MARINE... SHORT TERM /through Tonight/... As of 215 AM Monday...Gusty NE winds will continue through the short term as gradients remain tight between a stalled front near the Gulf Stream and high pressure building in from the north. NE winds will increase to around 20-25 kt with gusts around 30 kt by daybreak today and persist through the short term period. Seas will build to 5-8 ft by late today and tonight.
LONG TERM /Tuesday through Friday/... As of 130 AM Monday...
Key Messages:
- Prolonged period of SCA conditions likely to continue Tuesday into Tuesday night
- Winds fall below 25kts Wednesday, but near Small Craft Advisory conditions continue through the remainder of the work week
- Best chance for next round of SCA conditions late this week
Moderate NNE flow post frontal flow continues at 20-25 kt (gusting to at or above 30 kts) Tue. Seas will remain at 4-8 ft Tuesday. Seas abate as winds ease late Tuesday into Wednesday, with southern waters (Onslow Bay) first to see sub 6ft seas as early as Tuesday night. Northern waters (off of NOBX) may not see sub-6ft seas until mid to late day Wednesday. Even as these winds lessen, they will be 15-25kt out of the NE through the workweek. Tuesday into Wednesday shortwave moves through along a lingering coastal trough, increasing precip chances for areas along the coast and coastal waters.
