231 FXUS62 KMHX 101139 AFDMHXArea Forecast Discussion National Weather Service Newport/Morehead City NC 739 AM EDT Wed Sep 10 2025
.SYNOPSIS... Low pressure will move north along a stalled frontal boundary just offshore of ENC today. High pressure will then build back in from the north and west through late in the week.
&&
.NEAR TERM /THROUGH TODAY/... As of 3 AM Wednesday...A stalled frontal boundary will persist off the coast today with an area of low pressure currently southeast of Cape Hatteras slowly lift NNE along the boundary today. Abundant low level moisture is advecting into the region bring widespread stratus across ENC and expect mainly cloudy skies to continue through the day. Southern area will have the best chance of seeing some breaks of sun this afternoon. Weak shortwave energy passing over the area and sfc convergence along a trough across the area could be sufficient to bring occasional light rain or drizzle across the area with best chances across coastal and northern sections of the FA where low level moisture will be deepest. QPF amounts are expected to be light with saturated conditions remaining below the dendritic growth zone. Temps will continue to be below normal with highs in the mid to upper 70s.
&&
.SHORT TERM /TONIGHT/... As of 330 AM Wednesday...Low pressure will lift away from the area tonight but the frontal boundary will remain offshore with high pressure centered to the north ridging into the area. Little change in sensible weather tonight with northerly winds and abundant moisture remaining trapped below a strong low level inversion bringing mostly cloudy skies and chances for light rain or drizzle continuing. Lows will be in the mid 60s inland to around 70 along the coast.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/... As of 4 AM Wednesday...
Key Messages
- Coastal trough lingers with much of the rainfall remaining offshore
- High pressure leads to drier conditions inland
A second high builds in from the Great Lakes region for Thursday. There are 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. At the minimum, winds should pick up a notch thanks to the tightened pressure gradient. This results in a higher degree of uncertainty for the forecast this weekend onwards.

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... SHORT TERM /through Tonight/... As of 730 AM Wednesday...
Key Messages
- Widespread sub VFR conditions through the short term.
A frontal boundary remains stalled just off the NC coast with an area of low pressure centered southeast of Cape Hatteras. The low will slowly move north-northeast off the coast today and lifting well away from the area tonight. Abundant low level moisture is advecting into ENC below a strong low level inversion bringing widespread stratus across rtes. Pred IFR cigs expected through this morning then is expected to lift to MVFR this afternoon. Cigs will lower again overnight with widespread IFR/LIFR expected. Moisture may be deep enough with weak forcing aloft as a shortwave moves over the area to bring light showers at times, especially across northern rtes. Northerly winds will continue through the period with gusts around 15-20 kt this afternoon.
LONG TERM /Thursday through Sunday/... As of 4 AM Wednesday...Lingering low ceilings are possible into Thursday. Thereafter, generally VFR flight conditions expected through the long term, with gusty N/NE winds along the coast.
&&
.MARINE... SHORT TERM /through Tonight/... As of 3 AM Wednesday...
Key Messages...
- Small Craft conditions continue north of Ocracoke Inlet through tonight for elevated seas.
Low pressure will slowly lift NNE along a stalled frontal boundary across the offshore waters today into tonight. Nly winds have diminished to around 10-20 kt last evening and will persist through the short term. Seas have also subsided to around 4-6 ft last evening, however, wave guidance continues to be about a foot underdone across the central and northern waters and adjusting accordingly, seas may linger around 6 ft north of Ocracoke Inlet into Thursday morning.
LONG TERM /Thursday through Sunday/... As of 430 AM Wednesday...
Key Messages:
-Gusty northerly winds continue through the long term
-Small Craft Advisory conditions return for the weekend
-High uncertainty in the marine forecast this weekend onwards
Seas continue to abate as winds ease into Thursday with seas 3-5 ft. Trough strengthens offshore, maybe resulting in a weak low, as we approach the weekend. This may result in gusty north/northeasterly winds 25-30kt late Friday into the weekend. However, winds and waves are highly dependent on strength, location, and track of low, should it even develop. As a result, higher than normal level of uncertainty with the magnitude of the winds at the end of the long term period.
&&
.TIDES/COASTAL FLOODING... As of 430 AM Wednesday...
Higher than normal astronomical tides will continue to produce elevated waters levels through most of the work week along the coast and tidal waterways from Ocracoke Inlet to Surf City. Depending on tide fluctuations, water levels will likely be 1 to 2 feet above ground level during periods of high tide. A coastal flood advisory remains in effect for portions of the Eastern North Carolina coastline for the higher tides.
&&
.MHX WATCHES/WARNINGS/ADVISORIES... NC...Coastal Flood Advisory until 11 PM EDT this evening for NCZ094- 194>196-199. Beach Hazards Statement from 7 AM EDT this morning through this evening for NCZ203. MARINE...Small Craft Advisory until noon EDT Thursday for AMZ150-152- 154. Small Craft Advisory until 4 AM EDT early this morning for AMZ156-158.
