349 FXUS62 KMHX 300541 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 1241 AM EST Sun Nov 30 2025 .SYNOPSIS... High pressure slides offshore tonight. A weak warm front will move north through ENC Sunday morning before a cold front crosses in the evening. Behind this system high pressure will briefly build in from the north Monday, with a stronger low pressure system expected to move across the Carolinas Tuesday. High pressure then rebuilds into the area from the north through midweek before another low pressure system impacts the region late next week. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... As of 1830 Saturday...Typical cold spots decoupled with sunset, have brought down hourly Ts to better capture this early evening T crash, which nudged the MinTs slightly lower. Still expecting Ts to stagnate, maybe rise latter half of the overnight. Previous Disco...as of 2:30 PM Sat... Key Messages... - Cold conditions expected again tonight with lows below freezing inland High pressure will gradually push offshore while a weak warm front/coastal trough begins to track north near the coast towards daybreak Sunday. As a result, some increasing cloud cover may approach the area near daybreak Sun with isolated to widely scattered showers also possible along the OBX. But, any inland areas will remain dry regardless of shower coverage. In addition to this, as the high pushes offshore, winds are forecast to shift to an E-SE direction overnight. This will allow for some moisture recovery overnight and some WAA. So what does this mean for the ambient weather for ENC tonight? The first is that we will likely have a pre-midnight low as temps drop rapidly into the upper 20s to low 30s inland and into the low 40s along the OBX just after sunset with temps then remaining steady and maybe even rising a few degrees after midnight and into daybreak Sunday as cloud cover and WAA increases. The second is the potential for some fog tonight. Right now guidance isn`t too keen on any fog development tonight outside of a few more pessimistic models like the RRFS which shows a bit more low level moisture recovery overnight. Currently discounting this however given how dry it has been and the amount of low level moisture needed to even get fog is on the higher end. With crossover temps too cold as well, leaning on a fog less night tonight. With all this in mind, while the threat is likely 10% or less can`t rule out some patchy fog completely yet, especially east of Hwy 17. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM MONDAY/... As of 230 PM Sat... Key Messages... - Rapidly moderating conditions Sunday as a warm front lifts through the area with highs in the mid to upper 60s possible - Isolated to scattered showers possible Sunday ahead of and along a cold front which will move through the area Sunday evening As the warm front lifts north through ENC Sunday morning, southerly flow begins in earnest behind the front. This is forecast to bring much warmer temps to the area with highs getting into the 60s on Sunday. A fair amount of clouds are likely with moisture increasing as well, but this should only act to limit temps from getting into the 70s on Sun. Continue to also see the signal for isolated to widely scattered showers ahead and along an incoming cold front. Cold front is forecast to sweep E`wards across ENC Sun evening/night. Have kept SChc to Chc PoP`s in the forecast given this, though rainfall amounts will likely be very light generally 0.15 inches or less. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... As of 245 PM Sat... Key Messages - A strong low pressure system will impact ENC Tuesday into Wednesday with the potential for heavy rain, gusty winds, and minor coastal flooding - Below normal conditions continue the rest of next week, with the potential for another low pressure system to move through the Carolinas late week An active weather pattern is shaping up early to mid next week. During this time, upper level troughing is forecast to develop across the central U.S., with southwesterly flow developing aloft across the southern U.S. At the SFC, a notably strong area of low pressure is forecast to develop along the Gulf Coast Monday, then lift NE through the Southeastern U.S. early next week. The majority of guidance continues to depict low pressure taking a "just" inland track as it moves through the Carolinas and up into the Mid-Atlantic. Though there remains some uncertainty with the track and intensity still, most model solutions show the potential for Gale Force winds and heavy rain. With this track we will be on the "warm" side of the low, but just barely. There remains potential for some convective elements and thunder, but this should be mostly confined to the immediate coast and over the nearshore marine waters. A plume of anomalous moisture and strong forcing, appears supportive of a period of moderate to heavy rain along the track of the low. Ensemble guidance and other forecast aids continue to show a notable signal for heavy rain (1-2"+). The rain is much needed as a large portion of ENC remains in a moderate drought. That said, some minor nuisance flooding cannot be ruled out for areas that see higher rainfall totals and/or higher rain rates. For coastal areas, especially the Outer Banks, we`ll have to closely monitor the potential for oceanside and soundside flooding impacts due to the potential for strong winds, large waves, and a higher tide cycle. High pressure briefly builds in towards the middle of the week, but this may be short-lived as yet another coastal low may impact the area towards the end of next week. Temperatures fall back down below normal Monday, but bounce back up on Tuesday. Below normal conditions then likely return for the rest of the week. && .AVIATION /06Z SUNDAY THROUGH THURSDAY/... As of 1230 AM Sunday...VFR flight cats prevailing through this afternoon for most, with sub-VFR chances increasing as a cold front moves through Sunday night. The SFC high continues to slide off the DelMarVA coast tonight, with low level flow slowly veering to SE Sunday morning, and eventually Sly Sunday afternoon ahead of an approaching cold front. Fog potential remains very low tonight despite gradual dewpoint recovery overnight as temps will remain well above cross-over temps. However, cannot completely rule out shallow ground fog, mainly across eastern rtes closer to the coast given near saturated conditions. Could also see stratus moving onshore late tonight into Sunday morning as low-level flow veers to SE nudging remnant boundary offshore toward the coast, bringing the potential for a period of MVFR CIGs along the coast. Probs remain quite low, generally less than 30% and will keep mentions to few-sct at coastal TAF sites. Could see a period of sub- VFR conditions with widely scattered showers ahead of a cold front Sunday evening. Have kept a sub FL050 cloud group for the afternoon timeframe, but still keep CIGs VFR for the time being. PoPs currently forecast less than 25% so no mention of SHRA for this afternoon. Slightly better chances of MVFR flight cats when cold front works through the FA from NW to SE Sunday night, with even a 20% chance of seeing brief drops to IFR. and some showers which could briefly reduce visibilities. Outlook: High pressure builds back into the area Monday with pred VFR conditions expected. Widespread sub- VFR likely Tuesday as a low pressure system is forecast to lift along the coast. High pressure builds back into the area Wednesday and Thursday with pred VFR conditions expected. && .MARINE... As of 245 PM Sat... Key Messages... - Small Craft conditions likely develop late Sunday night behind a cold front through most of Monday - Increasing potential for Gale Force winds Tuesday as a strong low pressure system moves over the Carolinas - Hazardous boating conditions will likely continue into Wednesday No big changes today in the forecast as relatively benign boating conditions are noted across our waters this afternoon with widespread 10-15 kt N`rly winds with 20 kt gusts and 2-4 ft seas noted across our waters today. Winds veer tonight to an east and then southeasterly direction as a weak warm front/coastal trough lift north across our waters Southerly winds increase to 10-20 kts Sunday afternoon, and then switch to the NW late Sunday night behind a cold front. Winds strengthen to NNW 15-25 kts with gusts to 30 kts overnight into Monday morning. Isolated to widely scattered showers will be possible as well along the warm front Sun morning and then again out ahead and along a cold front approaching from the west Sun evening/night. Seas will be mostly 2-3 ft through Sunday evening with seas then quickly building after midnight Mon from north to south to 4-6 ft. Outlook: Improving conditions expected after sunrise Monday, but this will be short lived as a strong low pressure system is expected to move through the coastal waters Tuesday. There is potential for Gale Force winds across much of the coastal waters, with the exact strength of the winds (and wind direction) still to be worked out. Hazardous marine conditions will continue for some time behind this system through Wednesday. && .TIDES/COASTAL FLOODING... As of 245 PM Sat...A strong low pressure system moving through North Carolina Tuesday will bring elevated winds and seas. This comes as we enter a king tide cycle Tuesday (12/2) through Monday (12/9) of next week. Areas with vulnerable dune structures along the Outer Banks have the potential to see minor coastal flooding, heightened during Tuesday evening`s and early Wednesday morning`s high tides. The forecast magnitude and direction of winds and waves with this system depends on the eventual track and strength of the low pressure system. And as a result, specific coastal flooding impacts and their severity are still unclear at this time. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None.
