025 FXUS62 KMHX 310830 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 330 AM EST Fri Jan 31 2025 .SYNOPSIS... A strong cold front moves through tonight. High pressure then rebuilds over the area Saturday through early next week. && .NEAR TERM /THROUGH TODAY/... As of 330 AM Fri...Today will be a beautiful end to the month of January with unseasonable high temperatures well into the mid 70s across the coastal plain. Record highs are in the upper 70s to around 80 for most interior locales, and could get close for some. No such luck for the coastal areas, as the past cold wave has left area water temperatures only in the 40s to around 50. A strong onshore breeze will keep temps much cooler, only in the low/mid 60s here. Strong southwesterly flow will pump in ample moisture, which will more than double the dew points for the coastal plain from what they are today (mid-20s today, near 60 today). This increase in temperatures and dew points will be thanks to a warm front lifting north across the area with a strong cold front approaching from the TN/OH Valley. The region will be entrenched in the warm sector, so dry conditions expected. Winds will be quite gusty, with a well- mixed bndry layer and strong llj dynamics leading to sfc transport of these wind gusts. NBM probs for wind gusts up to 30 mph are quite high, 50-75% across the interior zones, and have bumped up wind gusts to 25-27 kt inland. Near the coast, strong marine inversion will be in place with the cold waters, so wind gusts are lower for the nearshore areas as well as Pamlico sound and nrn OBX. && .SHORT TERM /TONIGHT/... As of 330 AM Fri...The aforementioned cold front will move through ENC late tonight. Ahead of it, strong gradient remains in place, and in fact, llj sharpens and inc to 60+ kt in the 850-925mb layer. While sfc heating abates with the loss of solar insolation, good bdry layer mixing still in place, and gusty gradient winds to 30 mph or higher will remain. the strongly forced front with layer streamlines off the GOM will bring a period of heavy rain showers to the area ahead of the fropa, and categorical pops remain in place. While no instability, and thus no thunder is expected, momentum transfer with heavier showers will bring brief gusts over 40-45 mph. Rain and wind abate quickly from w to e late tonight as the front races offshore. && .LONG TERM /SATURDAY THROUGH THURSDAY/... As of 245 AM Fri...Mostly dry and seasonable this weekend, with temperatures warming next week. Saturday and Sunday...The cold front will be well offshore by sunrise Sat, and therefore a dry fcst will continue for most of the weekend with high pressure building in. Will continue a very low chance for a lingering coastal shower early Sat, with precip chances ending quickly. On Sunday a weak coastal trough may move close enough to the coast to produce isolated coastal showers late Sunday into Sunday night. Since most of the guidance remains dry, will continue to leave mention of precipitation out of the forecast for now. Temps a few degrees cooler this weekend with post frontal N-NE winds. Highs Sat and Sun in the 50s to low 60s inland and 50s for the Outer Banks. Monday through Thursday...High pressure remains anchored over the SE Monday, with nearly zonal flow aloft. The high will weaken Tuesday as a weak boundary is expected to push through. A stronger front will approach the area mid to late week, with precip chances increasing. Will continue the sc pop mention mid to late week. Above normal temps expected through the period with highs mainly in the 60s/70s. && .AVIATION /07Z FRIDAY THROUGH TUESDAY/... SHORT TERM /through tonight/... As of 2 AM Fri...Warm front lifting through is bringing a deck of clouds to ENC, though cigs in the VFR range. Sct/bkn 3.5k ft deck will lift to mid and high clouds during the day today as warm front moves north of ENC. LLWS is in place early this morning as strong southwesterly flow aloft will support a 35-40 kt LLJ over inland terminals with the wind shear threat ending around 12/13Z this morning as daytime heating commences. The tradeoff will be gusty winds today as strong heating will be in place. Sswrly wind gusts over 25 kt are expected today, lasting into this evening ahead of a strong cold front approaching. A period of mod to heavy rain showers will move through ENC after around 4Z, moving quickly off the coast by 10Z. With the rain, reductions in vsby and cigs to IFR are possible. LONG TERM /Saturday through Tuesday/... As of 245 AM Fri...Sub-VFR cigs possible Sunday with coastal troughing offshore. Otherwise, expect pred VFR conditions through the period with high pressure in control. && .MARINE... SHORT TERM /through tonight/... As of 330 AM Fri...Gradient is inc early this morning ahead of approaching cold front to the west. The gradient will be strongest over the Gulf Stream as good mixing occurs with the warmer waters. For the nearshore and sounds, strong marine inversion will be in place today with the warming airmass over the cold waters. Based fcst heavily on CMCreg, which initializes area water temps correctly. Low end SCA conditions will develop by afternoon for the waters/sounds/rivers with gusts aoa 25 kt expected. Strong daytime heating inland will bring locally stronger gusts possible to the land/water interface esp for the inland rivers, Alligator River, and wrn Albemarle sound. THe gradient inc further overnight, and solid gales are expected for the coastal waters sound of Oregon Inlet with gusts of 40 kt or higher expected. Elsewhere, the SCA will cont with gusts of 25-30 kt. Some isolated thunderstorms are possible over the outer warmer waters esp south of C Hatteras late tonight. Seas will peak in the 8-10 ft range for the Gulf waters overnight. Winds quickly abate late tonight as the strong cold front sweeps offshore. LONG TERM /Saturday through Tuesday/... As of 245 AM Fri...A secondary front will cross the waters Sat resulting N winds increasing to 15-25 kt and elevated seas 4-7 ft. SCAs likely to continue through late evening. High pressure will build over the waters Sunday into early next week with better marine conditions. N-NE winds 10-15 kt and seas 3-5 ft Sun. Flow veers around becoming SW 5-15 kt Mon with seas 2-4 ft. A weak boundary may push through the waters Tuesday with flow becoming W-N 5-15 kt. && .CLIMATE...
