019 FXUS62 KMHX 191727 CCA AFDMHX Area Forecast Discussion...CORRECTED National Weather Service Newport/Morehead City NC 1227 PM EST Wed Nov 19 2025 .SYNOPSIS... A quick moving front moves through today. A secondary backdoor cold front moves through early Thursday. High pressure then rebuilds offshore late this week with above normal temperatures returning. A frontal system will bring the next chance of rain this weekend, with cooler and drier conditions expected early next week. Another system brings a small chance for rain by mid week next week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... As of 2 AM Wed...Pre-midnight low was observed for most areas, before inc cirrus and an inc in low level srly flow ensued, with temps rising through the 40s and 50s towards daybreak. An area of light isentropically driven rain is still fcst to sweep ewrd through the Hwy 64 corridor, possibly as far south as the Hwy 264 corridor, through this morning. Otherwise, mo cloudy skies will become partly cloudy through the afternoon hours today, allowing for temps to warm into the 70s swrn zones to 60s nern zones as broad but light swrly flow will be in place. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/... As of 2 AM Wed...Reinforcing backdoor front will sweep through ENC late today and through this evening. A bank of stratus will sweep in behind the front later tonight as frontal inversion sets up. The clouds and nnerly breezes will keep temps mild overnight, with readings in the 40s expected. && .LONG TERM /THURSDAY THROUGH TUESDAY/... As of 3 AM Wed...Mainly mild conditions expected with above climo temps through mid next week. Chances for rain Fri night into Sat, and then again by mid next week. Thursday...Aforementioned frontal inversion will linger into the day, keeping weak in-situ CAD setup in place with lingering stratus. NAM is best at capturing this regime, and have inc cloud cover and lowered temps as a result. Later shifts have room to go a bit cooler, esp if the ovc conditions linger through much of the afternoon. For now, highs around 60 at best for most locales with light nerly flow continuing. Fri through Sat...Next frontal system moves in bringing light rain chances. Kept pops in the chc range for now, but latest 19/00Z ECM cont to be wettest and may have to inc pops eventually. Rain amts do not appear impressive, and little to no instability present, so kept thunder mention over the warmer Gulf waters where some instability resides. Sun through Tue...High pressure is then forecast to build in behind the early weekend front, with dry conditions ensuing. Zonal flow will be in place, so temps should be around avg during this period, with highs in the 60s and lows in the 40s. && .AVIATION /18Z WEDNESDAY THROUGH SUNDAY/... As of 1230 PM Wed... Key Messages - Low stratus expected to bring sub-VFR ceilings tonight behind the passage of a cold front VFR conditions prevail across ENC as of early Wednesday afternoon, with some mid-level clouds with bases of 7-10 kft working their way eastward across the area. A few light showers are noted across the northern tier of the of the forecast area. These will remain north of TAF sites but may bring brief periods of light showers to the northern Outer Banks. Conditions will continue to dry out as skies clear through the afternoon. High clouds will build back in this evening as a cold front pushes southward through the region. Winds will shift from generally westerly to northerly behind the front, generally remaining 10 kts or less. Low stratus is expected to build in behind this front tonight from northeast to southwest, bringing a period of sub- VFR ceilings to much of ENC. Guidance still differs on potential for low stratus to reach as far southwest as OAJ, but guidance has trended more pessimistic since earlier this morning. Thus, have opted for prevailing MVFR groups for all TAF sites as of this cycle. Where low stratus sets in, guidance suggests ceilings will drop further to IFR (and potentially LIFR) conditions, but with some uncertainty remaining amongst guidance regarding expanse and timing of low stratus, have opted to only include a FEW009 group at this time. Potential for IFR/LIFR ceilings will be monitored for future TAF cycles. There is some uncertainty regarding how quickly low stratus will mix out tomorrow morning, but current guidance suggests conditions will improve to VFR for TAF sites during the late morning hours, with sub-VFR ceilings lingering across the NOBX. Outlook: High pressure remains in place into Friday. Should winds ease enough, could see some VIS concerns with patchy early morning fog as well. Yet another chance for Sub-VFR conditions over the weekend when a series of approaching, and eventually passing, fronts increase rain chances and sky cover. && .MARINE... As of 2 AM Wed...Swrly flow early this morning in the 5-15 kt range (10-20 kt over the Gulf Stream). Cool front sweeps through late today into this evening, with winds turning nnerly generally 10-20 kt, with some ocnl gusts to 25 kt possible, but not widespread enough to warrant any sca headlines attm. Winds turn swrly on Fri night into early Sat ahead of next cold front. Some sca winds possible on the well mixed Gulf waters during this time, with remaining waters/sounds/rivers remaining well below criteria. Seas may briefly get to 6+ ft south of around C Hatteras this weekend with the swrly wind surge. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None.
