243 FXUS62 KMHX 181919 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 219 PM EST Tue Nov 18 2025 .SYNOPSIS... High pressure will slide offshore tonight, with a quick moving front moving through the area tomorrow morning. High pressure then rebuilds offshore late this week with above normal conditions returning. A frontal system will bring the next chance of rain this weekend, with cooler and drier conditions expected early next week. && .NEAR TERM /THROUGH TOMORROW MORNING/... As of 2 PM Tue...Dry and clear conditions continue early this afternoon with high pressure overhead. Temps have risen into the mid to upper 60s, but with dewpoints down in the 20s again, RHs have fallen into the 20-25% range. However, the absence of wind should limit the fire danger this afternoon. Skies will continue to be clear this evening as high pressure shifts offshore. We could see another period of rapidly falling temperatures with ideal radiational cooling conditions before winds pick up and clouds roll in later tonight. Temps will fall into the low to mid 40s this evening and then hold steady or even rise overnight. A quick moving weak front will move in from the west overnight, dropping a front southward as the associated low pressure races eastward over the southern Mid-Atlantic coast. Though this system will not have much moisture to work with, guidance (especially hi-res) continue to indicate enough mid and low level moisture will be present to eek out some scattered showers (30-40% chance) early tomorrow morning through late morning. Best chances for any light rain will be across the northern half of the forecast area, mostly north of US 264, with points southward likely remaining dry. && .SHORT TERM /WEDNESDAY AFTERNOON/... As of 2 PM Tue... Behind a weak cold front we will retain some clouds into tomorrow afternoon, which will slow heating. However, increasing thicknesses will allow for above normal conditions to develop, especially across southern NC where clouds will be more scattered. Expect highs to range from the mid to upper 70s along and south of US 70, to the upper 60s to around 70 adjacent to the Albemarle Sound region, where clouds will linger the longest. && .LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/... As of 2 PM Tue... Key Messages: - Extended period of above normal temperatures appears likely into this weekend - Next frontal system expected this weekend Upper ridging builds over the Southeast from Wed evening on into the end of the week. A weak and dampening upper level trough looks to eject from a closed low over SoCal this weekend potentially bringing our next frontal system and precip to ENC. Aforementioned upper level closed low makes its way into the Plains by early next week, though forecast uncertainty remains high with this feature given guidance remains fairly spread on the overall evolution of the closed low over the next several days. Temps will remain above avg through the rest of the week as high pressure builds back into the Mid- Atlantic and S`rly flow resumes. An incoming upper trough this weekend could bring a frontal system to ENC which would bring a better chance at some precip, though given larger than avg uncertainty in the forecast, exact details still need to be hashed out. For now keeping precip chances at Chc to SChc starting late Fri night and persisting into Sun morning, though as timing gets nailed down for exact impacts to ENC expect the precip window to shrink some compared to whats currently forecast. High pressure is then forecast to build in behind whatever frontal system impacts ENC early next week. Temps continue to around average going into early next week. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... As of 1300 Tuesday... Key Messages: - VFR conditions expected through the TAF period - LLWS concerns late tonight High pressure centered just N of the FA currently pushing offshore of the NC/VA border will continue to creep Eward through the TAF period. VFR flight cats prevailing through the period under mainly clear skies through the rest of the day and into tonight. Light and variable winds becoming more Serly this evening, SWerly overnight, generally around 5 kt or less. A shortwave trough and attendant warm front lift through the area tonight which will bring lowering CIGs with isolated to widely scattered showers across Nern rtes after midnight into Wednesday morning. Almost all available guidance keeps CIG>FL030 for TAF sites with prob of sub VFR below 35%, but MVFR CIGs are more likely over OBX. Sfc winds remain light southerly tonight but the system will bring a strengthening low-level jet which may bring LLWS concerns across the coastal plain after 07z, mainly affecting PGV and ISO. The cold front associated with the SFC low will sink through the FA through WED turning winds Nerly in its wake in the evening. Outlook: High pressure builds in Wednesday night into Friday with pred VFR expected, however select guidance is highlighting potential for post-frontal low level stratus sinking from N to S in the overnight hours. Should winds ease enough, could see some VIS concerns with patchy early morning fog as well. Next chance for SubVFR over the weekend when a series of approaching, and eventually passing, fronts increase rain chances and sky cover. && .MARINE... As of 2 PM Tue... Key Messages - Benign boating conditions generally forecast into the end of the workweek - Small craft conditions possible this weekend Light and variable winds continue this afternoon. Tonight winds will come around to the S/SW at 10-20 kts (with a few gusts to 25 kts) ahead of a weak front. Behind the front tomorrow winds will switch around to the N/NNE at 10-20 kts. Seas will be 2-4 ft. Outlook: Northerly winds continue Thursday at 10-15 kts, with winds coming back around to the SW Friday at 10-20 kts. There is potential for Small Craft conditions to develop ahead of and behind a frontal system Saturday into Sunday. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None.
