| Area Forecast Discussion National Weather Service Newport/Morehead City NC 733pm EDT Tuesday August 25 2026 .WHAT HAS CHANGED... Aviation section updated. No major changes to the forecast. .KEY MESSAGES... 1) Stalled front remains to the south today and tomorrow keeping shower and thunderstorm risk low through Wednesday. 2) Unsettled weather returns Thursday and into the weekend as a front wobbles back towards the coast. KEY MESSAGE 1...Cold front is stalled to the south of ENC with light N'rly flow bringing dry and "relatively" cooler air over the region this afternoon. Highs have gotten into the 80s today though it is less humid than previous days. As we get into tonight, winds look to once again decouple under mo clear skies as high pressure centered to the north slides E'wards towards the Eastern Seaboard. Low level moisture remains in place across portions of ENC especially across areas that saw rain on Monday. Given this, would not rule out the development of patchy fog or low stratus tonight after about midnight. Latest sounding data for this evening does look supportive for fog/low stratus development given a high potential for a low level inversion to develop thus trapping low level moisture in place. Will note there is one thing working against fog/low stratus development this evening which would be the continued advection of dry air today. For now to account for the uncertainty have capped visibility to 5 miles mainly along the Crystal Coast and left patchy fog in areas I have the highest confidence in for now. Further adjustments either up or down will likely be necessary to visibility tonight depending on trends. Otherwise lows tonight get into the upper 60s to low 70s. On Wednesday, surface flow becomes more onshore, kicking off a period of increasing moisture and instability Thursday onwards across the Southeast U.S. coastline with a modest uptick of shower and thunderstorm coverage as a wave of low pressure lifts a weak front northwards towards ENC. KEY MESSAGE 2...Another wave of low pressure is forecast to lift along the same front Thursday into Friday, pulling it further north into ENC and providing a better focal point for more widespread coverage of showers and storms ahead of a second front which will cross the area by Sat. Given the multiple days of onshore flow, PWATs (Precipitable Waters) do return back closer to 2" from Thurs onwards and with enough instability in place but a lack of shear, a few isolated stronger storms aren't completely out of the question though not currently anticipated. In addition to this, any shower or thunderstorm that develops will be an efficient rainmaker bringing torrential rainfall and a low end risk for flash flooding, mainly in urban and poor drainage areas. High pressure builds back in behind Sat's front on Sunday bringing a return back to more climatological precipitation chances along the seabreeze. Temps into next week remain seasonable with highs in the 80s and lows in the mid 60s to mid 70s. Marine Benign boating conditions continue this afternoon as N'rly winds at 5-10 kts slowly veer becoming E and then SE'rly at 5-10 kts by Wednesday morning across all our waters. Winds then remain SE'rly at about 5- 10 kts through the day Wednesday as a weak front which is currently stalled to the south begins to lift N'wards. Seas remain at 2-4 ft through Wednesday evening. While it will likely remain mainly dry and thunderstorm free across our waters this afternoon and tonight a slight increase in chances especially across the waters south of Cape Hatteras will be possible on Wednesday as a weak front begins to lift N'wards across the area waters. Outlook: Southerly flow remains in place from Wednesday night into the end of the week. Winds will increase slightly on Thurs night into Fri with the approach of a cold front closer to 10-20 kts with a few gusts up near 25 kts. Winds then ease for the weekend as high pressure begins to build in from the north and west. This brings a low end chance of SCA (Small Craft Advisory) conditions mainly along the coastal waters, but confidence is too low for SCA (Small Craft Advisory) headlines currently. Seas should generally hold around 2-4ft through Thursday, then build to 3-5ft on Fri. The risk of thunderstorms will be elevated on Thurs, Fri, and Sat as a wave of low pressure pushes a stalled boundary north back toward the coast with another front crossing the area Sat.
