| Area Forecast Discussion National Weather Service Newport/Morehead City NC 742pm EDT Sunday August 23 2026 .WHAT HAS CHANGED... No significant forecast or messaging changes. .KEY MESSAGES... 1) Localized severe threat for coastal areas remains this afternoon and will linger into Monday. Monday's threat may impact areas farther inland. 2) Reduced thunderstorm risk possible Tuesday and Wednesday, with unsettled weather returning by late week KEY MESSAGE 1...Cold front is expected to stall along the coast as overall forcing weakens and shifts away from the region. With a more stable airmass in place behind the sea breeze and dry air aloft, thunderstorm chances are quickly diminishing for the rest of the evening. However, some overnight redevelopment of showers and storms is possible as the front will remain in the area, and elevated instability will remain abundant. Overall moisture is not as deep as the past few days and the overall flooding threat is comparatively lower. Guidance continues to depict a weak surface low lifting NE along the frontal boundary tomorrow (the low may actually subtly pull the boundary farther inland as it progresses). Overall pre-storm environment will be similar tomorrow, sans a modest uptick in effective shear in the vicinity of the low. This may provide a marginally better environment for supercell development. If the front does get pulled west, the convective risk will also follow suit. The greatest risk of strong to severe thunderstorms remains east of HWY 17 with damaging winds remaining the primary threat, with hail possible in supercells. KEY MESSAGE 2...Guidance still struggling on whether or not the airmass can fully dry out Tuesday and Wednesday as our current frontal boundary may still be stalled nearby. Isolated showers and storms cannot be ruled out but coverage is likely to be far sparser than the past few days. Moisture and instability then begin to rebuild across the Southeast U.S. coastline with the potential for another round of unsettled weather. Marine A cold front approaches area waters this afternoon, stalling across the area over the next couple of days. A couple of weak areas of low pressure are then forecast to lift northeast along the front tonight and tomorrow, favoring periods of thunderstorms in the overnight and early morning. Varying wind directions are expected as the pair of lows move through, but neither low looks all that strong. For the coastal waters, seas of 2-3 ft are expected today through tomorrow. Outlook: Winds will become northeasterly for a brief time on Tuesday before southerly flow returns by the middle of the week, and lasting into the end of the week. Seas should generally hold around 2-3ft through Thursday, then build to 3-5ft late in the week. The risk of thunderstorms may decrease some Tuesday and Wednesday before increasing again later in the week. NOAA Newport/Morehead City NC Office - Watches - Warnings - Advisories NC...None.
