Discussion

KEY MESSAGE 1: A dry cold front will move south across the region tonight; followed by near normal temperatures, breezy conditions and marine headlines.

Weak surface high pressure and ridging aloft will lead to one more day with temperatures above normal and light winds. A dry cold front will move south across the area tonight. Northeast winds will increase following the passage of the front, after midnight. High pressure building down the coast this weekend will drop temperatures near normal. Gusty winds Sat decrease in the afternoon as winds aloft weaken and drop off in the evening due to loss of heating/mixing. Another northeast surge arrives late Sat night leading to an increase in gusts again on Sun.

What had looked like a potential rain event for the start of next week has turned dry. Most of the guidance has now backed off on rain for the local area. The GFS is stubbornly holding onto rainfall Sun night into Mon, but this setup/pattern is typically one where the areas ends up dry. Gulf Coast convection in conjunction with a weak shortwave lifting northeast through the OH Valley almost always leads to little to no rainfall for the eastern Carolinas. The convection to the southwest will blossom off the FL East Coast and then travel northeast, passing just offshore.

Rain chances the middle of next week look better, but still have low confidence. Some big disagreements between the GFS/EC/CMC with the evolution of the pattern aloft and sharp 5h trough vs cutoff low. Cutoff lows are notoriously difficult to pin down, especially 6 or 7 days out.

Despite decreased winds tidal anomalies are still running around 1 foot, which has once again required issuance of Coastal Flood Advisories for the area, the coast and the Lower Cape Fear River, for the midday-ish high tide.

Aviation

Generally VFR, with patchy early morning fog/stratus mixing out quickly as the sun rises. Light northeast winds through tonight with a few high clouds.

Extended Outlook: VFR through Sunday. Potential for MVFR ceilings Monday and Tuesday.

Marine

Weak high pressure today will be reinforced by the passage of a backdoor cold front tonight into Saturday. Winds may exceed Small Craft thresholds across the coastal waters and seas will exceed 6 ft resulting in another long duration Small Craft event. Much uncertainty exists by early next week. However, maritime conditions will most likely not be favorable through Tuesday given the resiliency of the fetch. While 4-7 ft seas will be common across the coastal waters seas will be steeper offshore aided by the fetch direction and the Gulf Stream. Increasing chances for showers and possible a few thunderstorms, especially for the offshore waters early next week.
