Quiet weather expected for the rest of this afternoon and evening as eastern NC finds itself sitting on the northeastern periphery of a broad sub-tropical ridge centered over the Gulf. Unseasonably warm already as highs climb well into the upper 60s to near 70 inland, but northerly winds along the water are keeping OBX locales in the 50s.
Dry conditions expected tonight as high pressure crests over the region. Should see some good cooling tonight, although more robust radiational cooling will likely be hampered by increasing clouds ahead of approaching shortwave embedded in northwesterly flow aloft. Lows expected to bottom out in the 40s.

Clouds increase quickly after sunrise tomorrow as a weak disturbance moves across the NC/VA border and offshore. Forecast trends continue to favor a period of light rain (generally amounting to less than a couple tenths) across northern NC, with an isolated shower possible south of US 264. Temperatures will be slow to rise in the morning due to the clouds, but will jump up into the 60s to low 70s as skies clear in the afternoon and southwesterly flow ramps up ahead of another quick-hitting front.

High pressure ridge over the SE US breaks down temporarily Friday as an area of low pressure moves across the Mid-Atlantic. This will bring widespread cloudiness to ENC, and a warm front will skirt northern NC Friday night with scattered showers developing along it. Very light precip amounts expected, but areas along the Albemarle Sound and NOBX could pick up to a tenth of an inch of rain overnight. It will be cooler due to the clouds, with highs only reaching the mid to upper 50s.
High pressure ridge rebuilds over the weekend with very warm and dry conditions expected. Temps will climb to the upper 60s to low 70s, though chillier conditions are expected along the OBX.
A strong cold front is likely to move through the area Sunday or early Monday, and will bring much colder conditions to the Carolinas through early next week. Limited moisture will be available with this front, and only scattered areas of light rain expected as it moves through.
18z Wednesday through Monday As of 12 PM Christmas Eve, Mostly clear skies and light winds persist for most of the area early this afternoon. A batch of persistent clouds has developed and is lingering along the Albemarle Sound, as well as FEW-SCT high clouds passing through western locations. Winds are currently out of the NW at 5-10 kt and will become NE within the next hour or two as a dry front passes. Skies will gradually become more SCT-BKN with mid level clouds later in the overnight hours into Christmas morning. Scattered -SHRA will be possible after 12Z.
Outlook: Generally quiet through the end of the week with VFR conditions expected for much of ENC.
