Synopsis
A coastal trough will lift north across the area this evening. A stronger cold front with limited moisture will cross Monday night. Low pressure with plentiful moisture will move northeast and impact the region mid next week.

Near Term - Until 6am Monday Morning
As of 1005pm Sun...A coastal trough remains just off the Outer Banks late this evening, and will remain so until eventually lifting to the northeast overnight. The region will then remain under weak southerly flow through tomorrow morning between the coastal trough and an approaching frontal system to the west.

Mostly benign weather will continue.nue however, the anticipated development of widespread fog and low stratus will complicate the overnight weather conditions. Skies will continue.nue to clear this evening, allowing for temps to cool into the upper 40s to low 50s inland from the coast. This cooling will combine with higher moisture that has advected into the area today, and allow for the formation of fog, first over the southern NC coastal plain, and then pushing northward through the early morning hours to cover most of Eastern NC west of US 17. With a sizable low level saturated layer present, fog is expected to become very dense at times early tomorrow morning, and will be very slow to burn off, especially over the coastal plain, where fog could linger through mid morning.

Additionally, a separate area of fog and low stratus is expected to form late this evening across the northern Outer Banks and eastern Albemarle Sound as winds remain calm for the first part of the night with high moisture present due to easterly flow there today. This won't be traditional sea fog, however it is expected to cover some marine areas as the air temperatures will be very close to the water temperatures in this area. This area of fog and low stratus is expected to dissipate sometime overnight as winds increase again.

Lastly, a few additional scattered showers or perhaps a rumble of thunder will skirt the Outer Banks overnight as the coastal trough remains just offshore.

Short Term - 6am Monday Morning Through 6pm Monday
As of 330pm Sun...Area will be under broadscale swrly flow, bringing warm and humid conditions across the region. Shower activity should remain generally offshore, though a few showers may graze Hatteras Isl from time to time where left a 20 Probability of Precipitation in place. Highs will soar back into the 70s, with some 60s for the beach communities.

Long Term - Monday Night Through Sunday
As of 230am Sunday...The pattern looks to become more unsettled with several opportunities for much needed rainfall though amounts are likely to be light to moderate through the upcoming week. Forecast rainfall amounts of .5 to up to an inch will be possible through Sat which should help with the dangerous fire weather conditions across eastern NC if this rainfall materializes. Temps will run normal to above normal through the period.

The front which crosses the area Monday night could produce a few light showers as it crosses late Monday into Monday night but most areas should remain dry. The front will stall just south of the area Tuesday into Wed. A couple of weak areas of low pressure will move east along the stalled front and bring a threat for rainfall to the area Tuesday into Wednesday with the heaviest amounts expected along the coast. The majority of the rain is forecast to occur on Wed. High pressure will build over the area Wednesday night and Thu with mostly dry conditions. A warm front will lift slowly north across the area Fri into Sat and could produce some light rainfall across the area.

As cool high pressure builds into the area Tuesday temps will be briefly falling to below normal. Temps warm slight to near normal Wednesday then drop back to slightly below normal Thu as high pressure builds in. Temps could warm back to well above normal Sat if southerly flow develops in the wake of the warm frontal passage.

Marine
SHORT TERM /through Mon/... As of 330pm Sun...Chaotic winds in coastal NC as a coastal trough rides up the coast off of the OBX. North of the coastal trough, winds cont E to NE at 10-15 kt, while to the south, winds have shifted southerly and swrly. The coastal trough will lift north across the waters this evening with SW flow ensuing everywhere at 5-15 kt. Have initiated SCA's (Small Craft Advisories) starting as early as Monday afternoon for the srn/ctrl waters as swrly gradient increases winds into the 15-25 kt range, before a strong cold front pushes through Monday night with winds becoming abruptly north and inc to 20-30 kt. Some brief gales possible with the initial surge behind the front.

Long Term - Monday Through Thursday
As of 230am Sunday...A cold front approaches Monday with SW winds 15-20 kt. Winds shift to N and increase to 20-25 kt with gusts to 30 kt late Monday night into Tuesday behind the front. High pressure builds over the waters Tuesday night and Wednesday with northerly winds diminishing to 10-15 kt. The flow should return to the SW around 10 kt Wednesday afternoon, then shift to the NW-N 15-20 kt Wed night into Thu behind the next frontal system. Seas 2-4 ft Monday build to 5-7 ft Monday night into Tue, then subside to 3-5 ft Tuesday night. Seas further subside to 2-4 ft Wednesday before building back to 3-5 ft Wednesday night and Thu with 6 ft seas possible over the outer waters.
