Synopsis
High pressure will gradually slide offshore tonight. A mainly dry cold front will push through the area Friday night, then lift back north as a warm front Saturday with a stronger cold front pushing through the area Saturday night. High pressure will build over the area late this weekend into early next week, with another front approaching the area mid week.

Near Term - Until 6am Friday Morning
As of 1010pm Thursday...Little changes needed for the late evening update. High pressure centered along the coast will continue to slide offshore overnight. Temps continue in the 40s this evening with a few colder locals dipping into the upper 30s closer to the coast near the center of the high and where high clouds are thinnest. Beginning to see a light S to SW breeze develop across western sections where pressure gradients are beginning tighten some, not that strong around 3-5 kt but just enough to keep temps from falling further or even warm a few degrees. Guidance showing clouds thinning after midnight but also expect to see press gradients continue to tighten some as a frontal system approaches and light mixing will continue to limit additional cooling.

Short Term - 6am Friday Morning Through 6pm Friday
As of 300pm Thurs...The surface high will continue to move further SE from the coast, while a cold front approaches the region from the west. Clouds will gradually increase and lower throughout the day. Most of the day will be dry with a possible slight chance of showers late in the day along the northern zones; ahead of the frontal boundary. Models have trended drier, therefore reduced Probability of Precipitation and coverage area. Low level thicknesses is supporting highs in the low/mid 60s over the NE to upper 60s near Duplin, and Onslow counties.

Long Term - Friday Night Through Thursday
As of 200pm Thu...Unsettled weather still expected for for Saturday and Saturday night. High pressure will build back over the area late this weekend into early next week. Another cold front will but with limited moisture approach the area mid next week.

Friday night through Saturday night...A backdoor cold front will push south through the area Fri night and early Sat, then lift back north through the area during Sat. Looks like moisture will be limited Fri night into Sat morning so not expecting much precipitation during this time and will keep Probability of Precipitation at a minimum. Better chances for rain western and northern areas Sat afternoon with the retreating front. Probability of Precipitation increase to likely all areas Sat night as the front crosses the area. Could see some thunder Sat night, especially near the coast. Temps Sat will be tricky due to with cloud cover and location of frontal boundary during peak heating. Temps across the southern areas will likely be able to climb in the mid to upper 60s, while temps across the northern forecast area may struggle to break 60 deg.

Sunday through Thursday...Dry weather looks to return late weekend into early next week as the cold front pushes offshore early Sunday followed by high pressure building in from the west Sunday into Tue. Slightly below normal temps expected behind the front with highs 55-60 deg through Monday and lows in the upper 30s to mid 40s. Highs should warm into the low to mid 60s on Tuesday and mid to upper 60s on Wed. A cold front with limited moisture will approach from the west mid week, with next rain chance Wednesday. The models are continuing to trend drier with moisture having a tough time making it east of the mountains. Thanksgiving Day is forecast to be dry and cool with highs 55-60.

Marine
Short Term /through Friday/... As of 1015pm Thursday...High pressure centered over the waters will continue to slide offshore overnight with winds veering to W to SW and increase to around 10-15 kt after midnight. Seas have subsided to 2-4 ft this evening but not expected to drop much further.

SW winds increase Friday morning to around 15-25 knots ahead of cold front with Small Craft Adv conditions starting tomorrow mid-morning and continuing through most of the day for the coastal waters and Pamlico Sound. Seas will also build back to 4-6 ft Friday afternoon.

Long Term /Friday night through Tuesday/... As of 200pm Thu...Winds will be veering and decreasing Fri night as a backdoor cold front moves south through the waters. W winds 15-20 kt ahead of the front will become N/NE around 15 kt overnight behind the front. Seas 4-6 ft in the early Fri evening will subside to 2-4 ft late. Sat the front will drift back north through the waters with NE winds 10-15 kt early veering to S/SW in the afternoon with seas remaining 2-4 ft. Conditions will deteriorate quickly Sat night, as a period of strong SW winds 20-30 kt develop ahead of the front...with the potential for a brief period of gale force gusts. Seas will be building very quickly to 6-10 ft Sat night into early Sun. Winds will shift to NW 15-25 kt behind the front Sun, with large seas gradually subsiding during the afternoon and evening with offshore flow. Monday NW winds 10-15 kt will diminish to 5-10 kt as high pressure builds over the waters, with winds Tuesday become SW in the afternoon. Seas are forecast 2-4 ft.
