| Area Forecast Discussion National Weather Service Newport/Morehead City NC 742am EDT Tuesday September 23 2025 Synopsis High pressure will continue to extend over Eastern NC from the northeast for the next few days with a weak front and coastal troughing offshore. Another low pressure system will move in from the west late week. Near Term - Today As of 7:30am Tuesday... Key Messages - Areas of fog are ongoing across the coastal plain but should dissipate within the next hour or two High pressure continues to reside across ENC with a stationary boundary just offshore. Overnight and early this morning, this boundary supported some offshore thunderstorms and a few light showers along the coast. There will be two potential culprits for additional light showers and isolated thunderstorms today: the seabreeze and the aforementioned stalled offshore front. Neither should produce more than light precip, and all activity should be relegated to areas east of Highway 17. However, given the over performance of showers overnight and early this morning, Probability of Precipitation has been increased but capped at slight chance. Mid-level heigheights will increase today, warming temps by about 5 degrees compared to yesterday. The coastal plain will reach nearly 90 with the beaches maxing out around 80. Short Term - Tonight As of 2:15am Tuesday... Key Messages - Another round of fog possible tonight Although winds are expected to decouple, there will be greater cloud cover compared to this morning. This will keep lows more mild (mid- to upper-60s) and confidence in the development of dense fog a little lower at this time. Long Term - Wednesday Through Monday As of 330am Tue... Key Messages: - Mostly dry on Wednesday - Pattern becomes more unsettled Thursday through the weekend - Monitoring the Southwestern Atlantic for low pressure development early next week Overall model agreement in the large scale upper pattern is good, but the more minute details remain uncertain especially later this weekend into early next week. This in turn will have an impact on the ambient weather across ENC this weekend into early next week and will likely determine what the eventual evolution of any potential low development in the SW'rn Atlantic is. Wednesday and Thurs...Upper ridging will briefly get amplified on Wed across the Southeastern CONUS into the Mid-Atlantic out ahead of an approaching positively tilted trough which will be centered across the Great Lakes SW'wards to the Central Plains. Ridging will slowly push east into the Atlantic on Thurs/Fri as upper troughing tracks east and nears the Eastern Seaboard towards the end of the week. At the surface, high pressure offshore will gradually push further into the Atlantic while low pressure and its associated fronts located in the Plains on Wed tracks NE'wards on Thurs and Fri with this lows associated cold front nearing ENC on Thurs and gradually tracking across ENC on Fri. With the aforementioned cold front so far away on Wed, the area will generally remain dry outside of an isolated seabreeze shower or storm, though kept PoP's below mentionable given subsidence aloft should limit any seabreeze activity. As we get into Thurs, cold front begins to approach from the west and as upper level dynamics increase, forecast calls for increasing shower and thunderstorm chances Thursday afternoon and evening starting a period of unsettled weather for ENC, primarily along the Coastal Plain. Best chances for precipitation look to be west of Hwy 17. With increasing moisture return, instability looks to increase to around 1000 J/kg. With deep layer shear increasing to around 20-25 kts on Thursday can't rule out a stronger storm or two. As the ridge aloft amplifies, low level heigheights increase across ENC sending high temps to nearly 90 across the coastal plain and low-80s at the beaches on Wednesday and Thurs with lows in the low 70s. Friday through Monday Weather is forecast to remain unsettled through this weekend as cold front slowly tracks across the region and stalls offshore promoting elevated shower and thunderstorm chances with best chances still looking to occur on Fri/Sat. Upper trough remains over the Eastern Seaboard through the weekend, with guidance trending towards cutting off the upper trough with an upper low settling in across the Southeast. Guidance still varies on the exact strength and position of this upper low but general trend is for the upper cutoff low to gradually push NE'wards towards the Mid-Atlantic early next week. At the surface, stalled front remains offshore with high pressure building in from the north and west. Across the Southwestern Atlantic, there remains potential for low development near the Bahamas early next week with any low that develops tracking to the north and eventually the northeast. Though ensemble guidance remains rather spread on the exact track and strength with low development next week. So outside of monitoring the situation will leave any mention of low development rather broad in nature. Temps behind the cold font lower into the mid 70s to lower 80s Sat and beyond as heigheights fall with upper troughing overhead. Marine SHORT TERM /through Tuesday/... As of 2:45am Tuesday... Key Messages - Conditions improving as Gabrielle moves farther away Long period swell from Gabrielle continues to impact our coastal waters with latest buoy obs reporting 6 ft seas at 12-14 seconds. Conditions will improve through the day, however, with seas expected to subside to 4-5 ft at 11-12 seconds by tonight. Therefore, the SCA (Small Craft Advisory) in effect for the central waters remains in effect until 8pm tonight. Scattered showers and thunderstorms will be possible across the coastal waters today due to a stalled boundary offshore. Long Term - Wednesday Through Saturday As of 230am Tue...Benign boating conditions are forecast at the start of the long term with S'rly flow at about 5-10 kts expected across all our waters on Wednesday. At the same time seas along the coastal waters will be about 2-4 ft. A weakening cold front will begin to approach from the west on Thursday which will pinch the gradient slightly allowing S'rly winds to increase to 10-20 kts Thurs evening before the gradient relaxes slightly on Fri allowing winds to decrease back down to 10-15 kts. Even with the increase in winds seas will generally remain around 2-4 ft across our coastal waters. Aforementioned cold front slowly moves across ENC and eventually pushes offshore over the weekend increasing shower and thunderstorm chances from Thurs onwards and eventually allowing S'rly flow to shift to a NE'rly direction behind the front at 10-15 kts late this weekend. Seas look to generally remain around 2-4 ft through the remained of the period. Tides / Coastal Flooding As of 345am Tuesday...Long period swell from increasingly distant Gabrielle will continue to reach the coast of ENC over the next 1-2 days. The latest guidance suggests this will be a notable 11-13 second swell, but seas are only forecast to be 3-5 ft. Vulnerable areas outside of dune protection will be susceptible to minor runup during high tide cycles, but with conditions expected to improve today, no headlines have been issued. NOAA Newport/Morehead City NC Office - Watches - Warnings - Advisories NC...Beach Hazards Statement through this evening for NCZ196- 203>205. Marine Small Craft Advisory until 8pm EDT this evening for AMZ152(Oregon Inlet to Cape Hatteras NC)- 154. |
