952 FXUS62 KMHX 291101 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 701 AM EDT Fri Aug 29 2025 .SYNOPSIS... High pressure will remain in control across the Southeast into early next week. A weak coastal trough is forecast to develop late this weekend into early next week while at the same time, a weak low pressure system may develop well offshore the Southeast coast early next week as well. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... As of 7 AM Fri...Another beautiful day is in store with low humidity, plenty of sunshine and near normal temperatures. A large scale upper level trough will slide eastward today with some subtle height rises expected across Eastern NC. Weak subsidence and an abundance of dry air through most levels of the atmosphere will keep conditions dry, with only a few clouds expected. Low level thicknesses rise slightly, which should allow highs to reach the low to mid 80s across the area under full sun. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/... As of 2 AM Fri...Quiet conditions are expected again tonight with little change in the weather pattern. High pressure just offshore should allow for winds to decouple inland, and with skies remaining clear, strong radiational cooling is possible with lows dropping into the upper 50s to low 60s inland, and mid to upper 60s along the coast. && .LONG TERM /SATURDAY THROUGH THURSDAY/... As of 215 AM Fri... Key Messages - Below normal temperatures expected through midweek next week - Low pressure will remain well off the coast early next week resulting in limited impacts across ENC. More of a fall like pattern across the Eastern Seaboard over the next several days as upper level troughing will remain over the East Coast inviting below avg temps and dry weather for the most part across ENC. We will be monitoring the potential for a slightly more active pattern later next week but as discussed in previous updates, uncertainty in the forecast beyond the next 2-3 days is above average. Saturday through Tuesday...In the upper levels, will have an upper level low situated across the Northeast on Sat which will gradually push into the Canadian Maritimes by early next week while broad upper troughing remains over the Eastern Seaboard. Southern Stream Jet Stream will strengthen slightly as a shortwave traverses the Deep South and Gulf Coast while at the same time a shortwave will push into the Mid-Atlantic allowing the broad troughing over the Eastern Seaboard to deepen slightly Sunday night into Monday. Current guidance suggests an upper level low will then cut off from this troughing Mon night into Tue, though guidance vary where this occurs with the GFS being the outlier, with this low centered across the Mid-Atlantic while the ECWMF and Canadian guidance and ensembles have this low noted further north in the Northeast. At the surface will have a weakening cold front pushing across the Carolinas and quickly dissipating into a coastal trough on Sunday while cool high pressure over the Ohio River Valley oozes south and east into the Mid-Atlantic and Northeast. Coastal trough will remain in place through Tuesday while high pressure remains entrenched across the Eastern CONUS. Low pressure may develop well to the south and east of ENC early next week as well along a baroclinic zone but trends have continued to suggest this low will remain well offshore and offer little in the way of impacts to the CWA. This will keep things generally dry across ENC outside of some isolated shower activity along the aforementioned front on Sat and then some isolate to widely scattered showers and tstms noted along the immediate coast and OBX in association with the coastal trough Sun/Mon/Tue. On Tue will have a stronger and deeper trough and associated mid level shortwave diving SE`wards from the Canadian Prairies into the Northern Plains and this trough will be the next potential weather maker later this week. Temps will continue to remain slightly below avg through Tue with highs reaching the low to mid 80s inland and mid to upper 70s along the OBX. Wed through end of next week... Broad troughing remains overhead with the aforementioned deepening upper trough in the Northern Plains continuing to push south and east into the end of the week. Uncertainty in the overall evolution of this pattern remains high as guidance remains rather spread on the strength and timing of this trough. At the surface high pressure ridging pushes east and a cold front approaches from the west. As this occurs precip chances are forecast to increase from Wed onwards into the end of the week. Though will note given the high uncertainty in the forecast this will likely change in the coming days. Temps remain below avg through the end of the period with upper troughing remaining overhead. && .AVIATION /12Z FRIDAY THROUGH TUESDAY/... SHORT TERM /through Saturday Morning/... As of 7 AM Fri...VFR conditions are expected through Saturday as dry high pressure remains over the region. High clouds over the coast this morning will soon push offshore, and skies will then remain mostly clear through tomorrow morning. Despite strong radiational cooling tonight, fog development is not expected due to an abundance of low level dry air. LONG TERM /Saturday through Tuesday/... As of 215 AM Fri...Primarily VFR conditions are forecast through the long term period with low to very low chances of sub-VFR conditions within any shower or tstm that develop Sat afternoon and on the afternoon and evenings from Sun onwards as precip chances remain limited at best with high pressure in control of the weather pattern. Winds continue to remain light and eventually become NE`rly this weekend. && .MARINE... SHORT TERM /through Tonight/... As of 7 AM Fri...Great boating conditions will continue into this weekend with high pressure sliding offshore today. Winds will be NW/NNW at 10-15 kts this morning, and then become light and variable early this afternoon before coming around to the SSW at 5-10 kts. SW winds continue tonight at 5-15 kts. Seas will be mostly 1-3 ft through the period. LONG TERM /Saturday through Tuesday/... As of 215 AM Fri... We start the period out under benign boating conditions with light and variable winds and 1-2 ft seas noted across our waters Sat morning. A weak cold front will then track across ENC and likely dissipate into a coastal trough Sat night with this coastal trough then moving little into next week. This will allow winds to become NE`rly at 10-15 kts by Sat evening across all our waters with these winds persisting into Sun afternoon. Seas along our coastal waters build slightly to 1-3 ft during this timeframe. Winds then increase further Sun afternoon and evening to 15-20 kts with a few gusts up near 25 kts at times as high pressure building in from the north and west interacts with the aforementioned coastal trough tightening the pressure gradient across the area slightly. These elevated NE`rly winds then continue through Tuesday as incoming high pressure system moves little. Seas across our coastal waters then gradually build through Sun night to 4-6 ft and remain at these heights into Tue thus bringing a low end threat for some SCA conditions starting on Mon. With a coastal trough moving little from SUn onwards could see daily chances for showers and tstms across our coastal waters as well though activity would be isolated to widely scattered in nature. && .MHX WATCHES/WARNINGS/ADVISORIES...
