296 FXUS62 KMHX 061404 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 1004 AM EDT Sun Oct 6 2024 .SYNOPSIS... High pressure will build into the area today. Another frontal passage on Monday will bring our next chance for precip to Eastern North Carolina. Swell from distant Hurricane Kirk will also bring marine and coastal impacts through at least mid week. Strong high pressure and noticeably cooler air building into the area by late this week. && .NEAR TERM /TODAY/... As of 10 AM Sunday...Lingering low stratus across portions of the coastal plain will continue to dissipate over the next hour. No changes to the forecast were needed with this update. Previous Discussion...As of 7 AM Sun...A beautiful Sunday is in store as seasonable and dry high pressure continues to build over ENC. Expect highs in the upper 70s to low 80s, with mostly sunny skies (after morning fog and low stratus burn off), and light northeasterly winds. && .SHORT TERM /TONIGHT/... As of 7 AM Sun...Quiet conditions will continue tonight with high pressure still over the area. Expect mostly calm and clear conditions which will allow for good radiational cooling, and have lows dropping into the upper 50s inland and low to mid 60s along the coast. Some patchy fog development will be possible again, especially over the coastal plain. && .LONG TERM /MONDAY THROUGH SATURDAY/... As of 430 AM Sunday...A cold front with limited moisture will push across ENC on Monday followed by high pressure building in Tuesday through the end of the week. TC Milton is expected to pass well south of the area Thursday. Monday and Monday night...A mid-level shortwave and attendant cold front will push across the area Monday afternoon and evening. Model soundings show limited moisture with the system with saturation mainly below 850mb and very dry air above this layer, including in the dendritic growth zone, so do not expect much precipitation with this system and limiting PoPs to slight chance. SW winds ahead of the front will allow temps to warm above normal with highs in the mid 80s inland to around 80 along the coast. CAA ramps up with northerly flow behind the front Monday night with lows dropping into the mid to upper 50s inland to mid 60s along the coast. Tuesday through Saturday...An upper cut-off slow will slowly push eastward across southern Quebec and northern New England through the period with sfc high pressure building in from the northwest bringing seasonably cool temps and comfortable dewpoints in the 40s and 50s. Skies will be most sunny Tuesday and Wednesday but will see a bit more clouds Thursday and TC Milton moves off the FL coast into the western Atlantic well south of the area. At this time, guidance showing most of the precip remaining south of the area but could see a few showers across the southern coastal waters. Expect increasing NE winds as gradients tighten between high pressure across the Mid- Atlantic and the tropical system. Main impacts from the system are expected across the waters and beaches with an increased rip current, large surf and dangerous boating conditions. There may also be a threat of minor coastal flooding with prolonged moderate to strong NE winds including the threat of dune erosion and ocean overwash in vulnerable locations. Temps will be below normal through the period with highs in the low to mid 70s most days, though increased clouds and stronger NE winds expected to keep temps in the upper 60s to around 70 on Thursday. Lows will generally be in the upper 40s to lower 50s inland upper 50s and lower 60s closer to the coast. && .AVIATION /14Z SUNDAY THROUGH THURSDAY/... SHORT TERM /Through Monday Morning/... As of 7 AM Sun...Widespread LIFR fog and stratus has developed across northern NC, while areas to the south have remained VFR or MVFR. LIFR conditions will continue generally north of US 264 for the next couple of hours before dissipating (including KPGV), while areas just to the south of this could see some brief periods of IFR conditions this morning before clouds and fog begin to dissipate after sunrise (including KISO). By mid morning VFR conditions will return through the rest of the day and into tonight with light winds and mostly clear skies. Overnight, there may again be fog development, though right now it appears to be more patchy and less widespread. LONG TERM /Monday through Thursday/... As of 5 AM Sunday...Mainly VFR conditions expected Monday but a cold front with limited will push across rtes Monday afternoon and evening that could bring isolated showers and perhaps brief MVFR conditions. High pressure with a much drier airmass builds into the area Tuesday through Thursday with VFR conditions prevailing. && .MARINE... SHORT TERM /Through Tonight/... As of 7 AM Sun...Subpar boating conditions expected through tonight as long period swell from distant Hurricane Kirk keep swells at 4-6 ft. SCAs continue for all the waters south of Oregon Inlet where there is high confidence of 6 foot seas persisting through tonight. Winds will be NNE at 10-15 kts through this evening, and then become light and variable overnight. LONG TERM /Monday through Thursday/... As of 530 AM Monday...A cold front will approach the waters Monday with SW winds around 5-10 kt expected ahead of the front. The front will push across the waters Monday evening with winds becoming north to northeast around 10-20 kt late Monday night into Wednesday as high pressure builds in from the northwest. Long periods swells from distant Hurricane Kirk will peak Monday with seas around 4-6 ft with a dominant period around 15-16 seconds on Monday and 3-5 ft with a 13-14 second swell on Tuesday. TC Milton is expected to push across the FL peninsula on Wednesday then pass south of the waters on Thursday bringing tightening pressure gradients and building seas across the waters. Currently guidance showing strong SCA to low end Gale/Tropical Storm conditions (mainly in gusts) Wednesday night into Friday with seas building to 6-10 ft. && .TIDES/COASTAL FLOODING... As of 3 AM Sun...Long period swell arriving from distant Hurricane Kirk will bring an increased risk for elevated rip currents, dangerous surf, and ocean overwash especially across the more vulnerable areas and areas where the dunes have been compromised along the Outer Banks and Crystal Coast. These swell will begin to impact the beaches today and peak on Monday before gradually fading Tuesday into Wednesday. TC Milton is expected to pass well south of the area on Thursday large swell from this system will likely impact the beaches for the latter half of the week. Prolonged moderate NE winds through the week will increase Thursday as gradients tighten between high pressure centered northwest of the area and TC Milton which could also bring a threat of minor sound-side flooding across the southern portions of the Pamlico Sound, Neuse River and eastern Carteret County. && .MHX WATCHES/WARNINGS/ADVISORIES...
