Area forecast discussion, Aug 30, 2:48 PM EDT, 3 hours 39 minutes before
Area Forecast Discussion National Weather Service Newport/Morehead City NC 248 PM EDT Fri Aug 30 2024 .SYNOPSIS... High pressure will remain centered to the east in the Atlantic through the weekend while multiple fronts impact ENC. The first front will approach the region Friday, bringing increased shower and thunderstorm chances. The front lifts back north on Saturday with a second front approaching the area on Sunday and then moving through on Monday, keeping things unsettled into early next week before high pressure finally builds in from the north. && .NEAR TERM /THROUGH TONIGHT/... As of 245 PM Fri...Convection is evolving as anticipated this afternoon with initiation both along the sea breeze and a stalled cold front sitting roughly from Oregon Inlet to Little Washington. Already seeing weak development in a sufficiently buoyant airmass, but strongest storms are along the coast and the frontal boundary itself where low-level forcing is strongest. Northern activity will gradually drift southward through the day, while along the coast storm motions will be stalled and highly dependent on erratic mesoscale influences (i.e. storm outflow). Wind shear is typically weak but DCAPEs are exceeding 800 J/kg, especially south of the front, along with SBCAPEs at around 3500-4000 J/kg. Combined with PWATs near 2", a few isolated strong storms are possible capable of damaging winds (40-60 mph gusts). Along the sea breeze where storm motions are slower, some minor ponding/flooding issues are possible in urban and vulnerable areas. Rain chances quickly diminish after sunset, but with ample ground moisture from rainfall today, there is a threat for impactful fog for the coastal plain. Lows tonight in the low 70s again inland, mid 70s along the coast. && .SHORT TERM /SATURDAY/... As of 245 PM Fri...Frontal boundary will linger around the area in the morning before lifting northward. Upper level support will not be as strong tomorrow, but with temperatures still well into the 80s and dew points remaining in the 70s there will likely be enough buoyancy to support scattered shower and thunderstorm development. Focus will be primarily along the sea breeze tomorrow, and the forecast follows a typical summer convective pattern with highest PoPs in the afternoon and evening hours. Shear will be weaker than today, and no severe risk is anticipated. && .LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/... As of 4 AM Fri...A period of unsettled weather will occasionally affect ENC through Monday, then a cooler air mass with limited rain chances Tue through mid week. Sunday...Ocnl diurnal/evening showers/storms through this weekend (20-40% chc), as a wavy front lingers across the region. Limited severe chances as effective shear will be 10 kt or less. Temps will be near to slightly above climo, generally 85-90 for highs, and low 70s for lows. Monday...The front finally pushes through on Monday, and brings with it the best chance for widespread showers/storms. Have enough confidence on timing to bump up pops (40-70%), highest srn zones where a sea breeze interacts with the front before it pushes through. Decent QPF amounts of 0.5-1" appear likely, with locally higher amounts in heavier convective cells. Perhaps a better chance for some strong storms as shear inc to 20-30 kt, but CAPE vals will be a bit less (<1500 J/KG) with cooler temps and more widespread cloud cover. Tuesday through Thursday...A much cooler and drier airmass for most of ENC will try to work in behind the aforementioned front, and areas across northern NC will have the best chances of seeing more pleasant and seasonable conditions with mo sunny skies and drier weather. However areas farther south may remain stuck in clouds with perhaps some ocnl rain, though with a brisk nerly wind expected, any precip will be overrunning with limited thunder threat. Highs near 80 for most, with lows in the 60s. Have kept fcst pop-free for nrn 2/3 of the FA, while hanging onto a 20% chc for the srn zones. Highs generally near 80 with lows in the 60s. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... SHORT TERM /Until 18z Sat/... As of 245 PM Fri...Typical convective pattern this afternoon across eastern NC terminals as scattered showers and thunderstorms develop in a moist and buoyant airmass. Storms along the sea breeze will pose a threat primarily to OAJ and EWN, but stronger storms along the front are expected to impact the coastal plain from the northwest early this evening. Environment today is marginally supportive for damaging wind gusts and any stronger storms that impact terminals may bring gusts in excess of 35kt. Guidance signal for fog is fairly strong across the coastal plain tonight, especially for terminals west of EWN, and now explicitly show IFR across these areas early Sat morning. There could be some patchy dense spots with vis under a mile at times. Conditions quickly return to VFR by 15z Saturday. LONG TERM /Sat through Tue/... As of 4 AM Fri...More unsettled conditions are expected through the weekend as a front moves into the region and stalls. This will bring the potential for bouts of sub-VFR conditions but outside of those instances expect VFR conditions to prevail. Monday stands the best chc for more widespread showers/storms, then Tue through midweek will trend dry. && .MARINE... SHORT TERM /through Saturday/... As of 245 PM Friday...Benign conditions persist over area waters this afternoon as a weak cold front sinks southward to roughly Oregon Inlet westward. Outside of spotty convective activity, winds are variable and around 5 kt. Seas offshore sit at 2-3 feet and will persist through the period as the front continues to meander tonight into tomorrow. By tomorrow afternoon, the front is expected to lift back northward with a return of southwesterly winds around 10-15 kt. Seas hold at 2-4 feet into the first half of the weekend. LONG TERM /Sat night through Wed/... As of 4 AM Fri...Good boating conditions are expected through this weekend with Bermuda high pressure reestablishing offshore. By Saturday sswrly flow will return with winds around 5-15 kts with gusts to around 20 kt, and will cont through Sunday. Seas will be mostly 2-3 ft through the period, though some 4 footers may occasionally develop across the outer waters. Monday, cold front expected to return from the north and push through all of ENC late in the day. Tuesday will see gusty nerly gradient winds of 15-25 kt with SCA conditions trending more likely for the coastal waters and Pamlico Sound, perhaps for the remaining sounds and Neuse river as well. Seas will inc to 5-8 ft for the coastal waters for Tue through Wed. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None.
