The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Wilmington, NC wrote its last area forecast discussion before the first event at Sep 5, 8:35 AM EST, 25 minutes earlier.
Area Forecast Discussion National Weather Service Wilmington NC 935 AM EDT Sun Sep 5 2021 .SYNOPSIS... Humidity increases by Sunday, and temperatures begin to rebound back to near and above normal thresholds by Monday. Rain chances pick up a little bit by the middle of next week due to a couple of cold fronts, but relax towards the end of the week. Hurricane Larry stays at sea, but is likely to bring increased swell to local waters, which will create dangerous rip currents for the area beaches, as well as rough conditions for mariners. && .UPDATE... No changes needed with morning update as previous forecast remains on track for a quiet sunny Sunday. && .NEAR TERM /THROUGH MONDAY/... Latest sfc analysis shows high pressure offshore with a cold front over the Mid-MS Valley. The local area remains under the influence of the high today, leading to another dry and mostly sunny day with an aftn sea breeze developing. Light S winds will allow for slightly warmer temps than yesterday...highs in the upr 80s inland. Continued dry tonight with light SW flow and low temps in the mid/upr 60s. For Mon, aforementioned cold front approaches the Carolinas from the W, but will be weakening in the process and with mid levels still fairly dry will cap PoPs over western areas at 20%. Slightly warmer than Sun with highs around 90. && .SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/... Cold front weakens as it moves through the area Monday night into Tuesday morning. Moisture is lacking here, and don't expect much in the way of rain. Areas along and west of I-95 still have the best chance of rain at this time, though these chances themselves aren't significant by any stretch of the imagination. Front will stall offshore Tuesday, with really no legitimate upper support. A little more moisture gets introduced by Tuesday afternoon, and while it isn't much, it does continue the chance for isolated to scattered showers and storms in the afternoon. This would follow a diurnal pattern, in which whatever convection spawns should die soon after sunset. High temperatures Tuesday linger near 90 inland, with upper 80s more likely closer to the coast. Lows Monday night in the lower 70s, with lows Tuesday night being a degree or two higher. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... The old frontal boundary offshore fizzles out by Wednesday, with another cold front on the way from the Ohio River Valley. Associated upper trough deepens, and introduces much more robust southerly flow at this point. This brings increased buoyancy and with that comes better chances for showers and storms on Wednesday and Thursday. Forecast gets rather fickle from here again, going back to the speed and strength of this potential Gulf low. Guidance generally seems to have backed off on the potency of this low, muting several of its features. This still promotes a more dry forecast going into next weekend. Official forecast, as it pertains to rain chances, doesn't really deviate much from the previous forecast. Kept the dewpoints on the higher side this time around after the frontal passage late next week. Temperatures remain near or just below normal for early-mid September. && .AVIATION /14Z SUNDAY THROUGH THURSDAY/... Persistence forecast for the aviation community with VFR conditions expected through the period. Some areas did report saturated conditions briefly this morning but moisture was seemingly too shallow for br. There may be a little better chance for a bit of MVFR BR Monday morning and will take a closer look at 18 UTC. Extended Outlook...Mainly VFR. Isolated to scattered showers and thunderstorms Tue though Thu could bring brief flight category restrictions. && .MARINE... Through Monday...Sub-SCA conditions continue with weak sfc high pressure centered offshore and a cold front well W of the local area. Light and VRB winds this morning before a decent sea breeze develops this aftn increasing nearshore wind to 10-15 kt. S/SW winds then stay at 10-15 kt through Mon. Seas stagnant at 1-2 ft during this timeframe, which includes a weak 10 sec ESE swell component. Monday Night through Thursday...Southerly flow holds in consistent around 10kts through Wednesday afternoon. A weak cold front is expected to move through Tuesday, but isn't expected to have much of an impact on the wind flow. Seas remain around 1-3ft. By Wednesday afternoon, a stronger cold front approaches the area, increasing SSW winds to around 15kts, before dropping back down to 10kts by Thursday. All eyes are on Hurricane Larry, which will bring swells into the local waters starting late Tuesday night. Should see Small Craft Advisory conditions by Thursday, with waves 20nm offshore around 6ft at 10+ seconds. These swell will also be likely to bring dangerous rip currents to the surf zone. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...None. NC...None.
