What forecasters said that day
The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Newport/Morehead City, NC wrote its last area forecast discussion before this flash flood watch went out at Aug 2, 3:31 PM EDT, 21 minutes earlier.
Area forecast discussion, Aug 2, 3:31 PM EDT, 21 minutes before
Area Forecast Discussion National Weather Service Newport/Morehead City NC 331 PM EDT Mon Aug 2 2021 .SYNOPSIS... A frontal boundary will more or less remain stalled over the area through the rest of the week as several waves of low pressure develop along it. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... As of 1030 AM Monday...Low clouds are hanging tough over the central part of the area, but they will continue to erode away toward midday, with a mix of sun and clouds expected this afternoon. Previous discussion...Upper troughing continues across the eastern CONUS with another embedded shortwave diving into the Mid West. At the surface, a quasi-stationary front will remain stalled off the coast bringing light N to NE flow across the area. Plenty of low level moisture remain in place in the wake of yesterday's convection and seeing widespread low clouds and patchy fog across much of the area early this morning which will burn off mid to late morning. Little upper level forcing and only modest instability will limit convection today but still expect isolated to scattered showers and thunderstorms along the sea breeze this afternoon, generally along the coast with limited activity inland. Not quite as hot today with highs in the mid 80s and heat indices topping out in the upper 80s to lower 90s. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/... As of 345 AM Monday...The upper trough continues to dig into the southern states tonight allowing Gulf moisture to begin to surge along the Southeast coast while the quasi-stationary front offshore begins to back into the area. Generally dry conditions expected during the evening once afternoon storms dissipate but will begin to see precip chances increase after midnight. Guidance has trended slower bringing showers back into the area until late tonight, with several high-res models keeping ENC mainly dry until after 12z Tuesday, and have lowered PoPs overnight. Lows expected around 70 inland to mid 70s coast. && .LONG TERM /TUESDAY THROUGH MONDAY/... As of 230 AM Mon...Deep moisture arrives Tuesday, bringing a very active period and heavy rainfall threat that will last at least through late in the week. Tuesday through Thursday...A very wet three days are on tap for the middle of the week. The unseasonably strong trough over the southern Appalachians remains in place (potentially cutting a low off at its base), ensuring that a deep tropical moisture belt remains over the area. PWAT values of 2-2.5 inches prevail through the period. At the surface, the boundary will generally remain along the coast, with several weak waves riding along it about every 18 to 24 hours, leading to periods of increased rainfall coverage and intensity. The heaviest rainfall is currently expected to fall along and east of the boundary, with 3 day QPF in the neighborhood of 6-8 inches along and south of US Hwy 17, with several inches still expected further inland. Given that much of the area has received around-to-well-above normal precip over the past couple of weeks, there will be a significant flash flooding threat that will require close monitoring midweek. Persistent cloud cover and rainfall will moderate temps through the period, and instability will accordingly be limited, with any severe threat currently seeming secondary to the heavy rainfall threat. Friday through Sunday...Persistent strong trough over the Eastern US will finally lift out of the region Fri, only for another mid-level trough, albeit weaker, to dip through this weekend to extend our period of unsettled weather. Another weak low will form along a lingering coastal boundary Saturday before pushing out Sunday. In terms of QPF, will not expect as much heavy rain compared to earlier in the week, but the additional rainfall will certainly add insult to injury. More zonal pattern begins to emerge Sunday, allowing the wet weather pattern to finally begin breaking down. && .AVIATION /20Z MONDAY THROUGH SATURDAY/... SHORT TERM /Through Tue/... As of 1245 PM Monday...Widespread stratus is grad lifting and expect pred VFR developing next cpl hrs that will cont thru late tonight. There will be some sct shra/isold tsra around thru early evening with best potential closer to cst and will add tempo mention at EWN and OAJ. Late tonight deeper moisture begins to spread in with shra grad becoming numerous thru Tue morn that will cont rest of the day. As precip increases expect pred MVFR to develop with poss IFR at times in heavier shra and poss tsra. LONG TERM /Tuesday night through Friday/... As of 245 AM Mon...An extended period of very active weather thru Thursday. Ample low level moisture and periods of heavy rainfall will likely bring prolonged visibility and ceiling restrictions at all terminals, with the greatest confidence closer to the coast (EWN and OAJ). Conditions possibly improve Fri, though some vis and ceiling restrictions may linger. && .MARINE... SHORT TERM /through Tuesday afternoon /... As of 330 PM Monday...A quasi- stationary front will slowly back toward the area tonight. As this happens northeast winds tonight will slowly veer toward the south by Tuesday afternoon, especially over the southern waters. Northeast winds remain north of Cape Hatteras. Speeds generally 10 to 15 kts but some gusts around 20 kts possible especially tonight. Seas remain 3 to 4 feet. LONG TERM /Tuesday night through Friday/... As of 250 AM Mon...A quasi- stationary front will remain over or near the coastal waters through the long term period, bringing a prolonged period of heavy rain. Moderate NE flow 10-15 kts expected Tue before the front slowly retrogrades NW Tue night and into Wed, turning winds more SSWrly behind the front. Brief period of SCA possible Tue night into Wed AM with surge of SSWrly winds behind the front. Hi res guidance shows brief period of gusts reaching 25 kts and seas jumping to 4-6ft, with a few 7 ft waves. Prevailing S/SSW flow expected Wed at 15-20 kts and expected to persist through Thu. Seas linger at 3-5ft, though a few 6ft waves remain possible. Marine conditions relax slightly Fri with SSW flow 10-15 kts and seas 3-4ft. && .MHX WATCHES/WARNINGS/ADVISORIES... NC...None.
