Area Forecast Discussion National Weather Service Raleigh NC 300 PM EDT Wed Jun 14 2017 .SYNOPSIS... A weak upper level disturbance will drift southeastward across central and eastern North Carolina through this evening. A backdoor cold front will push southward down the Mid-Atlantic coast tonight. This front will settle across North Carolina and weaken during the day Thursday. A moist and unsettled air mass will hold over the area through the upcoming weekend. && .NEAR TERM /THROUGH TONIGHT/... As of 240 PM Wednesday... Scattered slow-moving storms have initiated over the NC foothills and central/southern mountains, as well as near and just south of the NC/SC border where the morning cap has dissipated resulting in moderate instability with MLCAPE over 1000 J/kg. Elsewhere, despite strong heating and temps in the upper 80s to lower 90s with dewpoints in the 65-70 range, convection has been largely suppressed thus far by a lingering weak cap and fairly dry air just aloft, although this CINH has largely weakened or vanished in the last hour or so. We remain in a moist environment (PW approaching 150% of normal), with a weak vorticity max and southeast-moving mid level shortwave trough that will drift over the region through this evening. As the vanishing cap is supplanted by marginal to moderate instability over the next few hours, convection should continue to grow upscale with expanding coverage over central NC for the rest of the afternoon through early evening. The latest convection-allowing models differ regarding storm details, not unsurprising considering the weak mid level flow which will result in meandering, slow- moving, outflow-dominant cells. But in general, the higher coverage is expected to be in the NW CWA through late afternoon, translating into the central/E CWA where instability is apt to be greater. Will hold onto pops peaking at 50-60% chances. The presence of dry air within and just above the mixed layer will bring about a risk of enhanced wind gusts with any storm, however the weak deep layer shear (generally under 20 kts) should greatly curb storm organization and updraft longevity and intensity. PW is elevated but not excessive, however the slow cell movement and proximity regeneration of updrafts leads to some concern for pockets of heavy rainfall totals which, if they occurred over an urban or otherwise flood-prone area, may lead to localized flooding concerns. However, a widespread flooding threat is not expected, given the incipient dry conditions and patchy nature of such storms. Storm coverage and strength should abate by late evening into the overnight hours, so will trend the late-day good-chance to likely pops gradually down to isolated showers by late tonight. Lows in the upper 60s to lower 70s. -GIH && .SHORT TERM /Thursday through Thursday night/... As of 300 PM Wednesday... Confidence in convection details is further reduced as early as tomorrow, as the very weak steering flow combined with the increasingly moist column (PW rising to 1.75-2.0") and surface dewpoints in the upper 60s to lower 70s favors numerous storms with slow, outflow-dominant motions. The backdoor front which slides southward into NC tonight appears to have few consequences, considering the very light surface flow along and either side of it (indicating very small low level mass convergence), the almost nonexistent dewpoint response, and the continued elevated thicknesses (10-15 m above normal) over NC through Thu. What will remain will be just a subtle pressure trough through central NC, with little else in the way of a convective focus. Mid level debris clouds from upstream convection may help to reduce insolation a bit Thu, although this may be minimized by weak subsidence aloft in the wake of today's shortwave trough. But it still appears that we'll see scattered to numerous storms developing in the afternoon (perhaps focusing first on the higher terrain and on the sea breeze), as we achieve moderate instability in conjunction with the high PW. Once again, the risk of large hail and strong winds should be fairly low (although not zero) with the weak deep layer shear and modest mid level lapse rates mostly under 6 C/km, but localized high rainfall totals may result in an urban and stream flooding threat. Convection should again fall off from late evening onward with loss of heating, however the moist column and marginal elevated CAPE overnight may still support isolated showers and a storm or two through the night. Highs 85-92. Lows around 70. -GIH && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... As of 255 PM EDT Wednesday... Persistent subtropical ridging over the Atlantic will amplify and retrogress slowly through the weekend. This will maintain a climatologically warm and moist airmass over the area into the middle of next week. This will not be an environment with strong forcing or strong shear, and details beyond the weekend are particularly low confidence. A stalled frontal zone will lie over the area Friday into Saturday, providing at least modest low level forcing to stimulate/enhance diurnally driven convective activity. As such, ongoing PoPs in the likely (60-70%) range are on track with highs mostly from 85 to 90. The frontal zone becomes more diffuse on Sunday, with weakened forcing to stir up the unstable airmass, so 40-50% PoPs suffice for Sunday with highs again in the 85 to 90 range. A front approaching from the west suffers from questionable timing but looks to be blocked and stalled over the eastern Carolinas later Monday, and could linger across the coastal areas through Tuesday or even Wednesay. Will have 40-ish PoPs area-wide Monday, and tilt the range towards the east for Tuesday and Wednesday just to set the trend pending better/later model consensus. No airmass change and thicknesses exceed 1410 meters each day...still looking like 85 to 90 each day with mesoscale variations due to convection. Min temps through the period will be a broken record as well...upper 60s to lower 70s. && .AVIATION /18Z Wednesday through Monday/... As of 1240 PM Wednesday... Aviation conditions will be mostly favorable, although scattered to numerous storms are anticipated, mainly 19z today through this evening. Passage of a weak upper level trough, strong heating, and a moist atmosphere will help prompt development of storms today, first affecting INT/GSO soon after 19z, then shifting to the E and SE to around RDU by 20z or 21z, then to RWI/FAY near 22z or 23z. Storms will start out isolated to scattered before increasing in coverage late afternoon into early evening. By 21z or 22z, storms may form into clusters that are not be easily circumnavigable. Cigs/vsbys will be mostly VFR today into early tonight, except for a period of MVFR or perhaps briefly IFR cigs/vsbys and erratic strong and gusty winds in and near storms. MVFR fog is possible areawide after 06z. Confidence in MVFR fog is lower than usual, however the risk of worse conditions (such as IFR/LIFR) appears to be very low, with VFR remaining prevalent. Light winds mainly from the W or NW are expected through this afternoon, becoming light/variable under 6 kts this evening/tonight as a weak backdoor front drops into the area from the north. Looking beyond 18z Thu: We'll stay in a wet and unstable pattern with a daily chance of showers and storms, mainly (but not solely) each afternoon and evening, through at least the upcoming weekend. VFR conditions will continue to dominate, however sub-VFR conditions and gusty winds are likely in and near storms. The risk of early morning sub-VFR fog and stratus will be fairly low through Sat morning, but should increase Sun morning and beyond. -GIH && .RAH WATCHES/WARNINGS/ADVISORIES...
