A boundary observed on radar late that morning was the focus for initial convective development around early afternoon across Harnett and western Johnston Counties. A mid level inversion capped the atmosphere initially across the western and northern Piedmont but this cap was broken around sunset, permitting isolated severe thunderstorms to develop between the Triad and the Triangle regions.

NWS Raleigh, NC wrote its last area forecast discussion before the first event at Jun 24, 12:25 PM EST, 45 minutes earlier.
Area Forecast Discussion National Weather Service Raleigh NC 125 PM EDT Sun Jun 24 2018 .SYNOPSIS... A weak cold front will drop south into the area tonight and will briefly stall across southern portions of the state on Monday before pushing south of the area early Tuesday. && NEAR TERM /THROUGH TONIGHT/... As of 1030 AM Sunday... Main adjustment to the near term forecast was to up PoPs across the Coastal Plain in anticipation of greater coverage/concentration of afternoon convection. 12Z upper air analysis depicts a subtle reflection of a weak trough over the NC Coastal Plain, noted at 850mb, 700mb, and 500mb. This trough should sharpen a bit by afternoon as a weak shear axis, noted on the RAP and the water vapor imagery crossing the northern mountains at 13Z, passes overhead. Strong heating of the moderately moist atmosphere will yield a moderately unstable air mass with MLCAPE projected 2000-2400 J/kg. Area sounding data depicts a decent mid level cap between 650-600mb on the GSO sounding. This feature will likely inhibit convective development over the western Piedmont, plus this region will likely experience some subsidence behind the exiting mid level shear axis by mid-late afternoon. A similar mid level inversion noted on the MHX sounding but is much weaker/shallower. Since the atmosphere in this part of the state is less capped, convection will have an easier time to initiate/develop compared to locations farther west. Cannot rule out an isolated strong/severe storm or tow this afternoon, primarily across the Coastal Plain. however, the bulk effective shear is a solid 5-10 kts lower than the past few days, so expect convective nature to be pulse-type, with strong/locally damaging wind gusts associated with microbursts. Current temperature trend verifying well. Thus, forecast highs in track to reach the low-mid 90s with a few upper 90s probable in the Sandhills. GSO sounding depicts a decent layer of dry air aloft. Mixing of this drier air to the sfc is probable, resulting in sfc dewpoints in the mid-upper 60s. This mixing should also occur in the Sandhills, resulting in dewpoints in the upper 60s/around 70. This should yield heat indices in the 100-105 degree range across the southeast half of the forecast region, with the hottest indices over the Sandhills and southern Coastal Plain. Tonight, the bulk of the convection over the Coastal Plain and Sandhills will dissipate with loss of heating, though the presence of the weak shear axis may allow a few showers/storms to persist across the far south-southeast until midnight or a little after. && .SHORT TERM /MONDAY AND MONDAY NIGHT/... As of 424 AM Sunday... With current upstream satellite and radar trends showing a very perturbed flow pattern over the central CONUS, confidence is starting to increase that central NC will likely have to contend with some sorta convective complex and/or MCV crossing the southern Appalachians and tracking east invof the stalled frontal zone progged to lie across southern NC/upstate SC Monday-Monday night. If timing of such a feature coincides with peak diurnal heating, an organized convective threat could evolve along and south of the boundary in place across central and southern portions of the area. Enhanced shear pocket of 30 to 40 kts, attendant to the vort disturbance, will be more than sufficient to support a damaging wind and hail threat. Additionally, with low-level shear/helicity enhanced invof of the frontal zone, an isolated tornado will also be possible. Will introduce a severe threat in the HWO for Monday across central and southern portions of the area. Highs Monday ranging from mid/upper 80s north to lower/mid 90s south. We will begin to cool off Monday night as high to our north begins to push south. Lows ranging from mid 60s north to lower 70s south. && .LONG TERM /TUESDAY THROUGH SATURDAY/... As of 340 AM Sunday... The lingering surface front will be stalled to the south of the area to start the period on Tuesday, with any lingering associated chances for showers and storms confined to far southern portions of the area. Meanwhile, with cooler high pressure extending into the area expect high temps on Tuesday will be in the mid to upper 80s, with lows Tuesday night in the upper 60s to lower 70s. Isolated to widely scattered (mainly) afternoon/evening showers and storms will be possible for the remainder of the medium range. A passing disturbance to the north will bring a weak surface trough into the area on Wednesday night into Thursday, with a strong mid/upper level ridge extending eastward and eventually southward into our area late week into the weekend. This will result in a return to hot temps and high heat index values during this time frame. However, a lingering weak mid/upper level trough near the coast may help keep highs temps down some across our far east/southeast late week into the weekend, along with perhaps a little better chance for convection. High temps are expected to range from the upper 80s to lower 90s on Wednesday to generally the mid to upper 90s by Friday, and possibly Saturday. Low temps will be in the 70s. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... As of 125 PM Sunday... VFR parameters will persist across central NC through mid day Monday with the exception where scattered convection occurs this afternoon through this evening. In the vicinity of where the heavier showers and storms occur, expect brief instances of MVFR/IFR visibility and MVFR ceilings, along with sfc wind gusts 30-40kts. The convective threat appears highest in the vicinity of KFAY, and just south of KRDU and KRWI. The convective threat will begin to dwindle after 01Z Monday. Overnight into early Monday morning expect VFR conditions though pockets of MVFR fog may be present where the heavier downpours occur this afternoon/evening. A greater threat for scattered convection appears likely Monday into Monday night as an upper disturbance dives sewd across our region during prime heating. This system has the potential to trigger scattered strong-severe storms with wind gusts 40-55kts possible along with some hail. This convective threat appears greatest in the 20Z Monday-04Z Tuesday time frame, with scattered, weaker convection possible late Monday night into Tuesday morning, especially in vicinity of KFAY. Convection should be less numerous from mid week and beyond as an area of high pressure strengthens just north of our region. The presence of this system should inhibit afternoon convective development, especially across the northern counties, with isolated- scattered convection possible late in the day-early evening across the far south-southeast. Otherwise VFR parameters anticipated for much of the remainder of the week. && .RAH WATCHES/WARNINGS/ADVISORIES...
