The episode as NWS RAH wrote it up.
Multiple outflow boundaries triggered scattered thunderstorms across central North Carolina during the afternoon and evening resulting in a few pulse severe storms.
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 Raleigh, NC wrote its last area forecast discussion before the first event at Jun 30, 2:15 PM EST, 15 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Raleigh NC 315 PM EDT Tue Jun 30 2020 .SYNOPSIS... An upper level disturbance will track southeastward over North Carolina this evening. A weak surface trough will remain in place over central North Carolina this afternoon and tonight, then drift into the Coastal Plain Wednesday. Drier conditions with higher pressure will arrive Thursday and Friday. && .NEAR TERM /THROUGH TONIGHT/... As of 315 PM Tuesday... A few pulse severe storms are possible, mainly along the NW to SE corridor from Burlington to the Triangle to Rocky Mount south and east to Fayetteville and Goldsboro through mid-evening. Isolated strong storms are possible throughout central NC. A belt of mid and high level cloudiness has been extensive from the southern Appalachians ESE across the western Piedmont of NC this into the afternoon now. This band of cloudiness has been thinning somewhat since early afternoon, but was remaining in place. This has greatly limited instability and convection over the southwestern Piedmont into the Triad region thus far. The storms over the Blue Ridge Foothills of VA and northwest NC are building south and southwest toward the most unstable air. This would put this development on the west side of the Yadkin River (west of the Triad region through late day). Robust scattered thunderstorms were developing along the surface trough located over the eastern Piedmont and Coastal Plain. This region has heated nicely into the mid to upper 80s, with dew points in the lower to mid 70s. Corresponding MLCapes were on the order of 1500 to 2000 J/kg in a tongue from FAY to RDU to near RWI. There was fairly good ThetaE advection with surface moisture convergence along the residual and new outflow boundaries. A few of these storms may pulse to low end severe limits (near 60 mph wind gusts and 1 inch hail potential) through early evening as they work on outflow boundaries. The other threat will be locally heavy rain as the PW's have come up into the 1.7-2.0 inch range with a weak steering flow. Therefore, locally heavy rain of 2+ inches per hour will occur. Most areas should see the heaviest rain fall in 20 to 30 minutes limiting the flood threat to minor. The severe threat continues to be marginal limited by weak winds aloft. Therefore, a few pulse severe storms are possible that are typical of late June in NC. The storms will weaken and become more isolated by mid to late evening and overnight. && .SHORT TERM /WEDNESDAY AND WEDNESDAY NIGHT/... As of 315 PM Tuesday... Models continue to suggest more limited chances of PM thunderstorms on Wednesday. A surface trough will push east into the far eastern Piedmont and Coastal Plain by early to mid afternoon. This should become the main focus for scattered thunderstorms. SPC has removed the marginal risk for severe for the Day 2 outlook. However, isolated pulse storms may again become strong - but likely remaining just below the wind gust criteria. The higher POP (30-40 percent) will be in the east, with lower POP (around 20-25 percent) in the west. Highs again should be in the upper 80s to lower 90s. Lows in the upper 60s to lower 70s. && .LONG TERM /THURSDAY THROUGH MONDAY/... As of 345 AM Tuesday... Thursday and Thursday night: The mid/upper level low, which has parked it's self across the northeast U.S. and New England for the past several days, is finally forecast to shift east-southeastward and offshore Thursday. The trailing mid/upper level trough axis will shift to the east of our area as well. This should result in drier conditions on Thursday, with possibly a few isolated to widely scattered showers/storm, mainly during the afternoon/evening (best chance across the southeast/east). High temps on Thursday are expected to be in the upper 80s to lower 90s, with lows in the upper 60s to lower 70s Thursday night. Mostly dry weather is expected to continue on Friday through Saturday morning in the wake of the departing trough. However, additional s/w energy in renewed northwesterly mid level flow may result in a return to isolated to scattered showers/storms for the rest of the weekend, with the best chance of afternoon/evening storms on Sunday. High temps on Saturday are expected to be in the lower to mid 90s, withs highs a category cooler on Sunday (thanks to increasing chances of showers and storms and resultant cloud cover). Low temps this weekend are expected to be in the lower 70s, with a few mid 70s possible in the southeast. Early next week a mid/upper level disturbance is expected to lift northeastward from the Deep South and into the Carolinas. Moisture and lift associated with this system appears to remain to the south and west of the area through Monday. However, we should see a continued threat of mostly diurnal isolated to scattered showers and storms with highs expected to be in the upper 80s to around 90. && .AVIATION /18Z TUESDAY THROUGH SATURDAY/... As of 100 PM Tuesday... Generally VFR CIGS will dominate central NC this afternoon and tonight. However, scattered showers and thunderstorms with MVFR CIGS and VSBYS are expected. The highest probability of thunderstorms will be at KINT and KFAY, with lesser chances at KRWI. Then later tonight, some patchy sub-VFR stratus and even some ground fog are possible, especially around KRWI. Looking beyond 18z Wed, generally VFR conditions are expected with the exception of a chance of PM showers and thunderstorms. The highest probabilities of a storm will be at KFAY. As drier air pushes in from the north Wed night, shower/storm chances will trend down and be lower than usual Thu and Fri. Generally VFR conditions expected. && .RAH WATCHES/WARNINGS/ADVISORIES...
