The episode as NWS RAH wrote it up.
Isolated pulse severe storms developed during the late afternoon into early evenings in an environment characterized by a deep dry sub cloud layer with moderate instability, which yielded enhanced destructive downburst winds across portions of the Piedmont of central North Carolina.
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, 2:16 PM EST, 2 hours 7 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Raleigh NC 316 PM EDT Sun Jun 30 2019 .SYNOPSIS... A backdoor cold front will settle south through central NC this evening and tonight. Weak surface high pressure will build briefly over the area on Monday before moving offshore on Tuesday. && .NEAR TERM /THROUGH TONIGHT/... As of 315 PM Sunday... While convection has raced southward this afternoon ahead of the backdoor cold front progged to move into the Carolinas later this evening, the current dewpoints show the actual front is just now entering northern VA and will take a while to come southward. In the meantime, some convection to watch on the radar with one multi-cell cluster moving through the Richmond area at this time and a second back across southwest VA about to push into TN. There is a gap in coverage between these two features and much of central NC may remain in that gap for most of the afternoon as high resolution models split these two features, sending one to the east of the forecast area and the other to the west. That aside, the Piedmont trough remains across the area and could be a focus for some isolated to scattered convection this afternoon. Looking at SPC meso- analysis, very strong low level lapse rates coupled with surface temperatures in the low to upper 90s are helping to destabilize the area. This is resulting in almost 1500 J/KG of ML CAPE across the north and almost the same amount of DCAPE area wide. This will make winds the primary threat with any convection that does occur. At this time SPC has the northern half of the area in a marginal risk for severe weather. Overnight convection will quickly dissipate and during the early morning hours the front will begin to move across central NC filtering in the cooler and drier airmass behind it. No fog or low stratus is expected as a result and temperatures should bottom out in the upper 60s to low 70s. && .SHORT TERM /MONDAY THROUGH MONDAY NIGHT/... As of 315 PM Sunday... A little cooler and drier on Monday as the front moves south of the area but by afternoon strong ridging aloft over the Gulf Coast helps thickness values begin to rebound in the south and west. Expect temperatures to top out highest here with mid 90s expected. The northeastern coastal plain will have the best chance to remain sub- 90 on Monday with mid to upper 80s expected. With subsidence across the area, not much in the way of precipitation expected. Low temperatures mainly in the upper 60s. && .LONG TERM /TUESDAY THROUGH SUNDAY/... As of 212 PM Sunday... ...Triple digit heat expected across portions of central NC by the middle of next week... Little change in forecast thinking from previous cycles. A hot and increasingly humid pattern with climatological daily diurnal rain chances will continue to be forecast through the long term period. Perhaps the day with the greatest shower/tstm coverage and highest rain amounts will be on Thursday thanks to a weak upper disturbance set to cross our area while rotating around the periphery of the upper ridge that will be parked over the SE and Deep South all week. Then over the weekend heights will begin to fall and a weak cold front is progged to slip south, so that may also result in increased rain chances then. Otherwise, typical climo PoPs for afternoon/evening scattered showers/tstm are forecast. The main weather story, however, will continue to the dangerous heat. Given the strength of the aforementioned ridge, coupled with w/sw flow, will set the stage for high temps well above 90 degrees throughout the long-term period, likely peaking on Wednesday with afternoon highs nearing/surpassing 100 degrees along and south of I- 40. Heat index values will also trend into triple digit territory by Wednesday afternoon, likely nearing advisory level criteria (105 degrees) in the 1pm - 6pm time frame. Heat advisory criteria may be reached again in spots south and east of the Triangle on Thursday. Subtle cooling expected over the weekend with increased clouds, precip chances, and frontal passage. For excessive heat information and safety, please visit www.weather.gov/safety.heat && .AVIATION /18Z SUNDAY THROUGH THURSDAY/... As of 142 PM Sunday... 24 hour TAF Period: A back door cold front approaching from the north will be the main weather feature this afternoon and evening. Convection could spark along or ahead of this boundary resulting in isolated to scattered showers and thunderstorms. These will progress from north to south likely affecting the northern terminals between 21z and 00z potentially dissipating before reaching KFAY. Strong wind gusts would be the primary threat with any of these storms. Outside of convection, VFR conditions are expected through the TAF period with little threat for fog or low stratus overnight behind the front. Winds will be a little breezy this afternoon gusting up to 15-20 kts on occasion out of the west northwest. Long term: Conditions are expected to remain VFR through midweek when chances for convection increase during the afternoon and evening hours. && .RAH WATCHES/WARNINGS/ADVISORIES...
