The episode as NWS RAH wrote it up.
Multi-cellular convection developed ahead of an approaching cold front over Central North Carolina. A few thunderstorms became severe during the afternoon and evening, producing scattered wind damage. During the early morning hours of the 20th, the event morphed into more of a heavy rain and flash flooding threat, where isolated flash flooding developed within the convection ahead of the front.

NWS Raleigh, NC wrote its last area forecast discussion before the first event at Jun 19, 1:12 PM EST, 1 hour 25 minutes earlier.
Area Forecast Discussion National Weather Service Raleigh NC 212 PM EDT Mon Jun 19 2017 .SYNOPSIS... A cold front will track east across the mountains this evening, then stall over the Carolinas tonight. The front will gradually dissipate over the region on Tuesday. && .NEAR TERM /Today and Tonight/... As of 200 PM Monday... Overview: A cold front attendant a vertically stacked cyclone in vicinity of Hudson Bay will track east across the southern Appalachians this aft/eve, then stall over central NC tonight. Broad cyclonic flow aloft will develop over the region this afternoon into tonight as an upper level trough over the upper Great Lakes progresses eastward into the OH Valley (this aft/eve) and northern Mid-Atlantic (tonight). Expect an increasing potential for DPVA attendant small amplitude waves as cyclonic flow aloft becomes established this evening/tonight. Environment: An extremely moist airmass is in place across central NC today, with surface dewpoints ranging from 72-75F and 925 mb dewpoints near ~20C (68F). Despite the presence of weak mid-level lapse rates, rich low-level moisture and strong diurnal heating (highs ranging from the mid/upper 80s W/NW to lower 90s E/SE) will yield 1500-2500 J/kg of MLCAPE by peak heating. As of 17Z, CINH had entirely eroded and moderate diurnal destabilization (1500-2000 J/kg MLCAPE) had been achieved over most of central NC. Isolated convection cannot be ruled out anywhere through mid-afternoon in assoc/w mesoscale features such as differential heating boundaries, the seabreeze and/or outflow from convection that develops along the seabreeze. The relative best forcing will not arrive until late this evening/tonight (21-06Z) when the SFC-925 front progresses into the western Piedmont and small amplitude waves /DPVA/ become more likely as cyclonic flow aloft strengthens over the region. Hazardous Weather: Portions of central NC (primarily along/west of Hwy 1) are in a slight risk for severe thunderstorms this afternoon and evening. Strengthening westerly wind shear (25-35 knots by 21- 00Z) suggests multicellular organization will predominate, though transient supercellular organization cannot be ruled out. As activity develops along the front and/or on the eastern slopes of the Appalachians by late afternoon, expect convection to grow upscale via outflow as it progresses across the western Piedmont toward the Hwy 1 corridor. Moderate instability, moderate DCAPE (750- 1000 J/kg), and high PWAT (~2.00") suggest severe downbursts will be possible in association with any deep convection this afternoon and evening, with the greatest potential along/west of Hwy 1 where cold pool consolidation is most likely to occur in vicinity of peak heating. Torrential rainfall can be expected with any deep convection this afternoon through tonight (rainfall rates 1-3" per hour). Isolated flash flooding will be possible in areas repeatedly affected by convection, particularly urban, low-lying, and other flood prone locations. -Vincent && .SHORT TERM /Tuesday and Tuesday night/... As of 200 PM Monday... The cold front progressing into the region late this evening is expected to stall over central NC tonight and persist during the day Tue, amidst broad cyclonic flow aloft and rich moisture (PWAT ~2.00"). With the above in mind, expect numerous showers/storms in vicinity of the stalled front Tue/Tue night, primarily east of Hwy 1 and south of Hwy 64. Little potential for convection is expected north of the front in the far N/NW Piedmont near the VA border where a drier airmass (PWAT ~1.50" and dewpoints in the lower 60s) is progged to be in place during the day Tue. However, even in the northern Piedmont, isold to sct convection will be possible AOA ~00Z as the front washes out and moisture returns N/NW toward the Appalachians. With cloud cover and convection, expect highs in the lower 80s across most of central NC. Lows Tue night should range from the mid 60s far N/NW to lower 70s far S/SE. -Vincent && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... AS OF 100 AM Monday... With the main front expected to stall over eastern NC, there should be enough drying in the atmosphere to suppress convection especially across western and northern sections of NC. The close proximity of the front in the SE supports the continuation of at least a chance of showers and thunderstorms in the south and east Wednesday afternoon into the evening. Temperatures will be a bit cooler again Wednesday, but highs in the mid 80s give or take a few degrees appear on target. Lows in the mid to upper 60s are expected again Wednesday night, with lower 70s in the SE. Deep moisture is expected to return quickly from the south on Thursday as high pressure builds in the western Atlantic, and the return flow around the high will bring the surge of deep subtropical moisture back with dew points again in the 70s. Once the moisture returns, the chance of showers and thunderstorms will increase again with 50-70 POP warranted Thu-Fri. Highs will warm back into the 85- 90 range with lows in the upper 60s to lower 70s both days. Showers and thunderstorms appear to likely continue Friday through Sunday with a very moist flow mid/upper flow, very moist boundary layer, and a cold front (or two) making runs toward the region, likely stalling before pushing deep into central NC. So, a continuation of high POP's, and eventually a flood or flash flood risk may evolve if the current QPF of 2-4 inches materializes into the late week and weekend. && .AVIATION /18Z Monday through Saturday/... As of 130 PM Monday... 24 Hour TAF period: VFR ceilings (3000-4000 ft AGL) were present over most of central NC early this afternoon. S/SW winds sustained at 10-15 mph will gust up to 20-25 mph at times this afternoon and evening. All terminals are expected to be affected by showers and thunderstorms late this aft/eve into tonight as a cold front progresses east of the mountains into the western Piedmont. The overall best chance for showers/storms will fall roughly between 21Z this afternoon and 06Z tonight, though convection could persist into the 06-12Z time frame at eastern terminals. Isolated severe thunderstorms capable of producing WSW wind gusts up to 50 knots will be possible between 21-03Z, primarily at the INT/GSO/RDU terminals. Looking ahead: The aforementioned front is expected to stall over central NC tonight, then gradually wash out during the day Tuesday. Sub-VFR ceilings cannot be ruled out during the pre-dawn /early morning/ hours each day this week. Diurnal convection will be possible both Tue/Wed, though primarily at eastern terminals. Early morning stratus and diurnal convection could potentially affect all terminals Wed-Sat, though confidence is lower than avg. -Vincent && .RAH WATCHES/WARNINGS/ADVISORIES...
