The episode as NWS RAH wrote it up.
A line of thunderstorms associated with an MCS moved into Western North Carolina from Tennessee during the overnight hours. One of the thunderstorms became severe and moved into Central North Carolina, producing isolated wind damage in Davidson County.
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 May 28, 1:30 AM EST, 25 minutes earlier.
Area Forecast Discussion National Weather Service Raleigh NC 230 AM EDT Sun May 28 2017 .SYNOPSIS... Several upper level disturbances will combine with a surface trough to bring a chance of thunderstorms through Monday. && .NEAR TERM /THROUGH TONIGHT/... As of 230 AM EDT Sunday... Early this morning... the current cluster of storms continued to produce wind damage as it crossed I-77 from Statesville to near Charlotte. Warnings are possible if these storms do not weaken as they cross the Yadkin River. Additional weak convection was developing east from this cluster along the old outflow over the south half of the Triad. It appears that some of the storms will make it into portions of the Piedmont and Sandhills. We will monitor for possible warnings. Today and Tonight... A slight risk of severe storms again this afternoon and evening. The chance of thunderstorms today will depend on many factors including the current convection and the placement of outflows to begin the day. We should see plenty of clearing and resultant strong heating today allowing for a good recovery. Surface dew points in the mid to upper 60s combined with highs of 85-90 should lead to MLCapes in the 1500 to 2000 J/KG mid to late afternoon. At least scattered thunderstorms should develop this afternoon and linger into the evening. The SPC outlook highlights much of the area in a slight risk. Damaging winds and large hail will be the primary hazards. Highs today should recover into the mid 80s to lower 90s. Lows tonight will continue warmer than average, in the mid to upper 60s with a lingering slight chance overnight given the approaching front from the NW. && ..SHORT TERM /Monday and Monday Night/... As of 230 AM EDT Sunday... Monday and Monday night: A marginal to slight risk of severe storms expected again Monday afternoon and evening, mainly in the eastern counties. A cold front is forecast to push into the region Monday and Monday evening. Timing of the front is in question, but the slower models may be best. However, any convective outflows may be the main thing to watch for additional strong to locally severe storms Monday afternoon and evening. Both the GFS and EC are in reasonable agreement with the placement of the forecast highest instability and suggest that MLCAPE values could again reach the 1500 to 2000 J/kg range, mainly over the Coastal Plain, where heating may be best. Highs should reach the mid to upper 80s with dew points in the upper 60s. This area should also be in the region of strongest shear with 35-40kt of WSW flow expected (0-6 km). The main threats should be large hail and damaging wind gusts. && .LONG TERM /Tuesday through Saturday/... As of 230 PM EDT Saturday... Closed low will move slowly east across SE Canada and NE U.S. through the period. Central NC will find itself near the base of the associated upper trough and accompanying strong belt of westerlies extending south into the region. While there is generally good agreement on the synoptic scale pattern, sensible weather next week will be greatly influenced by the many shortwave disturbances that are forecast to track through the region within the low amplitude west-southwesterly flow aloft between the aforementioned closed low to the north and the subtropical ridge to our south. Additionally, the exact evolution of these disturbances timing/track/magnitude) will likely play a role in the location of a nearby sfc boundary that's forecast to stall across the SE states. Thus, expect pops near to above climo each day, dependent on difficult to time disturbances, with convection likely to exhibit a diurnal trend. Expect seasonable temperatures with highs ranging from lower 80s north to mid/upper 80s south. Lows in the 60s. && .AVIATION /06Z Sunday through Wednesday/... As of 1245 AM EDT Sunday... A chance of showers/thunderstorms will continue through 09z-12z as the new line of storms emerges off the Blue Ridge shortly. Otherwise, generally VFR conditions expected tonight and Sunday morning. There should be additional storms again Sunday afternoon and night, with any TAF site having a 50/50 chance of a period of storms. All told, outside of convection, VFR conditions are expected through the 24 hour TAF period, although there could be patches of MVFR fog in the predawn at locations which do receive rain. Outlook: There be a chance of mainly late day storms Monday through Wednesday as a cold front slowly approaches from the west and potentially stalls over the area. && .RAH WATCHES/WARNINGS/ADVISORIES... None. && SYNOPSIS...Badgett NEAR TERM...Badgett SHORT TERM...Badgett LONG TERM...CBL AVIATION...Badgett/MLM
