The episode as NWS RAH wrote it up.
Two rounds of severe weather moved through central NC on the 27th of May tied to a deep upper-level low pressure system over the Mid-Mississippi and Ohio Valleys and an approaching cold front from the Tennessee Valley. The first round of storms was focused along a low-level moisture transport axis in the morning, producing strong straight line winds across the northern half of central North Carolina, along with flash flooding concerns over the western Piedmont and urban areas in the northeast Piedmont. The second round of storms formed along a pre-frontal convergence axis in the afternoon and early evening, stretching from Granville to Scotland County. A cluster of storms organized into a storm complex, which produced local flooding over the Sandhills into southern Wake County and a strong mesocyclone over the Raleigh metro area.
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 27, 1:25 AM EST, 49 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Raleigh NC 225 AM EDT Fri May 27 2022 .SYNOPSIS... A warm front and increasingly humid air will retreat north across the southern Mid Atlantic this morning. A pre-frontal trough will then become quasi-stationary over the Piedmont today, followed by the passage of a cold front across the region tonight. High pressure, and associated much drier and warm conditions, will build across the region this weekend. && .NEAR TERM /THROUGH TONIGHT/... As of 900 PM Thursday... 00Z surface analysis continued to show the wedge front over the n-nw Piedmont, shifting a little north since this afternoon but still invof Forsyth Co. Satellite imagery shows the deep moisture plume ahead of the upper low centered over western NC with some embedded disturbances, the most notable an MCV over s-c GA. Earlier discreet, shallow supercells in the Foothills have more or less coalesced into a broken line of storms with periodic rotation. The line is inching eastward as the storms move n-ne and will flirt with western Forsyth over the next couple of hours. The line extends back to CLT, and while not as vigorous there, there has been renewed development aided by sely flow and an axis of 500-1000 MLCAPE extending from CHS to CLT. Sfc winds are still backed to sely and the low-level flow will be supportive of some rotation in storms, though the overall intensity of the storms should wane some with loss of heating. Will also have to monitor the eastward progression of the line, as it would favor training of storms over the Winston- Salem area if it does push east. Severe Thunderstorm Watch 275 expires at 10pm and we do not expect any need for extension overnight. There should be a lull in convection between 11pm and 4-5am, afterwhich high res guidance suggests another round of storms moving into the southern Piedmont, likely supported by the upstream MCV and weak destablization that generally continues over the western Piedmont. Point soundings in the western Piedmont erode a weak cap by 5am and maintain enough hodograph curvature to warrant at least a low end threat of an isolated severe storm or tornado., particularly as the LLJ is forecast to intensify to ~40kt overhead. However, confidence is low given the unfavorable diurnal timing. Outside of the convective threat, no changes were really made to the forecast other than adjustments to observations in cloud cover, with less cloud cover in the east. lows will remain mild in the upper 60s to mid 70s. && .SHORT TERM /SATURDAY AND SATURDAY NIGHT/... As of 210 AM Friday... The upper trough will progress through the region Sat, with the sub- tropical ridge shifting eastward into the region Sat night. At the surface, the cold front/surface trough will sit over the Coastal Plain Sat, then continue eastward to along the NC coast Sat night, with relatively cool high pressure settling over the Appalachians and into the mid-Atlantic through Sat night. Some showers and storms are possible along the lingering front/trough Sat, but should largely be east of central NC. Otherwise, dry weather is expected across the area through Sat night. Highs in the low to mid 80s, with lows in the upper 50s NW to mid 60s SE expected. && .LONG TERM /SUNDAY THROUGH THURSDAY/... As of 225 AM Friday... The sub-tropical ridge will remain over the Southeast and mid- Atlantic through mid-week, with the center of the high generally over the OH Valley/northern mid-Atlantic. An area of low pressure off the Southeast US coast Mon/Tue, should move westward and inland over the Southeast by mid week. While rain cannot be completely ruled out, the high just to the north should keep it suppressed to the south. High pressure will dominate at the surface Mon, with a Piedmont trough possible Tue and Wed. A northern stream wave will move through the northern Plains and upper MS Valley through Wed and into the Great Lakes/OH Valley Wed night/Thu, pushing the ridge south and east. The best chance for rain in the extended forecast will be with this wave and associated cold front and pre-frontal trough, as they move into the mid-Atlantic/Northeast US Thu/Thu night. Temperatures will remain above average, gradually moderating with time, through at least mid-week. && .AVIATION /06Z FRIDAY THROUGH TUESDAY/... As of 220 AM Friday... Occasionally gusty sly low level flow will transport increasingly moist and humid air across cntl NC this morning. This regime will favor both widespread IFR to MVFR ceilings this morning and also the development and maintenance of multiple bands of showers and storms ahead of a cold front and following drier and more stable air that will not move east across the region until tonight. Outlook: Warm and dry high pressure, and associated VFR conditions, will extend across the region this weekend through early next week. && .RAH WATCHES/WARNINGS/ADVISORIES...
