The episode as NWS RAH wrote it up.
As the remnants of tropical cyclone Debby lifted into Pennsylvania, a cold front remained draped across western North Carolina. Anomalous moisture remained across the area, along with antecedent conditions being wet for early August. A scattered line of storms developed across the northwest Piedmont and produced flash flooding in Guilford County. Several reports of flooding occurred in the town of Greensboro.
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 Aug 9, 6:47 PM EST, 2 hours 53 minutes earlier.
Area Forecast Discussion National Weather Service Raleigh NC 747 PM EDT Fri Aug 9 2024 .SYNOPSIS... A surface trough will hold over the Piedmont of North Carolina through Saturday, then slowly move east and southeast through the area Sunday into Monday. && .NEAR TERM /THROUGH TONIGHT/... As of 745 PM Friday... The Flood Watch has been canceled for all areas. Scattered showers/storms have been limited to the north-central and northwest Piedmont late this afternoon and evening. However, heavy rain is no longer anticipated to the east (over the Coastal Plain). Thus, the Watch has been canceled. Look for the scattered storms over the Piedmont to gradually die off by 1000 PM or so. Isolated heavy rainfall is possible until then. Otherwise, mainly clear to partly cloudy skies expected overnight. With a wet ground and light winds, we should see development of low clouds and stratus across the E overnight. Lows in the low-mid 70s. && .SHORT TERM /SATURDAY AND SATURDAY NIGHT/ As of 220 PM Friday... Aloft, as the parent low moves slowly through Ontario and western Quebec, a s/w will swing through the Great Lakes around it, with the attendant trough sharpening and amplifying slightly as it slowly moves eastward through the OH and TN Valley regions. At the surface, a trough will remain in place over central NC through the day and into Sat night as a cold front approaches from the west. A weak low could develop within the trough Sat aft/eve, but exactly where remains a bit unclear. The front should slowly move into the area Sat night. While there could be an isolated/spotty shower Sat morning, expect a relatively dry start to the day. SBCAPE could peak in the 1000-2000 J/Kg range Sat aft, with max 0-6 km bulk shear of 20-30 kts. Showers and storms are expected to develop Sat aft, mainly along the surface trough, then drift eastward through Sat eve. Convective activity should wane with loss of daytime heating, however cannot rule out some redevelopment along/ahead of the front as it moves into the area Sat night. PWATs should still be in the 2.0-2.5 inch range across the southeast half of central NC on Sat, so any showers/storms that do develop will be capable of producing locally heavy rainfall, which could be problematic given the already saturated soils and elevated stream flows. Highs should top out in the upper 80s to low 90s. Lows may be a little tricky as the front moves in, but generally expect temps to range from upper 60s NW to mid 70s SE. && .LONG TERM /SUNDAY THROUGH FRIDAY/... As of 315 PM Friday... As the frontal boundary barely makes any progress from Saturday to Sunday, another day of showers and storms along the southeastern portion of the region is expected. The low over GA is expected to move into southern SC by late evening Sunday but will wafer back and forth until late Tuesday when weak surface high pushes into the Mid- Atlantic region. Scattered showers and storms are expected everywhere Tuesday especially in the afternoon as the front becomes more west to east oriented continuing showers and storms over the region Tuesday. Wednesday surface high builds into the area resulting generally dry weather across the region. A few diurnal summertime afternoon showers and storms are possible in the far southeast Wednesday and Thursday with another system moving into the region Friday through the weekend. Over the long term period high temperatures will bee in the low to mid 80s. A taste of fall on Wednesday as the front clears the region with highs in the low 80s and dewpoints int the low/mid 60s. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... As of 745 PM Friday... Generally VFR conditions are expected through the next 24 hours. However, IFR to LIFR conditions are possible with stratus and fog in the east between 07z and 12z. There is also a chance of thunderstorms with MVFR conditions over the east again Saturday between 20z and 02z. Looking beyond 00z Sunday. Expect generally VFR conditions. However, another chance for sub-VFR fog/cigs E early Sun morning. VFR conditions will dominate for much of the week, with a chance for late-day showers/storms each day. The greatest chance looks to be Tue night into Wed. && .RAH WATCHES/WARNINGS/ADVISORIES... None. && SYNOPSIS...Badgett NEAR TERM...Badgett SHORT TERM...KC LONG TERM...CA AVIATION...Badgett
