The episode as NWS ILM wrote it up.
Very deep moisture stayed in place following Tropical Storm Debby. The area was very flood-prone and scattered slow moving storms led to localized flooding especially since a front was stalled in the area.

NWS Wilmington, NC wrote its last area forecast discussion before the first event at Aug 10, 2:57 PM EST, 3 hours 39 minutes earlier.
Area Forecast Discussion National Weather Service Wilmington NC 357 PM EDT Sat Aug 10 2024 .SYNOPSIS... Periods of unsettled weather are expected to continue this weekend and into early next week as a stalled front settles near the area, especially areas east of I-95. With saturated grounds across the region, it will not take much rainfall to cause additional flash flooding. Somewhat drier and slightly cooler weather is expected behind the cold front during the middle of next week. && .NEAR TERM /THROUGH SUNDAY/... Frontal boundary nearly stalled just west of the area. It is progged to recede northwestward overnight and then sink back to its original current location Sunday morning and then drift a bit closer to the coast by midday or afternoon. This afternoon's convection will wane with the loss of heating. Winds light and variable to calm tonight so conditions could favor fog development. Areas that receive appreciable rain will have better chances, but since this is not yet known have just introduced area-wide. The proximity of the front will keep Sunday from growing as warm as today but hefty CAPE will develop once again leading to fairly widespread thunderstorm coverage. With storm motion being capped at 10kt or less the threat for flooding downpours will persist. && .SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/... A stalled frontal boundary will continue to bring unsettled weather to the area through Monday night. Daytime highs around 90. Heavy rain in previous days means that any additional rainfall could easily produce localized flooding. Areas east of I-95 will have the best chance of afternoon showers and storms. These storms will be slow moving and some could train over the area which would produce heavy rainfall accumulations. && .LONG TERM /TUESDAY THROUGH SATURDAY/... Showers and storms expected on Tuesday as the cold front begins to slip southward. A lifting upper level trough will cause the boundary to pivot during the afternoon as the focus for showers and storms shifts to northeastern SC and coastal southeast NC. A stronger trough will dive southward on Wednesday and push the remainder of the cold front offshore. Some residual showers and storms are possible on Wednesday afternoon, but this will be the start of a cooler and drier period. High pressure settles over the region for late next week and into next weekend. Daily highs in the mid and upper 80s with overnight lows in the mid 60s. Dew points in the mid 60s will be a very welcome change as we continue to dry-out after Debby. We will be watching the tropics late next week as what is likely to become Ernesto approaches the western Atlantic. The aforementioned trough is forecast to keep Ernesto out to sea, but local surf and rip current impacts are certainly possible as swells arrive by next weekend. The combination of swells and nice weather will certainly be something to consider for beach safety in the coming days. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... With numerous outflow boundaries it will be difficult to pinpoint convection this afternoon, though the LBT area still stands to see the best coverage. As with previous days VSBY restrictions will generally be MVFR for tempo groups, though very short-lived dips below 1SM will be possible due to our precipitable water values near all time highs for the date. MVFR cigs move in from the NW again overnight and some MVFR fog could develop area-wide especially wherever it rains. Some guidance shows LIFR fog but the probabilistic guidance was a bit too low to forecast such restrictions at this time. Extended Outlook... Predominant VFR expected this weekend into early next week as we return to a more typical summertime pattern with diurnal showers/storms. && .MARINE... Through Saturday... Wind to remain out of the southwest through the period as the waters remain between a frontal boundary and high pressure offshore. The boundary will show a little movement but not enough to affect wind direction. As it draws closer to the coast on Sunday though it will lead to a decrease in speeds. Spectral wave plots show quite a few wind chops that will tend to decrease tomorrow, the greatest power peak being around 8 seconds. Saturday Night through Thursday Night... An approaching cold front will lead to an increase in the potential for showers and storms through early next week. A weak frontal boundary stalled near the coast will keep winds fairly light (generally around 10-15 knots this weekend and around 10 knots early next week). High pressure will sink southward on Wednesday which should bring northerly winds to the area during the middle of next week with cooler and drier conditions. && .ILM WATCHES/WARNINGS/ADVISORIES...
