The episode as NWS FWD wrote it up.
A broad upper level trough parked over North and Central TX during the 2nd week of August, generating several days of scattered convection. Activity became a bit more organized on the 17th due to the presence of a mesoscale vorticity center. This convection led to flooding and flash flooding over several of our southern and central counties.

NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Aug 17, 6:27 AM CST, 2 hours 58 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Fort Worth TX 727 AM CDT WED AUG 17 2016 .AVIATION... 12 UTC TAF Cycle Concerns---MVFR/IFR ceiling trends through the 12 UTC TAF cycle. Afternoon convective potential. Metroplex TAF Sites---A tight gradient in ceilings exists across the Metroplex TAF sites this morning with the southern and eastern most sites (GKY and DAL) noting brief periods of IFR ceilings. Satellite imagery suggested that perhaps drier air aloft was pushing southward beneath convective anvil which may be the limiting factor for a more sustained IFR ceiling event across the Metroplex. For now, I have cautiously removed IFR ceilings from all sites except GKY where better moisture may be in place. Convection on area radars continues to blossom this morning across Central TX ahead of a Mesoscale Convective Vortex (MCV) located to the south near BWD, but total lightning data suggests that a majority of the convection has been lightning-free. Given the moist profiles, I expect this to be the norm through the afternoon. While I cannot completely rule out thunderstorms through the 12 UTC TAF cycle, the overall probability appears too low to include in any of the Metroplex TAFs at this time. MVFR ceilings should continue through the day and are expected to lift up above FL020 late this afternoon/early evening. Ceilings will fall quickly thereafter with a return to near IFR possible on Thursday morning. The overall IFR ceiling potential appears marginal in the extended portion of the TAF and have kept ceilings near FL012 as a result. Waco TAF Site---Poor flying conditions are expected to continue through the entire TAF cycle with IFR ceilings expected through at least the afternoon hours before becoming MVFR. Intermittent rain will also occur through the TAF cycle with perhaps a brief break this afternoon. IFR ceilings should return after sunset and continue through Thursday morning. 24-Bain && .PREV DISCUSSION... /ISSUED 355 AM CDT WED AUG 17 2016/ A compact MCV continues to rotate between Burnet and Lampasas this morning. Thunderstorms with heavy rain have already produced over an inch of rain in a short period of time. The MCV should slowly lift northward through the pre-dawn hours with rain and thunderstorms affecting much of the southwest quarter of the CWA through the morning. We have decided to issue a small Flash Flood Watch which will include the counties of Lampasas, Bell, Mclennan, Coryell, Falls and Milam. These counties saw wetting rains over the past few days and this additional activity could result in flash flooding. Although the rain associated with the MCV should shift to the north this afternoon, the southern zones will remain moist and unstable. Therefore, additional activity is expected this afternoon and tonight. For now we will run the Flash Flood Watch through 12Z Thursday. Weak but persistent upper level troughing will remain over North and Central Texas through tonight. Broad large scale lift along with an extremely moist and somewhat unstable environment will produce scattered to numerous showers and thunderstorms again today. Since the warm front has finally lifted north of the region, precipitation will most likely spread much farther north and northwest today than the past couple of days. Heavy rainfall and localized flooding will be the primary hazards. North and Central Texas will remain moist and marginally unstable through the weekend which will warrant the mention of showers and thunderstorms. The best storm chances should shift to the northern half of the region late in the week through the weekend as an upper level trough approaches from the Central Rockies. The upper trough axis will move across the Central Plains on Saturday and allow a cold front to cross the Red River. Lift along the front will bring a good chance of showers and thunderstorms. The front is progged to linger across the region through Monday before lifting into Oklahoma on Tuesday. It is hard to believe that this is late August in North and Central Texas with the abundant cloud cover and below normal temperatures. This pattern should continue for the most part through early next week with highs from the lower 80s to lower 90s and lows in the 70s. The northern zones should even see some lows in the upper 60s behind the cold front early next week. 79 && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
