The episode as NWS FWD wrote it up.
An upper level storm system deepened over the Southwest U.S. before advancing east into the Plains. This system was accompanied by a slow-moving cold front, and together produced multiple days of showers and thunderstorms across the region. A few severe storms and additional flooding occurred in some areas.

Area Forecast Discussion National Weather Service Fort Worth TX 333 PM CDT Sun Oct 7 2018 .SHORT TERM... /Through Tonight/ Broad, weak ascent continues overhead downstream from a deep upper trough, and this lift is aiding in the development of diurnally-driven convection across the region. Instability remains high with SBCAPE values over 2000 J/kg across most of the area, but both lift and shear are both fairly weak. These factors continue to limit the intensity of convection, although instability alone may allow a couple storms to become strong through late afternoon/evening. Strong winds will be the main hazard with more robust convection along with a low-end hail threat. Quality moisture also remains in place, and most convection has been able to support rain rates of 1-2" per hour. However, the fast cell motion and scattered nature of convection will limit a potential for prolonged heavy rain and flooding at any given location. Most of this activity should begin to decrease after 8 PM with the loss of daytime heating and the associated buoyancy. Overnight, a relative lull in rainfall is expected across most of the forecast area. The one area to keep an eye on will be to our west where a north-south axis of showers and thunderstorms should be in progress. Most of this activity should remain west of the forecast area overnight, fueled by stronger ascent from a disturbance pivoting through the deep upper trough, along with the low-level jet intensifying to 40-50 kts. Convection will be training from south to north within this region of ascent, and there are likely to be some heavy rain/flooding issues associated with it. Should this activity shift farther east into the forecast area, the heavy rainfall potential will need to be monitored. -Stalley && .LONG TERM... /Monday through Sunday/ Similar to this morning, convection should be ongoing to the north and west of the region Monday morning as the slow moving upper trough to the west gets a little closer. The airmass will remain very moist and moderately unstable across the region through the day and we should see an increase in diurnal showers and thunderstorm by late morning into the afternoon. The best coverage of showers/storms will still be to the west of I-35 where some stronger forcing for ascent will be present. Farther east, similar to this afternoon, coverage will be more scattered, but an isolated strong to severe storm can't be ruled out. By Monday night, the upstream trough will finally begin to eject eastward into the Plains. Stronger forcing for ascent will overspread North Texas and we should see a rapid increase in the coverage of showers and thunderstorms, especially across our far northwest counties. This activity should begin to organize into a squall line during the early morning hours Tuesday and will march across the region through the day. High moisture content and steepening lapse rates aloft, along with moderate deep layer shear will be supportive of a severe weather threat during the day Tuesday. The primary threat will be damaging winds associated with the organized squall line, however, if any isolated storms can develop ahead of the main line, they would have an associated threat for tornadoes. This overall threat appears low at this time, but can't be discounted entirely. High PoPs will be in place areawide through the day Tuesday, but showers and storms should rapidly end from west to east through the day. Wednesday and Thursday are shaping up to be pretty nice days with slightly drier air filtering in and broad subsidence around the western periphery of a landfalling tropical cyclone along the northern Gulf coast. The nice weather will be short lived though as weak low/mid level ridging slides eastward and Gulf moisture comes streaming back into the region by the end of the week. We'll also be watching the remnants of Sergio in the eastern Pacific as it spreads inland over northwest Mexico along with a cold front sliding southward through the Plains. All of this could make for another heavy rainfall event somewhere across Central or North Texas by next weekend. For now, we'll leave PoPs fairly low from Friday through Sunday, primarily because of the very large uncertainty in timing/location of these features, but nonetheless we'll have to watch this. Otherwise, temperatures are expected to be below normal for the latter part of the week into next weekend. Dunn && .AVIATION... /Issued 1228 PM CDT Sun Oct 7 2018/ /18z TAFs Scattered showers and storms are in progress across much of North and Central Texas at midday, and coverage should continue to increase through the afternoon hours. In addition, surface heating will contribute to greater instability, so TS activity is expected to be on the increase during the next 6 hours. Will continue to advertise VCSH for another hour or two before including VCTS at all airports through the late afternoon and early evening hours. Most activity should wane with loss of heating after 01-02z. The exception will be activity farther west of the airports which will persist into the overnight hours, and may continue to affect departures/arrivals from the west. Winds will remain breezy at 10-20 kts out of the south throughout this time period. Low MVFR stratus will return to all airports on Monday morning with some brief IFR possible as well. A few warm advection showers will be possible after daybreak Monday morning, similar to this morning. Another round of scattered showers or thunderstorms is expected on Monday afternoon and evening which may need to be addressed in subsequent TAFs. -Stalley && .PRELIMINARY POINT TEMPS/POPS...

Scattered thunderstorms will continue through this evening. An isolated strong or marginally severe storm producing strong winds may occur, but widespread severe weather is not expected. Storms will continue overnight west of Highway 281 where a threat for heavy rain and flooding may occur. .DAYS TWO THROUGH SEVEN...Monday through Saturday. Thunderstorm chances will continue on Monday, mainly west of the I- 35 corridor. Heavy rain will be the primary concern, but a severe storm with damaging winds will also be possible Monday afternoon. Widespread heavy rain is expected Tuesday and Tuesday night as a complex of storms moves through the region. The heaviest rain will be north of the I-20 corridor where new amounts of 2 to 3 inches are possible. Flooding may result from the runoff, especially where heavy rain also occurs in preceding days. Although flooding will be the primary concern, the severe threat may increase on Tuesday. Damaging winds will continue to be the main threat with any severe storms, but unlike previous days, the potential for supercells will introduce a hail and tornado threat as well. After a brief interlude of pleasant weather Wednesday and Thursday, thunderstorm chances will return Friday and Saturday. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time.
