The episode as NWS FWD wrote it up.
A slow-moving upper trough combined with a stalling front, and a large swath of tropical moisture, to produce record and near-record rainfall across parts of North Texas late August 21 through August 22. Considerable flooding occurred across Dallas County after upwards of 15 inches of rain fell in some areas. Numerous roads, vehicles, homes, buildings and more were flooded and heavily damaged by this event. Damage assessments indicate over 800 buildings and homes were impacted by flood waters, and many were under insured. Preliminary reports indicated 27 destroyed buildings and nearly 300 with major damage. One fatality was reported during this event when a vehicle was swept off a road by a nearby creek.
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 Fort Worth, TX wrote its last area forecast discussion before the first event at Aug 21, 6:05 PM CST, 3 hours 26 minutes earlier.
Area Forecast Discussion National Weather Service Fort Worth TX 705 PM CDT Sun Aug 21 2022 ...New Short Term, Aviation... .SHORT TERM... /NEW/ Update: This afternoon's round of convection has largely moved east of the forecast area, but new development is underway as of 7pm roughly along the I-20 corridor in the presence of low-level moisture flux convergence. As additional mid/upper-level moisture and ascent arrive overnight, a blossoming of convection should occur across North Texas which will shift southward with time heading into tomorrow. Most trends from the previous short term forecast remain on track. The one main adjustment made with this issuance was to lag the PoP trends by about 3 hours based on recent high-res guidance which suggests a slower southward advance tomorrow morning. The main flood threat still looks to be overnight through the morning rush hour in North Texas, and midday/afternoon for areas south of the I-20 corridor. No Flood Watch configuration changes were made with this evening's forecast. -Stalley Previous Discussion: /Today and Tomorrow/ A flood watch remains in effect for North Texas through tomorrow morning with little change made to the ongoing forecast message. While much of today's activity has been showery with only a few embedded thunderstorms, diurnal destabilization should help enhance any ongoing convection and allow for new development of showers and thunderstorms this afternoon. There are a couple prime convective initiation locations...first is across the eastern half of the forecast area as a quick moving outflow boundary races northeast. Expect a broken cluster of storms to develop along the leading edge of this boundary. The next focus area is along a remnant cold pool that has largely become the effective cold front currently analyzed roughly along or just north of the I-20 and I-30 corridors. Weak confluence along this boundary should provide sufficient ascent to develop scattered showers and storms over the next few hours. Today's activity will be largely hit or miss given the lack of a stronger synoptic ascent. With that being said, warm cloud depths are around 15-15.5 kft and the observed PWAT was 2.03" on the FWD sounding. With moisture continuing to surge into the area...any storm that develops over the next 24-36 hours will be very efficient rain producers and heavily influenced by the warm-rain process. Stronger synoptic ascent will move into the area tonight as a low pressure system deepens over the Big Country and moves east late tonight and tomorrow. Expect a gradual increase in precipitation coverage by midnight, with a general west to east progression of the heavy rain axis. There will likely be two axes of heavy rain develop tonight; one following a more north-south orientation along and ahead of a surface trough extending south out of the low and another following a west-east orientation draped across North Texas. The west-east axis should be near the current stalled boundary that will effectively become the warm front tonight when low level warm advection ramps up. Precipitation will be most widespread in the early morning hours tomorrow...roughly saddling daybreak by several hours. This will result in a messy Monday morning commute, particularly for the Metroplex and other Metro areas within the CWA. Over the course of the day Monday, the heavy rain threat will shift southeast in the vicinity of a slow moving cold front expected to exit the forecast area late in the afternoon or tomorrow evening. The flood watch may need to be extended to include this threat in the next several hours as new data arrives. Further north...precip will become more isolated by tomorrow afternoon dry air and subsidence air help stabilize the airmass. Bonnette && .LONG TERM... /Issued 332 PM CDT Sun Aug 21 2022/ /Monday Night Onward/ Unsettled weather and below normal temperatures will continue across North and Central Texas through the weekend, with a lull in activity expected for portions of the region toward the end of the work week. By Tuesday, a weak frontal boundary will approach Central Texas and result in a southward shift of the highest PoPs and rainfall amounts. Precipitation chances will likely come to an end for areas along the Red River by Tuesday afternoon and evening as subsidence increases, but will likely linger through Tuesday night along and south of I-20. Otherwise, the increased cloud cover and rain chances should result in highs mostly in the 80s region wide. The weak boundary, in combination with high PW values, will be the main driver for daily precipitation chances through the end of the work week. There are indications that the boundary will stall south of our region, which would result in lower rain chances across Central Texas, especially on Wednesday and Thursday. Meanwhile, subsidence will continue to increase across the northern half of the region as the mid level ridge builds westward and should keep most of the region rain-free with highs warming into the low 90s. An upper level trough will dig into the Plains by the end of the work week and result in continued rain/storm chances Friday and into the weekend across the region. Garcia && .AVIATION... /NEW/ /00z TAFs/ Numerous aviation impacts are expected during the next 24 hours. Scattered convective development is underway across D10 as of 00z, and some of this activity may impact TAF sites intermittently through the rest of the evening and overnight. The most widespread TSRA at the D10 airports is expected to occur tomorrow morning, mainly from about sunrise through noon. Waco's most likely affected time period will be a few hours later, closer to midday and into the afternoon. All rainfall during this time frame will have the capability of reducing vsbys to IFR. Aside from direct convective impacts, low cigs are also forecast to overspread much of North Texas tonight which could persist well into tomorrow. While these cigs may be occasionally interrupted by mechanical mixing from nearby convection, predominantly MVFR/IFR cigs are forecast from this evening through at least 18z tomorrow. Otherwise, an east wind will prevail through tonight, until a steady veering to northeast and eventually north winds occurs in the presence of an approaching surface low tomorrow morning. -Stalley && .PRELIMINARY POINT TEMPS/POPS...
