The episode as NWS SHV wrote it up.
An upper trough pulled up stationary across Northeast Texas, extreme Southern Arkansas and North Louisiana during the morning of August 18th, which reinforced a weak surface front south into Deep East Texas and Central Louisiana. This front focused an area of low level moisture pooling across these areas, as well as increased large scale forcing as it tapped into strong heating during the afternoon. Weak steering currents were noted aloft, resulting in an area of slow moving thunderstorms developing across Southern Cherokee and much of Angelina Counties in Deep East Texas, with widespread rainfall amounts of two to four inches falling across these areas in a short period of time. Thus, flash flooding was observed in Downtown Lufkin in Angelina County where a couple of roads were covered in high water.
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 Shreveport, LA wrote its last area forecast discussion before the first event at Aug 18, 7:00 PM CST, 1 hour 2 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 800 PM CDT Thu Aug 18 2022 ...New AVIATION... See below for the 19/00Z aviation forecast discussion. .SHORT TERM... (This evening through Friday Night) Issued at 242 PM CDT Thu Aug 18 2022 It has been the coolest day in a while across many portions of the Four State region, especially in some areas north of I-20 where temperatures are really struggling to get to 80 degrees. Clouds have lingered in the area with pockets of showers moving back in from the west across northern zones in the wake of locally heavy showers and storms this morning that trained for several hours over roughly the northeast third of zones. These additional showers moving in are tied more into the elevated front aloft, while the actual surface front stalled from west to east just south of our region is triggering a few more robust thunderstorms in Deep East Texas. Expect the thunderstorm activity to blossom a bit more through the remainder of the afternoon in southern zones with lighter showers and embedded thunderstorms headed toward the heart of the region from the northwest making a little more inroads before tending to dwindle in the evening. The surface front will gradually start to move back north tonight and could continue to kick up some scattered showers and maybe a few embedded thunderstorms late along and south of the I-20 corridor. Low temperatures should range from the upper 60s north to lower 70s south. Heads up that there could actually be some fog late tonight into early tomorrow morning across northern zones and the Arklamiss, particularly in locations which received considerable rainfall early. Tomorrow into tomorrow night, expect the front lifting slowly north through the I-20 corridor to kick off some more widely scattered showers and embedded thunderstorms through the day with generally more sunshine in the afternoon allowing most areas to see temperatures rising to near or just above 90 degrees. Lows tomorrow night will be in the slightly warmer and more muggy low to mid 70s. /50/ && .LONG TERM... (Saturday through next Wednesday) Issued at 242 PM CDT Thu Aug 18 2022 Starting 12z Saturday...Frontal boundary that is expected to bring some rain to the area on Friday should be clear of the area as we move into Saturday morning. The upper air pattern will begin to shift through the day as the upper trough begins to lift out of our region. At the same time, it looks like the Bermuda ridge will begin building into the SE CONUS. Our area should only remain on the western periphery of the ridge, so this should limit how warm we are able to get on Saturday. Nonetheless, Saturday will easily be the "warmest" day of the long term forecast period, with afternoon highs topping out in the lower to mid 90s. At the lower levels, we should see a return of southerly flow which will help push more moisture into the region and should help to initiate some seabreeze and diurnally driven convection by Saturday afternoon, mainly for portions of deep east Texas and much of northern Louisiana. Models continue to hint that longwave troughing will try to re- establish east of the Rockies, which should drive another cool front towards the region. It is looking like this frontal boundary will stall across our northern zones but will bring fairly widespread showers and thunderstorms to the entire region on Sunday. With the increased cloud cover and rain potential, look for afternoon highs on Sunday to range from the mid 80s across our northern zones to the mid 90s across portions of deep east Texas. Rain chances will then continue across much of the region as we move into next week and really through the middle of next week as northwesterly flow aloft is expected to remain in place across the region. Some rain could be heavy at times with this type of set up so we could be in for some high QPF amounts. Speaking of this, 7 day QPF totals are showing upwards of 4-5 inches for portions of the area, with much of that coming early next week. This will likely change some as next week gets closer, but right now that is what the models are suggesting. Remember that movie about the guy who used a car to travel back in time to save the day. I believe it came out in the 80s. Well hope you have a time machine, because we are back to the 80s for most of next week. Monday will see highs range from around 80 degrees to the upper 80s across the region, cooler temps to the north and "warmer" to the south. Actually, lets just make this easier, Monday through at least Wednesday is forecast to feature afternoon highs in the 80s with no 90s in the forecast currently for the entire region. How exciting! /33/ && .AVIATION... (00Z TAFS) Issued at 720 PM CDT Thu Aug 18 2022 For the 19/00Z TAF period, a mix of cigs ranging from MVFR to VFR is observed across our airspace to begin the period. Expect more widespread MVFR cigs overnight, possibly some intermittent IFR and patchy fog reducing vsbys as well through mid-late morning Friday. Convection is currently confined to the LFK terminal, and this should generally remain so over the next few hours. Cannot rule out some isolated convection attempting to shift back north along near the I-20 terminals overnight through early Friday morning, but confidence is low on this scenario despite a stalled frontal boundary slowly lifting back northward. Otherwise, expect slowly improving cigs by midday on Friday with VFR likely returning and light/variable winds trending more E/SE at 5-10 kts on average. /19/ && .PRELIMINARY POINT TEMPS/POPS...

Rain chances will remain in place across portions of the area this afternoon, as a weak surface front continues to slowly push south across the region. Can't rule out isolated damaging wind gusts and frequent lightning in the stronger storms, along with isolated flash flooding from locally heavy downpours. .DAYS TWO THROUGH SEVEN...Friday through Wednesday. The potential for isolated to scattered showers and thunderstorms will remain over portions of the region through the first half of next week, as a series of frontal boundaries and disturbances move across the area. A severe weather threat appears low at this time, but locally heavy rainfall is possible. .SPOTTER INFORMATION STATEMENT... Activation of emergency management personnel, amateur radio operators, and storm spotters will not be needed through tonight.
