The episode as NWS SHV wrote it up.
A broad complex of showers and thunderstorms with associated heavy rainfall developed across areas of Deep East Texas and West Central Louisiana by mid to late morning on July 26th. This occurred within an elongated axis of upper-level energy observed along much of the middle and upper Texas coast and up across interior areas of East Texas around the eastern flank of a broader mid-level trough over the Southern Plains. This energy interacted with a very deep tropical air mass and axis of stronger instability that was pooled up across the northwest Gulf of Mexico and farther inland to a lesser extent. MLCAPE values of 1500 to 2500 J/kg were noted across these areas with precipitable water values of 2 to 2.25 inches. As a result, multiple reports of flash flooding were received across parts of Deep East Texas.

Area Forecast Discussion National Weather Service Shreveport LA 213 AM CDT Fri Jul 26 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Friday through Saturday) Issued at 1254 AM CDT Fri Jul 26 2024 Upper trough axis remains anchored across Central and SE TX, northeast into the Middle Red River Valley of NE TX, NW LA and SW AR and into the Tenn and Ohio Valley and will remain anchored across this location at least through tonight. Currently we are monitoring an area of mostly light to occasional moderate showers and isolated thunderstorms extending from SE TX into our part of Deep East Texas, steadily moving north, northeast into portions of NW LA. This region is embedded in an areas of SSW low level winds which happens to coincide with an area of higher PWATs near or slightly above 2 inches. Upper forcing in regards to the trough, not to mention slight isentropic forcing will aid in this area of convection continuing to grow and expand this morning. Given the heavy rainfall that has fallen across this region over the last 72 hours and the expected rainfall again today, issued a Flood Watch for Deep East Texas and Sabine Parish in West Central Louisiana through 6 pm this evening. The heaviest rainfall will likely occur this morning and therefore the watch could be cancelled early if rainfall rates and/or coverage diminish more quickly. Low level winds should begin to decouple by late this afternoon which should ease rainfall rates across our southwest but not before additional rainfall amounts of one to three inches will be likely across this corridor with isolated higher amounts. Otherwise, likely to categorical pops are warranted again today across all but near and northwest of the I-30 Corridor where pops were tapered back to chance variety. As we transition into tonight, there will begin to be a slight displacement of the upper level trough back to the northwest. This change is subtle initially but in turn, it will allow for more of an increasing SSW low level return across our western half which should be a little further north and west of where convection has been developing nocturnally the last 2 nights. Having said this, didn't feel comfortable going any higher than chance pops, more heavily weighted across our western half tonight with lower chance pops across our eastern half. That trend of a retrograding upper level trough axis will continue into Saturday with higher pops across our western half during the first half of the day with pop coverage awaiting daytime heating to get going good across our eastern half. Pop coverage should be scattered to numerous by late morning into the afternoon hours on Saturday as a result. Did not deviate much from NBM temps through the short term as rain and cloud cover should help keep values at bay today with perhaps slightly warmer temps into Saturday. 13 && .LONG TERM... (Saturday Night through Friday) Issued at 1254 AM CDT Fri Jul 26 2024 By Sunday, even through the upper trough continues to slowly lift back to the north and west, there is enough forcing, combined with daytime heating with continued moisture in place for scattered to numerous convection once again across our region. Sunday should mark the end to the inflated pops as there will be a pattern shift underway to begin the start of the upcoming work week. The above mentioned upper trough axis quickly ejects out into the Ohio and Tenn Valley Sun Night into early Mon with upper ridging left in its place across the Upper and Middle Red River Valley. Kept some small pops across our southeast half only for Monday and this will be mostly of the daytime heating variety but the upper ridge axis really begins to expand Tue thru at least Thu of next week. This pattern shift will result in very little if any precipitation chances and a quick uptick in temperatures with afternoon highs mid to late next week closer to normal for the transition into early August, in the middle to upper 90s. There are some indications that the above mentioned upper ridge may begin to rebuild back to the north and west, or into the Intermountain West with a longwave trough beginning to reestablish itself across the middle and lower Miss Valleys by the end of next week and just beyond this 7-day forecast. This would result in increasing rain chances once again and perhaps a cool down but again, that's assuming the ridge can retrograde that far to our north and west. 13 && .AVIATION... (06Z TAFS) Issued at 1222 AM CDT Fri Jul 26 2024 Convective showers ongoing across the SW terminals tonight as the shear axis overhead locks in for another TAF package that showcases SHRA/TSRA through the afternoon. Latest hi-res solutions show this carrying through 00z and not letting up until after sunset, with VCSH and some -RA/BR expected through the end of the period. Along with this, BKN/OVC sub 5000ft ceilings are to be expected through the period. Buying any significant changes in timing or intensity, expect a similar 12z package with additional coverage expected across the terminals closer to sunrise. RK && .PRELIMINARY POINT TEMPS/POPS...

Scattered to numerous showers and thunderstorms are once again in the forecast today through tonight across the entire Four State Region. Some of this could be heavy at times, especially this morning and into the afternoon hours across portions of the region. While no severe weather is expected, excessive heavy rainfall could result in flash flooding across more flood prone areas. The areas of greatest concern from heavy rainfall should be confined to the southern half of Northeast Texas, Northern Louisiana and far Southern Arkansas. Look for storm coverage to diminish by late this afternoon into this evening, before increasing once again by late tonight. .DAYS TWO THROUGH SEVEN...Saturday through Thursday. Scattered to numerous showers and thunderstorms will continue through at least Sunday across portions of the Four State Region. Rain chances should diminish as we transition into the upcoming work week. Decreasing rain chances will result in hotter temperatures with readings by mid to late week returning to the middle and upper 90s. These temperatures when combined with relatively high afternoon humidity will result in afternoon heat indices nearing or exceeding 105 degrees by the middle to later half of next week. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed.

The areas of greatest concern from heavy rainfall should be confined to areas near and around the Lower Toledo Bend and Sam Rayburn Country of Deep East Texas into West Central Louisiana. Look for storm coverage to diminish by late this afternoon into this evening. .DAYS TWO THROUGH SEVEN...Saturday through Thursday. Scattered to numerous showers and thunderstorms will continue through at least Sunday across portions of the Four State Region. Rain chances should diminish as we transition into the upcoming work week.
