The episode as NWS SHV wrote it up.
Strong to severe thunderstorms developed along the Middle Red River Valley during the early morning hours on May 24th. These thunderstorms intensified in vicinity of deeper theta-e advection via the low-level jet on the southern fringe of a residual cold pool. The convective environment supported increasing storm organization, with effective shear around 50 knots. Strong to severe wind gusts accompanied the more discrete updrafts that managed to develop as convection became fairly well-organized, aided by persistent low-level warm advection within a thermodynamic environment characteristic of 2000 to 3000 J/kg mixed-layer CAPE. As a result, a few reports of isolated damaging wind gusts and flash flooding were received across parts of McCurtain County.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at May 23, 11:28 PM CST, 2 hours 6 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 1228 AM CDT Fri May 24 2024 ...New AVIATION... .UPDATE... Issued at 1043 PM CDT Thu May 23 2024 The SPC has issued SVR TS watch #298 including our I-30 corridor. && .SHORT TERM... (Tonight through Saturday Night) Issued at 1043 PM CDT Thu May 23 2024 Well the question of a left turn in W AR or across SW AR for the expected new convection has been determined by a higher power. So to update the evening update, we have returned "some maybe severe" to our posted likely pops across I-30 and north. Large hail and damaging winds will be primary issues to be watched, but it is springtime, so keep the NOAA WX radio bedside for those in our SVR Thunderstorm watch area into the overnight. /24/ && .LONG TERM... (Saturday through next Wednesday) Issued at 316 PM CDT Thu May 23 2024 As of this writing, the daytime hours Saturday look to largely be dry. As a more robust threat for severe weather takes shape to our west and north, impacts may manage to graze the northernmost zones of the ArkLaTex, primarily along and north of the I-30 corridor, and mostly likely following the pattern of recent days with impacts beginning after 00Z Sunday, continuing through the night and coming to an end by Sunday morning. Sunday and Monday will see a continuation of this timing pattern, as the morning and afternoon will likely be dry, with the best chances for some scattered showers and storms along our northeast fringes near or after sundown, with more widespread impacts possible Monday afternoon and overnight with the frontal passage. The weekend will see persistent southerly flow reinforce the warming trend experienced this week, with widespread highs in the low 90s across the region and an increase in highs climbing into the middle 90s, in concert with dewpoints in the low to mid 70s, these will make for uncomfortable to oppressive humidity for portions of the region before a regime change finally takes effect. Said pattern shift looks to manifest during the day Monday, as the upper level troughing associated with the surface boundary finally gets nudged north and east by a building ridge out of the west. This transitional pattern will allow for northwesterly flow to return area lows to the 60s and highs to the 80s through at least the middle of next week, followed by a fairly quick return to the 90s by the end of this extended forecast period, with mostly dry conditions through Tuesday and Wednesday and the next notable chance of rainfall arriving before dawn next Thursday. /26/ && .AVIATION... (06Z TAFS) Issued at 1228 AM CDT Fri May 24 2024 South winds 10 to 15 knots to persist through the terminal forecast period ending 25/06Z. Low-level moisture will bring MVFR ceilings to the region from 25/09Z through 25/15Z with ceilings lifting to VFR thereafter. Otherwise, VCTS conditions expected after 25/02Z across TYR/GGG/TXK/ELD terminals with tempo TSRA conditions expected across TYR/TXK/ELD after 25/04Z. /05/ && .PRELIMINARY POINT TEMPS/POPS...

Strong to severe thunderstorms will be possible once again today, into the evening and overnight hours across much of the Four State Region. Large hail, damaging thunderstorm wind gusts and locally heavy downpours will be the primary threats with an isolated tornado threat as well. The severe weather threat should end from northwest to southeast across the Four State Region overnight tonight. While widespread flooding is not likely through tonight, flooding of low lying and flood prone areas will be possible with heavy downpours through tonight. .DAYS TWO THROUGH SEVEN...Friday through Wednesday. Severe weather will be possible once again late Friday into Friday Night and late Saturday into Saturday Night across mainly portions of Northeast Texas, Southeast Oklahoma and Southwest Arkansas. Large hail and damaging thunderstorm wind gusts will again be the main threats Friday and Saturday. A strong cold front will move through the region on Memorial Day and Monday Night bringing with it another chance of thunderstorms. Before the cold front arrives late on Monday, we will see some of the hottest temperatures of the late Spring Season with afternoon high temperatures both Saturday and Sunday in the lower to middle 90s. Combine this with high afternoon humidity and heat indices could approach 105 degrees across some locations. .SPOTTER INFORMATION STATEMENT... Spotter activation will be possible later today through this evening. 13
