The episode as NWS SHV wrote it up.
A broad upper trough extended south from Southern Minnesota into the Ozarks during the afternoon of April 24th, with a secondary shortwave trough swinging southeast over Eastern Colorado and Western Kansas, which entered Oklahoma during the evening hours. A cold front moved slowly southeast across Northwest Arkansas, Southeast Oklahoma, into Northern and West-central Texas during the afternoon, with large scale forcing ahead of this second shortwave trough focusing showers and thunderstorms along the frontal zone where daytime heating resulted in increased instability over Southeast Oklahoma. Thus, strong to severe thunderstorms developed as a result, which moved across portions of McCurtain County downing trees and power lines and also producing large hail before exiting the area by mid-evening.
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 Apr 24, 5:53 PM CST, 1 hour 20 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 653 PM CDT Sun Apr 24 2022 .AVIATION... For the 25/00z TAFs, VFR conditions currently prevail at all terminals, but showers and thunderstorms will move into Southeast Oklahoma and Northeast Texas before 25/06z ahead of a cold front. The convection will gradually spread southeast through the period affecting all TAF sites. MVFR/IFR ceilings should develop ahead of the front areawide during the early morning hours. Any IFR ceilings that occur should lift back into the MVFR range after the frontal passage. The convection should gradually diminish from northwest to southeast. Behind the front, winds will become northerly and increase to around 10 kts with a few gusts approaching 20 kts. CN && .PREV DISCUSSION... /issued 322 PM CDT Sun Apr 24 2022/ SHORT TERM.../Tonight through Monday Night/ The afternoon sfc analysis indicates that the cold front continues to make slow progress SE across extreme NW AR/SE OK and portions of WCntrl TX, with convection increasing along and behind the frontal zone. This is in response to increasing large scale ascent ongoing along the base of the lead shortwave trough, and just in advance of a secondary trough over Ern CO/NW KS rotating beneath the NE MN closed low lifting NE into Srn Ontario attm. Low level convergence is expected to increase along the H850 trough by this evening in response to a strengthening 35-40kt Srly LLJ, further enhancing the ongoing convection over N TX into Srn/SE OK/NW AR. This axis of heavy rainfall remains progged to linger mostly NW of McCurtain County OK through much of this evening, before drifting SE with the front mainly after 06Z Monday. The progs do suggest that this convection will gradually shift SE into NE TX/SW AR through 12Z, with any heavy rainfall mostly brief and localized, and amounts of around an inch or less, with locally higher amounts up to two inches possible, mainly across portions of McCurtain County OK and portions of E TX. Thus, a Flash Flood Watch will not be needed as these areas can easily take these totals. Have maintained categorical pops late tonight for areas along/NW of I-30, tapering pops down to chance pops across Lower E TX/extreme NW LA and SCntrl AR. Meanwhile, the ongoing isolated convection this afternoon over the Ern sections of NCntrl LA, associated with theta-e ridging over these areas, should persist until late afternoon before diminishing with the loss of heating. Convection should continue to spread SSE along/behind the front across the remainder of E TX/N LA after daybreak Monday, with the brief heavier rains shifting S of the region by early afternoon with the departing front. However, post-frontal convection will linger along/S of the H850 front through the afternoon and evening, until the next developing shortwave trough shifts SE through the Cntrl/Srn Plains Monday night beneath the longwave trough. QPF amounts will also be much lighter Monday afternoon and night given the weaker forcing aloft along the H850 front, but confidence does remain somewhat higher with light measurable QPF mainly along/S of I-20, where likely pops were maintained. Did keep slight chance/chance pops going farther N in case elevated forcing is strong enough farther N to wring out areas of -RA. Did not deviate much from the NBM temps in the short term period, but did lower max temps Monday slightly along/behind the front given the persistent rains and thick cloud cover. 15 LONG TERM.../Tuesday through Saturday Night/ Post-frontal conditions will offer a brief reprieve from above normal temperatures through the middle of the week before the next disturbance potentially arrives by the weekend. Until then, dew points will fall below the 50-degree mark through the middle of the week, allowing maximum temperatures in the low to mid-70s and minimum temperatures in the upper-40s and lower 50s for comfortable outdoors conditions. Quasi-zonal, northwesterly flow aloft will prevail through the rest of the week with embedded shortwaves being the primary source of any chances of precipitation, all of which are expected to be meager until the weekend. The first embedded shortwave arrives by Thursday with more of an effect on cloud cover than precipitation across northern zones. Northeasterly surface winds will gradually veer through the middle of the week to become southerly winds once again, and the 60-degree isodrosotherm will also gradually shift east from East Texas through the rest of the Ark-La-Tex by the end of the week. As a result, maximum temperatures will return back above average by the end of the week. The next shortwave is anticipated to arrive by next weekend, however, uncertainty begins to increase at this point as long-range guidance solutions diverge in timing and intensity. What is more certain involves warmer than average temperatures and prolonged moist southerly flow that will enhance the probability for convection ahead of a potential disturbance that is yet to be resolved in detail. /16/ && .PRELIMINARY POINT TEMPS/POPS...
