The episode as NWS SHV wrote it up.
A weak upper trough shifted southeast from Western Iowa and Eastern Nebraska into Oklahoma and Arkansas during the afternoon and evening of April 30th, reinforcing a weak cold front southeast into Northeast Texas, Southwest Arkansas, and North Louisiana during the evening through the early morning hours of May 1st. A warm, moist, and unstable air mass was in place ahead of the front, with increasing large scale forcing along and ahead of the front and approaching trough resulting in scattered shower and thunderstorm development over portions of Southwest Arkansas and North Louisiana. An isolated severe thunderstorm developed over Northeast Lincoln and Southwest Union Parishes in North-central Louisiana, where damaging winds downed a tree several miles northwest of Downsville along the Lincoln/Union Parish line. These storms weakened and moved out of the region during the early morning hours of May 1st.
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 30, 10:13 PM CST, 19 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 1113 PM CDT Sat Apr 30 2022 .UPDATE... Showers and thunderstorms have reignited along the frontal boundary along a line from near Farmerville, Louisiana to Center, Texas. Therefore, went ahead and extended Severe Thunderstorm Watch 165 through 1 AM as well as including a few more counties and parishes across deep east Texas and north Louisiana ahead of the boundary. Update already out. /05/ && .PREV DISCUSSION... /issued 908 PM CDT Sat Apr 30 2022/ UPDATE... Frontal boundary along a line from near Prescott to Shreveport to Nacodoches gradually moving east. Despite MLCAPE values of 3500 J/kg and steep mid-level lapse rates, convection has dissipated across most of the region with the exception of portions of south- central Arkansas. Latest HRRR model suggests convection to reignite within the next few hours along the front as it shifts south of I-20. Therefore, only made minor adjustments to the watch at this time, removing counties that are now on the drier side of the boundary and leaving the remainder of the watch intact. /05/ PREV DISCUSSION... /issued 635 PM CDT Sat Apr 30 2022/ AVIATION... For the 01/00z TAFs, convection continues along a cold front from near ELD to SHV to near TYR, progressing eastward. The front is forecast to stall across east Texas and north Louisiana overnight before lifting northward on Sunday. VCTS conditions expected across SHV/MLU/ELD/LFK terminal sites through the evening with VCTS conditions continuing across LFK through late morning Sunday. Otherwise, could see tempo MVFR ceilings across mainly MLU/LFK around daybreak, improving to VFR by 01/18Z. /05/ /05/ PREV DISCUSSION... /issued 330 PM CDT Sat Apr 30 2022/ SHORT TERM.../Tonight through Sunday Night/ At 20z, a cold front was located from near Hot Springs, to Ashdown, to Pittsburg, to Athens. Scattered convection has repeatedly tried to develop along the front in Southwest Arkansas but has struggled. Latest radar loops are indicating signs of development farther southwest into Central and East Texas, which suggests convective initiation is underway. Latest mesoanalysis suggests the atmosphere is strongly unstable, with CAPE values in excess of 3000 J/kg. However, there is little in the way of large scale forcing at present. That should change over the next several hours as a weak axis extending southward from a deep upper trough over Nebraska and Iowa moves across the area this evening and tonight. Convective coverage should continue to increase along the front. Despite deep layer shear of only 20 to 30 kts, the strong instability and steep lapse rates should be more than sufficient to support a risk for severe weather posing a risk for large hail and damaging winds. Low-level SRH values are rather modest, but an isolated tornado cannot be ruled out. The convection and the front will continue southward across the area tonight, and the threat for severe weather should end with the frontal passage. After midnight, the risk for any additional severe weather should be limited to Deep East Texas and Central Louisiana where the front is expected to stall. However, what little large scale ascent we have should be diminishing, so the convection should also gradually weaking and decrease in coverage, especially during the early morning hours. However, rain chances will persist along the frontal boundary. The front will rapidly return northward Sunday morning, and a few isolated showers or thunderstorms will be possible across our southernmost zones where moisture availability remains high. Little to no effect on our temperatures will occur, as daytime highs will still climb into the mid 80s areawide on Sunday. Chances for more showers and thunderstorms return Sunday night and into Monday morning as a convective complex develops ahead of the dryline over West Texas and moves east-northeast across the Southern Plains and towards the ArkLaTex. CN LONG TERM.../Monday through Saturday/ Well the weekend cold front is lifting back northward early, but will quickly get another push into our area mid to late day Monday. A short wave over the plains states with the GFS is an open wave of 561dam and the ECMWF is closed low at 560dam. Typically a much slower trend going forward in time and not as progressive open waves with all the rings of isoheights aloft. The ECMWF is the more optimistic for rain for us during this timeframe while the GFS struggles with not much signal anywhere in the midSouth. A deeper upper low will be on approach from midweek. The long range models are in good agreement on position of a core low in the deepening pattern over the Rockies. Once again this feature will activate the lift aloft for the SPC day 6 to highlight for us a Slight risk potentially. By Friday 00Z on Thursday evening we have some timing differences on players, but not so much on QPF signal. This may be the most we see all week with a stronger frontal approach and then a bubble high of 1015mb over MO. Conversely the ECMWF is preceding much slower with the upper on GFS in the western Atlantic, while the ECMWF has the upper low still over KY/TN. Little difference for us in the four state area as we are on the drier side of either solution. Next Saturday looks good for us in either case with a 1019mb air mass over the corn belt and the ECMWF 1017mb over NB/KN. So the bottom line is little change for our work week with more of chance for rainfall than not until that sfc front eases in for late work week. Expect unseasonably warm temps to continue with mid to upper 80s for highs and about 20 degrees cooler by comparison for lows. Even behind this front next weekend, the air will just be cooling down briefly like it has been all Spring. We are seeing average temps warm quickly during May with the longer days. /24/ && .PRELIMINARY POINT TEMPS/POPS...
