The episode as NWS SHV wrote it up.
A surface low was centered over the southern Texas Panhandle with a stationary front extending through southern Oklahoma into southern Arkansas eastward into northern Mississippi. A dry line extended southward from the surface low through west Texas into the Big Bend Country along with a cold front draped southwest from the surface low into southeast New Mexico. Aloft, an upper-level low was initially centered just east of the Rockies in eastern Colorado before tracking into eastern Kansas and eventually into the Ozarks on the morning of May 6th. Meanwhile, the surface low shifted along the Red River Valley with the cold front trailing along the I-35 corridor, shifting farther east into the Ark-La-Tex region on the afternoon and evening of May 5th. As a result, this led to widespread strong to severe thunderstorms during the latter half of the day on May 5th with peak daytime heating aiding in a very unstable environment ahead of the cold front and upper low which were both advancing eastward from the Southern Plains.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at May 5, 12:24 PM CST, 28 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 124 PM CDT Thu May 5 2022 .AVIATION... For the 05/18z TAFs...A mix bag of flight conditions, as storms have developed across portions of East Texas. Look for mention of showers and thunderstorms for most terminals for the remainder of the afternoon, with hail and severe wind possible. Convection should move out of the region by 06/03z, with clearing cigs afterwards through the end of the TAF period. Winds will become westerly in wake of the convection, as a frontal boundary moves across the region. /20/ && .PREV DISCUSSION... /issued 1229 PM CDT Thu May 5 2022/ UPDATE... Tornado Watch 181 along with a Flash Flood Watch across portions of SW Arkansas was added during this update. Otherwise, the remainder of the forecast remains on track. Showers and thunderstorms continue to develop across portions of East Texas, extreme SE Oklahoma, an adjacent SW Arkansas this morning. Look for these storms to develop into a strong linear line, with all modes of severe weather possible as the line of storms push eastward today. && PREV DISCUSSION... /issued 334 AM CDT Thu May 5 2022/ SHORT TERM.../Today through Friday/ Good morning and Happy Cinco de Mayo! The forecast for today is nacho average forecast for the 5th of May so let's get into the details. Surface analysis from early this morning is showing a surface low centered over the southern Texas Panhandle with a stationary front extending through southern Oklahoma into southern Arkansas and eastward into northern Mississippi. A dryline extends southward from the surface low through west Texas into Big Bend Country. A cold front also drapes southwest from the surface low into southeast New Mexico. Looking aloft, an upper-level low is centered over southeast and east central Colorado. This upper- level low is expected to track into eastern Kansas this morning and eventually into Ozarks by Friday morning. The aforementioned surface low will shift northeastward towards the Mississippi Valley through the day. The cold front will trail behind the surface low through Oklahoma and central Texas through the day today. This will be the feature that will bring a strong line of thunderstorms through our area today. We are seeing a large amount of convection on national mosaic radar imagery this morning from central Oklahoma eastward into western Arkansas. There was some uncertainty to whether or not the storms this morning would persist or intensify through the morning, but it appears they are doing a good job at persisting. Regardless of what happens with this early morning convection, we should see a line of organized convection develop late this morning/early this afternoon from central Texas into southwest Arkansas as the cold front begins to push into the region. MLCAPE around 2000 J/kg and around 45 kts of effective shear across the region should support this line of thunderstorms this afternoon. Most of the convection is expected to be focused along the frontal boundary which will mainly bring a threat of damaging wind gusts. That being said, there does remain some potential for embedded supercells within the line or even out ahead of the line that could bring a threat for hail and a few tornadoes. This line should begin to develop late this morning across our far northern zones. Expecting it to reach the heart of our forecast area generally from Tyler, TX to Shreveport, LA to El Dorado, AR by early this afternoon before continuing to track to the southeast through the remainder of the day and into the early overnight hours. In addition to the threat for damaging winds and embedded tornadoes and isolated hail events, moderate to heavy rainfall rates on the east side of this low pressure where the moisture axis is located will increase the threat for isolated flash flooding to occur. Debated back and forth this morning with issuing a Flash Flood Watch, however, after some collaboration with our neighbors we have decided to hold off at this point. Total QPF amounts will range from around 1-4 inches across most of the area with the higher amounts expected northwest of a line from near Tyler, TX to the Texarkana area. Model guidance suggests that there will be one or two areas of maximum rainfall across this area but the exact location of this maxima could vary, which is part of why we decided to hold off on a watch. Followed NBM guidance for temperatures for today and Friday as I felt the incoming severe weather threat needed more of my attention this morning. Afternoon highs will range from the mid to upper 70s across our northern zones, generally along and north of I-30 while the remainder of the area will be in the 80s. Overnight lows will range from the lower 50s across our northern zones to the mid 60s across our southern zones. Friday will see temperatures in the 80s across the region. /33/ LONG TERM.../Friday Night through Wednesday Night/ A stationary bndry will remain in place across portions of E TX/N LA Friday night, with this bndry possibly being nudged a bit father S overnight in response to weak sfc ridging that will build S from the Midwest/Ozarks region. This will result in the last cool, comfortable morning through the long term period, and possibly for the remainder of the spring for that matter, before a drastic pattern change takes place this weekend through much of next week. The progs continue to advertise that subtle ridging aloft will build into the Cntrl/Srn Plains Saturday, before expanding NE through the MS Valley/Great Lakes Region into much of Ontario/Quebec. This ridge axis is progged to amplify further to near 591 decameters from S TX NE through the MS Valley/Great Lakes Region through midweek next week, with the blocking pattern becoming established as the closed low (which will bring the severe convection to much of our region today) meanders over the Wrn Atlantic, and longwave troughing develops and persists across the Great Basin and Intermountain West. Thus, the first 90 degree temps are expected over much of the region Saturday as the stationary front begins to work its way back N as a warm front, before increasing subsidence beneath the expanding ridge late this weekend results in much above normal and in some cases, near record high temps over the region Mother's Day Sunday through much of next week. In fact, the NBM continues to trend with temps hotter than Hades across much of E TX/N LA, with temps in the upper 90s and thus setting numerous records. Given the moist soil conditions in wake of above normal rains that have been observed across the region in the last 60+ days, have continue to shave off these temps some 1-4 degrees especially over E TX/N LA, although temps will rival records for much of next week. Should also see bouts of morning low stratus, before these mix out into a sct cu field each day, with Srly low level winds strong enough to keep the air mixed and thus a bit cooler than the hotter NBM. Strong subsidence beneath the ridge will also maintain dry conditions throughout the entire long term period, before the synoptic pattern tries to break down to some extent as the Wrn Atlantic closed low retrogrades W late next week into the SE CONUS. Fortunately, adequate mixing of the slightly drier air above the bndry lyr each day should result in heat indices remaining at or below 100 degrees late this weekend through next week, and thus, no heat headlines are anticipated attm. 15 && .PRELIMINARY POINT TEMPS/POPS...
