The episode as NWS SHV wrote it up.
Surface analysis indicated a stationary front extending across North Texas eastward to near the Arkansas and Louisiana border during the afternoon and evening on May 9th. South of the boundary, a very moist and unstable air mass was in place with MLCAPE values exceeding 4000 J/kg. While low-level winds were relatively weak, moderately strong mid and upper-level winds with deep-layer shear between 60 and 70 knots, aided in steering thunderstorms eastward along and north of the stationary boundary. As a result, these forward-propagating thunderstorms resulted in several reports of large hail, damaging winds and flash flooding across parts of North Louisiana during the afternoon and early evening hours.
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 May 9, 6:05 PM CST, 35 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 705 PM CDT Thu May 9 2024 ...New AVIATION... .UPDATE... Issued at 401 PM CDT Thu May 9 2024 Severe Thunderstorm Watch #224 has been issued through midnight. && .SHORT TERM... (This evening through Friday Night) Issued at 549 PM CDT Thu May 9 2024 A second Severe Thunderstorm Watch #224 has been issued for deep east TX and Toledo Bend Country for this evening until midnight. Large hail and damaging winds with an isolated tornado now possible south of I-20. This activity will continue toward the MS River after midnight. /24/ && .LONG TERM... (Saturday through next Wednesday) Issued at 243 PM CDT Thu May 9 2024 A brief break in active weather will come to an end as the next workweek begins across the Four State Region. This is due to a quasi-zonal synoptic pattern augmented by a series of slower troughs and faster embedded shortwaves across northern Mexico and the Southern Plains. The first of these disturbances will arrive to instigate widespread convection as early as late Sunday into early Monday, while the next disturbance in the parade will arrive as early as Wednesday to keep precipitation chances going through most of the rest of the week. Day 1-7 QPF values of widespread 3+ inch totals are expected with isolated higher amounts possible as a result. Otherwise, temperature maximums/minimums in the 80s/60s will gradually return above normal (maximums approaching 90 once again) after the middle of next week. /16/ && .AVIATION... (00Z TAFS) Issued at 658 PM CDT Thu May 9 2024 Scattered strong to severe convection will remain possible across much of the ArkLaTex through 10/05z. All TAF sites will be affected, but the risk of thunderstorms should generally begin to diminish from northwest to southeast beginning around 10/03z. A few scattered showers will remain possible through the overnight hours, but all rain chances should end before daybreak Friday morning. Outside of convective effects, VFR flight conditions should generally prevail with the exception of possibly a brief period of MVFR ceilings at KLFK. However, VFR conditions with only some high cirrus clouds are expected after 10/13z across the region. CN && .PRELIMINARY POINT TEMPS/POPS...
