The episode as NWS SHV wrote it up.
Northwesterly flow aloft aided in pushing a cold front southward into the region on the afternoon of September 25th. Despite only weak upper-level support, frontal forcing was sufficient to generate scattered convection along the frontal boundary during the afternoon. The atmosphere was relatively uncapped, and with afternoon temperatures climbing into the mid 90s, moderate surface-based instability developed. However, a lack of deep layer moisture appeared to be a limiting factor for any severe weather although classic inverted-V forecast soundings indicated the potential for isolated damaging wind gusts from thunderstorm downbursts in the afternoon. Moisture proved to be sufficient for storms to rapidly develop by mid to late afternoon, quickly accelerating southward and producing sporadic damaging wind gusts across parts of Union Parish.
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 Sep 25, 1:22 PM CST, 2 hours 21 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 222 PM CDT Sun Sep 25 2022 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Monday Night) Issued at 202 PM CDT Sun Sep 25 2022 Strong cold front is beginning its surge south and east into our area attm as sfc pressure rises can be seen north and west of the I-30 Corridor. Likewise, tighter pressure gradient exists across this region as well, not to mention the compressional warming we are seeing in the pre-frontal airmass near and southeast of the corridor. Over the last hour, a broken line of elevated convection has developed north and west of the I-30 Corridor with CB bases more consistent with upper midwest convection. For that reason, will need to watch for the possibility of dry microburst potential mainly through sunset between the I-30 and I-20 Corridors. Did expand low end chance pops just in advance of the current convection on radar through the evening hours but the closer we get to midnight, should really start to see convection loosing its coverage and intensity, as we are only forecasting rain chances less than 20 percent south of the I-20 Corridor after midnight. Cold front pushes through our entire region tonight with post frontal cold air advection in its wake. Did undercut NBM temps slightly overnight, especially across SE OK and SW AR. Stayed very close to NBM temps for daytime highs on Monday as milder and drier air continues to spill into the region. Did continue the trend of undercutting overnight minimum temperatures Monday night, again more so across our northern and northeastern zones as upper 40s cannot be ruled out across our more sheltered areas of SE OK and SW AR. 13 && .LONG TERM... (Tuesday through next Saturday) Issued at 202 PM CDT Sun Sep 25 2022 A very welcomed shift in the pattern is expected over the course of this long-term, with the first extended period of fall temperatures likely. We'll start this long-term under the post-frontal airmass working in over the short-term, with highs Tuesday afternoon across the region ranging in the mid to upper-80s. Temperatures into Wednesday will follow this trend, for pretty much a seasonal feel afternoon wise into Thursday. However, there is a chance that overnight lows will be well below average into Thursday with limited cloud cover and stiff NE winds. The interesting shift, or rather reinforcement in the pattern looks to come on Thursday with the landfall of now TS Ian. Here, the surface trough will extend, or rather be forced down into the region by the landfalling tropical system. Trailing this trough will be another frontal boundary that is also getting pushed through the region by Ian. This should result in another shot of cold air, which will allow for below average temperatures headed into the weekend. Given how long-range guidance tends to plot warmer than actual during the overnight hours, widespread 40's are not out of the realm of possibility Thursday and Friday nights. /44/ && .AVIATION... (18Z TAFS) Issued at 1100 AM CDT Sun Sep 25 2022 While isolated to widely scattered convection will be possible later this afternoon through this evening near and south of the I-20 Corridor ahead of a strong cold front that will be moving through our airspace, storm coverage does not warrant mentioning in the 18z TAF package. Will instead handle anything close to an airport with an AMD if necessary. Otherwise, mid level cloud cover will be in an out across our airspace ahead of the front and post frontal as well but all ceilings should remain VFR in nature. Look for WNW winds prevailing near 10kts, with those winds quickly veering around to a NW, N and eventually NNE direction during this TAF period as well. 13 && .PRELIMINARY POINT TEMPS/POPS...
