933 FXUS64 KSHV 231256 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 656 AM CST Sun Nov 23 2025 ...New AVIATION... .KEY MESSAGES... Issued at 1024 PM CST Sat Nov 22 2025 - One more dry day areawide on Sunday before we begin to see moisture returning late Sunday/Sunday Night in advance of our next storm system. - Still looking at a window for excessive heavy rainfall and possible severe weather beginning to impact the region on Monday, continuing through at last Monday Night. - Colder air still poised to move into the region during the day Wednesday and through the end of the holiday week with near freezing overnight low temperatures across our northern zones for Wed Night and again Thu Night. && .DISCUSSION... Issued at 1024 PM CST Sat Nov 22 2025 Still seeing post frontal northwest winds across our region late this evening and temperatures a little more indicative of late November compared to what we`ve seen through most of this month. Low level post frontal cloud cover remains across portions of SE OK and Central AR and this moisture will try to backdoor into our region from the northeast overnight and on Sunday. These clouds may be stubborn to break out during the morning but think we will eventually see some scattering out of this moisture if not by late morning then by afternoon. Northeasterly winds will become near easterly by afternoon which, assuming we see the cloud cover diminishing during the day, we should see temperatures warming into the middle 60s north to the lower and middle 70s south for Sunday. Beyond Sunday, we begin to watch a vigorous upper trough eject out of the Four Corners Region of the Country and into the Southern Plains late Sunday Night and during the day Monday. We will likely begin to see returning showers and thunderstorms in advance of this trough late Sunday Night but especially during the predawn hours Monday Morning across our far northwest zones. More of our region will await more broad forcing in association with the upper trough ejection during the day Monday to see more widespread convection across mostly our northwest half during the day Monday, with convection moving into our southeast half Monday Evening through the overnight hours. At this time, the heaviest rainfall appears to be mainly to the north and northwest of the I-20 Corridor of NE TX, SE OK and SW AR. This will be the same general area where beneficial rainfall fell with our last trough on Thursday. While much of this region remains in a Slight Risk for Excessive, Heavy Rainfall in the Monday/Monday Night timeframe, this area should be able to take a good 1-3 inch rainfall without widespread flooding impacts and therefore, no Flood Watch will be issued with this package. Concerning severe weather potential, SPC did upgrade our region to a Slight Risk for severe thunderstorms, again in this Monday/Monday Night timeframe and this is certainly warranted given the consistency in the models when it comes to low level directional shear and bulk shear progs. Still what is uncertain is the amount of surface based instability as much of this instability may be slightly elevated due to a low level capping inversion. This could mean everything when it comes to a more serious risk of tornadoes with this convection vs more of an isolated hail and/or wind threat if the storms remain mostly elevated. Regardless, the convection should exit our region to the southeast early on Tuesday. Strong cold front to enter our region from the northwest late Tuesday Night and into the day Wednesday bringing and end to high temperatures in the 70s for the remainder of the holiday week. We should really feel the chill overnight Wed Night and again Thu Night with low temperatures in the 30s across most areas Wed Night and across the east Thu Night. Near freezing temperatures will be possible across our far northern and northeastern zones both nights. Our next trough begins to take shape across the Intermountain West once again by next weekend. With upper southwesterly flow returning, progs are hinting at possible showers and storms returning to our region along with a warming trend to begin the weekend. 13 && .AVIATION... (12Z TAFS) Issued at 642 AM CST Sun Nov 23 2025 For the ArkLaTex, falling short on the low categories this morning for most, but some MVFR cigs for KMLU/KELD and some patchy light BR. NE/E winds today 5-10KT with moistening SW flow aloft increasing high clouds for now, but low VFR cigs and middeck will begin the increasing coverage of showers and TS overnight into Monday, some may be SVR with locally +TSRA. Our winds veer around to SE/S Monday and eventually SW to NW early on Tuesday driving out the moisture and chilling down temps for the holiday travels. /24/ && .SPOTTER INFORMATION STATEMENT... Issued at 1024 PM CST Sat Nov 22 2025 Spotter activation is not expected over the next 24 hours. However, spotter activation may be needed Monday and Monday night due to the threat of severe weather and heavy rainfall. 13 && .PRELIMINARY POINT TEMPS/POPS...
