003 FXUS64 KSHV 230534 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 1134 PM CST Sat Nov 22 2025 ...New DISCUSSION, SPOTTER INFORMATION STATEMENT... .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... (06Z TAFS) Issued at 1015 PM CST Sat Nov 22 2025 All TAFs are VFR currently, although MVFR cigs with bases from 2 to 3k feet AGL are in SE OK and portions of SW AR, but low ceilings later tonight getting into TXK and ELD have been delayed over what was represented in the 00Z TAF package. Some visibility reductions are possible in all areas, although any dense fog should be isolated and is not represented in any TAFs through tomorrow morning. Farther south into the I-20 corridor, there is more confidence in patchy IFR ceilings and maybe some visibility reductions in SHV and MLU from approximately 6 AM through 10 AM. This was represented in most of these TAFs to one degree or another, although confidence is now higher that TYR and LFK may remain entirely (or largely) VFR late tonight into early tomorrow morning. Above the low stuff, expect increasing cirrus from 20 to 25k feet through the night into tomorrow morning. Sub VFR conditions could linger a while into tomorrow morning at ELD/TXK/MLU, but confidence is decent that VFR conditions will prevail in all areas by noon. Otherwise, current light winds from the northwest at around 10 mph will become light this evening and gradually veer to the northeast and east by tomorrow morning. These winds will eventually start veering to the southeast tomorrow night in advance of an approaching storm system that will bring rain, storms, and bad flying conditions to the area Monday and Monday night, although anything more than isolated showers and not expected before the end of the TAF period...and then mainly confined to TYR and TXK. /50/ && .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...
