654 FXUS64 KSHV 111533 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 1033 AM CDT Sun Aug 11 2024 ...New UPDATE, SHORT TERM... .UPDATE... Issued at 1017 AM CDT Sun Aug 11 2024 Tweaked slight chance pops down over the Texarkana vicinity. && .SHORT TERM... (This afternoon through Monday) Issued at 1017 AM CDT Sun Aug 11 2024 Light NE winds over our I-30 corridor and I-20 in most of LA, but SE winds are into the Shreveport/Bossier metro area. Much of E TX is S/SE with fair skies most everywhere except I-30. A decaying complex of showers and thunderstorms continues to sink S/SEward. Most of our pops covered this activity with slight to chance wording, but a little spoke has been persistent from near Mt. Pleasant a couple hours ago, to now in Bowie and Cass Counties. Light amounts here and in the Texarkana vicinity will continue for a few hours as this nocturnal push is buffed away by fresh heating. Currently, we see mid 70s north of I-30 under the bulk of cloudiness and most rain area reaching the ground. Elsewhere, a range of low to mid 80s in the sunshine will tack on another 10 degrees. So no changes needed to temps are needed. /24/ && .LONG TERM... (Monday Night through Sunday) Issued at 224 AM CDT Sun Aug 11 2024 Heating trend is going to continue into Tuesday, with afternoon high temperatures returning to the mid 90s to around 100 degrees across the region. Additionally, heat index values will range from around 105 to 110 and should prompt at least a more widespread Heat Advisory across the region. Wednesday and Thursday will be slightly warmer than Tuesday, with highs ranging more from the mid 90s to lower 100s and heat index values once again reaching dangerous levels. Honestly, it looks like the rest of next week is going to be hot and miserable with temperatures ranging from the mid 90s to lower 100s and heat products likely into next weekend. There is some potential for showers and thunderstorms later in the week for portions of the area, but confidence is not super high at this time, and should anything develop, QPF amounts look to be on the lower side. /33/ && .AVIATION... (12Z TAFS) Issued at 640 AM CDT Sun Aug 11 2024 A large complex of showers and thunderstorms is moving east- southeast through Central and Eastern Oklahoma at the start of the period. The southern flank of this convection will likely affect Southeast Oklahoma and portions of Northeast Texas and Southwest Arkansas. Model guidance has been consistent in weakening the convection as it moves into our area later this morning. However, the models have also not been handling this complex well. Thus, the forecast is very uncertain. Given the poor model performance, VCTS was inserted for KTXK between 11/18z and 11/22z. Current thinking is the precip will not affect the other TAF sites. Otherwise, VFR conditions are expected to prevail with increasing mid and high-level cloud cover. CN && .PRELIMINARY POINT TEMPS/POPS...
