351 FXUS64 KSHV 271811 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 111 PM CDT Thu Jun 27 2024 ...New AVIATION... .UPDATE... Issued at 926 AM CDT Thu Jun 27 2024 Surface analysis this morning advertises a weak frontal boundary pushing through the I-20 corridor, likely stalling south of KSHV over the next hour or so. The advancement of the boundary, and better thermodynamic parameters across the SW zones, has supported scattered showers near and around KLFK, moving SE. Little to no lightning associated with the reflectivity returns, but have maintained PoPs in the region through the afternoon given diurnal heating and forcing from the boundary. Aside from this, forecast continues to be on track with the only adjustment needed was to correct hourlies to match latest trends as broken skies have resulted in quicker warming at select sites. Highs in the low to mid 90`s are still expected this afternoon. RK && .SHORT TERM... (Thursday through Friday) Issued at 406 AM CDT Thu Jun 27 2024 A weak frontal boundary, currently located near the I-20 corridor of East Texas and North Louisiana, continues to slowly push southward across the region. It has ignited a few isolated showers and thunderstorms across East Texas this morning, where the atmosphere isn`t capped. Can`t rule out some additional isolated showers or thunderstorms near the boundary today as it slowly sinks just south of the region before stalling and eventually washing out. In wake of the front, we should see some slightly cooler temps and humidity, with highs in the low to mid 90s. Therefore, no heat products will be needed, as heat index values should stay below the 105 degree threshold. Upper level ridging will start to build eastward back into the region late today into Friday. Drier conditions will return to the region, although there is a slight chance a few isolated showers or thunderstorms could form across the extreme southern sections of our Deep East Texas and adjacent Central Louisiana zones Friday afternoon near the stalled boundary. We will also see a return in warmer conditions, with highs climbing back into the mid to upper 90s. Could even see a few isolated 100 degree readings. Because of this, we will likely see a return in heat headlines. && .LONG TERM... (Friday Night through Thursday) Issued at 406 AM CDT Thu Jun 27 2024 Drier conditions will continue Saturday, as the center of the upper ridge will be over the region. Additional heat products will be likely, as afternoon highs will top out in the mid 90s to around 100 degrees. The center of the ridge will slide westward over North Texas on Sunday and Monday. Long range models are suggesting the ridge will break down enough across our region, for northwesterly flow aloft to return. This would bring convection back into the region during this period, as the flow would bring another frontal boundary into the area. However, upper ridging is expected to shift back over the region by the middle portions of next week, bringing a return of much drier conditions, and more heat headlines. However, there could be enough weakness on the southern fringe of the ridge for some slight diurnal rain chances in our Deep East Texas and adjacent Central Louisiana zones. && .AVIATION... (18Z TAFS) Issued at 1219 PM CDT Thu Jun 27 2024 For the ArkLaTex terminals, weak fropa holding over much of the area and sitting now in the KLFK vicinity. Light NE sfc winds today will veer to E and SE overnight and return from the S/SW 5-10KT for our Friday as this "toe holding" air mass quickly erodes. Aloft, we see deep N/NE flow 10-30KT for climb & all FLs. Summer returns with hot and dry conditions to start the wknd, but late Sunday, overnight and early Monday should see a return of some convection w/ a secondary backdoor fropa to start next week. /24/ && .PRELIMINARY POINT TEMPS/POPS...
