859 FXUS64 KSHV 141749 AAA AFDSHV Area Forecast Discussion...UPDATED National Weather Service Shreveport LA 1249 PM CDT Wed Aug 14 2024 ...New AVIATION... .UPDATE... Issued at 1021 AM CDT Wed Aug 14 2024 As of the 15Z hour, temperatures are near or even slightly below where we were sitting at this time yesterday. Dewpoints continue their stubborn trend of only gradually mixing out, causing sites across the ArkLaTex to be reaching Heat Advisory criteria (heat indices of 105 or greater) momentarily, if not already. Ultimately, taking conditions thus far this morning fully into account, no changes appear necessary to the overnight forecast package. We will see daytime highs climb into the upper 90s to near or just above the century mark areawide, with the lone exception of some more elevated sites along the I-30 corridor into Arkansas who have seen more rain cooling effects recently, and may "only" reach the middle 90s this afternoon. /26/ && .AVIATION... (18Z TAFS) Issued at 1249 PM CDT Wed Aug 14 2024 VFR conditions will continue through the 14/18Z TAF period. A scattered cu field has developed this afternoon areawide, with isolated convection possible across portions of SCntrl AR and NE LA. However, low confidence precludes VCTS mention at the MLU/ELD terminals attm, and will amend as needed. The cu field should diminish shortly after sunset, but some residual convective debris may linger overnight across Srn AR/NCntrl LA before eventually thinning. Another scattered cu field should begin to develop by late morning Thursday, with any isolated afternoon mainly confined to NE LA and especially much of MS. SSW winds 5-8kts this afternoon will become light S/Lt and Vrb after 00Z. /15/ && .PRELIMINARY POINT TEMPS/POPS...
