844 FXUS64 KSHV 101655 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 1155 AM CDT Sat Aug 10 2024 ...New UPDATE, SHORT TERM... .UPDATE... Issued at 1122 AM CDT Sat Aug 10 2024 Tweaked a few high temps and added cu field to grids. && .SHORT TERM... (This afternoon through Sunday) Issued at 1122 AM CDT Sat Aug 10 2024 Dew points are set to fall with the backdoor push of low to mid 60s arriving. The temps are warming quickly, but are slowing the pace now with decent wind across the region. At 11am, a large range of low to upper 80s were reported across our Four-States. A 1024mb high over the middle MS River Valley is our dominant player and will remain so through Sunday. A few high temps needed tweaking for the graphics to match, but overall no changes to prelim numbers from the original a.m. issuance. Zones updated mainly for sky and new graphics too soon. /24/ && .LONG TERM... (Sunday Night through Saturday) Issued at 339 AM CDT Sat Aug 10 2024 The upper level ridge will slowly migrate eastward and become centered over North Texas and the ArkLaTex by late Tuesday. In addition, the region will gradually strengthen. A weak upper disturbance rotating around the ridge could bring some slight chances for rain to portions of McCurtain County early Monday, and southerly surface winds may allow for very isolated sea breeze convection in our southern zones Tuesday afternoon. However, the building ridge and strengthening subsidence will generally result in diminishing rain chances. The prolonged dryness that much of the area is experiencing will likely continue through at least Friday. In addition, the ridge will also bring oppressive heat back to the region. Daytime high temperatures will quickly warm after Sunday and most locations will climb into the upper 90s to lower 100s for the entire work week. After Monday, peak heat index values will also likely be above 105 degrees areawide through Friday, which will necessitate Heat Advisories. Heat indices may also approach or exceed 110 degrees in some locations, especially Wednesday through Friday. CN && .AVIATION... (12Z TAFS) Issued at 611 AM CDT Sat Aug 10 2024 For the 10/12z TAF update...Satellite imagery continues to show some clouds moving into the region from the northwest this morning. Surface observations across southeast Oklahoma and southwest Arkansas are showing SCT to BKN clouds around 4k feet. For this reason, and also for the expectation of some afternoon cu development, have mention of some low end VFR CIGs for all terminals later this morning and into the afternoon hours. Otherwise, winds will be light and generally out of the north to northeast. /33/ && .PRELIMINARY POINT TEMPS/POPS...
