335 FXUS64 KSHV 082040 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 340 PM CDT Wed May 8 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Thursday Night) Issued at 339 PM CDT Wed May 8 2024 Active weather will continue across the Four State Region through the rest of the week. A slow-moving frontal boundary will keep the atmosphere disturbed (and environmentally conducive) enough to instigate multiple rounds of severe weather in the next 48 hours, including tonight and tomorrow afternoon/evening. Severe thunderstorms will produce risks predominantly for large hail and damaging winds, but a few tornadoes cannot be ruled out. As of 3:15 PM, SPC has issued downstream Tornado Watches into the ArkLaTex accordingly through 10 PM. Otherwise, temperatures will remain above average with maximums in the lower 90s/lower 70s. /16/ && .LONG TERM... (Friday through next Tuesday) Issued at 339 PM CDT Wed May 8 2024 Quieter weather briefly returns through the weekend before precipitation chances are reintroduced early next week. Quasi- zonal flow aloft will allow for a mid-level trough to drift eastward across the Four Corners into the Southern Plains. This trough, in combination with ridging shifting further east across the Mississippi River, will maintain enhanced southerly flow and moisture through most of early next week. Precipitation chances will remain through the same time period as a result. /16/ && .AVIATION... (18Z TAFS) Issued at 101 PM CDT Wed May 8 2024 High based MVFR cigs are still hanging tough attm across portions of E TX/N LA/Srn AR, but additional improvement to VFR is expected through 20Z with these low VFR cigs expected to persist through the remainder of the afternoon hours. Scattered convection is expected to develop after 23Z from portions of NCntrl TX into SE OK along a weak cold front, with this convection quickly spreading into NE TX/SW AR by early to mid evening. Have maintained VCTS for all but the LFK/MLU terminals from mid-evening through shortly after 06Z, with the convection expected to weaken shortly after 06Z as its remnants progress ESE across N LA. VCTS may be needed in later TAF issuances for MLU, although its conceivable that mesoscale bndrys from this convection will move through MLU and delay the development of MVFR cigs until late. Elsewhere, low MVFR cigs are expected to develop by 05Z across Deep E TX/portions of N LA, but its expansion Nwd may be delayed by any mesoscale bndrys produced from the evening convection. IFR/LIFR cigs should develop though at LFK late tonight, with any remaining areas affected by the earlier convection expected to see low cig development after 12Z. Slow improvement should occur to cigs by mid to late morning, although VFR cigs will likely not return until the end of the 18Z TAF period or beyond. S winds 9-13kts with occasional gusts to 20kts this afternoon, will diminish to 5-10kts after 00Z. /15/ && .PRELIMINARY POINT TEMPS/POPS...
