488 FXUS64 KSHV 121754 AAA AFDSHV Area Forecast Discussion...UPDATED National Weather Service Shreveport LA 1254 PM CDT Sat Jul 12 2025 ...New AVIATION... .KEY MESSAGES... Issued at 1057 PM CDT Fri Jul 11 2025 - An uptick in convective coverage is expected this afternoon and evening across the Four State Region and that will likely continue into Sunday as well. - Rain chances diminish through midweek. - An easterly wave in the gulf could introduce uncertainty in regards to temps and rain chances late in the workweek. && .DISCUSSION... Issued at 1146 AM CDT Sat Jul 12 2025 An upper-level trough across the Red River Valley of north Texas will bring scattered convection to the the ArkLaTex this afternoon into this evening. Some strong storms with gusty winds, small hail, and locally heavy rainfall may be possible across mainly the I-30 corridor. Elsewhere, most convection this afternoon into this evening will be diurnally generated as temperatures climb into the low to mid 90s with possible seabreeze forcing. With the upper-trough remaining nearly stationary through the weekend into early next week across the Red River Valley, increased instability to continue across the I-30 corridor. Model discrepancies have led to uncertainty regarding timing and placement of periodic mesoscale convective clusters supportive of heavy rainfall. Due to the dynamically shifting model trends regarding timing of convection, went ahead and incorporated a generalized wet bias across these areas through early next week. Pattern begins to shift through the upcoming workweek as as an upper-ridge to the east retrogrades west across the ArkLaTex. Rain chances to diminish significantly from Tuesday into Wednesday with subsidence from the ridge to drive afternoon temperatures into the upper 90s to near 100 degrees. Uncertainty creeps back into the forecast late in the workweek as models are beginning to diverge over a disturbance in the Gulf of America that may bring unsettled weather to the ArkLaTex on Thursday into Friday. Should the ridge instead hold across the ArkLaTex, hotter and drier conditions to prevail. Will have to wait for later model runs to offer more certainty regarding the the long-term forecast period. 05 && .AVIATION... (18Z TAFS) Issued at 1254 PM CDT Sat Jul 12 2025 VFR conditions will continue this afternoon through a portion of tonight, although scattered convection has developed early this afternoon across the region, which may result in localized areas of MVFR cigs and reduced vsbys in/near the convection. Have inserted VCTS for much of the afternoon/early evening for all terminals, with tempo thunder mention for locally gusty winds near/in excess of 30kts, reduced vsbys, and the lower cigs. The convection should mostly diminish by mid-evening, but may persist through the remainder of the evening into the overnight hours over portions of extreme NE TX/SE OK/adjacent SW AR, primarily NNW of the TYR/GGG/TXK terminals. While the residual convective debris should diminish by late evening, low MVFR cigs should again develop after 09Z Sunday over much of E TX/SE OK/adjacent SW AR/NW LA, and spread NNE across the remainder of the area after daybreak. These cigs should slowly lift by mid to late morning, with VFR cigs returning by the end of the TAF period. Additional scattered convection should again develop over much of the area Sunday afternoon. SSW winds 8-12kts with higher gusts in/near the convection, will become S 3-7kts after 00Z. /15/ && .SPOTTER INFORMATION STATEMENT... Issued at 1254 PM CDT Sat Jul 12 2025 Spotter activation is not likely today through tonight as widespread damaging wind gusts are not forecast. However, isolated severe thunderstorms will be possible this afternoon and evening which could produce damaging wind gusts and heavy rainfall that could result in localized flooding. /15/ && .PRELIMINARY POINT TEMPS/POPS...
