106 FXUS64 KSHV 240034 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 734 PM CDT Sat Aug 23 2025 ...New AVIATION... .KEY MESSAGES... Issued at 1243 PM CDT Sat Aug 23 2025 - Very isolated showers will be possible across southern portions of deep east Texas this afternoon and evening, dissipating quickly - This weekend will otherwise remain mostly dry, while temperatures warm back into the middle to upper 90s - Next week is shaping up to be more unsettled, with daily showers and storms beginning late Monday into Tuesday, as well as below average high temperatures. && .DISCUSSION... Issued at 1243 PM CDT Sat Aug 23 2025 A weak 700mb trough is responsible for increasing cloud cover over the heart of the ArkLaTex by this midday hour. Widespread showers and storms are not anticipated, but a few short range high res models suggest very isolated light showers will be possible across east Texas, largely south of the I-20 corridor. Anything that does develop will most likely dissipate equally quickly, diminishing completely after sunset. Overnight, temperatures are expected to drop into the upper 60s northeast and lower 70s southwest. Sunday looks to be be another warm, dry and quiet one, as temperatures aim for the mid to upper 90s, and this warm trend potentially continuing into early next week for the southern half of the region. The hint of relief will be that the drier airmass in the wake of the frontal passage should keep humidity in check, and it is not looking like it should be necessary to issue any heat products. Long range guidance continues to depict the next significant upper level system advancing southward on northwest flow early in the week swinging another front into the ArkLaTex. As of this writing, only our southeast Oklahoma zones look to expect much, if any, storms on Monday, with the more substantial push arriving overnight and continuing into the day Tuesday. The Excessive Rainfall Outlook continues to highlight northern portions of the ArkLaTex for the possibility of flash flooding on Tuesday. Rainfall chances trend down Wednesday then pick up again Thursday as the next northwest flow system sweeps into the area. Aside from short-lived breaks in the weather, rainfall chances continue for much of the week ahead. This will moderate temperatures considerably, with highs in the upper 80s to lower 90s, making for a cooler-than-average last week of August for the Four State Region. /26/ && .AVIATION... (00Z TAFS) Issued at 636 PM CDT Sat Aug 23 2025 For the 24/00Z TAF update, VFR conditions are expected through the period with a typical diurnal cycle of cumulus fields and brief, isolated chances of -SHRA/VCTS. Surface winds will pick up from the northwest from 24/18Z through the end of the period. /16/ && .SPOTTER INFORMATION STATEMENT...
