011 FXUS64 KSHV 131757 AAA AFDSHV Area Forecast Discussion...UPDATED National Weather Service Shreveport LA 1257 PM CDT Sun Jul 13 2025 ...New AVIATION... .KEY MESSAGES... Issued at 1127 PM CDT Sat Jul 12 2025 - Scattered to numerous showers and thunderstorms with heavy rain possible across the Four State Region today. - More in the way of scattered convection on Monday before rain chances dwindle as the work week continues. - With lower rain chances during the week, temperatures should begin to warm with near Heat Advisory criteria possible later this week. && .DISCUSSION... Issued at 1058 AM CDT Sun Jul 13 2025 An upper-level trough with embedded closed low across eastern Oklahoma into Texas to linger through Monday night allowing for increased instability resulting in periods of mainly diurnally driven convection today through Monday evening. Locally heavy rainfall can be expected with some storms today, especially in the vicinity of the upper-trough across southeast Oklahoma and northeast Texas. Stronger convection to gradually diminish during the evening hours with scattered lingering showers and embedded thunderstorms possibly continuing through the early morning hours. Overnight lows are forecast to average in the lower 70s. Similar conditions expected again on Monday as upper-low remains parked across Oklahoma and northeast Texas. Scattered diurnally driven afternoon showers expected with conditions again improving in the evening as the upper-low begins to shift northeast into Missouri, marking the beginning of an overall pattern shift across the ArkLaTex. Temperatures on Monday are forecast to range from the mid 80s across southeast Oklahoma where best rain chances are expected to the the mid 90s across north Louisiana where subsidence from an upper-ridge building west will become more influential. Upper-ridge to become established across the region on Tuesday and Wednesday allowing for more typical July hot and dry conditions areawide. Some locations across the ArkLaTex could expect highs in the upper 90s by Wednesday afternoon with afternoon heat index values 105 to 107 degrees across much of north Louisiana. Models are coming into agreement in bringing an easterly wave across the northern gulf coast late in the work week allowing for increased rain chances across mainly portions of Louisiana and south Arkansas continuing into the weekend. && .AVIATION... (18Z TAFS) Issued at 1257 PM CDT Sun Jul 13 2025 VFR conditions will continue through the afternoon and much of the evening/overnight hours, although scattered convection will again develop this afternoon over E TX, and spread NE into SW AR/NW LA, and could produce MVFR cigs, wind gusts near/in excess of 35kts, and reduced vsbys. Have inserted tempo thunder mention for all terminals this afternoon, with the convection possibly persisting through mid to late evening before diminishing. While much of the cu field will diminish after sunset, elevated convective debris will linger through a good portion of the evening/overnight hours, with the potential for additional scattered convection redevelopment possible after 08Z across portions of NE TX/SE OK/adjacent sections of SW AR, which may linger through much of the remainder of the morning. Have added VCSH mention to the TYR/GGG/TXK terminals to account for this potential, with low MVFR/IFR cigs again developing after 09Z over E TX/portions of N LA, which will spread N into SE OK/adjacent sections of SW AR by/after 12Z. These cigs will slowly lift by mid/late morning, with VFR conditions returning by the end of the TAF period. Should again see an increase in scattered convection across the region during the afternoon Monday. SSW winds 7-11kts this afternoon, except strong/gusty in and near the convection, will become S 5kts or less after 00Z. /15/ && .SPOTTER INFORMATION STATEMENT... Issued at 1257 PM CDT Sun Jul 13 2025 Spotter activation may be needed this afternoon and early evening across portions of East Texas, Southwest Arkansas, and North Louisiana for the potential for damaging winds and heavy rainfall, which may result in localized flooding. /15/ && .PRELIMINARY POINT TEMPS/POPS...
