Issued at 1245 PM CDT Sat Jul 26 2025 Showers and thunderstorms are ongoing across the Four State Region this afternoon as a surge of Gulf moisture works through. Though much of the accumulation values to this point have been marginal, there have been instances of a quick inch or more as a stronger storm cluster advanced through west central and northwest Louisiana. Scattered convective coverage is expected to continue into the late afternoon, with potential that a few stray showers carry over into the early evening. That being said, much of the overnight should remain dry as rain chances will be on the decline through Sunday. The unfortunate side to a decline in rain opportunity is that as the faucet turns off, the temperature rises with heat headlines returning as early as tomorrow afternoon. Another Heat Advisory has been issued for much of the Four State Region for Sunday as heat indices will climb between 105-109 deg F. MaxT`s will also be on the climb with afternoon highs in the mid and upper 90`s. As mentioned, rain chances will be on the lower end tomorrow afternoon, but non-zero with focus primarily across the far southern zones as the Gulf sea breeze advances north around lunchtime. How strong the boundary is will dictate if rain chances get to the I-20 corridor. For now, not ruling out a stray shower or two near the SHV/BC metro, but highest confidence remains around the Toledo Bend vicinity. Beyond Sunday, heat headlines will become the main focus as upper ridging retrogrades from the SE CONUS and settles over the FA. The influence of the strong ridge regime will allow for afternoon highs to flirt with the triple digits through mid-week while heat indices hold advisory criteria, if not even begin to enter warning criteria (at or above 110 deg F). This threshold will need to be monitored closely in the coming days as present heat products may need to be upgraded. Much of this will depend on how much dew point temperatures mix out through the afternoon. Bottom line is, the heat returns, and following heat safety protocol will be important. The good news in all of this is, is that marginal rain chances return to portions of the region as early as Wednesday afternoon, with increasing odds through Thursday. KNAPP && .AVIATION... (00Z TAFS) Issued at 706 PM CDT Sat Jul 26 2025 VFR conditions will continue this evening through the overnight hours into Sunday morning. Isolated convection will linger near ELD/MLU through 01Z this evening before diminishing, although elevated cigs from the earlier convection should persist overnight across the region. Some IFR/low MVFR cigs may develop by/shortly before daybreak Sunday over portions of Deep E TX and N LA, before eventually lifting/scattering out by mid to late morning. A scattered cu field will develop by late morning and persist through the afternoon, although a weak seabreeze may move inland from the SE TX/SW LA coast and could possible affect LFK after 20Z, before diminishing by the end of the TAF period. However, low confidence precludes VCTS mention at the LFK terminal attm, and will re-evaluate for the 06Z TAF issuance. S winds 5-9kts tonight will become more SSW after 15Z. /15/ && .SPOTTER INFORMATION STATEMENT...
