Temperatures will warm by a degree or so each day into the start of the work week. - Precipitation chances will remain low through the weekend, then increase early next week with the potential of isolated to scattered storms to develop each afternoon through the middle of the week. - Heat Indices in the upper 90s to lower 100s can be expected today thru Tuesday. Practice heat safety! Hydrate, take breaks and stick to the shade. && .DISCUSSION... (Tonight through next Saturday) Issued at 1155 PM CDT Sat May 30 2026 Aloft, weak zonal flow has slowly transitioned into upper-level ridging. At the surface, high pressure in the western Atlantic will keep our background winds from the south. For Sunday, conditions will be sunny and mostly dry, with high temperatures in the 90s. In the afternoon, we should see a few diurnally driven showers and thunderstorms. As we move into the work week, afternoon showers and thunderstorms will be more widespread along with the addition of some seabreeze effects. This forecast will repeat for most of the week as weak ridging aloft will keep skies mostly clear, and temperatures will slowly climbat least for the first half of the week. While we are not close to heat advisory levels, we are looking at apparent temperatures breaking into the triple digits across much of central Louisiana and the interior of southeast Texas. If you are working outside or starting practice, make sure to take plenty of breaks and stay hydrated! For the second half of the week, the upper-level ridge will start to break, leading to more widespread convection and cloud cover. This will lead to temperatures dropping back into the upper 80s. While not a huge relief from the heat, we will take anything we can as we start the dog days of summer. && .AVIATION... (12Z TAFS) Issued at 614 AM CDT Sun May 31 2026 VFR conditions and light southerly winds around 5-10 kt prevail at all sites throughout the valid TAF period. Guidance does advertise low probabilities of light fog/mist at LFT and ARA after 01/09Z, but uncertainty is high so have left this out of the forecast at this time. 64/Silas && .MARINE... Issued at 1155 PM CDT Sat May 30 2026 High pressure in the western Gulf will cause prevailing south winds around 10 to 15 knots. Wave heights will stay below 3 feet through the middle of the week. Pop-up showers and thunderstorms will be possible but will mainly be limited to near-shore waters. && .FIRE WEATHER... Issued at 1155 PM CDT Sat May 30 2026 With high pressure driving our weather pattern, we will start to dry out with rain coming in the form of pop-up showers and thunderstorms. Even with the ridging aloft, persistent southern flow will keep minimum RH values around 50%. Due to the recent rainfall, fuels are green with KBDI values between 100 and 200. && .LCH WATCHES/WARNINGS/ADVISORIES... LA...None. TX...None. GM...None. && $$ PUBLIC/FIRE/MARINE...14 AVIATION...64
