(This evening through next Thursday) Issued at 1217 PM CDT Fri Aug 28 2026 The region remains situated between a persistent upper level ridge centered over the four corners region and troughing extending across much of the eastern U.S. The northerly flow aloft will continue to filter in some drier air aloft which will keep precipitation chances to a minimum this afternoon although a few spotty showers may still develop. Any showers that manage to get going will dissipate by around sunset this evening. The upper ridge will build east into the area Saturday further limiting both convection and cloud cover which will, in turn, push afternoon highs into the mid to upper 90s. Fortunately, some of the drier air aloft is expected to mix down to the surface during the afternoon especially across central Louisiana with dewpoints falling into the mid 60s to lower 70s. This is expected keep the area below heat advisory criteria despite the higher temperatures. Similar conditions are expected for Sunday across most of the region. Guidance has been in consistent agreement on moving an inverted trough/tropical wave from east to west across the northern gulf coast through the weekend and the significant moisture associated with it will be moving into southeast and south central Louisiana Sunday afternoon creating a sharp precipitation gradient across the Atchafalaya basin. This wave will slowly meander west across the area Monday through Wednesday offering notably higher precipitation chances through the first half of next week. While this feature will offer some modest relief for the ongoing drought, it`s not expected to be a drought busting event. Jones && .AVIATION...

By Monday, an inverted trough/tropical wave will move from east to west across the northern gulf coast providing elevated precipitation chances Monday through Wednesday. Away from storms, light southerly winds will prevail today through late next week. && .FIRE WEATHER... Issued at 1217 PM CDT Fri Aug 28 2026 Lower precipitation chances are expected today through the weekend with chances climbing again early next week as a disturbance moves from east to west across the northern gulf coast. Slightly drier air will filter down into the region later tonight into Saturday, allowing MinRH values to fall into the 35 to 45% range across interior SE TX/CENLA both Saturday and Sunday afternoons. RH`s will increase again area-wide Monday with MinRH values back in the 50 to 60% range areawide.
