(Tonight through next Thursday) Issued at 1146pm CDT Thu September 17 2026

An upper ridge is centered over the Ozarks, where it will meander for the next few days before slightly weakening and shifting back over TX / the Southern Plains. This has helped suppress showers and storms, while also keeping the region generally drier and much warmer. While temperatures will be nearly 5 to 10 degrees above climatological normals for this time of year, the drier airmass will limit heat index values from reaching heat hazard criteria. Nevertheless, it will still be plenty hot, and caution will be warranted.

As the aforementioned ridge begins to weaken and shift farther west over Texas, along with a trough moving westward off the Florida Gulf Coast, we will see a gradual return of moisture and isolated Probability of Precipitation to the forecast.

The pressure gradient over the region will continue to relax, with winds and seas following suit. Thanks to drier air and high pressure aloft, chances for showers and storms will be minimal over the waters through the next few days.

Fire Weather
Issued at 1146pm CDT Thu September 17 2026

A dry airmass will move across the region through Saturday. MinRH values will fall into the 30s to mid 40s across most interior locations both Friday and Saturday afternoons. Moisture will increase once again Sunday into Monday. The latest drought map has a one class degradation across SWLA and parts of lower Acadiana. With little to no rainfall expected through the period, it will not be out of the realm of possibility to see another class degradation across our forecast area next week.
