.AVIATION... (12Z TAFS) Issued at 727 AM CDT Wed Sep 24 2025
For the 24/12 TAF period...A line of showers and thunderstorms developed across SW Arkansas overnight ahead of a cool front and is currently located at the Louisiana border. Ahead of it, isolated to scattered showers have developed closer to the I-20 corridor. We should see more convection develop during the mid to late morning hours and gradually shift southward along the slow moving cool front. This will bring reduced flight categories to our sites. Winds will shift to the north behind the front, with skies gradually lifting towards the end of the period. /20/
