.AVIATION...
(06Z TAFS)
Issued at 1040 PM CDT Sat Aug 16 2025

Prevailing VFR conditions remain forecast at all terminals
through the period. Besides the return of breezy southerly winds
and a continued mix of occasional low/high-level cigs, widely
scattered convection remains the focus on Sunday. While most
terminals will have limited/nil impact, have added PROB30 mentions
at western Oklahoma and north Texas terminals given a more
focused signal in late-evening guidance of this potential. Gusty
winds and brief vis reductions would be possible beneath
thunderstorms.

Safe travels!
