I live in North TX not too far from you. This fall into Dec. has been odd water temperature-wise and the bass never fit into a specific pattern (at least the lakes east of Dallas) or didn't hold it for very long. They rarely (almost never) schooled up at our lake here in Athens . Even the tournament out at Lake Fork in Nov. the weights seemed well down overall (aside from the winner).
I believe the water has been continually turning over b/c of the unseasonably high temperatures - every time I think the turnover is just about done in Oct/Nov. I'd see the coffee water on our lake in Athens pop up in certain spots.
That said, I think you can now rely on specific late fall/winter patterns and target bass shallow in the afternoon on sunny days when the wind is out of the South., find the remaining vegetation, etc, and then deeper water near timber - traditional winter(ish) stuff.
Good luck!
