Any precipitation will be rain in the south, but there is a chance of snow or rain/snow mix in north Texas and Oklahoma.

 

Trajectory weather: The air mass trajectories show little movement early this afternoon then turn north and move over north Texas and Oklahoma as the winds shift to southeasterly. Conditions at the sources today will be in the 50s and dry with clear sunny skies. Tomorrow skies will be partly cloudy with temperatures warming to the 50s again after a cold night. Trajectories tomorrow move north into Oklahoma then turn east across Oklahoma and Arkansas.
