Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the east, southeast over southeastern Oklahoma and east Texas. The trajectories are associated with cold sinking air and show poor characteristics for entrainment and travel. Conditions at the source are cold this morning but will warm to the favorable range by early afternoon. Trajectories on Wednesday begin moving to the south then turn to southwest and show poor to moderate characteristics for entrainment and travel. Conditions at the source will again be cold in the morning and only reaching the favorable range in the afternoon.

OUTLOOK: *** Low to moderate threat *** Low morning temperatures will limit pollen release to afternoon hours today and tomorrow.
