Trajectory weather: The air mass trajectories from the Edwards Plateau Texas mainly move to the east. The trajectories show good characteristics for entrainment and travel. Conditions at the source areas on the Plateau are cold this morning which will limit pollen release to the afternoon hours. Chances of rain will also decrease the possibility of pollen release. Friday's trajectories continue to move to the east. Trajectory characteristics show moderate characteristics for entrainment and travel. Conditions at the source areas will be cold again on Friday morning limiting pollen release to the afternoon hours.


OUTLOOK: *** Moderate threat *** Cold morning temperatures and chance of rain will limit pollen release.
