Winds on the Plateau will remain moderate, coming from a northerly direction, while those in the surrounding communities will remain moderate from the south.


Trajectory weather: The air mass trajectories from the Edwards Plateau move to the north, northeast this afternoon over central Texas and eastern Oklahoma. Clear skies today, with very warm conditions will occur in across Texas including the source areas on the Plateau. Winds will be moderate to strong and from the south, southwest. Conditions in the tree population on the Edwards Plateau will be good for pollen release today and tomorrow because of warm sunny conditions and moderate to strong winds. Buoyant atmospheric conditions will result in moderately good conditions for travel of pollen entrained in the atmosphere.


OUTLOOK: *** High Threat *** very favorable conditions for pollen release along with moderately good conditions for entrainment and transport. Warm conditions with moderate to strong winds will present favorable conditions for pollen release, and moderately good conditions for entrainment and travel. Winds today will be initially from the south today, tonight, and tomorrow.
