Trajectory confidence: High
OUTLOOK: *** Low to Moderate Threat *** Now that we are nearing the end of the season, decreasing amounts of airborne pollen are expected. Mixed conditions for pollen release today.....better towards the eastern end of the Plateau as opposed to the more usual western sections. Some light rain is falling in the western sections and its much cooler so little release is expected from that area. Moderate release expected from the eastern side. Airborne pollen will be moving through southeast Texas and the upper Texas coast this afternoon and evening.....and along the Louisiana coastal area tonight. On Saturday.....a Mild to Moderate release event is anticipated. Airborne pollen will move initially south, then turn to the north, affecting central and northern Texas Saturday night into Sunday. TK
