Most airborne pollen will be moving slowly eastward across central Texas through Sunday evening. Pollen released from eastern sections of the Plateau will flow north and then east.....afftecting residents of east-central Texas today (Waco), northeast Texas tonight (Dallas/Ft.Worth, Sulfur Springs), and southern Arkansas on Sunday. Washout of airborne pollen should occur sometime Sunday. For Sunday's release.....similar conditions will prevail with more significant release expected. Winds will take the airborne pollen to the south and east through Monday morning. Affected areas include the Texas hill country....south-central Texas....the Texas coastal bend....and the Rio Grande Plains. TK
