OUTLOOK: *** Moderate Threat *** Mixed conditions for pollen release today. Humidities are a bit high in the east, and temperatures are still below favorable values at 11 am local time. Conditions are moving toward more favorable values for release, however. Pollen release is likely for at least several hours this afternoon. Initial movement this evening and tonight is to the south. Residents of south-central Texas......the Texas coastal bend...and the Rio Grande Plains.....including the cities of Del Rio, San Antonio, and Corpus Christi....may feel some ill effects from today's release. Most of the airborne pollen will turn to the north on Friday and move toward central and eastern Texas. TK
