Trajectory confidence: High
OUTLOOK: *** Mild Threat *** Mixed conditions for pollen release today. Temperatures are in the tolerance range.....but humidities are still high and changing very little at the late morning hours.Low levels of pollen release expected today and those should come mostly from the western sections of the Plateau, where humidities are most likely to become favorable this afternoon. Any airborne spores are likely to be drawn upward into the developing low pressure system (note graph of vertical motion below the main map) after little movement this afternoon and evening. Thus, effects on the population should be limited. Residents of the Edwards Plateau region....and western North Texas may have small amounts of pollen moving through their areas this afternoon and tonight. Low Threat of pollen release on Friday with high humidities and a chance of rain. TK
