Trajectory weather: Mostly clear through the forecast. Highs today in the 50's. Lows tonight 20's north, near 40 south TX. Highs Wednesday 50's north, low 60's south TX.
Trajectory confidence: High
OUTLOOK: *** Mild Threat *** Mostly unfavorable conditions for pollen release. Humidities are favorable but temperatures are having a hard time getting into the favorable ranges, especially for western sections. Winds are moderate and variable. Little release expected, with those persons living in south-central TX the most likely to feel any ill effects. *** Recent reports from the Edward's Plateau are mixed with regard to pollen availability. According to Dr. Jack Kent in Austin, there is little to no pollen on the trees in the area. Yet, he reports allergic symptoms, indicating some pollen is in the air. Information from Bill Durbon in Junction describes relatively low pollen levels at this time, with no profuse pollination to report. Trees have appeared ready to pop for several weeks but have yet to do so. *** Given the past and continuing dry weather, it appears that pollen production is, in general, comparatively less this year and likely spotty in nature. We will continue to update you on the situation as we receive more information. *** TK
