OUTLOOK: *** Moderate Threat *** Conditions are mixed for pollen release today. Temperatures are favorable. Humidities have been dropping slowly through the high values during the morning, but it appears that they will not make it to the tolerance zone during the afternoon. Winds are pretty favorable, consistently over 10mph. Despite the high humidities, some release is expected. Residents of southern and southeast OK are the mostly likely to be affected from today's release. Those persons living near the TX/AR or the TX/LA border may also feel some ill effects tonight or Thursday. TK
