OUTLOOK: *** Low Threat today and Low Threat Tomorrow *** conditions have been judged to be low for pollen release, entrainment and travel because we are at the end of the pollination season for Juniperus asheii. Pollen counts from areas across the Edwards Plateau indicate that the trees have expended most of their pollen and thus there will not be much in the atmosphere no matter what the conditions are. The highest pollen levels appear to have been just before the end of January. The recent series of really cold weather fronts may have caused un-ripened cones to be lost from the trees. Either way the amount of pollen in the atmosphere has declined rapidly over the last week to 10 days. We appreciate all of feedback that we get while doing these forecasts and hope that they, in some way, help you to manage your allergies. We will begin our forecasting again next fall between Thanksgiving and early December.
