Pollen Forecast for Ashburn, Virginia

The pollen levels for Thursday will remain relatively stable in the very high range. This is a result of stable temperatures. The pollen producing plants are delivering a fairly constant level of pollen into the air.

The quantity of pollen grains in the air for Friday will be falling but will remain in the high range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to falling temperatures, rising humidity, and expected precipitation in the afternoon and evening which tends to wash pollen out of the air. Relief is in sight.
