Today
The quantity of pollen grains in the air for Wednesday will be falling into the extremely low range. This decrease is due to falling temperatures, rising humidity, and heavy rains in the afternoon which tend to wash pollen out of the air.
Outlook
The amount of pollen in the air for Thursday will be higher than they were today in the moderate range. Since the weather has a major influence on pollen dispersal, this increase is due in part to higher temperatures and the lower dewpoint. If you do suffer from allergies tomorrow could be more difficult.
