Today
Concentration of pollen grains in the air for Wednesday will be falling into the very low range. The cause for the falling pollen levels is rising humidity, strong winds and heavy rains in the evening which tend to wash pollen out of the air.
Outlook
Based on past pollen counts and expected weather conditions, pollen levels for Thursday will be on the increase in the moderate range. This increase is due to higher temperatures and the lower dewpoint. The increase of this magnitude could make it more difficult for those with allergies.
