Based on past pollen counts and expected weather conditions, pollen levels for Wednesday will be falling in the moderate range. This change results in part from falling temperatures, rising humidity, and expected precipitation in the afternoon which tends to wash pollen out of the air.
Pollen concentrations for Thursday will be rising in the moderate range. This higher level is caused in part by seasonally normal weather conditions which are favorable for the production and dispersal of pollen.
