Today
Based on past pollen counts and expected weather conditions, pollen levels for Saturday will be rising in the high range. Since the weather has a major influence on pollen dispersal, this increase is due in part to rising temperatures, strong winds and lower relative humidity. This heavy increase in pollen concentration could very well cause problems for those who are allergic to airborne pollens.
Outlook
The amount of pollen in the air for Sunday will be falling but will remain in the high range. This change results in part from rising relative humidity and relatively weaker winds.
