Today
Pollen concentrations for Sunday will be falling in the moderate range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to falling temperatures, higher dew points and lack of strong winds.
Outlook
Pollen concentrations for Monday will be at about the same level in the moderate range. If you do suffer from allergies, tomorrow should be about as difficult outdoors as it was today.
