Pollen Forecast for Garrison, Illinois
Today
The pollen levels for Monday will be falling into the extremely low range. The cause for the falling pollen levels is falling temperatures and heavy rains in the morning and evening which tend to wash pollen out of the air.
Outlook
Concentration of pollen grains in the air for Tuesday will be unchanged in the extremely low range. Because pollen is produced by growing and blooming plants, no such plants means no local pollen.
