Pollen Forecast for Van Orin, Illinois

Concentration of pollen grains in the air for Friday will be falling in the moderate range. This relief in pollen levels is caused in part by rising humidity, weak winds and expected precipitation in the morning and afternoon which tends to wash pollen out of the air.

Pollen concentrations for Saturday will be greater than today's levels in the moderate range. Since the weather has a major influence on pollen dispersal, this increase is due in part to higher temperatures and the lower dewpoint.
