Pollen Forecast for Macomb, Illinois

Pollen concentrations for Friday will be on the increase but will stay in the very low range. Since the weather has a major influence on pollen dispersal, this increase is due in part to higher temperatures and the lower dewpoint.

The quantity of pollen grains in the air for Saturday will be falling and will remain in the extremely low range. This relief in pollen levels is caused in part by rising humidity, weak winds and expected precipitation in the evening which tends to wash pollen out of the air.
