Pollen Forecast for Mount Zion, Illinois

Based on past pollen counts and expected weather conditions, pollen levels for Friday will be higher than they were today in the moderate range. The cause for the rising pollen levels is rising temperatures, strong winds and lower relative humidity.

Concentration of pollen grains in the air for Saturday will be falling in the moderate range. This relief in pollen levels is caused in part by falling temperatures and heavy rains in the morning and evening which tend to wash pollen out of the air. That's good news for allergy sufferers.
