Pollen Forecast for Olney, Illinois

The quantity of pollen grains in the air for Saturday will be higher than they were today 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 seasonally normal weather conditions which are favorable for the production and dispersal of pollen.

Based on past pollen counts and expected weather conditions, pollen levels for Sunday will be increasing but will still remain in the low range. The cause for the rising pollen levels is higher temperatures and the lower dewpoint.
