Pollen Forecast for Centreville, Illinois

The pollen levels for Sunday will be increasing over today's levels but will still remain in the low 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 Monday will be falling in the low range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to rising humidity and expected precipitation in the afternoon which tends to wash pollen out of the air.
