Pollen Forecast for West Salem, Illinois

The pollen levels for Friday will be increasing over today's levels and extend further into the very high range. This rise is a result of rising temperatures, strong winds and lower relative humidity. These overall conditions could make it a bit more difficult for those who are allergic to airborne pollens.

The quantity of pollen grains in the air for Saturday will be falling in the moderate range. This forecast of lower pollen concentration is based on rising humidity and heavy rains in the evening which tend to wash pollen out of the air. Relief is in sight.
