Pollen Forecast for Washington, Iowa

The quantity of pollen grains in the air for Wednesday will be higher than they were today in the moderate range. The cause for the rising pollen levels is drier air. If you do suffer from allergies tomorrow could be more difficult.

The amount of pollen in the air for Thursday will be falling in the low range. This relief in pollen levels is caused in part by falling temperatures, rising humidity, and expected precipitation in the morning and afternoon which tends to wash pollen out of the air.
