Pollen Forecast for Coralville, Iowa

The quantity of pollen grains in the air for Monday will remain relatively stable in the high range. No change doesn't mean no pollen, it just means that pollen producing plants are delivering pollen at a steady pace.

The pollen levels for Tuesday will be falling but will remain in the high range. This forecast of lower pollen concentration is based on rising humidity, weak winds and expected precipitation in the afternoon and evening which tends to wash pollen out of the air.
