Pollen Forecast for Chehalis, Washington

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

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