Pollen Forecast for Asotin, Washington

The amount of pollen in the air for Thursday will be increasing but will stay in the very low range. This results in part from higher temperatures and the lower dewpoint.

Pollen concentrations for Friday 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 afternoon and evening which tends to wash pollen out of the air.
