Pollen Forecast for Trail, Oregon

The pollen levels for Thursday will be falling into the extremely low range. This lower level is caused by falling temperatures, lack of strong winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air.

The quantity of pollen grains in the air for Friday will be greater than today's levels in the moderate range. This rise is a result of seasonally normal weather conditions which are favorable for the production and dispersal of pollen. If you have these allergies, tomorrow will likely be more difficult outdoors.
