Pollen Forecast for Grass Valley, Oregon
Today
Based on past pollen counts and expected weather conditions, pollen levels for Sunday will be falling and will remain in the very low range. This change results in part from rising humidity, weak winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air.
Outlook
The pollen levels for Monday will be rising but will still remain in the low range. This increase is due to higher temperatures and the lower dewpoint. This heavy increase in pollen concentration could very well cause problems for those who are allergic to airborne pollens.
