Pollen Forecast for Happy Valley, Oregon

Today
Concentration of pollen grains in the air for Monday will be falling in the low range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to falling temperatures, rising humidity, and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air. That's good news for allergy sufferers.
Outlook
Concentration of pollen grains in the air for Tuesday will be greater than today's levels in the moderate range. This results in part from 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.
