Pollen Forecast for Hays, Montana

Concentration of pollen grains in the air for Thursday will be rising in the moderate range. This rise is a result of rising temperatures, strong winds and lower relative humidity. This heavy increase in pollen concentration could very well cause problems for those who are allergic to airborne pollens.

The quantity of pollen grains in the air for Friday will be falling in the low range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to rising humidity, weakening winds and expected precipitation in the afternoon which tends to wash pollen out of the air.
