Allergies & Pollen Count for Henryton, Maryland
Today's Condition

Concentration of pollen grains in the air for Friday will be falling but will remain in the high range. This relief in pollen levels is caused in part by falling temperatures, lack of strong winds and expected precipitation in the morning and evening which tends to wash pollen out of the air.
