Pollen Forecast for Mainland, Pennsylvania

Pollen concentrations for Tuesday will be falling in the moderate range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to rising humidity, relatively calmer 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 Wednesday will be increasing over today's levels in the moderate range. This results in part from windy conditions. These overall conditions could make it a bit more difficult for those who are allergic to airborne pollens.
