Pollen Forecast for Philadelphia/Northeast Philadelphia Arpt, Pennsylvania

The pollen levels for Friday will be increasing over today's levels in the moderate range. This increase is due to strong winds and decreasing humidity.

Concentration of pollen grains in the air for Saturday 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. That's good news for allergy sufferers.
