Predominant Pollen: Cedar/Juniper, Birch and Hazelnut.

Outlook

Pollen concentrations for Saturday will be greater than today's levels in the moderate range. Since the weather has a major influence on pollen dispersal, this increase is due in part to drier air. If you have these allergies, tomorrow will likely be more difficult outdoors.

Today

The quantity of pollen grains in the air for Friday will be falling into the very low range. The cause for the falling pollen levels is rising humidity, weak winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air.

Allergy Fact

Although plants with showy flowers tend to be less allergenic, some still cause allergy if their pollen becomes airborne. An example is the tree called catalpa, which has large, distinct, and numeous white flowers, and is a source of allergy for some people.
