Concentration of pollen grains in the air for Saturday will be unchanged in the extremely low range. Published Multidata research shows the possibility of trace or low levels of pollen being carried from distant regions even during this period of a lack of local pollen production.

Today

The pollen levels for Friday will remain relatively stable in the extremely low range. Although pollen is almost non-existent at this time, the budding trees are not far off. By the time the tree buds are noticeable, the new pollen is already in 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.
