Based on past pollen counts and expected weather conditions, pollen levels for Monday will be falling into the extremely low range. The cause for the falling pollen levels is rising humidity and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air.

Allergy Facts

Most pollen grains are 20 to 40 micrometers in size, however, there are many that are far from the norm. Pumpkin pollen grains, for example, can reach 250 micrometers in diameter--almost large enough to see with the naked eye.
