Today
The quantity of pollen grains in the air for Monday will be falling but will remain in the high range. This lowering of pollen concentrations is a result of rising humidity, weak winds and expected precipitation in the afternoon which tends to wash pollen out of the air.
Outlook
Concentration of pollen grains in the air for Tuesday will be increasing and extend further into the very high range. This higher level is caused in part by higher temperatures and the lower dewpoint.
