Pollen Index: 11.2 Pollen Level: high Predominant Pollen: Maple, Cedar/Juniper and Poplar/Aspen/Cottonwood. The pollen levels for Tuesday will be falling but will remain in the high range. This lower level is caused by lack of winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air. This will improve your outlook if you have allergies and enjoy the out of doors.
