Pollen Index: 11.7 Pollen Level: high Predominant Pollen: Maple, Cedar/Juniper and Elm. Based on past pollen counts and expected weather conditions, pollen levels for Friday will be falling but will remain in the high range. This forecast of lower pollen concentration is based on rising humidity, weakening winds and expected precipitation in the afternoon and evening which tends to wash pollen out of the air. This reduction in pollen levels should be a relief to allergy sufferers.
