Pollen Index: 9.8 Pollen Level: high Predominant Pollen: Ragweed, Nettle and Chenopods. The quantity of pollen grains in the air for Thursday will be falling but will remain in the high range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to lack of winds and expected precipitation in the morning and evening which tends to wash pollen out of the air.
