Pollen Index: 9.2 Pollen Level: medium-high Predominant Pollen: Ragweed, Chenopods and Grass. The quantity of pollen grains in the air for Thursday will be falling in the moderate range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to rising humidity and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air. Relief is in sight.
