Pollen Index: 8.2 Pollen Level: medium-high Predominant Pollen: Ragweed, Sagebrush/Sage and Chenopods. Concentration of pollen grains in the air for Monday will be falling in the moderate range. This relief in pollen levels is caused in part by falling temperatures, rising humidity, and heavy rains in the evening which tend to wash pollen out of the air. That's good news for allergy sufferers.
