Pollen Index: 10.5 Pollen Level: high Predominant Pollen: Cedar/Juniper The quantity of pollen grains in the air for Sunday will remain relatively stable in the very high range. This is a result of stable humidity. No change doesn't mean no pollen, it just means that pollen producing plants are delivering pollen at a steady pace.
