This forecast will be updated on Friday, September 20 or sooner if necessary.

In October of 2015 the EPA modified the National Ambient Air Quality Standard (NAAQS) for ozone. The old standard was 75 ppb (8 hour average). The new standard is now 70 ppb (8 hour average).

You may or may not have noticed, but one of the things that is unique and special about my ozone AQI forecast is that unlike almost everybody else, I let you see what the forecast was. That allows the user an opportunity to see how accurate my forecast is (or is not). That is a feature I wish the weather web sites and other AQI forecasters would add to their web pages.For Western Nevada County only, check out Ozone Maps at http://www.sparetheair.com/
