Colorado Air Quality Advisory - This Widget puts a small image on your desktop to show if the air quality is Red, Blue, Split or Inactive (black). If you are like me and like to have a fire this is a quick why to find out if you can burn. The Widget updates every two hours. The winter air quality advisories are issued daily from Oct. 31 through March 31 at 4 p.m. You can find more information on the advisories at http://apcd.state.co.us. Thanks and enjoy.
