Below are the relative humidity values from yesterday at 4PM. Most regions are in the 20-30% range with stations over western Colorado in the single digits. Thankfully winds were weak, so there were lesser fire concerns. Some moisture was able to hang on over the far southern border, so there were a few showers and thunderstorms over the San Juan and southern tip of the Southeast Mountains during the afternoon. The Cumbres Trestle SNOTEL site in the area recorded 0.4 inches. As we start August, the drought continues to worsen over the Southeast Plains\/Mountains and northwest corner of the state with only limited improvements over the Northern Mountains and Front Range.

Also shown optionally are fire burn areas (post 2012), which are updated throughout the season to include new burn areas.
