Atmospheric scientists from the Colorado Climate Center pulled together the number of days reaching 90 degrees or above this year for several climate stations across the state and compared it with the 1991-2010 average number of 90 degree days. All but two stations had more 90 degree days than average this year, Akron and Dillon (Dillon had done). On the flip side, Alamosa had over double the average number of 90 degree days so far, and Steamboat Springs has seen over triple!
