August has been one for the record books when it comes to high temperatures in Northern Arizona. An all-time record was set in Flagstaff Monday. With a high of 91 degrees, not only did the city set a new record high temperature, besting 88 degrees set in 2002, but it marked five days with highs of 90 or greater in the month of August. The National Weather Service says that has never happened since records began being kept in 1899. The last time Flagstaff had one day of 90 degrees or higher in August was 2009. Other cities that set new records Monday include the Prescott Airport, which set a new record of 99 degrees, surpassing the old record high of 97 last set in 2011. Winslow’s high was 103 degrees, which broke the record of 99 degrees set in 2002. It was 114 at Phantom Ranch, which broke the record of 113 last set in 1986. Seligman’s high was 104, which broke the record high of 100 degrees that last set in 1939. Look for more records to fall across Northern Arizona on Tuesday.
