Flagstaff set a new record for Aug. 17 at 2 p.m. Monday at Flagstaff Pulliam Airport as it reached 90 degrees, two degrees above the previous record set in 2002. The largest gap between the new and old record occurred on Sunday when Flagstaff reached 93 degrees, 4 degrees above the previous record that was set 81 years ago.
Although the city has continued to set new heat records in recent years, it still hasn’t hit the triple-digit mark — the all-time high is 97 degrees, set July 5, 1973.
Many other locations around northern Arizona surpassed 100 degrees at least once during the weekend, including Page, Phantom Ranch, Seligman and Winslow.
Between June 15 and Sunday, Flagstaff has received 1.47 inches of rain, which is significantly less than the norm of 4.51 inches.
During the historically dry year in 2019, Flagstaff received 1.06 inches between mid-June and mid-August. The second driest season on record was in 1996 when 1.10 inches fell during the same two-month span.
But Flagstaff’s dry spell is being felt across the Southwest, causing varying drought severity.
“Specifically, concerning this week, the anomalously strong area of high pressure currently located over the Southwest is limiting atmospheric moisture and helping to produce these very hot temperatures,” Lynum said.
