 Arizona News Radio. Phoenix set a record high temperature for the date on Friday. National Weather Service meteorologist Austin Jamison says it was a real scorcher. It sure is. In fact, we set a record at Sky Harbor. It's 118, and the previous record was 116 degrees last night in 1983. It was also the hottest day of the year so far in Tucson with a high of 111, and our heat was nothing compared to Palm Springs, California.
