PHOENIX -- Thousands are flocking to the Valley of the Sun this weekend for NASCAR, the Cardinals game and the big ASU matchup, but the fanfare is being met with unseasonably hot weather.

A strong ridge of high pressure building in from the west is to blame for shooting temperatures more than 10 degrees above average for this time of the year.

Phoenix Sky Harbor reported a high of 90 degrees Saturday afternoon, just one degree shy of the daily high temperature of 91 set back in 2007. The normal high for this date is 79 degrees. Saturday’s morning low was 58.

A modest cooling trend is expected over the next seven days as high pressure slowly loses some strength. High temperatures are expected to remain in the mid and low 80s through most of next week. Overnight lows will be in the 50s.
