PHOENIX — The ridge of high pressure that brought hot temperatures to the Valley this weekend will begin to break down as we head into the start of the week. Bringing some much-needed COOL relief our way.
Expect clear skies, light winds and moderate air quality this week.
We'll be tracking a storm system moving in. There won't be a lot of moisture with it, right now light scattered showers across northern and eastern Arizona are only at 10 percent Wednesday through Friday.
Winds will pick up midweek with gusts in the Valley around 25 mph and in the high country around 40 mph.
The good news is we will get some cooler air, Valley highs will fall into the upper 90s by Thursday and mid 90s on Friday and into next weekend.
This cool-down will mark the beginning of the end of our record-setting heat season.
Phoenix reached temperatures of 110 degrees or hotter 55 days this year, breaking the old record of 53 days set in 2020.
Phoenix has also reached a high of 115 degrees or hotter 22 days this year. That too is a new all-time record, topping the previous one of 14 days set in 2020.
When it comes to overnight temperatures, Phoenix had 35 days this year with lows in the 90s. The previous record was 28 days set in 2020.
