PHOENIX — Cooler air is on the way!
Back-to-back storm systems will move in this week dropping our temperatures and picking up our winds.
These storms will bring more clouds at times, but we won't see any rain in the Valley.
There's a slight chance of isolated thunderstorms in parts of the high country this week, but overall rain chances are very low across Arizona even as these storm systems move through.
Winds will pick up by midweek with Valley wind gusts around 25 to 30 mph on Wednesday and Thursday.
Up north, peak wind gusts could hit 40 mph, especially on Thursday.
Those winds will usher in some cooler air, dropping Valley highs from the low 100s Tuesday and Wednesday, to the upper 90s on Thursday. We'll cool off even more Friday with highs down into the mid 90s in Phoenix.
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.
September 10th this year also marked the latest day in any year with a low in the 90s. Previously the record was September 7, 2019.
