PHOENIX — Cooler air is on the way!
We're tracking a storm system passing to our north that will pick up our winds and bring in a nice dose of cooler air to Arizona by the end of the week.
Valley highs will fall into the mid 90s on Wednesday and low 90s Thursday and Friday.
Overnight lows will cool back into the 60s by the end of the week, too.
Watch out for gusty winds across Arizona on Wednesday, though.
Peak gusts could hit 30 mph in the Valley and 50 mph across northern Arizona!
Areas all along the Mogollon Rim and across northeastern Arizona will be under Wind Advisories from 10 a.m. to 6 p.m.
High pressure will return over the weekend sending Valley highs back into the upper 90s by Sunday and we'll be flirting with the triple digits again early next week.
Phoenix has now had 126 days this year at 100 degrees or more. This is the sixth most on record. The average number is 111 days and the all-time record is 145 days, set back in 2020.
