MOST ACCURATE FORECAST: Another temperature drop coming to Arizona!

Posted at 7:01 AM, May 22, 2024

PHOENIX — It's heating up in the Valley, but we do have another temperature drop on the way!

Afternoon temperatures will top out in the mid to upper 90s for the rest of the week, putting within a few degrees of the average for this time of year.

Breezes will pick up slightly on Thursday afternoon, and even more on Friday and Saturday, helping to mix our air and not allow pollution to build up as much.

Those winds will come as another storm system approaches. Right now, it looks like the rain will stay too far north to impact Arizona, but it will bring in some cooler air heading into Memorial Day weekend.

In Phoenix, we'll drop from 99 degrees on Friday to 91 on Saturday as we start the holiday weekend.

Then, high pressure returns sending Valley temperatures back into the low 100s by Memorial Day and it's looking even hotter for the middle of next week.
