Morning Weather Forecast - 3/25/26

Phoenix is expected to reach 101 degrees on Wednesday, which would break the previous record of 99°F.

Our heat wave continues, but we're finally approaching the end!

High pressure continues to focus on our region, keeping the warmth and dry conditions locked. The high pressure dome, however, is shifting eastward. It slowly glides east of Arizona over the next couple of days, and slips southeast of the state by Friday into the weekend. As a result, our temperatures will begin to trend downward as our moisture levels begin to increase this weekend.

This Week:

The forecast high reaches 101 degrees in Phoenix today. That high may jump to 102 by Thursday and Friday. The sky will remain sunny to mostly sunny for the next several days as well.

This Weekend:

The forecast high will slip to 99 on Saturday and 97 on Sunday. It will turn breezy in the Valley and a bit windy in the High Country over the weekend. Gusts around 20-25 mph are possible in Phoenix both days.

Big picture view:

As the ridge shifts to the southeast, it will help guide moisture from our south toward Arizona. This will bring a chance for scattered showers to the state, particularly eastern and northern Arizona, starting Sunday into Monday.

As a trough of more mild air begins to approach the West Coast, an additional chance for showers may pick up over Arizona around mid-next week. This pattern shift will also drop our forecast highs.

We're expected to top off in the mid-upper 90s this weekend and early next week. By mid-next week, the high temperature will drop to the low-mid 80s in Phoenix.
