Arizona weather forecast: Another day of record-breaking heat expected

Evening Weather Forecast - 3/22/26

Sunday reached triple digits in the Valley, with another record potential expected for Monday. FOX 10's Erica Horvatin has more on the record warmth as we approach another hot week.

PHOENIX - Happy Spring! The weekend was off to a hot start with another record-breaking day.

Sunday:

Temperatures fell a few degrees across Arizona on Sunday. However, record warm temperatures were still reached for most of the state.

Clouds rolled in overhead, thanks to weakening high pressure, and a nearby disturbance, which drew upper level moisture through Arizona. Skies will stay mostly to partly sunny across Arizona tonight and Monday. It will cool to around 68 degrees tonight in Phoenix.

Monday:

Temperatures will cool a few more degrees on Monday.

It will warm to around 98 degrees, which is cooler, but still record warm. In fact, temperatures will still be record warm in the Valley everyday through this Friday. Highs will hover around 100 degrees each day. The high country will see more record warm temperatures on Monday as well.

Looking Ahead:

Another ridge of high pressure will form early next week, continuing our stretch of triple digit temperatures. Record-breaking temperatures will continue through early next week with dry and hot conditions expected.

A change in the weather pattern is likely next weekend, and temperatures will finally fall into the low 90s and upper 80s. On top of that, rain chances return to Arizona next Sunday, through early the following week.

Weekend Recap:

Phoenix hit a high of 105° on Saturday, breaking our 2004 record of 97° and a record that was set back in 1990 of 94°, with the normal average sitting at around 80°.

The ridge of high pressure responsible for bringing in the historic heat wave will begin to break down. Winds will be breezy, especially for the high country coming in from the southwest.

Our extreme heat warnings will officially expire on Sunday at 8 p.m. with temperatures expected to drop by next weekend. Those who are sensitive to the heat should limit time outdoors, and use caution in the heat.

Our Friday forecast felt like summer with another record-breaking day as Phoenix hit a high of 105° with the average sitting at 79. This breaks our 2017 record of 96°.
