Evening Weather Forecast - 3/24/26

The Southwest is in for another big week of record warmth. FOX 10's Erica Horvatin has more of when we can expect some relief from the triple-digit temperatures later this week.

PHOENIX - Our hot streak continues this week.

Temperatures broke records across Arizona for the 8th consecutive day on Tuesday. There are an additional five days ahead where we'll likely break records. This will complete an 11-day stretch of consecutive records set.

This Week:

Even with a cooling trend the past few days, temperatures are still running 15 to 20 degrees warmer than normal. Our ridge of high pressure has begun to shift over the Southwest. As a result, the afternoon high temperature will remain in triple digit territory today and the rest of the week. However, the ridge is not as strong as last week, and will not reach up to 105 again.

The heatwave and record warmth will continue through Saturday, but a change-up is expected Sunday.

Tuesday night will be clear, with a low around 69 degrees in Phoenix.

Wednesday will be sunny with a high of 101 degrees. High temperatures will remain in the low 100s through Friday. Clouds will increase Friday, and the weekend is going to be cloudier across Arizona.

Starting This Weekend:

A slightly more mild push of air will approach from the West. At the same time, the ridge of high pressure will start to slip southeastward. As this happens, the clockwise winds around the dome will guide moisture from the south of Arizona up and into our state. This will help bring down our temperatures, gradually.

Highs slip back into the 90s over the weekend and 80s are possible by next week. In addition, some moisture will finally reach into the state. At least a few scattered showers are possible starting Sunday and lasting into Monday. It will turn partly to mostly cloudy as well, and those more pleasant sky conditions will continue through next week.
