Morning Weather Forecast - 3/27/26

Happy Friday! We're still in record-breaking territory, but changes are coming beginning this weekend.

The Brief

    • We're staying in triple digits on Friday in Phoenix, with a record-breaking high of 101 degrees expected.
    • Relief is finally in sight beginning this weekend, as a pattern change is projected to bring cooler temperatures and the first significant rain chances to the state in weeks.

PHOENIX - We've made it to the final day above 100 degrees in our 10-day forecast.

Today and the Weekend:

The ridge of high pressure impacting our state continues to shift eastward through the weekend. The shift brought us a high temperature of 99 degrees on Thursday, which fell below the 100 degree record for the date. This means our stretch of consecutive record-breaking days came to an end at 8 days straight.

However, we are still in record-breaking territory through Saturday. In fact, today is forecast to reach 101 degrees while the current record sits at 98.

As the high shifts over Texas, it will set up perfectly for moisture to wrap around the dome and guide up into Arizona. The moisture push will help bring a few spotty clouds to our state by Friday evening, with more widespread cloud coverage by this weekend.

This weekend the forecast high drops back to the upper 90s on Saturday and mid-upper 90s on Sunday. It will be breezy both days with gusts around 20-25 mph in Phoenix and 25-35 mph in Flagstaff. Eastern Arizona could see breezier conditions as early as today. The sky conditions shift from partly to mostly cloudy through the weekend, too.

By Sunday, there will be a low chance for a few passing showers or a thunderstorm over Southern and Eastern Arizona. The low chance for showers spreads into the higher elevations of northern Arizona overnight and into Monday. Even the Valley and surrounding lower deserts may see isolated showers or thunderstorms Sunday into early Monday. The chance sits at 10% in Phoenix and 20-30% around Flagstaff.

Looking Further Ahead:

Next week, a trough of more mild air will drop across the West Coast and move inland. Through next week, this will offer some moderation to our afternoon highs, with temperatures capping in the 80s beginning Wednesday and lasting into the following weekend. It may also bring additional chances of rain by mid-next week.
