Monsoon storms could return this weekend

PHOENIX — Phoenix is in the middle of the longest stretch of triple-digit days ever recorded!

As of today, we’ve had 82 days in a row at 100 degrees or hotter. The previous record was 76 consecutive triple-digit days set in August of 1993.

And there is no relief in sight!

Valley highs will top out around 110 degrees over the next several days with overnight lows in the upper 80s to low 90s.

As temperatures heat up, we’re also getting close to the record number of days with lows in the 90s.

So far this year, we’ve had 34 days with overnight lows in the 90s. The record is 35 days, set just last year. We could tie and potentially break that record over the weekend.

The Valley will stay dry, but as monsoon moisture returns we could see a few showers and thunderstorms develop across southeastern Arizona today.

As monsoon moisture increases this weekend, storm chances ramp up across Arizona.

We’ll see scattered storms across the high country in northern, eastern and southeastern Arizona through the weekend.

Some storms in the high country may become severe, producing hail, high winds, and flooding.

A Flood Watch takes effect Saturday for parts of Coconino and Mohave counties, meaning flash flooding will be possible along the Grand Canyon and Havasupai Falls.

Have a way to receive warnings and be prepared to take action should warnings be issued. Consider changing your plans if you’re going to hike, boat, or paddle-board to a slot canyon or normally dry wash. If you do still decide to recreate, check in at a nearby visitor center or ranger station.

Here in the Valley, there’s a slight chance for spotty storms Saturday and Sunday, with chances continuing next week.
