MOST ACCURATE FORECAST: Monsoon storm chances back in the Valley this weekend

Posted
and last updated

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

As of Friday, 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.

As monsoon moisture increases this weekend, storm chances will ramp across our state and we'll even see a slight chance of storms in the Valley.

Scattered storms will impact northern, eastern and southeastern Arizona and some of those storms may be severe with hail, high winds and flooding.

A Flood Watch is in effect on Saturday for parts of Coconino and Mohave counties. Flash flooding will be possible along the Grand Canyon and near Havasupai Falls.

Consider changing your plans if they involve hiking, boating or paddle-boarding in/near a slot canyon or normally dry wash near the Grand Canyon this weekend. If you still decide to go, check in at a nearby visitor center or ranger station before heading out.
