MOST ACCURATE FORECAST: Flash Flood Watches in effect across much of Arizona

Posted
and last updated

PHOENIX — Destructive monsoon storms rolled through the Valley Thursday night!

Many of these storms have been severe and bringing damaging winds, hail and dangerous lightning.

Storms will continue to move through in the overnight hours, so stay safe and stay inside.

A High Pollution Advisory is in effect for the Valley too due to all the dust that has moved in.

Flood Watches are also now in effect across much of the state through Saturday, including here in the Phoenix metro area.

Storm chances will stick around through Saturday, then we'll dry out in the Valley for the rest of Labor Day weekend.

As storm chances ramp up, temperatures are dropping too. Valley highs will fall into the upper 90s to low 100s starting Friday and stay there through Labor Day weekend.

Then, as high pressure returns, the heat will crank up toward the end of next week.

There's still a chance of adding more 110-degree days to our tally which is already at 52 for the year. That's the second most ever recorded. The record is 53 days set in 2020.

Phoenix has also had 22 days so far at 115 degrees or hotter, the most ever recorded in a single year. Previously, the record was 14 days set in 2020.

Today's early morning low temperature could set a record, too. Phoenix only dropped to 92 degrees, and if we don't drop below that before midnight we will set a new record warm low today. The current record is 91 degrees set in 2011.

We're also now up to 34 days with lows in the 90s. If this morning's low holds, today will be day 35. The old record was 28 days set in 2020.
