MOST ACCURATE FORECAST: More chances for monsoon storms overnight!

and last updated

PHOENIX — More monsoon storms are possible in the Valley overnight!

So, we remain in ABC15 Weather Action mode as the risk for thunderstorms and flooding continues.

Stay weather-aware and be prepared to seek shelter immediately if storms strike. Also avoid driving through flooded roadways or washes. It could be dangerous, or even deadly.

Flood Watches are now in effect across parts of western and northern Arizona. These areas, along with much of the high country, will see storm chances continuing into Saturday evening.

Then, we'll dry out for the rest of Labor Day weekend across most of the state.

Temperatures will stay below normal with highs in the upper 90s to low 100s and early morning lows in the upper 70s to low 80s.

As high pressure returns toward the end of next week, the heat will crank up again.

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.

We're also now up to 34 days with lows in the 90s. The old record was 28 days set in 2020.
