MOST ACCURATE FORECAST: Storm chances return for this last week of the monsoon season

Posted
and last updated

PHOENIX — It's a hot start to the week as high pressure sits overhead.

Phoenix hit 105 degrees on Monday, putting us just three degrees shy of today's record set in 1989.

We'll gradually drop a few degrees throughout the week, but we are expecting triple digit heat through at least Thursday.

Storm chances are back, too.

The best chances for showers and thunderstorms are across the higher terrain, but there's a slight chance we could see some isolated storms in or around the Valley over the next few days.

The monsoon season officially ends this Friday, September 30th.

We could be nearing the end of our 100-degree temperatures for 2022, as well. Phoenix's average last 100 degree day is October 5th.

Right now, it looks like highs will drop into the upper 90s by Friday and stay there through the weekend and into next week.
