MOST ACCURATE FORECAST: More triple digit heat and storm chances this week

Posted
and last updated

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

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

Storm chances are back this week, too.

Storms will be confined to northern and southern Arizona, but we could see a few storms back in the Valley on Wednesday or Thursday.

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

Although our Valley forecast will dry out, there will still be storm chances in the higher terrain and across northern Arizona through next week.

We could soon 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 hover in the upper 90s to low 100s through the weekend with cooler air toward the middle of next week.
