MOST ACCURATE FORECAST: Triple digits stay with us for the first weekend of fall

and last updated 2020-09-25 19:55:44-04

Fall is here, but a real fall cool-down is nowhere in sight.

Instead, high pressure is keeping the triple digits in play.

Valley will top out near 105 Monday, putting us nearly 10 degrees above the average high for this time of year which is 97.

While the 100s are going to stick around through the weekend and into next week, it's no longer looking like we'll see record heat. As a disturbance passes by to our east, our Valley highs now look to reach the low 100s for most of next week.

Expect a high between 103 Saturday and 102 on Sunday.

Overnight lows will still be nice as we cool into the mid 70s each morning.

We'll be sunny and dry statewide through the weekend and early next week for the final days of the monsoon season.

This will go down as the driest monsoon on record for many Arizona cities, including Yuma, Casa Grande, Kingman, Flagstaff, Show Low, Prescott and Lake Havasu City.

Here in Phoenix, we picked up 1 inch of rain, but 0.90 inches of that was in just one night!

With only two days of measurable rain in Phoenix, this has been the least active monsoon on record. In terms of total rainfall, it has been the 13th driest on record.
