PHOENIX — After a beautiful fall weekend, get ready for a warm-up this week!

The storm system that helped keep us cool is moving away, meaning our temperatures will start climbing over the next few days.

By the middle of the week, we’ll briefly be back in the triple digits.

Then, things get a little more interesting toward the weekend.

Moisture from what’s left of Hurricane Priscilla could move into the Desert Southwest, boosting rain chances for Arizona starting Thursday.

It’s still too early to know exactly where and how much rain we’ll get, but chances are growing for some showers in Arizona late this week and into the weekend along with cooler temperatures.

Stay with ABC15 for updates as we get closer.
