PHOENIX — Monsoon moisture is clearing out, taking storm chances with it.

There's a chance for thunderstorms in eastern Arizona the next couple of days, otherwise there rest of Arizona looks storm-free through the end of the week.

As drier air moves in and storms clear out it's getting hotter!

High temperatures will creep up to above average Thursday, then we'll see a big warm-up by the weekend.

Valley highs will soar to between 110 and 113 Friday through the weekend as high pressure moves in. This would be the first time Phoenix reaches 110 degrees or higher in nearly three weeks thanks to the active monsoon season we've had so far.

It'll also be dangerously hot along the Grand Canyon where an Excessive Heat Watch has been issued from Friday afternoon through Sunday evening. With temperatures expected to reach 110 degrees at the base of the canyon, be sure to have adequate gear, food and water if you plan on hiking in the area this weekend.

Morning lows will get warmer too, only cooling into the mid to upper 80s to near 90 degrees through the weekend. So we won't get much relief from the heat overnight.

We're also keeping a close eye on our air quality.

Ozone levels will climb again and an Ozone High Pollution Advisory has been issued for Thursday and an Ozone High Pollution Watch has been issued for Friday.
