PHOENIX — Our first big heat wave of the year is now underway!

Phoenix hit 110 degrees for the first time this year Wednesday afternoon. (On average, we tend to see our first day at 110 degrees or higher on June 11th.)

Now, we're headed into record territory in the days ahead.

The forecast calls for highs in Phoenix at 113 degrees on Friday, 114 degrees on Saturday and 113 degrees on Sunday, which could all set new heat records in Phoenix.

Here's where the records stand currently:
Friday: 111 (set in 1978)
Saturday: 114 (set in 1918)
Sunday: 112 (set in 2019)

We could also set new records for overnight warmth as lows only drop into the mid to upper 80s in Phoenix over the next few days.

With heat this intense, Excessive Heat Warnings are in effect for the Phoenix metro area through Sunday.

These heat alerts also extend across southern and western Arizona, and across the lower elevations of Yavapai and Gila counties.

With these warnings in effect, ABC15 Weather Action Days are in place through Sunday. Take action to stay safe in this dangerous heat.

Remember that heat is the number one weather related killer, so stay hydrated and limit your time outside when temperatures get this hot. Make sure to keep your pets inside, too.

While our Valley forecast will stay dry, we'll see a few thunderstorms in southeastern Arizona, along the Mogollon Rim or in the White Mountains over the next few days.

Lightning from these storms may spark new wildfires across our state.

By Sunday, moisture will clear out and winds will pick up. That will help drop temperatures, but fire danger will increase even more.

Fire Weather Watches are now in effect for much of northern Arizona on Sunday.
