Summer starts with a sizzle! Temperatures are back on the rise and we could soar above 110 degrees for the first time this year.  

Excessive Heat Warnings go into effect for many desert locations today, including the Valley, from 10 am Thursday until 9 pm Friday. These days will be ABC15 Weather Action Days as temperatures approach dangerous levels. 

We're expecting to hit 110 for a high on Thursday, just the second time this year Phoenix will have hit that mark. Temperatures will be even hotter yet on Friday with a forecast high 111 and early morning lows only in the 80s.

Take action to protect yourself from this heat! Stay indoors as much as possible and make sure to drink plenty of water.  


Air quality remain will remain an issue as well. The Valley will be under another High Pollution Advisory for ozone on Thursday, so limit your time outside if you have any respiratory issues. This may be extended to Friday as the intense heat sticks around.

A disturbance will track north of our state this weekend, bringing more breezes and a decent drop in temperatures.

The Valley will fall back down into the low 100s by Sunday.
