MOST ACCURATE FORECAST: Historic heat wave continues! More 110s coming to Phoenix

Posted
and last updated

PHOENIX — We're in the midst of a historic heat wave and it's about to get even hotter.

Phoenix has hit 110 degrees or more for the past 12 days in a row and we have a least another week of these incredibly hot temperatures to get through.

The record for the most days in a row with highs at 110 degrees or more is 18 set in June of 1974. But, it is looking likely that we could tie or break this record this year.

We remain in ABC15 Weather Action Mode as a reminder to take action to keep yourself and your family safe in this extreme heat.

Heat is the number one weather-related killer. So, limit your time outside during the hottest part of the day and stay hydrated. Keep an eye on kids and the elderly as they can be the most affected by this heat. Bring your pets indoors, too.

Excessive Heat Warnings for the Phoenix metro area and all of western Arizona are now in effect through next Tuesday night. These heat alerts are also in effect for the lower elevations of the Grand Canyon through this weekend and the lower elevations of Yavapai County starting Friday.

A combination of sizzling hot daytime highs (above 110 degrees across the Valley) and warmer-than-normal overnight lows (in the upper 80s to low 90s) will increase the risk for heat illness.

Record highs are in jeopardy on Thursday, Friday and Saturday here in Phoenix as temperatures hit 115 degrees or more.

Nearly a month into the monsoon, we are finally starting to see moisture increase and storm chances across parts of the high country and southeastern Arizona.

These storms won't be big rainmakers, but they could produce strong winds and dry lightning that could spark new wildfires.

There's a slight chance a few weakening storms could approach the Valley overnight or early in the morning. While the threat of rain is low, we could get gusty winds and areas of blowing dust, so stay weather-aware.
