MOST ACCURATE FORECAST: Unrelenting heat wave continues to break records

Posted
and last updated

PHOENIX — This unrelenting heat will shatter even more records this week, with no relief in sight.

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.

A combination of sizzling hot daytime highs (well 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.

Phoenix has hit 110 degrees or more for the past 18 days in a row, tying the all-time record set in June of 1974, and we have a least another week of these incredibly hot temperatures to get through.

We have also now broken the record of 8 consecutive mornings with low temperatures in the 90s and we will add to that record in the days ahead, too.

Excessive Heat Warnings for the Phoenix metro area and lower elevations all across Arizona have now been extended through the end of the week.

Heat Advisories are also in effect for the high country and much of northern Arizona through today.

Monsoon moisture will combine with our intense heat to trigger storms around our state over the next few days. The best storm chances are for areas along the Mogollon Rim and across southeast and south-central Arizona.

Although it was an eventful Monday with high winds and blowing dust, the Valley looks to stay mostly dry this week.

More monsoon moisture is set to move in by the weekend. Stay tuned as we get closer.
