MOST ACCURATE FORECAST: Excessive Heat Warnings with a chance of storms

Posted
and last updated

PHOENIX — It's been another record-setting day in the Valley as the sizzling heat won't go away!

For the 24th consecutive day, Phoenix Sky Harbor reached 110 degrees, breaking the previous record of 18 straight days set back in June of 1974.

We have had 14 nights in a row with lows in the 90s! That breaks the previous record of 7 nights with lows in the 90s.

This unrelenting heat could break even more records in the days ahead with little 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.

Excessive Heat Warnings for the Phoenix metro area and lower elevations all across Arizona have now been extended through at least Wednesday now, while warnings in parts of the Grand Canyon below 4,000 feet are set to expire Monday night.

Monsoon moisture is slowly increasing as well, bringing storm chances back to much of the state.

The best chances for showers and thunderstorms in the Phoenix metro area will be on Sunday and Monday evening.

If we get rain, that could drop our temperatures through early next week. Otherwise, highs will stay near or above 115 degrees and lows will stay in the 90s.
