MOST ACCURATE FORECAST: Dangerous heat continues this week

Posted
and last updated

PHOENIX — We are dealing with a long and dangerous stretch of extreme heat as we begin a new week.

An Excessive Heat Warning has now been extended for the Phoenix metro area and most of western and southwestern Arizona through at least Thursday.
For northern and southern Arizona the warnings go through at least Tuesday.

Now through Thursday are ABC15 Weather Action Days as a reminder to take action to keep you and your family safe during this dangerous heat wave.

Limit your time outside during the afternoon, stay hydrated with water and electrolyte drinks and never leave kids or pets alone in your vehicle.

Valley highs will continue to stay between 112-117 degrees through the next week.

Phoenix highs will also continue flirting with records on Monday and Tuesday. The current record high for Monday's record high is 115 degrees and Tuesday's is 116 degrees.

Overnight lows will stay very warm too, only cooling into the upper 80s to low 90s across the Valley.

The warm mornings combined with the sizzling hot afternoons will increase the risk for heat illnesses, so make sure that you're staying hydrated and limiting your time outdoors during the hottest hours of the day. Keep an eye on kids and the elderly as they are more susceptible to heat-related impacts.

We'll see the return of monsoon moisture chances to the high country by early next week, with chances increasing as the week goes on.

The Valley is expected to stay dry, with a slight chance for showers and storms back in the mix by the end of next week.

The biggest hazards with any storms that develop across Arizona will be strong winds, dangerous lightning and small hail. We could also see downpours and areas of flooding, especially along burn scars, so stay weather-aware and remember to never attempt to drive through flooded washes or roadways.

Air quality will be an issue again in the Valley next week.

An Ozone High Pollution Watch has been issued for Tuesday. These alerts could be upgraded to advisories as we get closer.

If you have a respiratory condition, like asthma, bronchitis or COPD, you may want to limit your time outside or you may have difficulty experience chest pain, coughing, throat irritation, congestion or difficulty breathing.

Everyone should try to carpool, take public transportation or work from home whenever air quality alerts are issued.
