MOST ACCURATE FORECAST: Scorching heat and air quality alerts in the Valley!

Posted at 6:46 AM, Jun 27, 2024

PHOENIX — It's a record-setting day in the Valley of the Sun!

Phoenix only dropped to 95 degrees this morning. That not only topped the previous record warm low for today of 93 degrees (set in 1990), but it also marked the warmest overnight low ever recorded in Phoenix during the month of June.

With more overnight lows in the 90s expected, more daily records could be set over the next week.

High pressure is bringing all this heat and sending daytime highs soaring above 110 degrees for the next several days in Phoenix, too.

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.

Sunny skies and lighter winds will also create an uptick in ozone pollution.

An Ozone High Pollution Advisory is in effect Friday and Ozone High Pollution Watches have been issued for Saturday, Sunday and Monday in Maricopa County.

People most vulnerable to the impacts of ozone pollution include children, older adults, adults exercising outdoors, people with heart or lung disease, and those suffering from asthma and bronchitis.

Exposure to ozone can increase the number and severity of asthma attacks, cause or aggravate bronchitis or other lung disease, and reduce the body's ability to fight infection.

Consider driving as little as possible, carpooling, and using public transportation. Also, re-fuel your vehicle in the evening and avoid idling in long drive-thru lines to help reduce pollution.

As high temperatures climb even further over the weekend, Phoenix will be back in record territory on Sunday. The current record high on Sunday is 115 degrees, set back in 2013.

The Valley will likely catch a break from monsoon storms over the next few days, but we could still see storms fire up in the heat of the day across the higher terrain.

The biggest hazards with any storms that develop across Arizona will be strong winds, dangerous lightning and small hail. We could also see some 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.

Storm chances will be back in the Valley on Sunday and likely stick around through the 4th of July holiday weekend. Stay tuned for updates as we get closer.
