PHOENIX — Monsoon moisture will continue to keep storm chances in the forecast throughout the week across Arizona.
The highest storm chances will be across the higher terrain in northern, eastern and in southeastern Arizona, but we may see a few isolated storms make it down into the Valley too.
Any storms that develop could produce gusty winds, blowing dust, dangerous lightning, small hail, downpours and flooding, especially along our burn scars. So, stay weather-aware and remember to never attempt to drive through flooded washes or roadways.
Temperatures will stay very hot with Valley highs above 110 degrees and overnight lows in the upper 80s to low 90s for at least the next several days.
The hottest days will be Friday and Saturday as Phoenix approaches 115 degrees. With temperatures that hot, the risk for heat-related illnesses like heat exhaustion and heat stroke will be going up.
So, limit your time outside in the late morning and afternoon, stay hydrated with water and electrolyte drinks, and never leave kids or pets alone in your vehicle.
Air quality will be getting worse throughout the week too as ozone pollution builds in.
The Arizona Department of Environmental Quality has issued Ozone High Pollution Watches for Thursday and Friday this week. Those will likely be upgraded to Advisories as we get closer.
Breathing in ozone pollution can lead to health impacts like chest pain, coughing, throat irritation, congestion and difficulty breathing. Kids, older adults and anyone with any kind of respiratory condition like asthma, bronchitis or COPD can be especially susceptible to the impacts of ozone pollution. So, limit your time outside in the afternoon when ozone pollution is peaking.
Everyone can help prevent our pollution problems from getting worse by carpooling, taking public transportation or working from home. Also, wait until after dark to fill up your gas-powered vehicles and avoid idling in long drive-thru lines.
