Forecast Discussion:

An Ozone High Pollution Advisory is in effect for Maricopa County today and tomorrow, with a High Pollution Watch for Wednesday.

Two low pressure systems are making their way across the central United States, with Hurricane Beryl among them making landfall in southeastern Texas. High pressure is making its way behind the areas of low pressure, moving in from the Pacific Coast. Arizona will see breezes of 5-15 mph in the afternoon today before weakening slightly tomorrow and Wednesday.

Unfortunately, dry weather will continue through most of the week, with tropical moisture to the southeast being blocked by the current upper air pattern of high pressure. Temperatures in the Phoenix metro area will reach 113-116°F in the afternoons, resulting in an Excessive Heat Warning issued by the National Weather Service lasting from today through Thursday. Chances for rain will increase towards the end of the week as moisture seeps into the state from the southeast.

As for air quality, ozone will be the main area of concern going forward. Ample sunlight and relatively light breezes in the late morning will allow ozone concentrations to increase within the Phoenix metro area. We are currently watching wildfire smoke track to the south-southeast out of southern Utah. We are not expecting too much of an effect on smoke concentrations in the valley, but wildfire smoke can cause ozone levels to increase as it carries ozone-forming compounds. We are forecasting an area of high pressure to remain overtop the Four Corners region throughout the entire week, which may result in this smoke modified air mass remaining over the state.

Stay up to date on the latest high temperature concerns with your weather authority, and check in with us tomorrow for the latest on air quality.

Have a great start to your week!

People most vulnerable to the impacts of air 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. Symptoms may include itchy eyes, nose and throat, wheezing, coughing, shortness of breath, chest pain, and upper respiratory issues | View Ozone Fact Sheet >

Please help reduce ozone by doing one or more of the following:

  • Drive as little as possible, carpool, use public transit or telecommute
  • Re-fuel your vehicle in the evening
  • Avoid waiting in long drive-thru lines, if possible
  • Use low-VOC (Volatile Organic Compounds) or water-based paints, stains, finishes and paint strippers - delay big painting projects
  • Make sure containers of household cleaners, garage and yard chemicals, and other solvents are sealed properly to prevent vapors from evaporating into the air
