Forecast Discussion:

Ozone levels in the Tucson area were a little better than anticipated yesterday, ending up in the upper Good AQI range. As for PM10 and PM2.5, they continued to stay in the Good range as expected. Today, we expect fairly similar weather condition, but there is a trough approaching the region, which will begin to bring breezy afternoon winds. We will see off and on breezy winds throughout the forecast period as two trough will affect the area over the next several days. Additionally, we should see temperatures cool off a bit, dropping into the 80's by Thursday.

As for the air quality, the breezy afternoon winds each day, should help keep ozone levels relatively low. And as for particulates, we don't expect the winds to be strong enough to cause any significant dust issues. Therefore, we are forecasting all pollutants to stay in the Good AQI range through the forecast period.

Ozone and Your Health

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
