PHOENIX — Expect a hot and dry holiday weekend across the Valley and much of Arizona as high pressure strengthens overhead.

As high pressure rebuilds, a warming trend begins. Highs will climb back to near-normal by Saturday, with the lower deserts likely hitting 110° or more by Sunday.

This weather pattern is also leading to worsening air quality.
An Ozone High Pollution Advisory is in effect for the Valley on Monday. Light winds and sunshine are causing ozone levels to rise, especially in the afternoon.

Breathing in ozone pollution can cause chest pain, coughing, throat irritation, and difficulty breathing. Children, older adults, and people with asthma, COPD, or other respiratory issues are most at risk. Try to limit outdoor activity during peak afternoon hours.

To help reduce ozone pollution, carpool, take public transportation, avoid idling, and refuel after sunset.

Looking ahead, another round of extreme heat is likely next week, with the potential for near-record temperatures by midweek.

Afternoon highs could get up to 115 degrees by Wednesday. Heat risk will be Major to Extreme for parts of central and southwestern Arizona.

Remember to limit your outdoor activities between 10 a.m. to 6 p.m., drink plenty of water and electrolytes, bring pets inside, check on your friends and family to make sure they have adequate cooling and never leave kids of pets inside hot cars.
