# HEADLINE -------------------- OZONE HIGH POLLUTION ADVISORY FOR MARICOPA COUNTY INCLUDING THE PHOENIX METRO AREA THROUGH MONDAY # SUMMARY -------------------- The Arizona Department of Environmental Quality (ADEQ) has issued an Ozone High Pollution Advisory for the Phoenix Metro Area through Monday. This means that forecast weather conditions combined with existing ozone levels are expected to result in local maximum 8-hour ozone concentrations that pose a health risk. Adverse health effects increase as air quality deteriorates. Ozone is an air contaminant which can cause breathing difficulties for children, older adults, as well as persons with respiratory problems. A decrease in physical activity is recommended. You are urged to car pool, telecommute or use mass transit. The use of gasoline-powered equipment should be reduced or done late in the day. For details on this High Pollution Advisory, visit the ADEQ internet site at www.azdeq.gov/forecast/phoenix or call 602-771-2300. # DETAILS -------------------- ISSUED AT Sunday, August 23, 2026 at 7:45 AM MST ISSUED BY Relayed by National Weather Service Phoenix AZ HEADER Air Quality Alert

Closest strike: 12.45 miles Storms Approaching Stay alert and frequently check WeatherBug to see if storms are moving toward you. Be mindful that new storms can also form with little notice.

There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE NORTHERN HIGH PLAINS AND GREAT BASIN SUMMARY Thunderstorms capable of large hail and severe-caliber wind gusts will continue this evening across eastern Montana and the western Dakotas, with other severe storms capable of wind gusts across the Great Basin. 01z Update Primary severe-weather corridor this evening will persist across east/northeast Montana to portions of the western Dakotas, but likely on a more marginal/isolated basis by the overnight. Other wind-producing storms will remain a possibility over the next couple of hours in areas such as northern Utah/far southeast Idaho, as well as southern Arizona. A couple of severe storms will remain a possibility this evening across northeast Ohio into northwest Pennsylvania. See Mesoscale Discussion 2108 for additional details. Later tonight, a modest increase in isentropic ascent associated with a south-southwesterly low-level jet may aid thunderstorm development late tonight and early Monday morning across parts of northeast Oklahoma and southeast Kansas to the Ozarks. Overall instability is expected to remain fairly weak (MUCAPE generally less than 1000 J/kg), but some clustering may occur with a low chance for localized severe wind gusts.
