PHOENIX — After a few light showers and gusty winds last night, skies have cleared across most of the state today. Sunshine and dry conditions will help temperatures climb into the low 90s across the Valley.

With stagnant air and plenty of sun, however, pollution is building. An Ozone High Pollution Advisory is in effect today for the Phoenix metro area.

If you have asthma, COPD, or other respiratory conditions, try to limit your time outdoors during the afternoon when ozone levels peak. Exposure can trigger or worsen asthma and bronchitis, reduce lung function, and make it harder for your body to fight off infections.

Even healthy individuals, especially children, older adults, and anyone exercising outside, could experience symptoms like itchy eyes, coughing, wheezing, chest tightness, or shortness of breath.

To help reduce pollution levels, consider carpooling, using public transit, working from home, or waiting until after dark to refuel your vehicle.

Looking ahead, a weak system moves in Friday, bringing a slight chance of showers to the high country and northern Arizona.

A much stronger storm system follows this weekend. This one will bring gusty winds, rain and snow chances, and a significant drop in temperatures.

Winds could gust over 45 mph across higher elevations on Saturday and Sunday, increasing the risk for wildfires.

Colder air arrives Sunday, with temperatures dropping 10 to 20 degrees across the state.

Snow levels could fall to around 5,500 feet by Monday morning, with Flagstaff possibly picking up up to an inch of snow.

In the Valley, there’s a slight chance of isolated showers Sunday as highs fall into the upper 70s. We’ll continue to track changes and keep you updated.
