A few isolated showers and rumbles of thunder are around the Valley on this Thursday morning as a weak disturbance moves through the area. These showers will end and move off toward the northeast later this morning.

This morning, high pressure is sitting just southwest of the Four Corners as it continues to move westward. By this afternoon, the high will be directly over Arizona, and tomorrow, it will be over the northwest corner of the state before finally centering itself over Nevada Saturday through the first part of next week.

When it comes to storm activity as, the high slowly moves westward, expecting storm chances to increase across the region, with the flow becoming more favorable for bringing storms off the higher terrain and into the Valley. The best chances will be this weekend into the first part of next week. That said, we certainly can't rule out some isolated thunderstorms again this afternoon and tomorrow afternoon. The main threats will be strong gusty winds, brief heavy rain, and lightning. Afternoon high temperatures will also be well above average during this period, with highs in the 110-115 degree range today through Sunday.

Regarding air quality, with calmer winds, only slight storm chances in the afternoon today and tomorrow, and the possible influence of wildfire smoke over the region from fires across the Western United States, we are forecasting higher ozone levels, so an Ozone High Pollution Advisory is in effect for today and tomorrow. With increased storm chances and breezes starting this weekend, values are expected to lower below the health standard. PM-10 (dust) is forecast to be in the upper Good to low Moderate AQI category due to morning stagnation and the chance of some outflows moving through the region.

Make it a great Thursday!

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
