Forecast Discussion:

It will be more of the same this week in the Phoenix area as far as the weather is concerned. We continue to see a blocking pattern where we have a low-pressure system sitting off the coast of the California Baja, and a high-pressure system over the southwest region. These opposing systems will keep temperatures near 80 degrees this week (still above average for this time of year) and calm winds throughout the days. No hope for rain this week, but hopefully we'll see a decent system come through soon!

Over the weekend, both PM10 and PM2.5 remained in the Moderate AQI category. Localized activity along with the stagnate conditions were the primary driver behind these elevated levels. Ozone stayed in the Good AQI range over the last several days, and we do not anticipate this changing anytime soon.

Overall, with stagnate conditions continuing this week, more Moderate AQI levels of PM10 (dust) and PM2.5 (smoke) are on the horizon. With no clearing event expected this week, values will likely increase throughout the forecast period. Ozone will continue to not be an issue this period.

Have a great day!
