Forecast Discussion:

It will be more of the same this week in the Tucson 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!

Overall, with calm conditions continuing this week, more Good 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!
