Discussion

Active weather will make its way into Arizona early next week, with a couple weak shortwaves migrating across the desert southwest. Though precipitation chances will be low, the decreased surface stagnation will lower particulates a little bit at the end of the forecasting period.

Before then, air quality trends will remain similar to what we've seen all week. No exceedances are currently expected, with PM10 being locally driven. Our hourly graphs above depict the timing of when particulates are expected to be most elevated and when levels are typically lower.

Have a great weekend and we'll see you on Monday!
