Forecast Discussion:

The low pressure wave that brought widespread rainfall to Arizona earlier this week has moved on to the Northern Plains (as of Friday morning). Now, high pressure will be able to gradually build over the Southwest over the weekend into early next week.

For Rillito, chances for isolated thunderstorms will continue in the afternoons over the next few days since moisture will remain present. Clouds, locally heavy rainfall, and gusty winds will be possible in/around thunderstorms. But overall, we'll be in a warming and drying trend.

In regards to PM10 (dust), the main thing to note will be the possibility of briefly elevated PM10 levels from gusty winds or from morning local activity. But any rain would reduce airborne dust. Overall, PM10 is forecast in the Good Air Quality Index category each day.
