Forecast Discussion:

Today and Thursday, high pressure will dominate the Southwest, causing winds in Rillito to be relatively light both days. As a result, PM10 (dust) should be mostly locally driven and stay in the Good Air Quality Index (AQI) category.

Then by Friday, the weather pattern over Arizona will begin to transition from the high pressure to low pressure. Winds will pick up out of the southwest in the afternoon. Since dust may be possible with these winds, PM10 has been increased and may reach the Moderate AQI category.

Finally, over the weekend, winds will increase much more out of the southwest as low pressure takes over the West. Thus, the risk for blowing dust will increase more, particularly on Sunday, which is forecast to see the strongest winds (20-25 mph with higher gusts). PM10 (dust) is forecast in the Moderate AQI category on Saturday and Sunday, highest on Sunday, though.
