Forecast Discussion:

Today a low pressure wave will slowly migrate through the Southwest, resulting in breezy winds out of the west-southwest for Rillito. Then by tomorrow, Arizona will be caught in between an approaching high pressure and the low pressure. Winds will shift to out of the northwest and be somewhat breezy again.

During this time, elevated PM10 (dust) may be possible in the afternoons because of the winds, especially today. PM10 is forecast in the Moderate AQI category today.

Then by Wednesday, the high pressure will take over the region, resulting in increasing temperature trends and lighter winds. PM10 should be mostly locally driven and stay in the Good AQI category.

Finally, on Friday, winds are forecast to increase out of the southwest as the weather pattern over the region begins to change again. PM10 may be elevated again in the afternoon, but is still forecast in the Good AQI category.
