Forecast Discussion:
Upper-atmospheric winds will be quite active over the Southwest this week, culminating in the development of a strong jet stream over Arizona by Thursday. At the ground, this pattern will mean daily breezy winds in Tucson. Winds will be out of the southwest today and Wednesday, out of the west on Thursday, and out of the west-northwest on Friday and Saturday. And winds are generally looking to be at least 15-20 mph with higher gusts today through Friday.Air quality-wise, the discussed winds are expected to help limit how high ozone will be able to reach in the afternoons. As a result, ozone is forecast in the Good Air Quality Index (AQI) category each day.
Both PM10 (dust) and PM2.5 (smoke) are also forecast in the Good AQI category each day. However, we can't rule out the possibility of pockets of blowing dust in desert areas because of the winds. Plus, elevated PM10/PM2.5 levels may be possible in the morning/evenings from local activity under light winds.
