Forecast Discussion:
This morning (Friday), the weather pattern over Arizona will transition from high pressure to low pressure. As a result, winds are forecast to pick up out of the west-southwest this afternoon. In regards to air quality, ozone is still forecast in the Moderate Air Quality Index (AQI) category today since there will be time in the morning for ozone to build up locally. Pockets of dust may also be possible in the afternoon, but PM10 (dust) should easily stay in the Good AQI category.Looking ahead, Saturday through Monday, the jet stream will dig into the Southwest. This will result in breezy conditions each day, with winds generally out of the southwest. The good news is that these winds will help to reduce ozone levels. However, on the flip side, winds will increase the potential for wind-blown dust. Therefore, hourly forecast PM10 levels have been raised each afternoon. PM10 is still forecast in the Good AQI category, though.
Finally, by Tuesday, winds are forecast to weaken as the jet stream begins to exit the region. Ozone should trend upwards, while PM10 (and PM2.5) become mostly locally driven again.
