Forecast Discussion:
Over the past several days, ozone levels have stayed in the Good Air Quality Index (AQI) in Tucson. We can thank an active weather pattern and the lack of any strong high pressure for this.Looking ahead, a low pressure wave will slowly migrate through the Southwest today, giving Tucson it's coolest day of the week (low 90s) and breezy winds out of the west-southwest. Then by tomorrow, Arizona will be caught in between an approaching high pressure and the low pressure. Temperatures will remain in the low 90s, while winds shift to out of the northwest.
During this time, ozone is expected to remain in the Good AQI category because of the winds. Also, locally elevated levels of PM10 (dust) may be possible, especially for dust-prone areas. However, PM10 is forecast in the Good AQI category.
Then by Wednesday, the high pressure will take over the region, resulting in increasing temperature trends and lighter winds. Ozone is forecast in the Moderate AQI category Wednesday and Thursday. 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. For now, ozone is forecast back in the Good AQI category. PM10 may also be elevated in dust-prone areas again.
