Forecast Discussion:
Dry and mild conditions continue through Thursday along with light winds. On Friday, a weakening weather system passing mainly through far northwest Mexico will bring a chance of showers and slight chance of thunderstorms to the Tucson area with rain chances tapering off Saturday morning. Breezy to windy conditions can be expected Saturday afternoon.
Average pollutant levels yesterday remained within the Good range and that is expected to continue the rest of the week. Of note, Particulate levels will trend slowly upward from day to day through Thursday before beginning to improve at the end of the week with the passage of the weakening weather system. Ozone is also anticipated to be at its best by Saturday.
