Forecast Discussion:

Tucson is going on a breezy stretch this week. This is great for air quality! No significant buildup of ozone or windblown dust to consider for the forecast. The weather pattern providing daily Good to lower Moderate AQIs also brings maximum temperatures a degree or two below seasonable norms.

Concerning the extended, we are certainly on “monsoon watch” so to speak. The North American Monsoon season did officially begin on June 15th, but projections are not showing signs of the classic “Four Corners High” pattern favorable for moisture transport into Arizona until several days out, perhaps right near the start of July.
