Forecast Discussion:

With the exiting storm system, we are back to calmer winds and a drier environment. We would have like to have seen greater amounts and coverage of precipitation in southeastern Arizona. Besides the nearby mountains where at least a quarter inch is estimated to have fallen, Tucson topped out at only trace amounts (e.g., at the Tucson International Airport), so not much at all. The presence of the passing low pressure wave did have a positive effect on our air quality, though. More positive influence from a dip in the jetstream over Arizona comes between Sunday and Monday afternoons. Daytime breezes are good for trending forecasted pollutants lower after a few days of stagnation.
