Forecast Discussion:
Air quality is in a much better shape this morning! Haze has now cleared the area. Breezier winds to finish the day on Tuesday have also effectively reset the airshed. Forecasted values have been adjusted downward accordingly. Although the air is cleaner at the moment, we are still falling into a less than ideal weather pattern for dispersion. Morning inversions and recirculation of pollutants remain likely the next few days, so an upward trend in PM10 and PM2.5 are being forecasted.Relief arrives by the weekend. The storm track may buckle enough to allow energy to enter the region from the north. That translates to faster winds and flushing the airshed again. That will be an important weather system for us to interrupt the stretch of stagnation, so we will be watching that one closely. Unfortunately, the change in air masses would be dry. On a side note, the last time measurable rain fell at Phoenix Sky Harbor was September 26th (0.05 inches)! Hopefully, rain comes back into the picture heading deeper into the autumn season.
