Forecast Discussion: Due to an early break in the cloud cover and weak winds in the Valley, ozone was able to pool near the Central Phoenix area. In addition, the lack of gusty winds during the afternoon hours prevented a clearing event. Thus, concentrations peaked in the upper Moderates. Looking ahead, we've got some weather activity headed our way since moisture levels in the atmosphere remain relatively high. Tomorrow looks to be a similar situation as well. However, most of the activity will be forced eastward and contained near the higher terrain as a southwesterly flow sets up. Ozone should back down as gusty winds from outflows and incoming cloud cover make it to the Valley this afternoon. However, once clear skies return on Sunday, concentrations can begin to increase. As for PM-10, gusty outflows today and tomorrow afternoon can result in blowing dust activity. Thunderstorms originating over Pinal County hold a potential for picking up dust. Check back on Sunday for a look ahead at next week's weather and air quality. Until then, have a great weekend! -P.Patel
