Forecast Discussion: A few thunderstorms moved through the Valley again yesterday evening. Sky Harbor reported 0.13" of rain with wind gusts up to 41 mph. The winds yesterday were strong enough to kick up some dust even with relatively stable soils from recent rains. A few PM-10 monitors did reach into the Moderate category for their 24-hr average. There will continue to be potential for evening thunderstorms today and tomorrow as we continue to have a good amount of moisture in the region. Fortunately, the more rain we receive the less likely a major dust event will occur. Ozone looks like it will begin improving after several days of elevated concentrations. Stronger mid-level winds associated with an approaching trough will help with ventilation which will prevent ozone from pooling up. Overall, this coming week is looking like it will be a fairly good air quality week. Check back tomorrow for more. Until then, have a good day! –R.Nicoll
