Forecast Discussion: A weak trough will remain over the Southwest for the next several days. Strongest winds are expected in western Arizona; winds in central Arizona are looking to be lighter. With high resolution models forecasting stagnant conditions in the Valley on Friday and "back-trajectories" (wind traces) suggesting ozone containment in the Valley, an ozone High Pollution Advisory (HPA) has been issued for Friday. It is possible that this ozone HPA could be extended into Saturday due to a continuation in stagnant conditions. PM-10 is a little bit more uncertain. A southerly, monsoonal flow will make thunderstorms possible in southern and central Arizona on Friday and Saturday. Thus, there is a potential for outflow winds to impact the Valley from the south. Since Pinal County is one of the drier areas in central Arizona, any outflows from that area could transport dust into the Valley. However, any rain following the outflows would help to shut down dust. PM-10 is forecast to be in the Good AQI range for now. Check back tomorrow for the latest. Until then, have a good day! –M.Graves Last Update: Thursday, August 25, 2016, 9:31 AM
