Forecast Discussion: [View the ADEQ Hourly Forecast for Phoenix]
There is a low pressure system sitting off the coast of northern California forecast to move down the coast before turning eastward over Arizona. There will be light breezes the next few afternoons as well as a cooling trend associated with this system. It's even beginning to look like we will get some light showers with this system, with best chances for Wednesday afternoon. Under this more active weather pattern, we forecast air quality to be pretty good. Ozone is forecast to stay in the Good AQI range through the week. PM10 may manage to reach low Moderates today and tomorrow with calm mornings, but once the rain arrives on Wednesday, PM10 levels should lower quite a bit. PM2.5 should also stay comfortably in the Good AQI range through the week.
