The low pressure system is now off the coast of central California and will dip down a little further south before turning eastward over Arizona. This system will provide good ventilation over the next several days, which should help keep pollution levels down. We're also looking at potential showers as this system moves overhead. Best chances for rain in the Phoenix area will be Wednesday afternoon, with slight chances again on Thursday. Overall, we don't expect to see much rain in the Valley, but it should still be enough to help out the air quality.

With this system moving through this week, ozone levels are forecast to stay in the Good AQI range through the forecast period. PM10 levels are once again elevated in parts of the Valley this morning due to industrial work activities, but like yesterday, it looks like we should just barely stay in the Good AQI range. Looking ahead, the expected rain will help lower particulate levels further into the Good range Wednesday and Thursday, before beginning to trend back up a little. PM2.5 should also remain comfortably in the Good AQI range through the forecast period.
