Forecast Discussion:

A storm system is moving across Arizona this morning, but you might not have noticed it as it lacks moisture. It will bring breezy north-northeast winds to the region later this morning into the afternoon; however, that will be about it for impacts. Another fast-moving system will sweep through Arizona on Saturday but again, expect very little in the way of noticeable changes to the weather.

Things will become more interesting by the first part of next week. A storm system is expected to develop along the West Coast and move into Arizona late Monday into Tuesday. The million-dollar question with this system is how much moisture it will have. If it can stay right along or just off the coast, it will have more moisture than if the track pushes east, moving the system overland as it drops southward. Right now, going with a 50/50 mix, meaning there will be slight rain chance late Monday into Tuesday. Right now, we are not expecting a lot of rain, with most locations staying below a quarter inch, but we will undoubtedly monitor conditions closely.

As for air quality, forecasting ozone, PM-10, and PM-2.5 to stay in the Good AQI category through the forecast period.
