Forecast Discussion:

The storm system that brought strong winds to portions of the state yesterday is now moving east, but today we will still feel the impacts of the system in the form of cool air, with afternoon highs forecast to be in the upper 60s.

High pressure will begin to build back over the region, and at the same time, a weak disturbance is expected to move into the state tomorrow from the southwest; however, the only impact will be an increase in high clouds.

By Thursday, another trough of low pressure will drop down the West Coast and increase southwest breezes in Phoenix. As the storm brushes by to the north, it may be able to draw up some moisture from the south and result in a slight chance of rain late Friday into Saturday. We are not expecting a lot of rain out of this system, but it will be something to watch.

As for air quality, the primary pollutants to watch will be PM-10 (dust) and PM-2.5 (smoke). With mainly calm winds, cooler temperatures, and stronger inversions during the overnight period, expecting both PM-10 and PM-2.5 to rise, resulting in the 24-hour average being in the Moderate AQI category through the forecast period.

Make it a great Tuesday!
