Forecast Discussion:

The next storm system we are tracking is currently located over the Pacfic Northwest and is slowly moving toward the southeast. This system is expected to brush by Arizona to the north tomorrow into Friday. As this system moves by, expecting westerly breezes to increase Thursday afternoon into the 15-20mph range. Not expecting widespread blowing dust but we could see some isolated pockets. As a result, will raise PM-10 concentrations just slightly during the afternoon.

This system will also drop afternoon high temperatures into the mid to upper 90s tomorrow through the weekend.

By late Sunday into Monday, another area of low pressure will dive out of the Pacific Northwest toward Arizona. At the same time, some remnant moisture from Tropical Storm Lorena (currently located ~500 miles south-southeast of the tip of Baja) may move into the area producing a chance of showers and thunderstorms late Sunday into Monday. Will be watching trends closely as there are still many details to iron out.

Overall, air quality is forecast to stay in the Good AQI category through the forecast period.
