Forecast Discussion:
Early this morning, a cold front pushed through central Arizona. Gusty winds associated with the front resulted in elevated PM10 (dust) around the Valley, and PM10 is still elevated at every monitoring site, as of 7:30 AM. As the morning progresses, PM10 levels should gradually improve. However, westerly breezes this afternoon may result in dust for more dust-prone areas. PM10 and PM2.5 (smoke) will reach the Moderate AQI category.
After today and through the rest of the week, we'll have a nice cooler air mass in place. High temperatures will hover in the 70s, possibly reaching the low 80s on Friday. Winds will also remain pretty light, save Saturday, when they start to increase again with the next approaching system. For the most part, PM10 and PM2.5 will stay locally driven, with highest levels expected in the typical industrial areas south/southwest of the Phoenix metro area.
Overall, PM10 and PM2.5 are forecast in the Moderate AQI category each day. Ozone is forecast in the Good category.
Check back tomorrow for the latest!
