Forecast Discussion:

This morning (Friday) is a nice and chilly one, and the third consecutive morning with low temperatures in the 40s. Moreover, once a low pressure wave finishes passing over Arizona today, lows will fall even more tomorrow--dropping into the 30s. For the most part, weather conditions will be relatively mild throughout this forecast period. Winds will be light and skies mostly sunny. High temperatures are also expected to return to the low 70s by Sunday. But Monday will be the exception, when winds are forecast to be breezy and out of the east.

Air quality-wise, both ozone and PM10 (dust) are forecast to remain in the Good Air Quality Index (AQI) category each day through at least Tuesday. But dust may be possible Monday morning and/or afternoon because of the stronger winds. That's why forecast hourly values for PM10 have been increased on Monday.
