Forecast Discussion:
This Friday morning is a bit cooler than the past few mornings, thanks to a cold front that moved through last night. Clearing skies have helped, too.
Looking ahead, this weekend will be characterized by a cooler pattern. A low-pressure wave/circulation will maintain the cooler air, only allowing high temperatures to reach the upper 70s today through at least Sunday. Then by Monday, higher pressure will move into the region and cause temperatures to warm up again. As for winds, we'll remain mild compared to the past couple days, with some light afternoon breezes possible today and Saturday. Rain chances will be absent through the period.
Regarding PM10 (dust), rain from earlier this week will help to limit PM10 levels. However, locally elevated PM10 levels will be possible in the mornings/evenings.
For now, PM10 is forecast in the Good AQI category each day.
Check back again on Monday for the next Rillito Air Quality Forecast.
