Forecast Discussion:

This morning (Friday), satellite reveals upper-level clouds streaming over Arizona. This is indicative of upper-level moisture overhead. Of interest for this forecast though, will be the low-level moisture expected to move northward into the state Saturday and Sunday. This moisture will reintroduce rain chances to southeastern Arizona.

For Tucson, rainfall is in the forecast for both Saturday and Sunday. Tucson may see some modest amounts of rainfall, totaling up to a half an inch or more by Sunday's end.

Then by Monday, the moisture tap will stop, and rain chances will diminish.

Air quality-wise, light winds and cool mornings will be favorable for the local build-up of PM10 (dust) and PM2.5 (smoke) from local activity. This will be the general daily pattern. However, rain this weekend will help to reduce PM10 and PM2.5.

Overall, all pollutants are forecast in the Good Air Quality Index category each day. Check back on Monday for the latest.
