Forecast Discussion:
Tucson received a decent amount of rain with this past storm system. Officially, Tucson International Airport measured 0.16 inches of rain; however, other locations in the city recorded much higher totals. In fact, gauges in the Catalina Foothills measured 0.75 inches to over 1.25 inches!For today, the storm system is moving eastward so for the rest of the morning only anticipating a slight chance of some light rain. With that said, moisture will continue streaming overhead so expecting plenty of clouds.
Tomorrow into Sunday afternoon, expect beautiful weather with mostly sunny skies and well below average high temperatures in the upper 50s. By Sunday evening into Monday, another storm system will sweep into the state. This storm system will renew rain chances across the region and usher in much colder air.
The best chance of rain right now looks to be late Sunday night through Monday afternoon. Rainfall totals are forecast to be in the 0.10-0.25 inch range so much less compared to last storm. The big story will be very cold temperatures, with high temperatures on Monday and Tuesday in the low 50s with low temperatures on Tuesday and Wednesday morning at/below freezing.
With an active weather pattern continuing, forecasting both PM-10 and ozone to remain in the Good AQI through the forecast period.
Have a great weekend!
