Forecast Discussion:

The weather system that brought rain to the region yesterday has moved east of the state but did leave behind some decent rainfall totals. Tucson International Airport picked up 0.17 inches, and locations in the foothills across the eastern portion of Tucson picked up just over 0.30 inches.

The tail end of a weather system is sweeping through the state this morning, bringing some windy conditions to the northern portion of Arizona. This system will not have much of an impact on Tucson, with the only noticeable influence being afternoon high temperatures staying in the mid-60 today.

High pressure will quickly build into the area this weekend, which will mean light winds, mainly clear skies, and temperatures rising back into the 70s.

The only wrinkle in the forecast will be the potential for some easterly winds to develop Sunday into Monday as some weak disturbances begin to breakdown the area of high pressure.

Air quality is forecast to remain in the Good AQI category through the weekend into the first part of next week.

Have a great weekend!
