TUCSON - A second weather system will bring another round of valley rain and mountain snow in as many days.

After picking up 0.64" of rain and over a foot of snow on many mountain peaks yesterday we'll have another chance to add to those totals as a second wet weather system moves through the region. According to Meteorologist John Patrick, rain and snow totals do not look as impressive as yesterday but valley locations could pick up another 0.10"-0.25" and the mountains could see several inches of new snow.

As of 7am there were a few light showers around the Tucson metro and some snow flurries in the Catalina Mountains. The main band of precipitation was still in portions Western Arizona and heading east so expect occasional showers throughout the morning and afternoon hours.

A Winter Weather Advisory is in place for the Catalina, Rincon, and White Mountains of Graham and Greenlee Counties until 5pm this evening. With snow levels dropping to 5000 feet the higher elevations could pick up another 4 to 8 inches of snow through the day. A dusting of snow can be seen as low as 4000 feet.

Sunday looks a little drier with just a few left over snow flurries for the White Mountains, however, temperatures remain cool. Afternoon highs expected to remain in the mid 50s both Saturday and Sunday for Tucson which is about 5-10 degrees below average for mid-December.
