Clear, sunny skies are sticking around but, temperatures are dropping a bit, look for highs in the upper 70s Sunday. That still put us around 10 degrees above normal for this time of year.

Mornings will stay cool, with overnight lows in the 50s, something to keep in mind if you're heading to a holiday lighting or parade event.

Next week, we're tracking two storm system That will finally bring winter wether to Arizona.

The first storm system moving into the Pacific Northwest that will swing down toward Arizona Monday night into Tuesday morning.

With that storm, the snow level will fall to around 6,000 feet and we could see one to two inches of snow along the Kaibab Plateau, some portions of the Mogollon Rim and the White Mountains.

The second storm system drops into Arizona by Thursday night and Friday. This system will bring much colder air and better chances for rain and snow. Stay tuned for details on this one as we get closer!
