A winter weather advisory is in effect until 8 p.m. Friday as another winter storm heads toward Northern Arizona. The National Weather Service says to expect two-to-four inches of snow in most places with up to seven inches of snow possible. For Flagstaff, expect two-to-four inches of snow, while Doney Park and Williams could also see two-to-four inches before the storm moves out tomorrow night. We will see gusty winds at times as well. We will return to sunny skies for the weekend until another storm arrives Monday night.
