No white Christmas after all. The storm system moving through Arizona tonight to tomorrow is a much weaker and faster moving than originally predicted last week. We will see some partly cloudy skies, winds, and possibly some light rain showers on Christmas eve. I don't anticipate any snow.
Snow is possible Wednesday Night – Thursday.
