A storm system could start to impact Arizona beginning Monday evening, but the main brunt of it moves in on Christmas Eve for the Valley.
Tuesday morning through the early afternoon appears to be the most active for the Phoenix-Metro with widespread rain, which will impact the morning commute and Christmas Eve services and events.
Rainfall amounts in the Valley will range from 0.50" to 1.00" with higher amounts possible in the Foothills.
The storms will also produce snow for northern Arizona. Amounts now are expected to be anywhere between 4" to 8" above 6,000 feet through Christmas Day. The areas impacted include Flagstaff, the Mogollon Rim, and the White Mountains.
Scattered thunderstorms are possible Christmas Day for the Valley as well, with pockets of storms bringing heavy rain, lightning, and small hail.
Although it's a week away, models are hinting at ANOTHER winter storm that will move in sometime next Thursday and Friday, bringing more rain and mountain snow to Arizona. We'll keep you posted on specifics as we get closer.
