PHOENIX — Back-to-back storms are moving into Arizona this week with more wind, rain and snow.

Tuesday and Thursday will be ABC15 Weather Action Days as these storms potentially impact road travel, events and outdoor activities.

The first storm will bring chances for rain to the Valley on Tuesday night, mainly between 5 p.m. and 2 a.m. There is a chance to see a quarter to a half an inch of rain in parts of the Valley.

Up north, the snow level will be between 5,500 and 6,000 feet in elevation. Flagstaff could pick up one to three inches of snow.

Winter Weather Advisories will be in effect from Tuesday evening until mid-day Wednesday for areas above 6,000 feet along the Mollogon Rim. Two to six inches of snow is possible there as winds gust over 30 mph.

A few lingering showers could impact parts of our state on Wednesday. Then, an even stronger storm moves in on Thursday.

Early estimates show another quarter of an inch of rain will be possible in parts of the Valley Thursday afternoon and evening.

Up north, the snow level will plummet to 3,500 feet by midnight, potentially bringing more snow to the mountains north and east of the Valley.

Early estimates show that Flagstaff could pick up an additional four to eight inches of snow on Thursday and Friday with this storm. These numbers can, and likely will, change as we get closer. So, stay tuned for updates.

There's also another quick-moving storm system that may clip into northern Arizona on Saturday keeping rain and snow chances going for many areas. We'll update you on this one as we get closer.
