A big winter storm is moving into Arizona on New Year's Day!
It will impact road travel and outdoor plans all across our state, so Sunday will be an ABC15 Weather Action Day. Take action to stay safe in this storm and limit your road travel across Arizona.
We could get around a half of an inch to an inch of rain across parts of the Valley. Since the ground is still wet from last week’s storm, that could lead to minor flooding in some spots (especially in and near washes).
Thunderstorms are possible on Sunday, too. Any storms that form could kick out wind gusts over 40 mph.
Small, soft ice pellets (known as graupel) are possible with any storms that move through.
Up north, the snow level will start out around 8,000 feet and gradually lower to around 5,000 feet throughout the day on Sunday.
It could go as low as 4,000 feet on Monday as snow showers linger along the Mogollon Rim.
Areas above 6,000 feet in elevation could see six to 10 inches of snow.
Winter Storm Warnings are in effect for Flagstaff, all along the Mogollon Rim and into the White Mountains through Monday morning.
Winter Weather Advisories are in effect for the are in effect for the Mazatzal Mountains, Pinal and Superstition Mountains, portions of Coconino, Yavapai and Gila County and southeastern Arizona through Monday morning.
Travel will be difficult in these areas with blowing snow reducing visibility and slick and icy roads.
Wind gusts could approach 40 mph in parts of the high country, too. That will lead to blowing snow and low visibility; treacherous travel conditions on Sunday.
Snow showers will linger along the Mogollon Rim into Monday. We'll also see another chance for a few rain showers in the Valley on Monday, too.
