PHOENIX — Our first BIG winter storm of 2023 is moving through Arizona.
We're tracking widespread rain, snow, thunderstorms, gusty winds and another big dose of cold air across Arizona.
RADAR: Track rain, winter weather across Arizona here.
This storm is impacting road travel and outdoor plans all across Arizona, so we're in ABC15 Weather Action mode. Take action to stay safe in the storm and limit travel across our state.
Phoenix set a new rainfall record for New Year's Day with 0.43 inches of rain at Sky Harbor. That broke the previous record of 0.22 inches set in 1906.
Thunderstorms with lightning and small hail have been in the mix, too.
Up north, the snow level is gradually dropping to 4,000 feet with six to ten inches of snow above 6,000 feet, three to six inches above 5,000 feet and about an inch above 4,000 feet.
Winter Storm Warnings are in effect for Kaibab Plateau, Flagstaff, all along the Mogollon Rim and into the White Mountains through Monday morning.
Winter Weather Advisories are in effect for the Mazatzal Mountains, Pinal and Superstition Mountains, portions of Coconino, Yavapai and Gila County and southeastern Arizona through Monday morning.
Wind gusts at 30 to 40 mph in parts of the high country are leading to blowing snow and low visibility and those treacherous travel conditions will continue overnight.
Snow showers will linger along the Mogollon Rim throughout the day Monday. We'll also see another chance for a few showers in the Valley, too.
Then, another storm system will move in on Tuesday. Rain and snow chances will ramp up again across Arizona, so stay tuned for more details on this one as we get closer.
