As many as 11 million people from California to Wisconsin are under winter weather advisories Monday due to a massive storm that has already dumped up to 4 feet of snow across the Sierra Nevada. The storm, expected to bring both snow and severe weather, is making its way into the Rockies and the northern Plains on Monday, where blizzard-like conditions are expected. Up to a foot of snow is expected to hit the Rockies, with winds gusting up to 50 mph. The risk for severe weather Monday is centered around southwest Kansas and the Oklahoma panhandle, where damaging winds up to 60 mph, large hail and a few tornadoes are possible. By Wednesday, the threat will shift east, where residents of New Orleans to the Florida panhandle are at risk for damaging winds, large hail and a few tornadoes.
