The storm track will shift south over the next 5-7 days with heavy snow expected across Utah, Arizona, and the San Juans in Colorado, while Tahoe will start to pick up some good snow starting on Monday and continuing through much of next week. In the East, snow showers will continue across New England on Friday-Saturday, followed by a storm that will impact the Mid-Atlantic on Monday-Tuesday.
