Many regions have been blanketed in snow after a winter storm system took more than a week to sweep across a large portion of the country from west to east, bringing deadly tornadoes to the South and blizzard-like conditions in other parts of the country. The major storm brought between 4 feet and 6 feet of snow to the Sierra Nevada mountain range, with 2 inches to 4 inches of flooding rain on the West Coast. Another 4 feet of snow was dumped in the northern Plains, with whiteout conditions and 40 mph winds, as well as snow drifts measuring up to 8 feet. The Northeast experienced a nor-easter, with up to 2 feet of snow falling in some regions and up to 2 inches of rain closer to the coast. Snow was still falling Sunday morning in northern Maine -- totaling up to an additional 6 inches to 12 inches in some spots. The system is expected to have fully exited into the Atlantic Ocean by Sunday night.
