A powerful winter storm was sweeping east from the Plains on Sunday, driven by what meteorologists describe as an intense cyclone, setting off a chain reaction of snow, ice, rain and severe weather expected to affect much of the country.
Snow and strengthening winds spread across the Upper Midwest on Sunday, where the National Weather Service warned of whiteout conditions and possible blizzard conditions that could make travel impossible in some areas. Snowfall totals were expected to exceed a foot across parts of the upper Great Lakes, with up to 2 feet (61 centimeters) possible along the south shore of Lake Superior.
In the South, meteorologists warn of severe thunderstorms expected to signal the arrival of a sharp cold front – sometimes referred to as a “Blue Norther” – bringing a sudden temperature drop and strong north winds that will end days of record warmth across the region.
Over the next 48 hours, the cyclone is expected to produce heavy snow and blizzard conditions in the Midwest and Great Lakes, freezing rain in New England, thunderstorms across the eastern U.S. and South, and widespread strong winds.
The storm is expected to intensify as it moves east, drawing energy from a sharp clash between frigid air plunging south from Canada and unusually warm air that has lingered across the southern United States, according to the National Weather Service.
It follows thousands of flight delays and cancellations across the Northeast and Great Lakes regions earlier this weekend due to snow, as thousands took to the roads and airports during the busy travel period between Christmas and New Year’s.
On the other side of the country, California was experiencing a fairly dry weekend after powerful storms battered the state with heavy rains, flash flooding and mudslides. At least four people were killed including a man who was found dead Friday in a partially submerged car near Lancaster, the Los Angeles County Sheriff’s Department reported.
