Amonster winter storm that could bring ice, blizzard conditions, and travel disruptions – and will stretch 2,600 miles from coast to coast – was moving eastward Tuesday.
Swaths of the country could see over a foot of snow in the coming days, and parts of Minnesota are expecting 15 to 25 inches of accumulation. The National Weather Service in Twin Cities called the winter storm “historic” and said significant snow accumulation is expected to last until Thursday.
“There is a high probability that Minneapolis will pick up 18 inches of snow or more from the storm,” AccuWeather meteorologist Matt Benz said.
