The storm has already dropped nearly 2 feet of wind-whipped snow on parts of South Dakota. A handful of tornadoes have been spun up, with more forecast to come. Several tornadoes were confirmed early Tuesday in Tennessee and Mississippi. The National Weather Service declares an “enhanced risk” of dangerous storms. About three dozen record highs could be threatened Tuesday, centered on the Ohio Valley.
As many as 100 record warm low temperatures could fall in the eastern U.S. Wednesday morning. Thinking about heading toward Sioux Falls today?
