Midwest, eastern U.S. bracing for Arctic blast, subzero temps

The Midwest and eastern parts of the U.S. on Sunday braced for Arctic temperatures that were expected to arrive during the next few days.

A mix of precipitation on Saturday that included snow, ice and rain affected a swath from the Oklahoma Panhandle - where several inches of snow were in the forecast - to southern New England, where up to a quarter-inch of ice is possible in the eastern Berkshires.

Freezing rain and ice factored into numerous accidents in Michigan, Pennsylvania and Ohio and threatened an outdoor hockey game in Toledo.

And parts of the southern U.S. saw heavy rain and thunderstorms, leading the National Weather Service to issue tornado watches and warnings in Mississippi and Louisiana and a flash flood watch for portions of Arkansas.

The weather service reported at least two confirmed tornadoes in Mississippi. Greg Flynn of Mississippi's Emergency Management Agency said homes were damaged in several counties, power lines were downed and there were reports of flooding.

"Thankfully, in all of this, there are no injuries reported anywhere," Flynn said.

Meanwhile, blowing and drifting snow was a problem in the northeast Colorado plains, while a blizzard warning was issued for northern North Dakota and Minnesota. Winds between 30 to 40 mph blew snow that fell overnight in the Red River Valley, weather service meteorologist Tom Grafenauer said.

That area will be the first to feel the effects of a strong cold front, he said, with temperatures reaching 20-below and wind chills approaching minus 50 by Sunday morning.

By Tuesday, parts of the Midwest will see below-zero temperatures, while lows will reach single-digits along the East Coast. The chilly weather is even expected to move as far south as New Orleans.

Meteorologist Ryan Maue of the private Weather Bell Analytics has called it "old-timer's type of cold."
