System brings blizzards, threat of tornadoes to Midwest

MINNEAPOLIS — A potent, slow-moving spring storm system that’s expected to persist through the weekend began raking the Plains and Midwest on Friday, bringing blizzard conditions to South Dakota and the threat of tornadoes from Texas and Louisiana north all the way to Iowa.

The huge storm, packing enough energy to cause widespread disruption, isn’t unprecedented for April, said Jake Beitlich, a meteorologist with the National Weather Service in Chanhassen, Minnesota.

“We do get pretty powerful systems coming throughout the Midwest, and on the cold side we do get snow. And this one is particularly strong. So we do have a lot of moisture with it, and a lot of energy,” Beitlich said. “Over the next 24 hours cold air is going to get wrapped into this system and we’re going to see a band of heavy snow develop from southwestern Minnesota through northern Wisconsin.”

Blizzard warnings stretched from northern Kansas across most of Nebraska and South Dakota into southwestern Minnesota and northeastern Iowa, with winter storm warnings and watches covering most of the rest of Minnesota, Wisconsin and Michigan. Heavy snow already blanketed parts of western Kansas, Nebraska and South Dakota by early afternoon Friday, closing major highways in South Dakota and many roads and highways in western Nebraska — including a 200mile stretch of cross-country thoroughfare Interstate 80 from North Platte west to the Wyoming border. A road conditions report said most roads in the Nebraska Panhandle to east of Valentine in the northern part of the state were impassable because of heavy snow cover.

The snow also led officials to shut down the Sioux Falls, South Dakota, airport Friday afternoon through Saturday night.

Snow, freezing rain and high winds were expected through Saturday night, with heavy ice accumulations in parts of Michigan through Sunday morning.

A swath of southern Minnesota including Minneapolis though northern Wisconsin was expected to get 8 to 12 inches of snow or more. Parts of northern Nebraska could get up to 18 inches, with up to 12 inches in northwestern Iowa. Wind gusts of up to 50 mph will make travel hazardous.

The National Weather Service’s Storm Prediction Center in Norman, Oklahoma, issued tornado watches Friday for eastern Texas and western Louisiana, moving up through eastern Oklahoma, Kansas, Arkansas and into Missouri and Iowa.
