Midwest blizzards reach 'bomb cyclone' intensity

A strengthening bomb cyclone barreled across the northern U.S. on Monday, unleashing severe winter weather in the Midwest as it took aim at the East Coast.

The storm brought blizzard conditions, treacherous travel and power outages to parts of the Plains and Great Lakes on Monday as sharply colder air, strong winds and a mix of snow, ice and rain swept through.

Forecasters said the storm intensified quickly enough to meet the criteria of a bomb cyclone, a system that strengthens rapidly as pressure drops. The sharp cold front left parts of the central U.S. waking up Monday to temperatures as much as 50 degrees colder than the day before.

All that wind and snow created “a pretty significant system for even this part of the country,” said Cody Snell, a meteorologist with the Weather Prediction Center. Dangerous wind chills plunged as low as minus 30 across parts of North Dakota and Minnesota.

In Iowa, blizzard conditions eased by Monday morning but high winds were still blowing fallen snow across roadways, keeping more than 200 miles of Interstate 35 closed. State troopers reported dozens of crashes during the storm, including one that killed a person.

Forecasters expect the storm to intensify, fueled by a sharp clash between frigid Canadian air and lingering warmth across the southern United States.
