12:45 a.m.

Severe weather including hail and at least one tornado have been reported in the Midwest as other areas dig out of a spring blizzard that shut down the Denver airport and closed hundreds of miles of roads.

Storms swept through northwest Arkansas late Wednesday, damaging or destroying several homes and severely injuring two people.

On Thursday, the National Weather Service confirmed a tornado touched down on the southeast side of Lake Charles in Louisiana, damaging a home.

Elsewhere, a hailstorm broke windows in northern Texas, and snow fell in Minnesota. Forecasters predicted another 1 to 4 inches of snow across most of Wisconsin on Thursday.

Denver International Airport reopened Wednesday evening, but by then most of the day's flights had been canceled. Travelers trying to fly out Thursday faced long lines during the already busy spring break travel week.

Travelers trying to fly out of Denver are facing long lines a day after a spring blizzard shut down the airport.

The number of stranded travelers during an already busy spring break travel week made for long waits at airline check-in counters and security on Thursday.

The storm also brought heavy and blowing snow to parts of Wyoming, South Dakota, Nebraska, Iowa, Minnesota, Wisconsin and Michigan. Up to a foot of snow fell in the southern Twin Cities.

It is still snowing in Michigan, where high winds prompted Mackinac Bridge officials to require that some bigger vehicles cross under escort.

The snow shut down long stretches of Interstates 25, 70 and 80 in Wyoming and Colorado on Wednesday but they are back open except for portions of I-70 in eastern Colorado.
