At one point, the line of storms stretched from Canada to the Gulf of Mexico. It dumped snow in the north-central and northeastern United States and torrential rain in the Ohio and Mississippi valleys, and brought tornadoes in the Deep South.
Three people were killed in separate incidents in Missouri, Mississippi and Nebraska.

In Mississippi, one person died when a tornado destroyed a steel building along a highway in Kemper County, on the Alabama border, on Thursday, the National Weather Service said. It rated the storm an EF3, meaning the tornado had winds of between 136 and 165 mph and was capable of severe damage.
Five people were hurt across Mississippi, state emergency management agency said. At least seven counties in Mississippi and four in Alabama suffered damage, officials said.
Georgia's emergency management agency reported trees down in several counties Thursday night.
A weak tornado snapped large limbs and caused power outages around Slidell on Louisiana's Gulf coast, according to the National Weather Service.
