“Small pieces of debris, that could be tree limbs or paper, lofted above 10,000 feet and that’s a sign that the tornado is a pretty decent tornado, or, I should say, a stronger tornado,” Friedlein said early Monday, noting how infrequently debris would be launched so high into the atmosphere. “The radar can sample that and tell it’s not raindrops or hail storms. That is unusual. It’s more rare that that happens.”
