Although damage was heavy throughout Lawrence, indicating a tornado, this morning's storm has not been declared an "official" tornado, according to Jennifer Schack, 6News meteorologist.
"We're not going to know for awhile because there was not a trained spotter giving us reports," Schack said.
She said there were also no radar indications of a tornado.
Schack said a trained spotter in the Reno area did report a possible tornado, which was reported by the National Weather Service.
Schack said that winds of up to 76 mph were reported in the city of Lawrence at the height of the storm.
"That's high enough for a microburst or a weak tornado," Schack said.
