Titan partner @ghosttrainphoto captured this wall cloud taking shape near Akron, CO earlier this week. This wall cloud was the first step in the process towards this supercell coming oh so very close to producing a tornado. Anytime you see persistent rising motion like this under the base of a supercell, you have to start looking for the other pieces of tornado formation to come together, like the RFD cut/horseshoe coming around and increasing rotation in the wall cloud. #tornado #wallcloud #weather #science #Colorado
