A day that will live with storm chasers forever.... The beginning of the clip shows us nearly driving into the 2.6 mile wide EF-5 near Reno Road and Chiles. We started getting 80-90 mph winds out of the north before we retreated only to encounter the Tuttle tornado later on. The rest of the clip shows us outrunning the tornado near Mustang, OK with measured 90 mph winds.
