283mph gate to gate velocity at 5,000 feet above the ground in MO near Caruthersville, making this the strongest tornadic gate to gate couplet in Doppler radar history. Previous was a tie between Greensburg KS 2007 EF5 and Tuscaloosa AL 2011 EF4 at 280mph. So far hit 3 states. pic.twitter.com/NA1dOQcmn1
