User blog comment:Bengalsfan/Albany tornado given a preliminary of EF2/@comment-26074320-20170123232222/@comment-27225426-20170124113741

No, a mile wide EF2 is possible, and I can give some good examples.

July 27, 2015: A mile-wide EF2 tornado touched down in Manitoba and tracked into Ontario.

May 19, 2015: An EF2 tornado touched down near Snyder, Oklahoma, a mile-wide but only causing EF2 damage.
