I had that kind of mess after the Easter weekend  storm in 2007, basically our wheat was a total loss , it made about 5bpa  50# or less test weight, it was about 20 degrees for 2 nights and we had less snow in 2007. Our wheat in 2007 was mostlly still in the  boot just a few heads showing, most of it just layed down and died it tired to  grow new tillers but they did not produce much.
