/INCLUDING A TORNADO/ OVER SWRN AR.

I always sorta wonder if events like these will pan out. When you get these giant QLCS events it seems like the tornado numbers don't pan out as expected most of the time. It is impressive helicity numbers but it's not easy for embedded storms to spin within a line strongly

It's going to be a while until this becomes a QLCS event. Everything is breaking out of a line and going discrete.
