Once again... I was right in the middle of a major severe weather event and I don't even have to leave my home. What I saw today I don't think I will ever see again in my lifetime (in terms of the wind and the longevity) and I don't want to see it again. Lost my only tree the storm plus some roof damage. Eeek.

I've heard the term "mesoscale convective vortex" used before for strong MCS's that eventually develop their own circulation.


Smaller scale, not sure how similar this is


The North Carolina "Tornadocane"

Wow, Ed.......! It is very interesting! I have asked for those Mesoescale Convective Vortexes, in the threath we opened in our forum, and here is a very interesting reply, from a Spanish expert meteorologist on severe storms: http://www.vets.ucar.edu/vg/MCV/index.shtml

I know about MCV generated at the last stage of a mature MCS or a MCC, before to die. But not at the peak intensity of these structures.

When I saw that complex on radar the other day, I immediately thought it was an MCV but I haven't seen anyone else post about it in that context until now.
