Strongest tornado since August 19. Hopefully everything comes to an end soon so that everyone can have a Merry Christmas without the severe weather grinch...

I'm not sure if they will do storm surveys today being Christmas Day though, especially since it doesn't appear there were any more high-end tornadoes.
