The "big bastard black one" spewing out lightning at 60 a second and thrrowing out grapefruit sized hail, torrential rain, tornadoes and such like is guaranteed to put an end to your barbeque /house /road /day with a tornado sending your bacon, prawns, sossiges barbeque, house, car and such like into the next country and is certain to spoil your day. And get a flurry of vids on Younyancat.
Like the one we got at 55N a few years back....
There's a nice positive lightning bolt on the clouds website. Can come from 20 miles away. One of these babies anywhere near you will spoil your day for sure :( You wouldn't want to be over a blue jet, sprite, elve, upward or whatever other ionospheric lightning bolt either. Dunno if the U2 or SR71 or leo spacecraft have ever been clobbered by one of these babies.
High energy physics $deity style.
Nuke as a supercell has the power of lots of 'em.
