Whacko OT: Longest mare's tail cloud I've ever seen

[winchman]

Over the southeast and the Atlantic Ocean:



The area is covered by a large high pressure system.

I'll bet you there's a bigger one over British Columbia, and more accurate............

That is where the current location of the jetstream is.

It's a long string of clouds along a pressure gradient but that doesn't make it a Mare's Tail cloud. To qualify as a Mare's Tail the clouds must be cirrus clouds at an altitude of 4 to 8 miles. They are also small individual clouds that are very thin because they are composed of ice crystals. They don't cover bands 200 miles wide with a complete overcast. That image is taken in infrared and does not show what the visible clouds look like. It is actually a temperature map of the atmosphere.

The whole thing is a mare's nest.

it's clearly not a mare's tail, that would imply a horse of quite another color.........
