Behind the view of flying trees and roofs there was quite a good display of iridescent (I think they are) clouds this evening.

Saw something very similar here towards the west.

Have also seen photos from Lincolnshire. Wish I'd been aware and had a look outside. Ah well, in 199? they were sensational.

These are polar stratospheric clouds (PSCs), a.k.a. nacreous clouds. My news and social feeds are full of pictures of them remarkably far south (Buckinghamshire, for example). Or perhaps not so remarkably when you look at how very cold (and moist) the stratosphere is over the UK due to circumpolar vortex displacement (in turn due to ongoing stratospheric warming Pacific-side). Temperatures are between -80 and -85C at 50hPa, for example, and below -85C at 30hPa (and PSCs form below -78C):

Not as spectacular as Trevor's though.

I spent my school years there, saw my first atmospheric phenomena and
my first tornado.

Still visible this morning in North Yorkshire. They look like they are
nacreous clouds from the sculpted shapes and strong irridescence.

It appears the strong winds have punched some water vapour up into the
stratosphere. I watched them evolving as it grew light this morning.

Pictures will follow shortly.

Still visible (just) in daylight at the moment 11am 2/2/16.

Low fast moving clouds interfering slightly just as they did in the
previous widespread display of Feb 16 1996. Conditions were as I recall
somewhat similar with a very strong surface winds although the clouds
this time were not as obviously lenticular in nature.
