Good example of anvil Cumulonimbus?

[[2574]]

Photographed on Saturday morning: https://www.dropbox.com/s/xkrnqbfvwdc9au3/Anvil cloud.jpg

Doesn't look high enough (nor angry enough!) for cumulonimbus but is displaying classic anvil profile. Any comments?

It looks a long way away,it could be miles high and full of hailstones! Nice photo well spotted. It's always difficult to judge the size/height of clouds but you can see it is a fair bit further away than that dark grey stuff. Is the top face of the anvil showing the top of the cold air mass perhaps? Jerry

Comparing the elevation of the cloud with that of the Eddystone Lt (161ft high, 12 nm distant), and assuming it is normal Cb height (at least 22,000ft), would give a distance of approx 70-80nm, taking into account curvature of the earth. This would coincide with the trough just north of Brittany on the synoptic chart 0900Z Saturday.

East Sussex: We got hailed on during the middle of the afternoon that day by a cloud which didn't look anything like big enough. Reports from pilots yesterday were that their XC flights were cut short due to the cold at even quite low levels.

The instability over the last few days has been breathtaking, with some fantastic cloud formations, by a hair's breadth not quite enough for thunder & lightning. On Friday there was even a patch of snowfall...
