Clouds over Telford turn to grey bubbles in rare formation
It looked like something brewing in a witch's cauldron as the skies above Shropshire seethed with strange grey bubbles.
Shoppers stopped and looked skywards open-mouthed, and internet chatrooms were full of debate about the strange sight.
Today weathermen say the bubbles, seen in Telford on Saturday evening, were rare mammatus clouds, lobe-like clusters packed full of ice and rain that appear when thunderstorms are in the air.
This image was taken by Shropshire Star reader Bob Owen, shortly before a sharp shower.
He said: "It was only like it for two to three minutes and I just had to get a picture."
Another reader, Phil Spencer, said shoppers at the new Morrisons store in Lawley were stopped in their tracks
"Everyone was looking up and saying how odd it was," he said.
