Reader David Eaton sent in this picture of an unusually-shaped cloud over Corby.
He said: “I was travelling home from Shire Road at 7pm when I saw a funny storm cell with cloud rotating at the bottom.
“I made my way to a better viewing point from the Earlstrees estate and I would say it was just beyond the Rockingham Speedway and the funnel cloud was traveling from north to south.
“Hope you enjoy these picture.”
