Spectacular mammatus clouds spotted over Chesterfield after wind and heavy rain
These incredibles pictures, taken by Gareth Clark, show strange shaped clouds in the sky over Chesterfield after wind and heavy rain battered the town.
The so-called mammatus clouds were captured over Brampton on Thursday evening, with rain falling shortly after they rolled through the sky.
A Met Office weather warning was in place for much of the day as strong gusts accompanied by heavy and blustery showers hit Derbyshire.
Mammatus clouds are commonly found in the vicinity of thunderstorms and are formed by descending air in the cloud.
The clouds are sometimes described as looking like a field of tennis balls and appear to have pouch-like protrusions hanging down.
It’s from this shape that they get their name, through the Latin word "mamma", meaning udder or breast.
They are said to be some of the most unusual and distinctive clouds formations, and can extend hundreds of miles in any direction, remaining visible in your sky for perhaps 10 or 15 minutes at a time.
