On a day of unsettled weather photographer Mark Bentley took these spectacular pictures of a storm brewing in West Oxfordshire.

Mr Bentley went storm hunting in the roads around Brize Norton on Saturday and came back with photos of low-hanging black clouds and an amber sky.

Many parts of Oxfordshire experienced heavy downpours, hailstones, thunder and lightning on Saturday after days of warm weather.
