Tuesday 26th May, c. midnight
"On the Tuesday following Whit Monday in 1931 at about 20h00, a violent thunderstorm occurred in Pontnewydd, Gwent. The storm lasted eight hours and caused considerable damage. At about 00h00, the witnesses (two boys) saw a bluish ball about the size of a football strike a brick wall and bounce onto the road, disappearing in a shower of sparks. Next morning, they found a hole in the wall and a small crater in the road."
BUFORA V7/N3 listed this as one of their likely confirmed ball lightning cases in 1978 - under the misspelling 'Portrewydd' - so it has since been included in various write ups of the phenomena.
