Heavy downpours and violent thunderstorms battered the UK this afternoon, with forecasters warning of further rain to come. The Met Office issued warnings for thunderstorms across large parts of the UK today, with heavy downpours that caused flooding and disruption in places. A warning is also in place for rain in the south on Thursday. Some areas could see heavy rainfall of 50mm in just a few hours, the Met Office warned. “Although some places will miss these heavy showers and thunderstorms, where they do occur they’ll be quite lively, bringing torrential downpours with 25 to 35mm rain falling in an hour and a few places seeing perhaps 40 to 50mm rain in a couple of hours," Met Office Chief Meteorologist Neil Armstrong said.
