Met Office predicts UK could experience temperatures of up to 33C, with hot weather expected over the weekend and into the start of next week. South east Wales could reach temperatures of 27-30C, while the south west of England might see highs of 33C. The warm spell is attributed to the strengthening jet stream caused by Tropical Storm Debby. After the hot weather, unsettled conditions are expected to return, with Wales turning cooler and wetter by Tuesday.
