alongside harry charles as travelling reserve, while london 2012 gold medallists scott brash and ben mahere forecast for saturday, so be prepared. the skies could turn dark almost at any time, thunder and lightning is possible too, and even the possibility of flash flooding in some areas. so this is what it looks like early on saturday morning — warm and muggy in the south, 16 celsius, a little bit fresher further north. we'll see one band of rain moving northwards through the morning, already giving quite a lot of rain in an initial space of time, but then come the afternoon, we'll see very heavy showers developing across the west country, the midlands, east anglia, the london area possibly, too. we could see, in the extreme case, up to 80mm of rain. now, that's a lot of rainfall in a relatively short space of time, so hence the possibility of flash flooding. temperatures will be typically around the low—20s further south, high teens in the north, and the showers and thunderstorms will probably linger at least in some areas into the evening hours as well. take care. this is bbc news with
