away. hello. for some of us, it's been another warm and very sunny day, particularly across parts of scotland, northern ireland, and northern england. this was falkirk earlier on this afternoon. lots of blue skies and sunshine. for others, we started the weekend with thunderstorms, torrential rain and frequent lightning. and all of us will see a change to something cooler and wetter in the week ahead. and it's all down to the jet stream, very active in the atlantic, diving its way down to the south of the uk. that's allowed an area of low pressure to develop and it's this area of low pressure that we're going to keep in the week ahead. so most of us will see some rain, we'll also see quite a big drop in temperature, both by day and by night. in the short term, the focus is on the thunderstorms. we've a met office warning across parts of southern england, including the midlands and south wales through sunday. thunderstorms initially developing across parts of east anglia, south—east england, will work their way gradually westwards through the day into parts of the midlands, maybe into wales,
