hello again. tuesday was the hottest day of the year so far. a title that will last until, well, later today when temperatures are expected to get a little higher still. most of us had skies like this, then, plenty of sunshine around and it was warm widely. 26.1 celsius was the highest temperature — that was in cardiff where we have the heat as far north as northern scotland at kinloss at 25 celsius. here, just 11 celsius. here we had low clouds and fog. there is another batch waiting to move across the north sea over the next few hours. meanwhile, over in france, we have some thunderstorms beginning to spread their way northwards. now, those thunderstorms coming from a cloud called altocumulus castellanus. you quite often don�*t get much rain from it, what falls can be big blobs, but you can get pretty dazzling lightning displays and lots of thunder. you might see some of that
