there will be some mist and fog forming, maybe northern wales, merseyside, lancashire. and mild, if not quite warm, 15, 16, 17 degrees around dawn. and the temperatures will quickly skyrocket as we go through the morning and into the afternoon. now, it's going to be sunshine pretty much all around, although across some far northwestern parts of the country, it could be a little hazy and cloudy. and much cooler in stornoway, 18 degrees, but the mid—20s for the lowlands of scotland, 27 for yorkshire, 30 possible in the midlands. and if we do get 30, which we are very likely to get 30, it will be the hottest day since the 23rd ofjuly, after a relatively cool august, because the temperatures never really got that high during august — a little unusual. so this is what it looks like on wednesday, the weather map. you can see a low pressure approaching us, weather fronts here too. these are showers and thunderstorms reaching southwestern parts of england and also wales, some showers getting into northern ireland too, but the rest of the country is still basking in that summer sunshine — temperatures just shy of 30 degrees, i think, on wednesday.
