00:00Hello, Thursday was hot, Friday for most of us likely to be a little bit hotter and certainly
00:06a very warm and humid night Thursday night and into Friday. Now it's not completely fine out
00:12there, but a cloud across Northern Ireland may produce the odd rumble of thunder as it drifts
00:16into parts of southern Scotland and central Scotland through the night and also down to
00:20the southwest. The possibility you could get woken up by a rumble of thunder or a flash of
00:24lightning. But for the vast majority, it's dry, long clear spells and temperatures holding up a
00:30very warm and humid feel, particularly so across Wales and southwest England, where some urban areas
00:36may not drop below 19 degrees Celsius. So a warm and sticky night and as I said, a hot day to come
00:43on Friday. Now there will be more cloud around on Friday, so the sunshine certainly hazier for England
00:48and Wales and the clouds thick enough for one or two, isolated but potentially heavy thundery showers
00:54across southwest England and south Wales early on. And then the chance of the afternoon could
00:58generate some thunderstorms, maybe parts of northern England a greatest chance over northern Scotland.
01:04Again, very hit and miss, but where they do occur, again, could generate some lightning and some
01:09rumbles of thunder. For most places though, it is just a hot day of hazy sunshine, a warmer day for
01:16Northern Ireland and Scotland compared to Thursday. Temperatures in northern Scotland getting into the
01:21mid, maybe even high 20s in places and over 30 Celsius across parts of East Wales, the Midlands
01:26and some parts of eastern England. We could get up to maybe 32, always a little bit cooler around some
01:33coasts, a little bit more comfortable here perhaps. Now through Friday evening, not a great deal of
01:38change, maybe still the odd thunderstorm rumbling on over northern Scotland, but otherwise largely dry,
01:42perhaps turning a little mistier around the coasts in the southwest. The humidity remains high and more
01:48widely across the south. Temperatures staying in the high teens, a greater chance as we head into
01:53Saturday that we're still above 20 Celsius in a few places that would make it a tropical night. So again,
02:00a difficult night for sleeping. Now Saturday we'll probably see the peak of the temperatures,
02:05but also an increased chance of thunderstorms. Parts of western England, Wales especially, and later in the
02:12day, North Wales, northern England, maybe southern Scotland, the Midlands, susceptible to some
02:16torrential downpours. They'll still be hit and miss. Again, not everywhere catching them, but these
02:21beasts on Saturday do need watching, generating a lot of lightning and the possibility of local
02:27flooding. So that's something we're keeping an eye on. Again, many places won't see them and just stay
02:31dry with plenty of hot, hazy sunshine. The heat peaking in the east at least, 30, 33, maybe even 34.
02:39Temperatures not as high in the west as we start to see a change, but it won't feel any more comfortable
02:44here. It'll still be pretty humid during Saturday, but the numbers on the thermometer not quite as
02:50high. And we are going to see those temperatures dipping down further as we head into Sunday. But
02:55still a very warm start across eastern areas. Now the heat building through high pressure sitting to
03:00the east and southerly winds picking up. But there is this low pressure further west. That's what's
03:06likely to destabilise things and potentially bring those damaging thunderstorms in places on Saturday.
03:12But as that low drifts northwards by Sunday, the winds are now coming in from the west or the
03:16southwest. And that's when it will start to turn fresher. If we put the temperature profile on,
03:21you can see that heat building through Friday night and Saturday, a very warm night. And then that heat
03:26continuing into Saturday before it starts to get shunted away. The high pressure drifts away,
03:31the low takes over, and those westerly winds will bring cooler conditions as we head into next week.
