00:00Hello, it has been a hot and humid end to the working week in places and overnight Friday

00:06and into the start of the weekend there's the risk of some very impactful weather.

00:10Initially it's the likelihood of thunderstorms we're watching across northeast England later

00:15on Friday and by Friday evening they're moving into the North Sea.

00:19But then all eyes on developments across northern France as very lively thunderstorms start

00:25to move up through the channel and arrive into the southeast of England bringing lightning, hail, gusty winds

00:31but of greatest concern very heavy rainfall. For much of the UK it's a muggy night, an uncomfortable

00:36warm for sleeping, temperatures staying up at 18 or 19 Celsius in places but it's also going to be

00:41a noisy night for sleeping with these thunderstorms moving up from northern France. Although there's

00:47likely to be some hail and lightning in places that will be hit and miss as is always the case

00:52with thunderstorms not everyone will experience hail and lightning. But of greatest concern as I

00:58mentioned within this area, highly populated part of the UK, there's the risk of 100 millimetres of

01:04rainfall falling in less than three hours. To put that into context, that's a month or even two months

01:10worth of rain falling in less than three hours. In a part of the country where we do need the rain but

01:15of course we've got dry ground and all that rainfall coming into such a short space of time could cause

01:22some real issues overnight and the start of the weekend. A more broad yellow warning across much

01:26of England there for heavy showers and spells of more persistent outbreaks of heavy rain moving north

01:35as the morning progresses and into the afternoon that starts to appear into southern and eastern

01:40Scotland. Further west there'll still be some showers, western Scotland, northern Ireland, Wales in the

01:45southwest, some heavy downpours but these will be interspersed by some drier conditions, a lot of cloud cover

01:51where we do see the sunshine, temperatures still potentially up to the mid-20s but temperatures held back of

01:56course where we've got the heavy rain coming through through the day. The system that brings the heavy rain and

02:00thunderstorms move in moves into eastern and northeastern Scotland overnight. Another system, an area of low

02:06pressure, wraps into parts of southwest England to bring further lively weather for Sunday. So Saturday night

02:13we've got the spells of heavy rain moving through parts of Scotland particularly towards the east. That accumulating

02:19again and potentially bringing some localised flooding by early Sunday to eastern Scotland.

02:25Meanwhile it's drier for a time across England and Wales but the next system on Saturday night brings strong winds to some

02:32places but also more widely heavy showers especially towards the far southwest. So Cornwall could see some impacts from this

02:40wet weather as we go through Sunday. Northern Ireland a gap in between weather systems, plenty of sunshine, likewise for northern

02:46England albeit relatively cloudy skies and then East Anglia dry starts to Sunday but we've got showers moving in here and by the end of

02:54Sunday widely showers across the UK, slow moving, heavy downpours and again some impacts with surface water flooding and traffic

03:03traffic disruption and so on. So plenty to go on this weekend and you can keep up to date

03:09with all the latest updates on our YouTube channel. Bye bye.
