00:00Hi there. The heat and humidity continues to rise during the rest of the day and that could spark some very severe weather overnight.
00:08The Met Office have issued an amber warning for thunderstorms across parts of eastern England.
00:13But ahead of those thunderstorms, actually long spells of sunshine for much of England and Wales and for Scotland and Northern Ireland also some bright spells,
00:21although showers will occur on and off here and there'll be cloudier skies in general across much of Scotland and Northern Ireland.
00:28The cloud then thickens across Wales and southwest England with heavy rain moving in here by the evening rush hour.
00:35But before the thunderstorms arrive in the east and southeast, it is going to be very warm, if not hot.
00:40Temperature is peaking at 29 Celsius.
00:43Here's the system that's likely to bring some lively weather overnight.
00:46And it's these frontal systems that'll bring some heavy rain and some thunderstorms to many parts of the UK.
00:53But within these frontal systems, within this plume of heat and humidity emanating from Northern France, that's likely to destabilise.
01:03And that's where the most severe thunderstorms are likely to occur across parts of the east and southeast of England.
01:11So initially during the evening, it's dry towards the southeast, but we'll be watching developments over northern France very closely,
01:18because that's where these thunderstorms are likely to develop and drift northeastwards.
01:23As always, there's an element of uncertainty in terms of the exact track of these systems.
01:28We won't know the finer details precisely until it starts to take place.
01:33But the signals are that it's across east Anglia and the far southeast of England, so Kent, Essex, Suffolk, Norfolk,
01:40where we're likely to see the greatest risk of impacts from the torrential rain, large hail, one, two centimetres in diameter,
01:51frequent lightning and gusty winds, 50 mile per hour wind gusts, perhaps more with some of the most lively thunderstorms.
01:59And so all of those elements could cause impacts across parts of east Anglia and the southeast in particular during the hours of darkness.
02:07But of course, the amber thunderstorm warning reflects the fact that it's a risk of these impacts occurring,
02:15not a guarantee, because we'll have to keep an eye on developments across northern France
02:19and see exactly where they're going to end up as they drift northwards.
02:23And even if you're not in the amber zone, there are yellow warnings in force for thunderstorms across many other parts of the UK,
02:30areas of heavy rain and thundery showers drifting north across parts of western England, Wales,
02:35and then into Scotland and Northern Ireland by the end of the night.
02:38Meanwhile, later in the night, anything that does develop across the southeastern quarter
02:42tends to drift into the North Sea as an area of heavy rain.
02:46And it's going to be a muggy night wherever you are, whether you've got the thundery rain or any clear spells that happen to continue.
02:53Temperatures not drifting much below 16 or 17 Celsius.
02:58We start off Saturday with areas of heavy rain, thundery showers and some very wet weather in places.
03:04Not everywhere will be affected, but you can see how messy it becomes during Saturday morning
03:08with an area of low pressure in place across the UK.
03:11Persistent rain for Scotland and Northern Ireland, some thundery showers for northern and central England,
03:15but brighter skies developing across the south and southeast.
03:19By the end of the afternoon, it's largely dry and sunny towards East Anglia and the southeast,
03:25with temperatures still reaching the mid-20s in places.
03:27We've still got relatively warm and humid air here.
03:30Then, later Saturday, any rain and thundery downpours tend to slowly ease,
03:36but we do still have a wet end to the day across parts of Scotland as well as Northern England.
03:41Drier towards the south with clear spells,
03:43and that's a sign of a change on the way for later in the weekend.
03:47We've got higher pressure starting to build towards the south,
03:51and so a fine day in the south on Sunday,
03:53and the more settled weather develops more widely across the UK as we go into next week.
