00:00Hi there.
00:01It is a remarkably hot start to May for many, but not for all, a change is already taking
00:07place across Scotland and Northern Ireland as a cold front sinks south.
00:10This is its position early afternoon, just crossing the border between Scotland and England.
00:15And along that cold front we've got areas of cloud and some showers, even the odd thunderstorm
00:19into the afternoon.
00:21Showers also arriving into the north-west of Scotland, patchy cloud here and a much fresher
00:25feel with winds coming in from the Atlantic.
00:28But further south we keep the heat and that heat has been building day by day each day
00:32this week, with the heat enough to set off odd shower or thunderstorm through central parts.
00:38But for most it's going to stay sunny and it's going to be a degree or two warmer compared
00:44with Wednesday.
00:46So widely 26 to 28 Celsius across England and Wales, up into the Vale of York, north-west
00:52England, Cheshire for example.
00:54But in some spots the potential for 29 Celsius, a remarkably hot start to May like I say.
01:01But further north you can see that temperature contrast, mid-teens more likely across much
01:05of Scotland and Northern Ireland as the cooler air sinks south.
01:08The temperatures will be falling through the afternoon across parts of northern England
01:11as that cold front moves through.
01:13The cold front tends to fizzle away but we keep that temperature contrast overnight.
01:17And it's a warm night across southern parts of the country, chance of a few showers, even
01:21a thunderstorm rumbling through the hours of darkness for central parts.
01:25Thicker cloud arriving into the south and south-west by the end of the night as well,
01:28a few spots of rain.
01:29But also a few showers into the north-west with a north-westerly breeze.
01:34And big temperature contrasts remain overnight with lows down to the low single figures across
01:40parts of northern England, Northern Ireland and Scotland in sheltered spots.
01:44A grass frost possible further south, mid-teens in some places.
01:49So a warm night, an uncomfortable night for sleeping for southern parts of Wales and England.
01:54We start off Friday with that warmth across the south and south-east.
01:58Plenty of sunshine after one or two showers first thing.
02:01And it's another sunny day for many parts of England and Wales.
02:04I think a bit more cloud there for Northern Ireland and Scotland.
02:06But even here, brighter skies return for the afternoon, showers arriving into the Northern
02:11Isles.
02:12But otherwise, for most, it's a dry day.
02:14Again, plenty of sunshine.
02:16Not quite as hot in the south, but still temperatures up to 26 or 27 in some spots of
02:21the far south and south-east.
02:22Otherwise, temperatures are significantly lower across the board and mid-teens more likely
02:27across many parts of northern and western UK.
02:31But still the potential for the odd shower or thunderstorms to develop, this time southern
02:35counties of England into the afternoon.
02:39Then later Friday, the cooler air that we've got across the northern two-thirds of the UK
02:44eventually reaches the south.
02:46And for the long weekend, well, we've got a change in feel, but not necessarily a significant
02:51change in the type of weather.
02:53Effectively, high pressure is still with us.
02:56And that high pressure is going to maintain fine, settled weather for many places.
03:01But there'll be more cloud, there'll be a few showers coming into the east at times, and
03:06there'll be a significant drop in temperatures.
03:09In fact, below average temperatures are possible in the east by Sunday because of this air coming
03:13down from the North Sea.
03:16In the sunshine, towards the west and south-west, still feeling pleasant enough.
03:20But like I say, temperatures significantly lower than recent days.
03:23The dry and mostly bright weather continues into next week.
03:27High pressure rebuilds across the UK, so no sign of significant rain for some time.
