00:00Hi there.

00:01Love it or hate it, it's going to be a very warm night across the UK.

00:05High humidities, and despite the clear skies we're expecting, temperatures won't drop

00:10much below the mid to high teens.

00:12We've seen the heat extend across much of the UK during Friday as high pressure drifts

00:16slowly to the east, but that does introduce some instability from the west, always a chance

00:21of a few showers continuing into the hours of darkness, but for the vast majority it's

00:27going to stay dry, we're going to see extensive clear spells, but we're also going to see

00:31those high temperatures remaining.

00:34So an uncomfortable night for sleeping for many, and a muggy start to the weekend.

00:40Temperatures in some spots no lower than 20, 21 Celsius.

00:44Even in the cooler areas, temperatures tending to stay in the teens.

00:48Now we go into the start of the weekend with that warm air in place and it's only going

00:52to get warmer throughout the day.

00:55With that very strong June sunshine, it is the summer solstice, so the sun doesn't get

00:58any stronger than this.

00:59Very high UV levels, high pollen levels as well, grass pollen at the moment.

01:03The temperatures will be highest towards the east.

01:05Lower temperatures in the west compared with Friday, but still high humidity, so it's going

01:09to feel oppressive in many places, and all this chance of some showers developing as

01:14the day progresses, particularly towards the west.

01:17Temperatures peaking at 31 to 33 or 34 Celsius somewhere between London, the Midlands and North-East

01:24England.

01:25And then with that heat in place, and we've got the winds changing direction, fresher

01:31air moving in from the west, we're going to see the risk of thunderstorms as the day comes

01:36to an end.

01:37And the greatest risk area is this zone across parts of southern Scotland, North England,

01:43North Midlands and North Wales.

01:44In fact, it's across Northern England, North Midlands and North-East Wales where there is

01:48a yellow thunderstorm warning at the time of recording.

01:52And that's where there is the greatest risk of impacts from these thunderstorms that will

01:57be hit and miss.

01:58Obviously, not everywhere in this warning area will catch a thunderstorm, but that's where

02:02the greatest risk of impacts from large hail, 2 to 4 centimetres, frequent lightning, gusty

02:07winds and some very heavy rain will be later Saturday and going into the early hours of

02:14Sunday.

02:15That doesn't rule out thunderstorms elsewhere.

02:18There could always be thunderstorms further south and further west.

02:21In fact, there's another area of heavy downpours that is likely to affect parts of western

02:25Scotland overnight.

02:27Either way, it's going to be a warm night once again.

02:30Temperatures widely in the mid-teens, but particularly towards the east and southeast.

02:34Some places seeing temperatures stay at around 20 Celsius.

02:38The liveliest thunderstorms then move through during Sunday morning.

02:41A bright start for many, actually.

02:43Some decent sunshine once again towards the southeast.

02:46And there will be some sunny spells coming through elsewhere, but a lot of clouds starting

02:49to appear from the west.

02:51Further showers.

02:52A very showery day indeed for Scotland, Northern Ireland, Northern England and parts of Wales.

02:57Dryer towards the southeast.

02:58That really sets the scene for next week.

03:00It's going to be changeable with the Atlantic westerlies having returned.

03:03There will be frequent showers, particularly towards the west and northwest.

03:07Dryer towards the south and southeast, but fresher for all of us.
