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 much
00:10below 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
01:24North East England.
01:25And then with that heat in place and we've got the winds changing direction, fresher air
01:31moving 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 Sunday.
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 Scotland
02:26overnight.
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 and there will be some sunny spells
02:47coming through elsewhere, but a lot of clouds starting to 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'll be frequent showers, particularly towards the west and northwest.
03:07Dryer towards the south and southeast, but fresher for all of us.
03:10That would be facilitated.
03:11I hope you guys would like to be feeling the only EPA.
03:13That would perhaps be in
03:34a shorter PI Cup.
