0:00:02 > 0:00:05Hello there. Our weather is stuck in something of a rut at the moment.

0:00:05 > 0:00:06The winds are very light,

0:00:06 > 0:00:08there's nothing to push things along,

0:00:08 > 0:00:10nothing to change things very quickly,

0:00:10 > 0:00:13and a lot of that is down to the jet stream.

0:00:13 > 0:00:15Instead of steering weather systems

0:00:15 > 0:00:17across the Atlantic, towards our shores,

0:00:17 > 0:00:20the jet is diving down to the south.

0:00:20 > 0:00:21All the strength, all the energy

0:00:21 > 0:00:23in the jet is going down to the south,

0:00:23 > 0:00:25and that means areas of low pressure

0:00:25 > 0:00:27will spin around close to Iberia.

0:00:27 > 0:00:28What we're left with is a very

0:00:28 > 0:00:30weak pressure pattern, really -

0:00:30 > 0:00:31not many isobars, the winds will be light,

0:00:31 > 0:00:33low pressure vaguely in charge

0:00:33 > 0:00:35to the north-west, so that means here,

0:00:35 > 0:00:36we'll see some rain at times.

0:00:36 > 0:00:38Not all the time, and it will be fairly cool.

0:00:38 > 0:00:40High-pressure vaguely in charge

0:00:40 > 0:00:41down to the south-east,

0:00:41 > 0:00:44so that means it will be largely dry,

0:00:44 > 0:00:46pleasantly warm in any sunshine

0:00:46 > 0:00:47and I suspect some parts

0:00:47 > 0:00:50of the south-east may stay completely dry

0:00:50 > 0:00:52as we go on through the coming days.

0:00:52 > 0:00:53On Friday, there will be a fair amount

0:00:53 > 0:00:55of sunshine for East Anglia and the south-east.

0:00:55 > 0:00:56Bit more cloud for Wales

0:00:56 > 0:00:58and northern England, the odd shower,

0:00:58 > 0:01:00some showers for Northern Ireland.

0:01:00 > 0:01:02Again, some rain here on Friday

0:01:02 > 0:01:04and some of those showers into Scotland.

0:01:04 > 0:01:06Now, as we go on through Friday night,

0:01:06 > 0:01:07while showery rain continues

0:01:07 > 0:01:09across Northern Ireland for a time,

0:01:09 > 0:01:11it should eventually dry up a little bit here.

0:01:11 > 0:01:12Showery rain continues across Scotland.

0:01:12 > 0:01:14Further south, largely dry -

0:01:14 > 0:01:16the odd fog patch and maybe beginning

0:01:16 > 0:01:18to turn a bit humid down towards the south-east.

0:01:18 > 0:01:20Now, one subtle change on Saturday -

0:01:20 > 0:01:22this frontal system sinking its way

0:01:22 > 0:01:23a little bit further south.

0:01:23 > 0:01:26That will introduce perhaps a little more cloud

0:01:26 > 0:01:28for England and Wales, and there may just be

0:01:28 > 0:01:29the odd isolated shower here,

0:01:29 > 0:01:31but the vast majority here will stay dry.

0:01:31 > 0:01:32Still some showers for

0:01:32 > 0:01:34Northern Ireland and Scotland,

0:01:34 > 0:01:36maybe not quite as many showers by this stage,

0:01:36 > 0:01:38but some of them could still be on the heavy side.

0:01:38 > 0:01:40Quite a range of temperatures -

0:01:40 > 0:01:4117 degrees there in Glasgow,

0:01:41 > 0:01:43but 20 in Cardiff,

0:01:43 > 0:01:45and we could get to 25 in London.

0:01:45 > 0:01:47Now, Sunday will actually bring

0:01:47 > 0:01:48a fair amount of dry weather

0:01:48 > 0:01:50right across the country.

0:01:50 > 0:01:52Still some showers in the far north-west.

0:01:52 > 0:01:54Perhaps an isolated heavy shower further south,

0:01:54 > 0:01:56just a small chance of that, I suspect,

0:01:56 > 0:01:5817 to 24 degrees.

0:01:58 > 0:02:00But this if we look at the pressure pattern

0:02:00 > 0:02:02as we head on into Monday,

0:02:02 > 0:02:04a bank holiday for many places, of course,

0:02:04 > 0:02:06you can see things becoming a little more mobile.

0:02:06 > 0:02:08The white lines squashing together

0:02:08 > 0:02:10a bit more, that means there will be more

0:02:10 > 0:02:12of a breeze and this band of rain,

0:02:12 > 0:02:14heavy rain in the north-west,

0:02:14 > 0:02:16sinking its way southwards and eastwards,

0:02:16 > 0:02:18but weakening as it goes and, yes, you guessed it -

0:02:18 > 0:02:19parts of the south-east

0:02:19 > 0:02:21will stay completely dry during Monday.

0:02:21 > 0:02:23Now, through Monday night, our weather front

0:02:23 > 0:02:25sinks southwards and eastwards,

0:02:25 > 0:02:27but it's weakening all the while,

0:02:27 > 0:02:29so not much rain into the south-east.

0:02:29 > 0:02:32Maybe just some patches on Tuesday morning.

0:02:32 > 0:02:33Then a bit of a drier interlude,

0:02:33 > 0:02:35but we have a westerly wind -

0:02:35 > 0:02:37never a warm wind direction, so temperatures

0:02:37 > 0:02:4014 to 21 degrees at best.

0:02:40 > 0:02:42Now, as we get deeper into the week,

0:02:42 > 0:02:44our jet stream, instead of diving

0:02:44 > 0:02:45way down to the south,

0:02:45 > 0:02:47is making more of a beeline

0:02:47 > 0:02:48for the British Isles.

0:02:48 > 0:02:49That means weather systems will

0:02:49 > 0:02:51move in our direction and,

0:02:51 > 0:02:52on the face of it, it makes things

0:02:52 > 0:02:54look a little bit more changeable.

0:02:54 > 0:02:56However, low pressure is likely

0:02:56 > 0:02:57to sit to the north.

0:02:57 > 0:02:59Generally, we'll have a westerly wind,

0:02:59 > 0:03:00and what that means is, once again,

0:03:00 > 0:03:02the wettest of the weather will be

0:03:02 > 0:03:03up towards the north-west.

0:03:03 > 0:03:05Bands of rain or showers moving in,

0:03:05 > 0:03:08then as they move southwards and eastwards,

0:03:08 > 0:03:09remember, we move away from

0:03:09 > 0:03:10that area of low pressure,

0:03:10 > 0:03:12the rain will tend to weaken

0:03:12 > 0:03:13and we also have some shelter

0:03:13 > 0:03:15from that westerly wind, so eastern areas

0:03:15 > 0:03:17will see a lot of dry weather.

0:03:17 > 0:03:19Later next week, then, the pattern continues -

0:03:19 > 0:03:21the wettest weather will be in the north-west,

0:03:21 > 0:03:24it'll always stayed drier towards the south-east

0:03:24 > 0:03:26and no heatwave on the cards.

0:03:26 > 0:03:27Generally quite cool,

0:03:27 > 0:03:30so not too much changing over the next few days.
