0:00:02 > 0:00:05Hello. Mixed weather for the weekend - some sunshine, some rain -
0:00:05 > 0:00:06but the thing we probably noticed the most,
0:00:06 > 0:00:08the temperatures edging up.
0:00:08 > 0:00:11And in fact with 15.3 Celsius in London on Saturday,
0:00:11 > 0:00:14it was the warmest day of the year so far,
0:00:14 > 0:00:15but it could well be that by next weekend,
0:00:15 > 0:00:18temperatures are going in the opposite direction once again.
0:00:18 > 0:00:21As this forecast looks further ahead than the others,
0:00:21 > 0:00:22we'll get to that in just a moment.
0:00:22 > 0:00:25Now, the reason things have been turning a bit milder,
0:00:25 > 0:00:27this area of low pressure to the south-west of us
0:00:27 > 0:00:30pushing in some mild air northwards across the UK.
0:00:30 > 0:00:33But it did come with some rain and some showers,
0:00:33 > 0:00:35and it will still do that during Monday,
0:00:35 > 0:00:37as it's still close by England and Wales.
0:00:37 > 0:00:41So bands of wet weather circulating around that area of low pressure.
0:00:41 > 0:00:42A few brighter spells.
0:00:42 > 0:00:45The rain just fringing into eastern parts of Northern Ireland,
0:00:45 > 0:00:46the far south of Scotland.
0:00:46 > 0:00:49North of that, mainly cloudy, mainly dry.
0:00:49 > 0:00:51And temperatures have come down a bit compared with the weekend,
0:00:51 > 0:00:53so more of us seeing temperatures
0:00:53 > 0:00:56topping out in single figures once again.
0:00:56 > 0:00:57Now, finally, going into Tuesday,
0:00:57 > 0:00:59that area of low pressure pulls away,
0:00:59 > 0:01:01get a little bump in the isobars -
0:01:01 > 0:01:04that means a ridge of high pressure coming in for Tuesday,
0:01:04 > 0:01:06settling things down. Slow start, mind you,
0:01:06 > 0:01:09a good deal of cloud around particularly eastern parts,
0:01:09 > 0:01:12and still a bit of rain for a time, East Anglia, south-east England.
0:01:12 > 0:01:13Brightening up into the afternoon,
0:01:13 > 0:01:15more especially across western parts,
0:01:15 > 0:01:17and temperatures have edged up a little bit
0:01:17 > 0:01:19so some spots in Scotland, for example,
0:01:19 > 0:01:21getting back into double figures.
0:01:21 > 0:01:22Under clearing skies, though,
0:01:22 > 0:01:25chilly enough for a touch of frost on Tuesday night,
0:01:25 > 0:01:28then for Wednesday, our ridge of high pressure is just about gone
0:01:28 > 0:01:31as low pressure parks itself to the south-west of us
0:01:31 > 0:01:33for the rest of the week.
0:01:33 > 0:01:35It will have a limited attempt during Wednesday
0:01:35 > 0:01:38to bring in a band of wet weather towards the south-west -
0:01:38 > 0:01:41more cloud in the west. Notice the wind arrows, though -
0:01:41 > 0:01:43the most noticeable thing about Wednesday's weather
0:01:43 > 0:01:45will be a strengthening southerly wind.
0:01:45 > 0:01:48More widely, temperatures in double figures, mind you,
0:01:48 > 0:01:50but then again, the wind will be picking up.
0:01:50 > 0:01:52Our area of low pressure to the south-west of us
0:01:52 > 0:01:55will then try to feed a band of cloud and rain
0:01:55 > 0:01:57further east during Thursday. Uncertain progress.
0:01:57 > 0:02:00Here it is - may not look exactly like this by Thursday,
0:02:00 > 0:02:02but the best chance for still some sunny spells
0:02:02 > 0:02:04will be across eastern parts.
0:02:04 > 0:02:06The wind more of a south-easterly
0:02:06 > 0:02:08and it does mean something a little bit cooler coming in
0:02:08 > 0:02:10towards the North Sea coast.
0:02:10 > 0:02:13And then on Friday the low pressure is still to the west of us,
0:02:13 > 0:02:16is still trying to feed in cloud and outbreaks of rain north-eastwards
0:02:16 > 0:02:18across the UK. To the south of that, brightening up a bit,
0:02:18 > 0:02:21with a few showers, though temperatures here
0:02:21 > 0:02:23edging up towards 12 or maybe even 13 degrees.
0:02:23 > 0:02:26Now, then. Why is that area of low pressure
0:02:26 > 0:02:28parking itself to the west of us,
0:02:28 > 0:02:31not just coming right on through with its wet weather?
0:02:31 > 0:02:33Well, we'll look at the big picture, and it could well be
0:02:33 > 0:02:35that it's reaching a block in the atmosphere.
0:02:35 > 0:02:38The block will be an area of high pressure in Scandinavia.
0:02:38 > 0:02:41The flow of air around that, some colder air coming back in,
0:02:41 > 0:02:45but there's a lot of uncertainty about how cold the air will be
0:02:45 > 0:02:47as it starts to filter through during the course of next weekend.
0:02:47 > 0:02:51If comes right from the east it will be particularly chilly,
0:02:51 > 0:02:54but this latest image is less chilly
0:02:54 > 0:02:56but still colder than what we have at the moment.
0:02:56 > 0:02:58So there's still a lot to play for
0:02:58 > 0:03:00in the detail of next weekend's weather
0:03:00 > 0:03:02in just how cold it may get
0:03:02 > 0:03:05and how widely that colder air will move across the UK.
0:03:05 > 0:03:07But the indications are next weekend,
0:03:07 > 0:03:09or into the start of the following week,
0:03:09 > 0:03:12something colder coming back from the east.
0:03:12 > 0:03:15A chilly wind developing, so wind chill may be more of an issue,
0:03:15 > 0:03:17and a risk of wintry showers - not a guarantee,
0:03:17 > 0:03:21but more towards the north-east of the UK, maybe north-east England
0:03:21 > 0:03:23and into eastern Scotland, especially over higher ground.
0:03:23 > 0:03:25Still loads of play for in the detail
0:03:25 > 0:03:28so we will keep monitoring this as we go through the week.
