0:00:03 > 0:00:06Hello, thanks for tuning in to the weather for the week ahead.
0:00:06 > 0:00:09Over the next three or four days, there isn't going to be much
0:00:09 > 0:00:10change on the weather front.
0:00:10 > 0:00:14So this pattern where we've got the colder weather across Scotland
0:00:14 > 0:00:18and the milder, cloudy weather in the south isn't really going to shift.
0:00:18 > 0:00:20This is the satellite picture from Thursday.
0:00:20 > 0:00:23This is the forecast first thing in the morning on Friday.
0:00:23 > 0:00:25Look how mild it is first thing, 9 degrees.
0:00:25 > 0:00:28But we've got weather cold enough for some wintry showers across Scotland.
0:00:28 > 0:00:31That's how it's going to stay through the course of Friday.
0:00:31 > 0:00:34No real difference, milder in the south, colder in the north.
0:00:34 > 0:00:36But there will be some sunshine around.
0:00:36 > 0:00:39So, actually, the weather for many of us isn't that bad at all.
0:00:39 > 0:00:42Let's have a look at a snapshot of Friday afternoon.
0:00:42 > 0:00:43This is three o'clock.
0:00:43 > 0:00:45You can see it is chilly in Inverness, 3 degrees.
0:00:45 > 0:00:47But we've got some sunshine around.
0:00:47 > 0:00:51The breeze is quite strong, so it will feel fairly chilly.
0:00:51 > 0:00:557 degrees there, Belfast, with one or two showers.
0:00:55 > 0:00:56Look at this swathe of the country all
0:00:56 > 0:00:59the way from Yorkshire across Wales and down into the
0:00:59 > 0:01:02Midlands, East Anglia, actually not a bad day at all.
0:01:02 > 0:01:04But the south of the country, here,
0:01:04 > 0:01:07the southern portion is cloudier with some spots of rain.
0:01:07 > 0:01:10Here temperatures will be around 9 or 10 degrees.
0:01:10 > 0:01:13Not an awful lot of difference from the overnight temperature.
0:01:13 > 0:01:17On Friday night into Saturday, there will be a bit of a change on the way.
0:01:17 > 0:01:20We're still going to be talking about these dividing lines
0:01:20 > 0:01:22between the milder air to the south
0:01:22 > 0:01:25and the colder air to the north.
0:01:25 > 0:01:26This weather front here,
0:01:26 > 0:01:29what it is going to do, through the course of Saturday morning,
0:01:29 > 0:01:34is actually slide along this zone of big temperature difference.
0:01:34 > 0:01:37What that means is where the rain engages that colder air
0:01:37 > 0:01:39in the north, it will properly turn to snow
0:01:39 > 0:01:42across parts of Cumbria Tom maybe the Pennines,
0:01:42 > 0:01:45it's really tricky to say exactly how much we're going to get.
0:01:45 > 0:01:48But I think the basic message is further south across Wales
0:01:48 > 0:01:51and into the Peak District, that will be rain.
0:01:51 > 0:01:54Across the hills into the Pennines and Cumbria it will probably be snow.
0:01:54 > 0:01:57Only transient, we're only talking about a few hours worth of snow.
0:01:57 > 0:01:59Either side of that, the weather will be better.
0:01:59 > 0:02:02So mild again in the south, 13 degrees there in London,
0:02:02 > 0:02:06but colder for northern Scotland 3 or 4 degrees.
0:02:06 > 0:02:10On Sunday, again that low pressure still there.
0:02:10 > 0:02:12It is quite a slow-moving one really.
0:02:12 > 0:02:14Quite often low-pressures zip across the UK,
0:02:14 > 0:02:16but this one will be stuck just towards the west
0:02:16 > 0:02:20and south-west of us and this weak weather front will be slicing
0:02:20 > 0:02:22the country around about the Midlands.
0:02:22 > 0:02:25So that means the south coast will be mild
0:02:25 > 0:02:27again for December, around 12 degrees.
0:02:27 > 0:02:30Just a hint as we head into Monday, that this low pressure will
0:02:30 > 0:02:33sort of take charge of the weather a little bit more across the UK.
0:02:33 > 0:02:36That means stronger winds, these weather fronts making a bit more
0:02:36 > 0:02:39progress to the north, so that means that the really chilly air
0:02:39 > 0:02:41that we will have seen across Scotland will actually
0:02:41 > 0:02:43move away further north.
0:02:43 > 0:02:45So that means temperatures there in the north of Scotland
0:02:45 > 0:02:47around 8 degrees or so.
0:02:47 > 0:02:49Rather than 3 or 4.
0:02:49 > 0:02:51A similar picture on Tuesday
0:02:51 > 0:02:53and that low-pressure is still out there, it's sitting there
0:02:53 > 0:02:55not really doing an awful lot.
0:02:55 > 0:02:58For the middle part of the week, so that's midweek next week, that
0:02:58 > 0:03:03low is still pumping in moisture and mild air from the southern climes.
0:03:03 > 0:03:06It's because of the orientation of the jet stream.
0:03:06 > 0:03:08Whenever we get this southerly component of the jet stream,
0:03:08 > 0:03:13the air comes in from the south, so that's why we got that milder air.
0:03:13 > 0:03:15But by the time we get to the latter part of the week,
0:03:15 > 0:03:18say in around 10 day's time, that low-pressure
0:03:18 > 0:03:21comes in more from the west and there's a chance that slightly
0:03:21 > 0:03:24colder air will be digging in behind these areas of low pressure.
0:03:24 > 0:03:26But before that happens, it's still uncertain,
0:03:26 > 0:03:29we could see a spell of slightly quieter weather, perhaps
0:03:29 > 0:03:31high-pressure, but it's still a long way off.
0:03:36 > 0:03:37Forensics found what was left.
0:03:39 > 0:03:41What do we do with something like this?
0:03:45 > 0:03:46Find our man.
0:03:47 > 0:03:49Sorry, mate, who are you again?
0:03:51 > 0:03:52Police.
