Hello. It's already turned cold, but this cold snap has another gear. | 0:00:03 | 0:00:06 | |
It is going to get even colder as we go into the weekend. | 0:00:06 | 0:00:09 | |
Potentially, turner milder at some point next week, | 0:00:09 | 0:00:12 | |
but there is a lot of uncertainty about that, as we'll see in a moment. | 0:00:12 | 0:00:16 | |
For the time being, it is cold and we have low pressure sitting over us, | 0:00:16 | 0:00:19 | |
bringing moisture. That combination providing some wintry weather. | 0:00:19 | 0:00:24 | |
Yes, some snow falling at the moment and it will continue, as that low | 0:00:24 | 0:00:27 | |
slowly heads out into the North Sea. A mixture of rain, sleet | 0:00:27 | 0:00:31 | |
and hill snow across parts of England and Wales, becoming confined through | 0:00:31 | 0:00:35 | |
the afternoon across the east. But still some sleet and snow likely, | 0:00:35 | 0:00:39 | |
chiefly over the hills, but potentially, even down to low levels. | 0:00:39 | 0:00:42 | |
Some wintry showers across northern Scotland, Northern Ireland. | 0:00:42 | 0:00:44 | |
For many, turning sunny, but it will be a cold, cold Thursday. | 0:00:44 | 0:00:48 | |
There is further potential for problems from this wintry weather. | 0:00:48 | 0:00:51 | |
A combination of ice, sleet and snow during Thursday and, indeed, | 0:00:51 | 0:00:55 | |
into Friday. Because that low slowly pulling away, still on Thursday | 0:00:55 | 0:00:59 | |
evening proving a mixture of rain, sleet and some hill snow | 0:00:59 | 0:01:02 | |
across eastern England. Then, further snow flurries coming in on this | 0:01:02 | 0:01:06 | |
weather front during the course of the early hours of Friday morning | 0:01:06 | 0:01:09 | |
could provide a covering on Friday morning's rush hour | 0:01:09 | 0:01:12 | |
and, again, potentially, quite icy. Friday, for many, is a sunny day, | 0:01:12 | 0:01:16 | |
but it will feel bitter in the winds and there is still a sprinkling | 0:01:16 | 0:01:19 | |
of snow showers to come. So, don't be surprised if you see the odd flake | 0:01:19 | 0:01:23 | |
over the next 48 hours or so. Then, for the next 48 hours, as I said | 0:01:23 | 0:01:27 | |
at the start, we see a change in gear. The isobars spread out, | 0:01:27 | 0:01:31 | |
as high pressure builds in. That means the winds fall lighter. | 0:01:31 | 0:01:35 | |
With light winds and high pressure and cold air, cold air is dense, | 0:01:35 | 0:01:40 | |
so it just sinks. With no winds to stir it up, | 0:01:40 | 0:01:45 | |
things just get colder at the surface and the nights, in particular, | 0:01:45 | 0:01:48 | |
this weekend will be bitter. Severe frosts likely. | 0:01:48 | 0:01:51 | |
This is not just going to be cold compared to this current, | 0:01:51 | 0:01:55 | |
pretty mild winter. This is going to be cold compared to ANY winter. | 0:01:55 | 0:01:58 | |
Now, there is a pay-off, in that most of us this weekend will see some | 0:01:58 | 0:02:02 | |
sparkling sunshine, but the mornings are going to be very cold. | 0:02:02 | 0:02:06 | |
Exceptionally cold. How low will we go? | 0:02:06 | 0:02:08 | |
Well, negative double figures is likely. -15C is possible, | 0:02:08 | 0:02:14 | |
where there is snow lying on the ground. | 0:02:14 | 0:02:17 | |
The coldest spell since, at least, March, 2013. | 0:02:17 | 0:02:20 | |
Into the new working week, high pressure still nearby. | 0:02:20 | 0:02:23 | |
Low pressure systems trying to come in but, as you can see, on Monday, | 0:02:23 | 0:02:27 | |
sort of, failing, really. The high is still dominant | 0:02:27 | 0:02:30 | |
as we go into next week. Yesterday, we were talking about just when | 0:02:30 | 0:02:34 | |
the milder air would arrive, pushing that high pressure system | 0:02:34 | 0:02:37 | |
out of the way. There is still a lot of doubt, but for the first half | 0:02:37 | 0:02:40 | |
of the week, it looks like the cold air, with the high pressure, | 0:02:40 | 0:02:43 | |
still in control. Now, this graph shows how we expect things to pan out | 0:02:43 | 0:02:48 | |
through the week ahead. Take this line. | 0:02:48 | 0:02:51 | |
This line is the computer models. Pretty much all of them suggesting | 0:02:51 | 0:02:55 | |
it is going to stay cold until at least Wednesday. | 0:02:55 | 0:02:57 | |
The problem comes after the middle of the week. Some computer models | 0:02:57 | 0:03:01 | |
will keep it cold. Others turn it much milder quicker. | 0:03:01 | 0:03:04 | |
And this spread, if you like, this change in the graph, this area | 0:03:04 | 0:03:10 | |
means there is a greater uncertainty, more uncertainty than usual, | 0:03:11 | 0:03:14 | |
about just how things will change. We do know it is going to be messy. | 0:03:14 | 0:03:18 | |
The start of the week looks cold. There is the risk of some snow. | 0:03:18 | 0:03:21 | |
It will eventually turn milder and wetter, but there is still a lot | 0:03:21 | 0:03:25 | |
of uncertainty, because those computers | 0:03:25 | 0:03:28 | |
are just not agreeing about exactly when that will happen. | 0:03:28 | 0:03:30 |
