0:00:02 > 0:00:04Hello. Weather is what the atmosphere throws at us
0:00:04 > 0:00:06minute by minute, day by day. Climate is the average
0:00:06 > 0:00:09of that over a long period of time. Interestingly,
0:00:09 > 0:00:12both were making news headlines on Thursday.
0:00:12 > 0:00:16Climate first. Several major weather organisations said that...
0:00:21 > 0:00:24Now, El Nino is a natural warming influence on the world's
0:00:24 > 0:00:26weather but it wasn't there in 2017, so even without it,
0:00:26 > 0:00:29the year comfortably took its place in the top-three
0:00:29 > 0:00:31hottest years on record around the world
0:00:31 > 0:00:34and that's why climate was making news.
0:00:34 > 0:00:37But of course, weather was making news as well on Thursday.
0:00:37 > 0:00:40That stormy start to the day, more snow showers around too
0:00:40 > 0:00:43but then look at this - this is something else that would
0:00:43 > 0:00:46get us talking into next week, a change to milder weather
0:00:46 > 0:00:50and for a time next week, I think, much milder weather for some of us,
0:00:50 > 0:00:52with temperatures actually rising above average.
0:00:52 > 0:00:54The reason for that change coming up.
0:00:54 > 0:00:57But right now, we're very much still in that cold air
0:00:57 > 0:00:59coming on this brisk north north-westerly flow
0:00:59 > 0:01:03across the UK. More snow showers, in fact, more significant
0:01:03 > 0:01:06snow piling up into the hills of Northern Ireland and Scotland,
0:01:06 > 0:01:08but further accumulations to lower levels in places,
0:01:08 > 0:01:10into the Pennines, too, at times during Friday.
0:01:10 > 0:01:13A few wintry showers dotted about through other parts
0:01:13 > 0:01:16of Wales and western England and, of course, it feels cold,
0:01:16 > 0:01:18particularly in the wind and especially across the
0:01:18 > 0:01:22northern half of the UK. But even where you stay largely fine across
0:01:22 > 0:01:25some southern and eastern spots, it's still a chilly wind.
0:01:25 > 0:01:28Those wintry showers continue on Friday night.
0:01:28 > 0:01:31Then we look to the south and we see an area of wet weather affecting
0:01:31 > 0:01:33Wales and southern England that could have a bit of sleet
0:01:33 > 0:01:36or wet snow associated with it clearing away on Saturday
0:01:36 > 0:01:39and actually, Saturday afternoon is much quieter.
0:01:39 > 0:01:41Far fewer wintry showers affecting northern parts,
0:01:41 > 0:01:44more of us dry, sunny, but still cold.
0:01:44 > 0:01:47Icy start to the day and again possibly on Sunday.
0:01:47 > 0:01:50But then this comes in on Sunday, the first onslaught,
0:01:50 > 0:01:52if you like, of the attack of milder air.
0:01:52 > 0:01:55It comes with wet weather spreading north-east into cold air.
0:01:55 > 0:01:57So, some sleet and snow on the leading edge,
0:01:57 > 0:02:01which could be quite heavy in places, so absolutely keep checking
0:02:01 > 0:02:04the forecast if you've got travel plans on Sunday.
0:02:04 > 0:02:07That pushes away, the milder air starts to take over
0:02:07 > 0:02:10the UK. Another weather system, some uncertainly about the position,
0:02:10 > 0:02:13looks like it will run through parts of England and Wales
0:02:13 > 0:02:16as we go on through Monday. North of that it should stay fine,
0:02:16 > 0:02:20notice temperatures continue to creep up at average, at least,
0:02:20 > 0:02:23for the time of year. And milder still by Tuesday,
0:02:23 > 0:02:25with a lot of fine weather around on Tuesday,
0:02:25 > 0:02:28maybe just a weather system glancing the north-west parts
0:02:28 > 0:02:31of Northern Ireland and Scotland, more of us in double figures.
0:02:31 > 0:02:34And so again, that's the bigger change next week,
0:02:34 > 0:02:37to something much milder and above average for some of us
0:02:37 > 0:02:40for the time of year. And it's all down to a change
0:02:40 > 0:02:42in the position of the jet stream. Right now,
0:02:42 > 0:02:45much of the UK is on the cold side of the jet stream on this
0:02:45 > 0:02:48north-westerly flow. But gradually going into next week,
0:02:48 > 0:02:52the jet stream has a different plan. Ushering that milder air
0:02:52 > 0:02:55from the south-west, it begins to pull its way northwards,
0:02:55 > 0:02:58leaving much of the UK on the warmer, the milder side
0:02:58 > 0:03:01of the jet stream. And that's the most significant change
0:03:01 > 0:03:02in our weather next week.
0:03:02 > 0:03:05It will still be unsettled but that change in the position
0:03:05 > 0:03:07of the jet stream actually pushes most of the weather systems
0:03:07 > 0:03:10towards north-western parts, parts of Northern Ireland
0:03:10 > 0:03:12and Scotland in particular, predominantly in the form of rain.
0:03:12 > 0:03:15Relatively dry towards the south-east of the UK after
0:03:15 > 0:03:18Monday's rain and actually climatologically that's
0:03:18 > 0:03:20closer to what we might expect for the UK
0:03:20 > 0:03:22at this time of year. So maybe for a time next week,
0:03:22 > 0:03:25weather and climate converge. Now the change to the milder
0:03:25 > 0:03:28weather will have us talking, not sure it will make
0:03:28 > 0:03:30too many news headlines, though.
