0:00:04 > 0:00:06Hopefully nothing too extreme over the next few days.
0:00:06 > 0:00:09Fairly typical February weather in fact. A bit of a nip in the air.
0:00:09 > 0:00:11Cold enough for a bit of snow at times.
0:00:11 > 0:00:13That's been the case over the last 24 hours.
0:00:13 > 0:00:16Weather Watchers have been sending in pictures.
0:00:16 > 0:00:18This one from South Wales, on Tuesday afternoon,
0:00:18 > 0:00:20a dusting of snow at Tredegar.
0:00:20 > 0:00:23The reason for the chilly air, we've got a run of north-westerly winds.
0:00:23 > 0:00:25It's not desperately cold,
0:00:25 > 0:00:26but just about cold enough
0:00:26 > 0:00:28for some of those showers
0:00:28 > 0:00:29to fall as sleet or snow.
0:00:29 > 0:00:31Various fronts coming down in the flow,
0:00:31 > 0:00:33pepping up the shower activity at times.
0:00:33 > 0:00:36Many of us in between fronts on Wednesday,
0:00:36 > 0:00:38which means plenty of fine and dry weather.
0:00:38 > 0:00:40Sharp showers across the far South-West,
0:00:40 > 0:00:42wintry showers across the north of Scotland.
0:00:42 > 0:00:45Any showers elsewhere, fairly isolated.
0:00:45 > 0:00:46A feel-good day in fact.
0:00:46 > 0:00:48Out of the breeze and in the sunshine
0:00:48 > 0:00:49not feeling too bad.
0:00:49 > 0:00:515 to 9 degrees north to south.
0:00:51 > 0:00:52On into Thursday.
0:00:52 > 0:00:55It could be a frosty start for many of us,
0:00:55 > 0:00:56but a lot of dry weather.
0:00:56 > 0:00:58Area of clouds floating around,
0:00:58 > 0:01:00and one or two wintry showers,
0:01:00 > 0:01:02mostly across the north of Scotland.
0:01:02 > 0:01:04But many of us will stay dry.
0:01:04 > 0:01:07Then the fun starts as we approach the weekend.
0:01:07 > 0:01:08If you watched yesterday,
0:01:08 > 0:01:10you know there's a lot of uncertainty in the detail.
0:01:10 > 0:01:12And that's an understatement.
0:01:12 > 0:01:14Low pressure trying to push in from the West
0:01:14 > 0:01:16and it's south-western UK
0:01:16 > 0:01:18most at risk from rain on Friday.
0:01:18 > 0:01:20How far north and east it gets
0:01:20 > 0:01:23is open to question. Many places dry,
0:01:23 > 0:01:25but with a nagging easterly wind developing.
0:01:25 > 0:01:27That'll be a feature over the next few days.
0:01:27 > 0:01:30One area of low pressure slips away
0:01:30 > 0:01:32and another one will take its place.
0:01:32 > 0:01:34Again, it's the more south-western
0:01:34 > 0:01:35parts of the UK on Saturday
0:01:35 > 0:01:37most prone to seeing wet weather.
0:01:37 > 0:01:40That cold easterly wind elsewhere, it looks as if
0:01:40 > 0:01:42they'll be a lot of dry weather
0:01:42 > 0:01:43the further north and east we go.
0:01:43 > 0:01:46But feeling cold, just four or five degrees.
0:01:46 > 0:01:48Those low-pressure systems
0:01:48 > 0:01:50are in association with milder air
0:01:50 > 0:01:52trying to push the cold air away.
0:01:52 > 0:01:54Where the cold meets the mild,
0:01:54 > 0:01:56there is the possibility
0:01:56 > 0:01:58that some of the rain turns to snow.
0:01:58 > 0:02:02But we are really no further to clarifying that scenario
0:02:02 > 0:02:03than we were 24 hours ago.
0:02:03 > 0:02:06Certainly some rain around in the South particularly,
0:02:06 > 0:02:10and that risk of snow as it bumps into the cold air.
0:02:10 > 0:02:12What we do think is that as we get
0:02:12 > 0:02:14into the early part of next week,
0:02:14 > 0:02:15low pressure drifts away
0:02:15 > 0:02:17and we get a run of cold northerly winds
0:02:17 > 0:02:19sweeping across the whole country.
0:02:19 > 0:02:22So in some senses we're more confident about early next week
0:02:22 > 0:02:25than we are about the weekend. The blues take over,
0:02:25 > 0:02:28so it will turn cold for all of us through the early part of next week.
0:02:28 > 0:02:31Quite chilly in a blustery wind as well.
0:02:31 > 0:02:32It means we'll see
0:02:32 > 0:02:34some widespread frosts overnight.
0:02:34 > 0:02:37But with time, plenty of dry and fine weather.
0:02:37 > 0:02:41Eventually next week, it does look like turning more unsettled,
0:02:41 > 0:02:43milder, cloudier, with some rain.
0:02:43 > 0:02:46Milder air will try to push in off the Atlantic
0:02:46 > 0:02:49to displace the blues and push the cold air away,
0:02:49 > 0:02:52but there's a huge question as to how quickly that happens.
0:02:52 > 0:02:54As is often the case
0:02:54 > 0:02:56when we're trying to get rid of a block of cold air.
0:02:56 > 0:02:58It all hinges on the jet stream.
0:02:58 > 0:03:01The jet stream is there, it's ready to tip us over the edge,
0:03:01 > 0:03:05but how quickly it does that all depends on developments
0:03:05 > 0:03:07the other side of the pond in the Atlantic.
0:03:07 > 0:03:10And there's huge dips, huge meanders in the jet stream,
0:03:10 > 0:03:12as you can see, Stateside.
0:03:12 > 0:03:14When you get those meanders in the jet stream,
0:03:14 > 0:03:17there's a lot of uncertainty as to how quickly that jet pushes
0:03:17 > 0:03:20the mild air across the country. So what we say about next week
0:03:20 > 0:03:22is that it will be cold and frosty to start with.
0:03:22 > 0:03:23How long it lasts is another matter.
0:03:23 > 0:03:26We've got to look to West, to the jet stream,
0:03:26 > 0:03:28for clues on how quickly that mild air returns.
0:03:28 > 0:03:31I'll update you again tomorrow.
0:03:32 > 0:03:35POUNDING BEAT, CHATTER
0:03:35 > 0:03:39Get ready, because BBC Radio 6 Music Festival is heading to Bristol.
0:03:39 > 0:03:42We've got a mind-blowing mix of bands playing.
0:03:52 > 0:03:53CHEERING
