0:00:02 > 0:00:04Hello. Monday was the day of the great British weather divide.
0:00:04 > 0:00:08Northern areas saw crisp, wintry sunshine after a frosty start.
0:00:08 > 0:00:10Southern areas, it was grey and cold.
0:00:10 > 0:00:12Shows up nicely on the satellite imagery here.
0:00:12 > 0:00:14You can see the cloud expanding
0:00:14 > 0:00:16northwards throughout the day. Clear skies remain,
0:00:16 > 0:00:18Scotland, Northern Ireland and northern England.
0:00:18 > 0:00:20But at the same point one time during the afternoon,
0:00:20 > 0:00:23Musselburgh and Bristol both showing two degrees
0:00:23 > 0:00:25but as our weather watchers show you,
0:00:25 > 0:00:27completely different views outdoors.
0:00:27 > 0:00:30And with the sunshine, that two degrees felt a lot better
0:00:30 > 0:00:33in Musselburgh than it did in Bristol.
0:00:33 > 0:00:34As we go through into Tuesday,
0:00:34 > 0:00:36the high pressure that was with us
0:00:36 > 0:00:38on Monday continues to push further east.
0:00:38 > 0:00:40At that allows the winds to go more southerly.
0:00:40 > 0:00:42That has taken the cloud further north.
0:00:42 > 0:00:44So a greyer day for northern England, Scotland,
0:00:44 > 0:00:46Northern Ireland. Misty over the hills.
0:00:46 > 0:00:48The odd spot of light train or drizzle.
0:00:48 > 0:00:51But the clouds low based and low topped in that
0:00:51 > 0:00:54when it hits the hills, say the Scottish mountains,
0:00:54 > 0:00:56the Cumbrian fells and the Welsh mountains,
0:00:56 > 0:00:58it will break up. So, Gwyneth, Anglesey, Cumbria
0:00:58 > 0:01:00and the north and west Highlands of Scotland,
0:01:00 > 0:01:02you'll probably see sunshine all day long again.
0:01:02 > 0:01:05Could it 10 or 11 degrees. A cool day for many.
0:01:05 > 0:01:06Turning milder in the south-west.
0:01:06 > 0:01:08Devon and Cornwall, South Wales,
0:01:08 > 0:01:09by the end of the afternoon
0:01:09 > 0:01:12rain arrives, pushing through N Ireland in the evening.
0:01:12 > 0:01:14Through Tuesday night, into Wednesday morning,
0:01:14 > 0:01:15rain pushes northwards and eastwards
0:01:15 > 0:01:17fairly erratically.
0:01:17 > 0:01:19As skies clear to the south and west of the country,
0:01:19 > 0:01:21into Wednesday morning,
0:01:21 > 0:01:22we'll see fog patches form
0:01:22 > 0:01:24and some icy conditions as well
0:01:24 > 0:01:26following rain earlier in the night.
0:01:26 > 0:01:27So for Wednesday,
0:01:27 > 0:01:29that weather front brings rain
0:01:29 > 0:01:30across eastern areas to start with.
0:01:30 > 0:01:33As there's not many isobars on the back edge of it,
0:01:33 > 0:01:35that indicates there's not much wind,
0:01:35 > 0:01:36not enough to push that off.
0:01:36 > 0:01:37So some eastern areas could stay
0:01:37 > 0:01:39cloudy and damp all day long,
0:01:39 > 0:01:41particularly through eastern England
0:01:41 > 0:01:43and also in Shetland, quite a windy day.
0:01:43 > 0:01:45But elsewhere, some fog will linger,
0:01:45 > 0:01:47but many will have a much brighter day
0:01:47 > 0:01:48on Wednesday compared with Tuesday.
0:01:48 > 0:01:50After in places a frosty start,
0:01:50 > 0:01:52actually quite pleasant when the sun is overhead,
0:01:52 > 0:01:55although temperatures in some of the Scottish mountains
0:01:55 > 0:01:56will stay close to freezing.
0:01:56 > 0:01:58Wednesday night, an area of low pressure with showers
0:01:58 > 0:02:01gets close to the south-west, also the Channel Islands.
0:02:01 > 0:02:03Pushes into France, high-pressure with us,
0:02:03 > 0:02:05not many isobars once again
0:02:05 > 0:02:07and that lasts for the rest of the week.
0:02:07 > 0:02:10Light winds, clear skies at times overnight,
0:02:10 > 0:02:12frost and fog could be an issue by the morning.
0:02:12 > 0:02:15On Thursday, mainly across central and western areas,
0:02:15 > 0:02:17still could be a lot of cloud in the east.
0:02:17 > 0:02:19Many will brighten up, sunny spells,
0:02:19 > 0:02:20a bit cool though,
0:02:20 > 0:02:22temperatures in single figures.
0:02:22 > 0:02:25With few isobars into Friday,
0:02:25 > 0:02:27it's that same repeated process.
0:02:27 > 0:02:28Like Thursday, some will see
0:02:28 > 0:02:30mist and fog to begin with.
0:02:30 > 0:02:32Some of that fog may take a while to shift,
0:02:32 > 0:02:34if it does at all. There will be sunny spells,
0:02:34 > 0:02:37particularly in the west where the breeze picks up later.
0:02:37 > 0:02:38Any fog here should clear
0:02:38 > 0:02:39and that breeze picks up
0:02:39 > 0:02:41ahead of this weather front.
0:02:41 > 0:02:43This is the big question as we go into the weekend
0:02:43 > 0:02:46and beyond - how quickly this one pushes its way in.
0:02:46 > 0:02:48At the moment it looks like the south-west, Wales
0:02:48 > 0:02:50and into western Scotland and Northern Ireland
0:02:50 > 0:02:52are likely to see the rain on Saturday.
0:02:52 > 0:02:54But that could all be further west
0:02:54 > 0:02:56it could all be a bit further east,
0:02:56 > 0:02:58and that's our big problem in the outlook
0:02:58 > 0:03:00as we go through into next week.
0:03:00 > 0:03:04This Scandinavian high pressure, how quickly that relinquishes its grip
0:03:04 > 0:03:06and how quickly this area of low pressure pushes in.
0:03:06 > 0:03:09Most computer models show this does happen, but it's
0:03:09 > 0:03:12the rate at which this happens which is the big uncertainty.
0:03:12 > 0:03:15So we know it looks like most places will see
0:03:15 > 0:03:17a wet and windy spell before Atlantic winds return,
0:03:17 > 0:03:20whether they're westerly on north-westerly,
0:03:20 > 0:03:22pushing us back into sunshine and showers.
0:03:22 > 0:03:25But how quickly that happens and how quickly things turn milder
0:03:25 > 0:03:28is something we'll of course keep you updated on.
