This week starts with high pressure and ends with low pressure so the weather will change from frosty and sunny to cloudy and wet. Alex Deakin talks us through the switch.

00:00Hello. Welcome to your weather for the week ahead from the Met Office.
00:03Two very different sides of autumn on show this week.
00:06We're going to start with crisp chilly mornings and a bit of fog,
00:10but also plenty of sunshine.
00:12However, slowly but surely,
00:15the weather patterns will be changing.
00:17And so by the end of the week,
00:18well, it won't be as cold, particularly at nights,
00:20but it will also be a lot cloudier and also a lot wetter.
00:24So we're starting the week dry and fine,
00:27thanks to high pressure,
00:28although there are weather fronts in the far.
00:29Southwest and they tend to take over the isobar,
00:32squidge together, telling us at times it will be windy.
00:35And these weather fronts will be providing bands of rain from Thursday onwards.
00:40Let's take a look day by day, though, focusing on Tuesday.
00:43First of all, a cold frosty start for many,
00:46but that weather front in the southwest still providing some outbreaks of rain
00:49and not completely dry across the east, a sprinkling of showers.
00:53But for many, it is a fine day on Tuesday after a frosty start,
00:57certainly from the Midlands, northwards and rural areas.
00:59By the afternoon, temperatures perhaps just a touch higher than Monday's values,
01:03more widely into double digits,
01:05still generally around or below average for the time of year.
01:08And the winds, again, a big feature in the far southwest.
01:12That wet and windy weather coming from this weather front,
01:15which bumps up against the area of high pressure during Tuesday and into Wednesday.
01:19And it's given another little push later on by another weather front.
01:22So again, we'll see quite a bit of cloud in the southwest,
01:25southwest England, south Wales and a bit more rain just slowly edging northwards.
01:30There's that second push of heavier rain coming in perhaps later in the day.
01:35Again, though, for much of the Midlands, eastern England,
01:38northern Ireland, a good part of Scotland by the odd shower.
01:40It's generally dry and bright with some sunshine around after a frosty start.
01:45Temperatures, again, just about struggling up to double digits.
01:48Milder air arriving in the southwest.
01:50But of course, there will be cloud and rain here once more.
01:53That's from this area of low pressure,
01:54which continues to edge its way in during Wednesday and into Thursday.
01:59Now, there's nothing really giving that area of low pressure much of a kick.
02:02So these weather fronts don't look as if they're going to provide significant heavy rain.
02:07But of course, because it has been quite wet recently, any rain won't be too welcome.
02:12And these bands of rain will slowly edge their way northwards.
02:15Still some fine weather, perhaps across the far northeast.
02:17But overall, for many places, Thursday is a lot cloudier.
02:20And even as the rain clears, it'll turn quite misty and murky.
02:24But it will be warmer with temperatures up to 14 or 15 degrees Celsius.
02:28Now, a bit of uncertainty about the exact progress of these low pressure systems
02:32come the end of the week.
02:33But it looks like we'll see one moving through the country during Thursday and into Friday
02:37and then another one perhaps arriving as we go into the weekend.
02:41Both will provide some outbreaks of rain.
02:43And at times, with those isobars getting closer together, it looks fairly blustery.
02:48So the end of the week will be very different to the start of the week.
02:50Spells of rain swinging across the country.
02:52Of course, there will be dry and brighter periods in between.
02:55But strong winds are possible.
02:57We'll keep a close eye on that as those low pressure systems arrive.
03:00But it won't be as cold, particularly at night and first thing in the morning.
