00:00Hi there, following the very heavy thunderstorms that some parts of the UK saw over the weekend

00:06and a slightly quieter start to the week, we've got more rain to come as Atlantic weather

00:12returns, the first signs of that already into parts of Wales and the south-west, it's been

00:17a damp start to Wednesday, that band of rain pushing into the Midlands, the south and south-east

00:22as well as parts of Northern Ireland by the afternoon. Northern England, Scotland, mostly

00:27dry but it will be increasingly cloudy and there'll be a few showers about, particularly

00:31for Northern Scotland where there will be a cold breeze, although some brighter skies

00:35at times for Shetland and for Orkney. So temperatures in the far north, 10 or 11 Celsius, towards

00:43the south feeling unpleasant under the band of rain but as the rain clears Devon and Cornwall

00:48it will feel warmer once again with south-westerlies and temperatures of 18 Celsius, although those

00:54south-westerlies will bring further showers in through the evening, even some longer spells

00:58of heavier rain overnight and the main band of initial rain pushes into North Wales, Northern

01:04England, Southern Scotland and Northern Ireland where it comes to a rest for some hours and

01:09it will turn increasingly persistent and heavy, particularly over north-east England. It just

01:13about avoids central and northern Scotland where there will be some clear skies overnight

01:18and with the colder air in place, temperatures dropping once again into the low single figures

01:23touch of ground frost around first thing, but in the south it's a mild night with the

01:28south-westerlies and the heavy showers around. Those showers will be with us first thing

01:33across the south coast, south Wales as well, some brighter interludes in between the showers

01:39but across this central swathe of the UK there's this heavy and persistent rain that will accumulate

01:45particularly through the morning and particularly for parts of north-east England. North York

01:49Moors, Pennines, you could see 80mm or so, perhaps more in one or two spots, 50mm more

01:56widely and that could cause localised flooding, transport disruption. But it does ease later

02:02in the afternoon and we'll see again a marked contrast in temperatures across the UK. We've

02:07got the cold air in the north but much milder air further south with temperatures closer

02:12to average in southern England, although with gusty winds and heavy showers moving through

02:18during the afternoon it's not going to feel particularly pleasant if you're caught in

02:21those showers. Then the band of rain moves south and becomes lively once again across

02:26parts of Wales, the Midlands, East Anglia. There is the risk on Thursday night and into

02:32the start of Friday of 30mm in an hour or two and perhaps 40-60mm in several hours in

02:40some locations. A little bit of uncertainty about where exactly we'll see the heaviest

02:45rain but there is the risk again of localised flooding and of course that rain hitting areas

02:50that have already seen some heavy rain through the weekend. It's mild though in the south

02:56with that rain first thing Friday. Colder further north with northerly winds starting

03:02to push south. Those northerly winds will help to clear the rain but it could be a tricky

03:06rush hour through the M4, M5 first thing Friday before the rain eventually eases. Some heavy

03:12showers potentially affecting the south coast for a time but by the afternoon many places

03:17are drier and brighter. There will be showers coming through on those northerly winds particularly

03:21for northern Scotland, Northern Ireland but interspersed by sunny spells and it's going

03:26to feel a lot colder everywhere with those northerly winds arriving and below average

03:32temperatures across the board. Having said that, although it will be colder than normal

03:37through the weekend, much brighter skies return and for many it's a dry weekend with

03:42just one or two showers and plenty of sunny spells.
