00:00Hi there, some unseasonal weather coming along for Wednesday, wet and very windy in places

00:06as well. But before that happens, well actually Tuesday is mostly fine but not entirely. We've

00:12got the legacy of a frontal system giving a lot of cloud for southern Scotland, northern

00:15England, outbreaks of light rain turning to moderate or even in places heavy showers by

00:19the afternoon. One or two showers elsewhere, particularly towards the south and south-east

00:23of England, but a lot of dry weather and the cloud will break up in a few places to give

00:28some sunny spells. Low 20s where that occurs in the south, high teens further north. But

00:33the first signs of a change on the way for the Scilly Isles into the south-west of Cornwall

00:38by the end of the afternoon, outbreaks of rain and a keen breeze starting to arrive

00:43here. That rain, moderate to heavy, pushing through south-west England into Wales, northern

00:47Ireland by the evening and then across much of the rest of England, Wales into southern

00:52Scotland by dawn. So turning wet and increasingly breezy overnight, northern Scotland avoids

00:59the rain and with clear spells here and lighter winds, temperatures falling into the single

01:04figures. Elsewhere it's double figures, teens I think by dawn in many spots because of the

01:10breeze and the rain. The main rain is pushed ahead of this area of low pressure which is

01:16going to move across England and Wales during Wednesday. But the strongest winds will be

01:20on the southern flank of the low, particularly for northern France but also for coastal counties

01:25of England. So it's a breezy start on Wednesday, the winds picking up further as the main band

01:31of rain clears north into northern England, southern and central Scotland, pushing through

01:36northern Ireland. I think there will be again some longer spells of wet weather affecting

01:40southern areas but generally it's showers by the afternoon and those showers will be

01:45lively with the risk of hail, thunder and lightning across Wales and central parts of

01:50England in particular. Slow moving downpours could cause some impacts with the risk of

01:5440mm in a few hours. We'll see light winds through these central areas, hence the slow

02:00moving showers, but the showers will be pushed along quite quickly across southern counties

02:05where the winds will be reaching 50mph. So very unseasonal and certainly could cause

02:11impacts where we've got people camping or partaking in outdoor activities, particularly

02:17around some of these exposed coastal parts of southern England. Otherwise it does tend

02:23to brighten up and where we do see some brightness across central areas it will feel reasonably

02:28warm away from any of those downpours. The wet weather continues across north-east England

02:34into the evening before eventually fizzling away and showers replace the rain into Thursday

02:40and Friday. It's also going to turn much cooler later this week. So August starts off

02:46with some very un-August-like weather.
