Good evening. Friday brought a respite from the wet and windy

weather across the UK, many areas seeing clear blue skies and

sunshine. Under those clear skies now, temperatures are falling away

sharply and we are looking at it widespread frost developing tonight

and some quite stubborn batches of four. That could be an issue first

thing on Saturday and waiting to was the start -- South West with an

amber warning from the Met Office, and area of low-pressure that

threatens for heavy rain. The rest of this evening and overnight,

falling temperatures mean a frost quite widespread, but first thing

on Saturday, we will actually see temperatures coming up a little

towards the south of the UK as the clouds stars to spill in. Further

north, a frosty start, but a beautiful looking start to the day

for Scotland and Northern Ireland without the of sunshine but one or

two areas could get stuck for some lingering fog. Across the North of

England, the Vale of York, a favourite spot for hanging on to

the fog and across the Midlands and the Welsh marches. Across the south,

much milder because the cloud is already in and the rain is moving

in. That is the reason we have an amber triangle on the satellite

picture, a Met Office warning for the south-west of England and parts

of Wales at the moment, where we are likely to see the heaviest and

most persistent rain. The heaviest will not be during daylight hours,

but it will be persistent for southern England moving into Wales

and the Midlands through the afternoon. Further north, a

beautiful afternoon for Scotland and Northern Ireland with plenty of

sunshine but quite chilly. Increasing cloud across northern

England but it is the rain that is likely to be the biggest talking

point to the south of the UK on Saturday, when it will turn heavier

again across the south-west of England and into South Wales. 20-40

mm possible quite widely, in some areas 60 mm, in excess of two

inches. To add to that, strong winds on Saturday evening for the

south-west of England, transferring to the south-east and East Anglia

during the early hours of Sunday, strong enough to potentially do

some damage as they wrap their way around this Bull's eye of a low. It

is not quite quickly on Sunday so for Sunday dined -- day time, dry
