More than 400 schools are closed today across Scotland as forecasters predict it could be hit by up to 40cm (16 inches) of snow.

Transport minister Humza Yousaf said the amber warnings in force for many areas could be upgraded to red - meaning people should take immediate action to keep themselves safe from the impact of the weather.

Mr Yousaf advised anyone in parts of Scotland covered by the amber alert to avoid travel on Wednesday.

And of course you can get a more localised weather forecast, not only for tomorrow but for the next 14 days at the BBC Weather website.

Other towns are, of course, available.

Scotland will be the focus of much of tomorrow’s snow – particularly in the east and across the central belt.

Blizzards and drifting could occur, blown in by the strong easterly winds.

A yellow weather warning covers much of the country and amber warnings are in place in the east.

The further west you are the drier it will be but temperatures are unlikely to go higher than 1C.

Tomorrow the heaviest snow showers in England will be in the north-east of England where there could be up to 15cm of snow.

Across the south of the country there will be a scattering of snow showers but the afternoon could see some sunny spells.

Maximum temperatures in England will be 2C in the south-west, however the wind will make it feel closer to -9 or -10.

It will be a dry night and clear night in Wales with cold winds bringing the temperature down to -6C.

Tomorrow will see some sunny spells and fewer showers than today with temperatures ranging between -2 to 2C.

However factoring in the effect of the wind will make the temperature feel closer to -8C.

Northern Ireland will experience scattered snow showers – most frequently in the east.

The easterly wind could lead to drifting snow.

Temperatures are not expected to reach above freezing.

So, as we begin to wind up our live coverage, the key question is what is the weather going to be like around the UK tomorrow? There's a lot to fit in, so we'll break it down nation by nation.

Two-year-old Albert Staples is clearly a young man in a hurry so he's harnessed the help of his grandma's sprocker spaniels Buddy and Rocky to negotiate the snow in Eye, Suffolk.

It's the best possible combination of woof and whoosh...

Tonight's big FA Cup match between Swansea and Sheffield Wednesday, televised on BBC One from 8pm, is definitely on, but fans will need a few extra layers with the temperature at the Liberty Stadium predicted to dip to -2C during the match.

At least the club is doing its bit to keep fans warm:
