Large parts of the UK are set to experience a dramatic change in the weather this week. It comes as the Met Office has issued a snow warning for large parts of Wales, Scotland and England as cold air moves across the UK.

According to the Met Office, there could be as much as 25cm of snow in some areas of the UK, but most areas on lower ground will only see around 2cm of the white stuff. On Wednesday a fresh amber weather warning was issued for parts of north Wales and Shropshire on Thursday. You can read more about the weather warning here.

The full warning reads: "Snow is expected to develop during Thursday morning and become persistent and at times heavy before slowly easing later in the day. As milder air begins to arrive from the south, there is a chance that snow could turn to freezing rain across some higher routes above 200 metres.

As of Wednesday, February 7, there are two weather warnings in place for Scotland. The Met Office has issued a yellow weather warning for snow and ice from 3pm on Tuesday, February 6, until 12pm on Wednesday, February 7. They have warned that snow showers and ice could bring some difficult driving conditions and localised transport disruption in areas in northern and central Scotland.

Their second yellow weather warning, which is also for snow and ice, has been issued from 4pm on Wednesday, February 7, until 10am on Thursday, February 8. The snow showers could affect northern Scotland, with up to 5cm of snow possible on higher ground, particularly the northwest Highlands.

Meanwhile in England, the Met Office has issued the same yellow weather warning that has been issued for northern parts of Wales from 6am on Thursday, February 8, until 6am on Friday, February 9. Residents in the East Midlands, north east England and north west England have been warned that a period of snowfall could bring some disruption on Thursday and into Friday morning.

The warning has also been extended for Northern Ireland, with all six counties told to be prepared for snowy, wintry weather between Thursday and Friday. The weather warning has been issued for the same time frame as England and Wales.

With this in mind, we've taken a look at the Met Office weather maps to see where and when will the snow fall in different parts of the UK. Alternatively, you can see exactly where and when Wales will see the worst of the snow in the latest weather maps here.
