The possibility of snow could cause travel problems in the UK as temperatures decrease.

There is a possibility of heavy snowfall later this week in certain areas of the UK, potentially causing disruptions. Higher regions may experience up to 20cm of snow.

The Met Office has announced a yellow snow warning for a large portion of Wales, as well as northern and central England, as temperatures are expected to decrease throughout the week.

One to two centimetres is widely possible at low levels, 2-5cm on ground above 200 metres, and as much as 10-20cm above 400 metres. The warning runs from 3am on Thursday to 3am on Friday and stretches from Cumbria and the Scottish border down to Cambridgeshire and the Midlands in England.

The warning covers northern and central parts of Wales, including the island of Anglesey. The forecaster stated that there is a possibility of power outages, travel disruptions, and isolation for certain rural areas.

Later in the day, the snow will decrease and could potentially change to rain or drizzle, particularly in the southern and eastern regions.

The Met Office stated that there is uncertainty regarding the boundary between rain and snow, as well as the northern extent of snow.

The deputy chief meteorologist at the Met Office, Chris Almond, stated that although there will be rain in the beginning of this week, it will gradually move south and there is a higher chance of wintry conditions later in the week as cold air from the north comes over the UK.

“It’s from Thursday that the snow risk becomes more potentially impactful, as mild air attempts to move back in from the south, bumping into the cold air and increasing the chance of snow developing on the leading edge.

Although there are still many specifics to be determined, it appears that the initial likelihood of snow is greatest in the northern regions of England and Wales starting on Thursday.

The precipitation will transition from snow to a mixture of sleet and rain as the warning period comes to a close, originating from the southern region.

The forecaster stated that additional advisories for ice may be given later this week due to below-average temperatures for this season.
