A number of National Severe Warnings for snow and ice have been issued, further warnings are likely to be issued throughout the week. The initial focus of the most impactful snow is in north-eastern areas of the UK, as well as some Northern Ireland and southern and central areas of England and Wales.

Met Office Chief Meteorologist Matthew Lehnert said: “Snow, ice and low temperatures are the main themes of this week’s forecast, with the UK under an arctic maritime air mass.

“Snow could lead to some travel disruption, with a chance some rural communities in the north could be cut off.

“The focus for the snow moves to southern England and South Wales tomorrow and some may wake up to a few centimetres of snow, with the south coast and far southwest likely to see a mix of rain and sleet. Further snow and hail showers are also expected along northern coasts, especially in northern Scotland.

“During the afternoon, a further spell of sleet and snow is likely to develop across southern England and South Wales which could cause travel disruption into the evening. The impact of lying snow and ice on untreated surfaces may have an impact on Thursday morning travel.”

Cold weather alert

Ice will be an additional hazard for many through the week, with sub-zero temperatures creating some hazardous travel conditions. Temperatures could drop as low as -15°C overnight on Tuesday in some sheltered Scottish Glens, especially where there’s fresh snow cover.

The UK Health Security Agency has issued a Level 3 Cold Weather Alert for the whole of England which is likely to be reviewed in the coming days.

Dr Agostinho Sousa, Head of Extreme Events and Health Protection at the UK Health Security Agency, said: “During periods like this, it is important to check in on family, friends and relatives who may be more vulnerable to the cold weather, as it can have a serious impact on health.

“If you have a pre-existing medical condition or are over the age of 65, it is important to try and heat your home to at least 18°C if you can.’’
