The Met Office are forecasting snow will fall over parts of the UK tonight.

The forecaster is also expecting widespread overnight frosts for much of the UK, with a “risk of snow for some regions”.

Met Office Chief Meteorologist Neil Armstrong said he expects some snow to fall tonight, as cold air from Scandinavia turns the UK much colder in the coming days.

He said: “We’ve already seen snow settling in parts of eastern Scotland and northeastern England.

“As the cold air continues to spread across the UK we also expect to see some snow over the high ground of southwest England overnight tonight and through tomorrow.

“Snow showers will continue along the North Sea coast with a northeasterly air flow, leading to further accumulations over higher ground. Where the showers fall as rain there is a risk of icy patches forming overnight with temperatures widely dipping below freezing.

“A number of National Severe Weather Warnings have been issued and these are likely to be updated through the week so stay up to date with the forecast for your area.”

The Met Office, along with the UK Health Security Agency (UKHSA), have also issued cold-health alerts for parts of England over the next week.

The alert is in place until Tuesday, December 5, with average temperatures forecast to be less than 2C during that time.

The Met Office also forecast wintry showers, icy conditions and some snow for areas covered by the warnings over the next week.

Amber warnings have been issued in three English regions: the North East, the North West, and Yorkshire and the Humber.

While yellow warnings are in place in the East Midlands and the West Midlands.

Dr Agostinho Sousa, Head of Extreme Events and Health Protection at UKHSA, said: “With a risk of widespread overnight frosts and some snow across the country this week, it’s important to check in on the wellbeing of those most vulnerable to the cold.

“Cold weather can have a serious impact on health, particularly older people, and those with pre-existing health conditions, as it increases the risks of heart attacks, strokes, and chest infections.

“If you have a pre-existing medical condition or are over the age of 65, it is important to try and heat the rooms where you spend most of your time in, such as your living room or bedroom.”

What is an amber cold-health alert?

Under the new cold-health alert system introduced by UKHSA and the Met Office, an amber alert means that cold weather impacts are likely to be felt across the whole health service for an extended period of time, with potential for the whole population to be at risk and where other sectors may also start to observe impacts, indicating a coordinated response is required.

What is a yellow cold-health alert?

A yellow alert means that any impacts include the increased use of health care services by vulnerable populations and an increase in risk to health for individuals over the age of 65, those with pre-existing health conditions, including respiratory and cardiovascular diseases and some other vulnerable groups, such as those sleeping rough.
