Wrap up - Met Office warns of Siberian blast and freezing weather
Time to put on your woolies: a sheep near Muir of Ord, Inverness, yesterday

It’s time to get out the thermal underwear and thickest pullovers – Britain is set for shockingly cold weather for at least the next couple of weeks.
After a glorious Christmas, with not a hint of a snowflake, temperatures have been slipping steadily downwards, with minus 11C (12F) recorded in Aviemore, in the Highlands, on Saturday night.
The plunge into a Siberian blast of cold will worsen in the coming week as raw easterlies freeze the country. “This coming week, maximum daytime temperatures will be between 2C (36F) and 4C (39F) but temperatures at night could be well below zero for many places,” said Stephen Holman, forecaster at the Met Office.
The freezing conditions are being swept down from a strong high-pressure system anchored close to Scandinavia. Like a boulder firmly stuck in a river, this anticyclone is refusing to budge and sending our usual wet and windy winter weather on a wide detour, a system known as a blocking weather pattern.

Although it will feel bitterly cold, conditions will also largely be dry, at least for the next few days, and no significant snowfall is expected, although northern and eastern regions could experience some snow.
Exactly how cold it will become largely depends on where the high pressure sits and how much cloud it drags off the North Sea. And cloudy skies are needed, because they act like a duvet cover, helping to prevent some of the heat loss from the ground. If the nights turn clear and winds are light, though, temperatures could plummet as low as minus 10C (14F) even in the South of England in the next fortnight.
In winter, low pressure tends to dominate over Iceland and high pressure to the south, over the Azores. These two pressure systems dance in tune with each other and drive our winter weather, in what is known as the North Atlantic Oscillation (NAO). When the Icelandic low and Azores high are strong, they steer wet and mild weather over the UK; but when they slacken off in a negative phase, that turns the UK bitterly cold. At present the NAO is turning negative, sending a powerful signal that the weather is set to continue cold.
How bad could this winter sink? The weather maps are a chilling reminder of some our most savage winters, such as the notorious 1962-63 winter, the coldest for 180 years. This was when the sea froze around the coast of southeast England and crops were dug out of frozen ground with pneumatic drills and blizzards paralysed the nation.
