Next Week's Weather In Detail

The first week of December has been a rather chilly one, reminding us that meteorologically speaking we are now in the winter season.
There has been snow in places too, mainly over northern parts of the UK, particularly the Scottish hills and the Pennines.
South-east England has seen a little snow at times too, including this morning.
It's not usual to see snow in December; in fact, on average the UK will see snowfall on around five days through the month.
Although the weekend looks to be a little milder, computer models have been hinting, for some time now, that next week will be even colder.
High pressure looks to build across northern parts of Europe, called a blocking high. Its exact position will determine how cold it will get and where it will snow.
There's now much more confidence that a north-easterly flow will bring cold air to the UK next week, but snowfall details are much more uncertain at this point.
Initially, North Sea coastal counties will have the greatest risk of wintry showers, even at low levels.
There's a chance of some significant, disruptive snow across parts of eastern Scotland and eastern England.
Many central and western parts of the UK will start the week dry, but there's a chance of something wintry later.
Temperatures will continue to fall through the week and will struggle to reach 2C by Thursday - and it'll feel even colder in the wind.
Expect severe overnight frosts too, with a continuing risk of ice. Rural areas will see temperatures plummet, particularly where there's any lying snow.
By the middle of December, computer models diverge. Some keep the cold wintry theme going, while others bring in mild and unsettled conditions.
You don't have to look too far back in the records to find a cold December. In 2010, the UK had its coldest December in over 100 years, whereas 2011 saw the mildest December since 2006.
The cold spell expected next week isn't likely to be as severe as that seen in December 2010, when Altnaharra recorded a minimum temperature of -21.3C.
