Forecasters from the Met Office have explained why December is set to feel colder than ever.

Derek Brockway said: "It's been a mild autumn so far but get your winter woollies ready, there's a change on the way!"
His colleague Matt Taylor added: "Hold tight! Bit of a weather rollercoaster on the way...with a couple of big temperature dips too."
Temperatures in Liverpool hovered around 9C on Friday, but this is set to plummet to 4C on Saturday as the region is braced for an amber wind warning.
The long range forecast for the UK expects that temperatures will remain "mostly rather cold in the north" at the start of December.
