Read our Weather Presenter Bob Crampton's blog about the cold weather coming our way next week:
This is going to be hard to believe...but the reason for the incredibly cold conditions next week is down to a warming event that's taken place.
A sudden stratospheric warming event happened last week. It warmed the stratosphere by 50C over a few days.
This sudden warming caused a large area of high pressure to develop to the east of the country.
Some newspapers have called it the Beast from the East!
The freezing cold air all the way from the north pole will move across Russia, the Baltics and Scandanavia and really start to affect us over the weekend and next week.
There is the risk of seeing some snow as a result, with more prolonged snowfall over Southern England. Whether it will reach the West Country is questionable.
But it will be bitterly cold next week. Some places will fall close to zero during the day.
Seriously low minus temperatures during the night... It will be the coldest period we've had for some time.
