A weather phenomenon, known as sudden stratospheric warming, could soon bring a cold spell to the UK.
Hard frosts, bitter winds and daytime temperatures struggling to get above freezing could all be on the cards thanks to sudden stratospheric warming.
According to the Met Office, sudden stratospheric warming describes an event when rapid warming occurs high up in the stratosphere. This can cause the jet stream to ‘snake’ more, creating a large area of blocking high pressure.

Usually, this happens over the North Atlantic and Scandinavia meaning the UK suffers a long spell of dry, cold weather.
When will the sudden stratospheric warming happen?
The latest forecasts are showing that a major sudden stratospheric warming is now likely to take place. Prof Adam Scaife, Head of Long-Range Forecasting at the Met Office, said: “There is now over 80% chance of a major SSW occurring.
"Although the impact will become clearer nearer the time, any effect on UK weather is most likely to occur in late February and March.”
