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.
