The Met Office has given its verdict on a "Beast from the East" forecast to hit the UK.
Forecasters say a sudden stratospheric warming (SSW), which could lead to widespread snow, is underway but any impact will not be felt until the first week of March. An SSW is when a rapid warming occurs high up in the stratosphere, the second layer of the atmosphere immediately above the troposphere.
Met office forecaster Aidan McGivern said: "The winds in the stratosphere surrounding the North Pole are expected to reverse, instead of going from west to east they are going to go from east to west", which can essentially lead to higher pressure and therefore colder conditions.
