The Met Office is warning of frequent heavy snow showers today, with the greatest chance of the white stuff falling between 10am and 2pm.
There is a 50 per cent chance of show between 7am and 8am, then from 10am it increases to 60 per cent chance but from noon the Met Office forecast states there is an 80 per cent chance.
A Met Office spokesman said there could be 'frequent heavy snow showers through the day' and 'significant snow accumulations in places'.
He added: "It will be bitterly cold as a strong easterly wind develops, which will lead to drifting snow and an increasing wind chill."
The forecast is for frequent heavy snow showers to continue through the night, with the easterly wind continuing to strengthen.
It will be extremely cold with a widespread severe frost as temperatures drop to -8C.
Tomorrow, snow showers are set to continue through the day, leading to significant accumulations in places.
It will be an exceptionally cold day with many places remaining below freezing, and there will be a bitter easterly wind.
The severe weather this week is because of a cold blast of air known as the 'Beast from the East' sweeping in from Russia.
