The Met Office said there was still uncertainty about how far the snow could extend into southern parts of England but between 10cm (0.3ft) and 20cm (0.7ft) of snow is predicted across the Scottish Highlands and northern England.
A forecaster from the Met Office said: "Across central and eastern parts it will be colder than average, looking at highs between four and six degrees by day.
"At night time, we'll see temperatures hitting freezing tonight and then see temperatures drop below freezing tomorrow."
Central England and Wales could see nighttime temperatures plummet to -7C (19.4F), forecasters said.
High winds are also expected to sweep across the country, reaching between 40mph and 45mph. Forecasters said the winds will ease for a time on Friday but pick up again over the weekend due to the low pressure system.
Forecasters said the North East of England was likely to see adverse weather conditions due to the boundary of warm and cold air.
It is anticipated the Met Office will issue initial warnings of rain, sleet and snow for affected areas tomorrow.
"We'll see things turn a bit colder as we go through to the end of the week, Friday will be a cold day," the Met Office said.
Looking ahead to the festive period, forecasters said the weather had the potential to be unsettled.
