The Met Office has put Sussex on a cold weather alert as freezing temperatures and snow are on their way from Russia and Scandinavia this weekend.
Temperatures in East Sussex look set to drop on Friday January 11 to 2C and will not rise above 5C, although it will feel more like -1C during the day due to wind chill.
At this stage snow is forecast to fall on Saturday January 12 from about 6pm.
Temperatures will not rise above 4C during the day, but could fall as low as 2C. However it will feel more like -4C at night and -2C.
More snow is on the cards in East Sussex on Sunday January 13 from 6am to 3pm.
Day time temperatures will struggle to rise above 2C and at times will languish at 0C.
But due to wind chill factor in will feel more like -4C.
Monday looks even colder at this stage, with temperatures between -2C to 0C, but feeling more like -3C to -7C.
The Met Office said while temperatures were set to be much lower than the last week or so, there was a lot of uncertainty about how long the cold weather would stay with us and exactly which areas of the UK would see snow.
The reason for the cold weather is that an area of high pressure develops over Scandinavia, allowing cold air from the Baltic and western Russia to move towards the UK.
At the same time milder air and Atlantic weather systems are trying to push in from the west, leaving the UK as the battle ground where they meet.
Met Office chief forecaster, Paul Gundersen said: “All parts of the UK will see cold weather setting in over the weekend.
“We can expect sleet and snow showers to affect eastern areas at times, but with a battle developing between the cold air in the east and mild air pushing in from the west, no one should be surprised to see sleet or snow over the weekend and next week.”
The Met Office said there was a 70 per cent probability of severe cold weather, icy conditions and heavy snow between 6am on Saturday and 6pm on Monday in parts of England.
This weather could increase the health risks to vulnerable patients and disrupt the delivery of services. It will be a shock for the county too, which has enjoyed mild temperatures for the last two weeks.
The public should keep up to date with the Met Office weather, as the forecast could change.
