Brits are set to freeze as an Arctic blast rages over the coming week which will see temperatures plunge and snow expected to fall for days.
And experts have warned people to prepare for an increased risk of flooding right up to January.
Weather charts from meteorologists WXcharts shows heavy snow is predicted to move down Scotland towards northern England from Friday.
This is then expected to fall over higher ground on Saturday, before more snow strikes again on Monday, where it could fall as far south as London and the south east.
And temperatures are likely to plunge with most areas barely rising above zero degrees in the coming days, with the biting weather set to last right up to the weekend.
Long range forecasts at the Met Office predict colder conditions along with ‘wintry showers’ mostly in the north.
On Tuesday there will be showers in the north along with chilly conditions and some frost in places. Southern areas will remain largely dry with some cloud.
Meanwhile, forecasters said the UK is facing a higher chance of a wetter winter in the next few months with households urged to be prepared for the risk of flooding.
The Met Office says there is an above-average chance of the winter being wetter than normal over the three months from November to January, with the wetter conditions most likely in January next year and beyond.
With the potential for more wet weather and impacts from rainfall and winds, the Environment Agency is urging people to check their flood risk online, sign up for flood warnings and, if they are at risk, know what to do if flooding hits their home.
Stephen Dixon, from the Met Office, said temperatures will fall in Scotland and northern England, and then further south as the week progresses.
He told the Independent: “From Wednesday, highs will be around 9C, but lows overnight into Thursday will go down to -4 in rural Scotland.”
Many places will see wintry showers of rain while snow is expected in Scotland and higher ground.
Similar conditions are expected on Thursday and Friday.
“Into Friday the theme continues: a cold start for most with overnight temperatures widely around freezing overnight and in rural areas down to minus two or three degrees,” Mr Dixon said.
