The Met Office announced that a yellow severe weather warning for snow has been issued, with a warning of disruption to travel and possible disruption to power supplies.
Snow showers, overnight frosts and gales will affect much of the UK, with a specific warning for the south east and London issued for Thursday January 12.
Londoners are being advised to prepare for wintry weather as snow is expected to hit the capital.
Temperatures will drop as low as -1°C by Friday January 13 and will only reach as high as 5°C, so for those heading out are advised to wrap up warm.
The Met Office predict there is around a 15% to 20% chance of snow in London.
Spokesman for the Met Office, Grahame Madge, told GetWestLondon that people should be prepared.
"From 10am on Thursday until 9pm in the evening, we have a yellow warning out for snow," he said.
"We have a weather system that will be moving across southern England, we expect that that will deliver reasonable amounts of rainfall.
"However, there is a chance that as that rain encounters the colder air from further north that there is a possibility, we are looking at around sort of 15% to 20% or so, so quite low risk of that turning to snow.
"But there is a chance, if it settles that obviously that it could cause temporary disruption."
As the weather warning is out during rush hour, commuters could face travel chaos, if the snow does settle.
The severe warning from the Met Office states: "Rain moving eastwards across the south of the UK on Thursday may turn to snow in places.
"Whilst it is unlikely, there is a small chance of snow settling with disruption to road, rail and air services as well as interruptions to power supplies and other utilities.
"Associated heavy rain and strong winds may prove additional hazards."
