The Met Office has issued weather warnings for London as forecasters said there is a "high risk" of snow in the capital.
After another mild day on Wednesday, temperatures are expected to plummet overnight and it will feel a lot colder on Thursday morning.
Snow is expected to fall after midday when a band of rain coming from across the channel hits the cold air.
A Met Office forecaster told the Standard: “The main concern for Thursday is the risk of snow.
"Initially we were uncertain that it would happen but now it is looking pretty likely.

The greatest risk of snow is in evening, which could cause problems for commuters during rush hour.
Motorists are also warned there could be icy stretches on the roads.
