Cold this morning and any freezing fog will slowly lift to leave some sunshine. This afternoon sunshine will fade as the cloud thickens from the west.
Outbreaks of snow will move in from the south-west. This will become persistent and perhaps locally heavy giving a risk of significant falls in places. The snow may become patchier towards dawn.
Staying cold and quite cloudy tomorrow. There will be a risk of wintry showers, some of which may merge to give longer spells of rain, sleet and snow at times.

Road conditions:

Road surface temperatures falling to around zero tonight – see tables for details/hazards. Some drifting of snow is possible, mostly on hills. Low confidence on the amount of snow.

Current road surface temperature highs at our weather station in M25/M23 Merstham are 2.5°C and lows of -2.6°C in Church Lane.
