Monday is off to a wet and windy start in southern areas but in the north clearer and showery conditions have returned. This morning the rain in the south eases off but it remains cloudy. The north has a mix of sunshine and showers which increasingly turn to snow over high ground. Through the day the clearer and colder air in the north steadily pushes southwards to reach all areas by the evening.
Temperatures range from 4C (39F) in Scotland to a mild 11C (52F) in the south. See the rainfall and precipitation type radar for the latest view.
Tonight under clearing skies it becomes cold with quite a widespread frost. Wintry showers continue in the north.
Tomorrow all regions have a cold and bright day but around coastal counties and in the north wintry showers develop. Over high ground accumulations of snow are possible.
During the rest of the working week the UK will be sitting under a cold northerly flow with high pressure to the west blocking the flow of Atlantic weather systems. Wintry showers could affect all regions but most of them are likely to be in coastal counties and the north on Tuesday and Wednesday. On Thursday the risk of snow showers could spread further inland and southwards.
The Arpege chart below shows the majority of showers near the east coast on Thursday afternoon but more of a northeasterly component to the wind direction leads to some of them spreading inland.

By the weekend high pressure becomes centred slightly farther southeast in the Atlantic. That leads to less cold air rolling over the top of it and pushing down across the UK. Weather fronts also bring the risk of patchy rain and that may be preceded by a little snow over high ground.
The ECM pressure and 850hPa chart for Sunday 3rd December below shows milder air filtering down across the UK.

The longer term outlook is uncertain. Quite a blocked picture is expected to remain over the North Atlantic although an increasing number of computer models runs are trending towards a wetter and less cold outlook.
