Sunday begins with heavy rain and snow affecting southern and central areas. The snow is mostly to the north of London and stretches up towards with Lancashire and Lincolnshire. There is a big temperature gradient with much milder conditions to the south of London leading to rain not snow. Northern areas are very cold and dry.

The radar view shows the precipitation area at 07:45 GMT. Pink and green shading gives an approximate idea of where sleet and snow is falling.

This morning the precipitation continues and the mild air mass may edge a little farther northwards and with it the boundary between rain and snow. Further heavy snow is expected in the Midlands and down towards the northern home counties. Significant transport disruption is expected. This afternoon the rain, sleet and snow becomes more fragmented and pushes southwards.

The Meteo France Arpege forecast chart shows where the rain, sleet and snow is expected to be at 13:00 GMT today.

A Buzz update was issued at 16:10, Saturday 9th December.

Mixed week ahead

Monday may bring more rain, sleet and snow to the south eastern corner and further accumulations possible. The rest of the UK should have a bright day with wintry showers in the north and around the coasts. It will be very cold.

During Tuesday, Wednesday and Thursday it stays changeable. Temperatures remain on the low side but it will be less cold than recently.

Through Friday and the weekend a northerly air stream probably returns. High pressure will be pushing in from the west so there should be a good deal of dry and cold weather around, although there is the possibility of wintry showers.

Milder by Christmas?

As we approach the Christmas period forecast confidence is low and medium range computer ensemble models show a wide range of outcomes. Most are pointing towards a milder period but there is still a low chance of high pressure becoming established and colder conditions winning out.

A colder winter on the way?

The TWO winter forecast has been issued and suggests a colder and drier than average season. This year it has been particularly difficult to reach a conclusion. Buzz looks at Sunday's snow risk. TWO's fourth winter discussion update has been issued. The winter forecast covering December, January and February will be issued this week.

Christmas countdown

TWO's annual Christmas Countdown continues.
