Below you can see the highest gusts of wind and rainfall totals recorded at Met Office observing sites from midnight to 2.30pm on 27 December.

Winds will slowly ease from tonight and we are expecting a brighter and less windy interlude over the course of Saturday and for most of Sunday with overnight frosts and sunny spells and a wintry mix of showers.

Another active atlantic frontal system is expected to swing eastwards across the country on Sunday night and Monday morning. A combination of strobng winds and moist air has the   potential to give locally significant amounts of rain which could cause the risk of further flooding.  The wind and rain are expected to clear eastward on Monday morning.

During this period of unsettled weather, people are advised to stay up to date with the latest Met Office forecasts and National Severe Weather Warnings and find out what to do in severe weather so they can plan ahead for the weather in store and make the most of the festive season. We would also encourage you to stay up to date with the latest news on flooding by checking the Environment Agency’s website for the latest flood alerts and warnings.

The Met Office at Boscombe Down, Salisbury Plain, recorded 66.7mm of rain in the 24 hours 9am 23 December to 9am 24 December. This is provisionally a new all time daily record in any month for the station – records going back to January 1931. The previous record was 62.3mm on 16 August 1977.

Today we can expect severe gales across western and northern Scotland, with damaging gusts in places, especially around the coasts.

For Christmas Day and Boxing Day, we are expecting a colder and less windy interlude with overnight frosts and sunny spells and a wintry mix of showers, so there is a chance that some places, especially the higher ground of the west and north, may see a White Christmas. For most of us though Christmas is likely to be green not white.

Another Atlantic depression is expected to bring a further spell of wet and stormy weather to the UK on Friday.

During this period of unsettled weather, people are advised to stay up to date with the latest Met Office forecasts and National Severe Weather Warnings and find out what to do in severe weather so they can plan ahead for the weather in store and make the most of the festive season.

Top ten: Snowiest Christmas days

Snow at Christmas is recorded in two ways – the number of stations that reported snow falling, and the number of stations that recorded snow on the ground at 9 am. The two charts show the snowiest Christmases for both measures since 1959.

Will it snow this Christmas?

17 12 2012

With just over a week to go to Christmas Day we are being asked whether the cold weather will return to give us a white Christmas.

Unfortunately it’s still a little too early to say exactly what the weather will bring to the UK on the big day, but it does look as though the early predictions quoted in the press of snow falling in many places on Christmas Day and more recent white Christmas is “a dead cert” could end up being somewhat wide of the mark.

The current Met Office UK Outlook for Sunday 23 Dec 2012 to Tuesday 1 Jan 2013 suggests that the unsettled conditions we have at the moment are expected to continue until the New Year:

“The rather changeable weather is likely to persist into the beginning of January with low pressure expected to be dominant near the British Isles. The north of the UK is most likely to see colder than average conditions, with relatively typical amounts of rainfall. During the same period, temperatures over the south are likely to be closer to average whilst rainfall amounts may be a little above average. Uncertainty then increases significantly into the final week of the period, with no clear weather type favoured, perhaps indicating less unsettled conditions.”

Of course we will continue to update the forecast as Christmas approaches, with the first forecast for the day itself published on our website later this week.

So if you are in search of a white Christmas signs are that many of us may be a little disappointed again this year, but you can find out more about white Christmases in the UK in the following video:





The forecast for the run up to Christmas

21 12 2010

The very cold weather will continue for the rest of the week, but the risk of snow decreases for most of the UK.

Met Office forecasters said: “There will be further outbreaks of snow over parts of Wales and some central regions of England tonight and into Wednesday.”

Met Office forecasters continued:  “On the run up to Christmas and on the big day itself we will have a respite from the snow. However, there will some severe frosts  and freezing fog patches at night. So, while there will still be snow lying on Christmas Day, the day itself is expected to be dry and fine in most parts of the UK”.

Below is a media forecast for use in print publications. All temperatures are in degrees Celsius and represent those likely to be seen in urban areas. Rural areas are likely to be significantly colder at night. For the latest weather forecasts and warnings you should refer to the Met Office website where regional and location based forecasts are available for the next 5 days.
