UK weather forecast: Arctic winds to bring big freeze before ‘snow bomb’ lands

The UK is set for more mild temperatures before a deep freeze over Christmas. A “snow bomb” is then expected to hit from December 27 bringing several centimetres of snow for parts of the country

Brits will need to wrap up warm for a frosty Christmas with sub zero temperatures before a “snow bomb” hits in the final storm of the year.

Forecasters are predicting that the chances are not high for a white Christmas despite freezing temperatures coming from north easterly winds.

As the country recovers from snow and gales from Storms Arwen and Barra, the mild temperatures have continued over the past few days after it reached a balmy 14C last weekend.

But the temperatures are expected to drop over Christmas with “dry air and fog”.

Jim Dale, of British Weather Services told the Express : “The main two factors in the short term will be dry weather and fog. At times the fog will be dense and will sit in valleys.

Weather maps show that the temperature could drop to around -3C on Christmas Day

“In the short to medium period there will be lots of fog. There is no storm potential this side of Christmas.”

Netweather charts show most of the country will have sub zero temperatures on Christmas Day while it could drop to -3C in the west and the north west of England as well as Scotland.

“The main hazard will be ice on roads, this side of Christmas,” said Mr Dale.

“Christmas day will be pseudo-white, a heavy frost on the ground, in bookies language this is the favourite forecast.”

He continued: “It will be a pseudo white Christmas. This means frost instead of snow.

“It will certainly be cold enough for snow, but there will be less moisture in the air to form snow. The weather will become progressively colder as we move towards Christmas.”

From December 27 the UK is expected to be hit by a snow bomb

The mercury is set to drop further from December 27 when the UK could be hit by a snow bomb. If a storm’s central pressure deepens by 24millibars in 24 hours, it will earn the title “weather bomb” which coinciding with snow could drive an eruption of winter downpours. states: “Confidence is lower for this period but there is a greater chance of colder weather heading in from the east at some point during this period as highest pressure transfers further north, most likely towards Scandinavia.”

Weather maps by WXCharts shows rain hitting the south west of England on December 27 with 3mm set to fall in an hour while in the North West it will fall as snow with 1cm expected an hour and more overnight.

The cold weather is expected to come in with north-easterly winds

By midnight December 28, up to 2cm of snow an hour is expected to have fallen across much of the north west and south of Scotland, as well as in Southampton and Cardiff.

Mr Dale said: “After Christmas, there is a northeasterly cold air coming.

“It will get properly cold after Christmas with the possibility of a white New Year. The potential for snow will be high after Christmas.

“There is a cold pool over Europe and we could be left open to this polar air over the New Year.”
