The UK is set for more mild weather before a “snowbomb” hits from December 27 with rain and snow for parts of the country in the final “major” storm of the year
Brits are set to be blasted by wind, snow and rain as a “major storm” hits the UK in the final week of December.
It has been an unsettled few weeks with Storms Arwen and Barra battering the country with snow blizzards, gales and freezing temperatures which left thousands of people without power.
There have also been mild temperatures with the mercury rising up to 14C last weekend due to a tropical plume heading from the Azores and Spain.
Now the unseasonably warm temperatures are set to continue this week before a snowbomb hits after Christmas in the final storm of the year – but five more are predicted before winter is over.
It may be bad news for anyone hoping for a white Christmas but the freezing temperatures are expected to hit on December 27 with Netweather.tv stating that there is “potential for some snowfall” due to wet and windy weather heading in from the south-west.
If the 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.
Netweather.tv 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.
“So there is potential for some snowfalls, but not a certainty, as much depends on the specifics of the wind direction and the extent of cold air masses over the near continent.”
Jim Dale, British Weather Services meteorologist, said that the warm North Sea mixed with cooler water from the Pacific Ocean due to the La Nina effect is causing the unsettled weather.
He told The Sun : “We are expecting one more major storm this month which will set the trend for coming months.
“We expect five to six storms to hit through the winter period which could be severe enough to warrant naming.”
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.
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.
The Met Office has stated that it is likely to be drier over the next few weeks and there is a possibility of frost and fog for Christmas.
It predicted: “High pressure, already across southern areas, is expected to build further north, pushing the remaining wind and rain away. Here any rain will be light, giving a much drier second half to December for all and winds expected to be predominantly calm.
“Although rather cloudy at first, cloud amounts should reduce through the period, especially in the south and southeast. Temperatures near average to start, and locally mild in the north, although they will tend to become colder in time for Christmas, especially in southern areas. As a result, the risk of frost and fog increases, the fog slow to clear through the mornings, and perhaps lasting all day in some places.”
