A rare weather phenomenon known as a \u201csudden stratospheric warming\u201d could see Britain hit with snow and freezing temperatures.<\/p>\n
Following the two recent cold snaps a new and more extreme spell of snowy weather could arrive in the middle of February, according to the Met Office\u2019s Alex Deakin.<\/p>\n
Normally, high-altitude polar vortex winds keep icy air locked up around the North Pole. But a weakening of those winds, allied to a slow-down in the jet stream, could \u201crelease the beast\u201d and send a blast of Arctic weather our way.<\/p>\n

And Met Office forecaster Alex Deakin says that there\u2019s a 25% chance the polar vortex could weaken so dramatically it triggers a sudden stratospheric warming [SSW] \u2013 with the upper atmosphere warming up and sending a mass of bitterly cold Arctic air towards the British Isles.<\/p>\n
<\/p>\n
The SSW phenomenon last happened in January 2021, when it sent temperatures in Aberdeenshire plummeting to an incredible -26C, \u2013 the coldest temperature recorded in the UK for almost 30 years.<\/p>\n
Alex says that the latest computer models show an SSW is a very real possibility.<\/p>\n
Even without an SSW phenomenon, forecasters say we can expect mid-February to be lower than the -10C recorded in parts of the country this week.<\/p>\n
And while we might have to wait until February for fresh snowfall, we can certainly expect frosty mornings for the next few days.<\/p>\n

On Wednesday January 18, the UK Health Security Agency (UKHSA) has extended the current level 3 cold weather alert until tomorrow (Monday 23) at least.<\/p>\n
Dr Agostinho Sousa, Head of Extreme Events and Health Protection at UKHSA, said: \u201cCold weather can have a serious impact on health, particularly older people and those with pre-existing health conditions, as it increases the risks of heart attacks, strokes and chest infections.<\/p>\n
\u201cDuring this period, it is important to check in on family, friends and relatives who may be more vulnerable to the cold weather. <\/p>\n
He added: "If you have a pre-existing medical condition or are over the age of 65, it is important to try and heat your home to at least 18\u00b0C if you can".<\/p>\n
