UK snow risk as Arctic air sweeps in

Much colder weather is set to arrive across the UK next week, bringing widespread frosts, plunging temperatures and for some areas, snow.

The weather will start to cool down on Saturday as a cold front pushes southwards, with the air turning progressively colder into next week as an Arctic air mass becomes established.

This change in weather fortunes comes about thanks to a blocking area of high pressure building across Greenland with cold Arctic air emptying out across the UK and bitter northerly winds developing.

The fact that this pattern established itself in late November means we are in for some cold weather for the time of year but temperatures would have been much lower had this system set up in the heart of winter when the Arctic is far colder.
