Met Office Author: Press Office 17:54 (UTC) on Wed 27 Jan 2021 A battle for supremacy is taking place over the UK, with cold air to the north and east and milder wet conditions to the south and west. A dense pool of cold air over Scandinavia is exerting a strong influence on the UK weather as weather systems from the Atlantic try to extend their influence. In this set up this week, rain will extend across southern and western parts of the UK, while snow is likely to remain a hazard along the leading edge as it ‘bumps’ into colder air further north and east.
