A system of fronts is moving over increasingly cold air as it pushes eastwards over the UK. Spells of rain and sleet are more readily falling as snow as it progresses, giving the most significant snowfall of the winter so far for many. Clearer air will follow in behind the cold front later today, giving a widespread ice risk.
