Hundreds of schools in Britain remained closed for a second day today as more trains and flights were cancelled after further snow fell in the coldest night of winter so far. The UK's overnight low into this morning was -12.5C (13.8F) at Marham in Norfolk; while London, Birmingham, Bournemouth and Southampton all fell to -8C (18F). Severe conditions again disrupted road, air and rail travel on the morning commute today with some train lines blocked after heavy snow drifted onto the tracks. LNER told passengers travelling between London King's Cross, Leeds and Edinburgh to 'defer travel until further notice' due to a broken rail, and also issued a separate 'do not travel' warning between Edinburgh and Aberdeen because of significant snowfall. #snow #uksnow #weather
