hello there. snow has been falling across the hills of scotland through the night. that will continue although it is tending to peater out. we could have several centimetres towards morning. also fog is going to be an issue for those travellers on friday morning, quite thick patches in place, reducing the visibility. that s because we ve had a lot of mild and moist air move northwards on thursday. the weather fronts bumping into the cold air in scotland, that s likely where we re going to see the snow. that boundary will come further southwards on christmas day. some fog under the clearing skies further south whether it s at least milder but it s the light winds we ve got an issue with here. so going through the day on friday, we ve got that mild air with us, the fog issue is slow to clear and then our rain starts
