The latest thinking from the very good Liam Dutton about snow for England and Wales:
Whilst most places will probably see rain, there is a chance that as it brushes against the cold Arctic air coming down from the north, it could turn to snow in places.
What is the chance of snow?
At the moment, the chance of snow is considered to be very low – probably around 30 per cent – which means rain is much more likely than snow for most. Also, the greatest chance of snow will be over the hills, mountains and moors of Wales and southern England – especially as the rain starts to clear during Thursday afternoon and evening, as the colder air digs in and temperatures fall away into the night.
Even if rain does turn to snow, it will have difficulty settling because the ground will still be wet from the rain that preceded it and probably not quite cold enough to stop the snow from melting. However, if it does snow, it is likely to be wet snow, with big, fluffy white snowflakes that can reduce visibility significantly and make for tricky travelling conditions.
