The medium range Met Office update this afternoon is fascinating and highlights the uncertainty in the model output very nicely:
“Monday 12 Jan - Wednesday 21 Jan
This period carries much more uncertainty than usual as milder air from the Atlantic attempts to displace the cold air over the UK. On balance milder, or at least less cold conditions are likely to make some progress into the country by Monday, bringing a spell of snow for some areas, most likely central and northern parts with rain more likely across the south and west, before it either clears or dies out. It’s uncertain as to whether these less cold conditions ever reach the extreme north and east, and here it may well remain cold throughout. Further into next week its likely to remain cold across the north and east, these colder condition possibly extending back into the rest of the country.
