This is a joke, everyone stop panicking about it and calm down, it doesent matter if the BBC have changed their forecast slightly over the last half an hour, the 18z clearly shows what the 12z showed and that is... Rain/snow band getting into the midlands by around 6am, slowly moving north most the day until it stalls around north nottingham/south yorkshire then fizzling out slowly. Theres no need to start calling it a downgrade or a let-down, just calm down it will happen, you will see. It's like one last minute change of forecast and everyones gone into metldown, it will happen as they said earlier and come across the midlands and slowly move northwards, everythings fine.
