The way I see it is we ALL have a decent window between Wed pm to say Tues (or even longer) to see some falling snow and many will see lying snow. This is going to be a pretty unstable air stream coming over the UK so more organised bands of snow showers could form at quite short notice. So if you don't see snow tmr/Thurs do not despair or throw the towel in as something may just crop up which sweeps down from the North esp between Sun to Tue. I live very much in a rubbish area for snow, so to start with I'd be happy with a few half decent snow showers whether they stick or not. Good luck to everyone, let's hope by this time next week we'll all be fairly happy!
