I'll open a new thread at 17:00 and lock this one.

These GFS bitterly cold north westerlies are a nonsense no chance it will be that cold and snowy in reality. 

Looking at the more reliable time frame in less than 3 days time:

Many of us will either wake up to a covering of snow or see snow falling so even if this blocking doesn't properly Materialise then at least we would all have seen some snow by the middle of next week on the plus side? - albeit wet and sleety!?
