there was a precedant for that sort of situation, assuming it comes about.
Quite a few similar, some a good deal more exciting/damaging. Deep slow moving lows off Cornwall are not that unusual.
E.g

The current developments are rather more similar to those which gave the last real blizzard in Cornwall, wayback in Jan 1987. It's all getting a bit late in the winter though, for it to be a real repeat in the far SW.
Time will tell of course.
