Cor, today is really super ramping from the media about the prospects for tonight/tomorrow. "Heaviest snow in years", "Significant falls" "5-6 inches of lying in London" ....
I am guessing with this much hysteria, it should be the case .....
The frost this morning was harsh in my area but not the worst I have seen strangely enough. Outside thermometer took a reading of -3c, which would certainly be one of the coldest, if not the coldest night in my area.
