Snow doesn't look bad at all currently, a light dusting. Weather warning was from 6pm until noon in scouseland, so at 3:30am would think they'd have a lot by now if they were ever going to.
It's barely freezing too, 0C, expected to sit right around 1C most of the day from about 9am onwards. It would have a hard time settling.
Completely non-expert hat on, I don't think there's too much threat of this being called off.
A couple of webcams if anyone else sad wants to check them out:
