Interesting, not what I'd have expected given the 850s and direction of flow.
The dewpoint charts (via MC, don't think they've rendered yet on TWO?) show what's happened - the lower boundary layer's cold has been shunted away a long way eastwards in the 24 hours before the low arrives, meaning it's rain rather than snow for most.
All moot, of course, as it's ages away, but it'd be disappointing (from a snow fan's POV) if it were to happen as shown.
