Those seeking cold, snowy winters have been really unlucky in recent years in that there's always been at least one important driving force working against the required patterns establishing.
First it was the solar cycle, then some unhelpful ENSO events (the super Nino; when we benefit from weak to moderate, then a persistent Nina-like tendency even through the weak Nino ocean pattern of last winter) and this time around the big positive Indian Ocean Dipole (IOD) event and the QBO being a bit to slow to transition to the easterly phase from westerly. Looks to get there by mid-late Feb.
The +IOD has weakened a lot in the past fortnight, so who knows, maybe Feb will do something interesting - but only if we see the polar vortex weakened a great deal. No real sign of such in the current NWP modelling range; just the possible brief lower-vortex split... and even that isn't looking as pronounced now (GW should be feeling more comfortable today than yesterday!).
Next winter, we'll be very well placed in the solar cycle and have a fully easterly QBO. The ultimate combination of those two for supporting blocking patterns that bring cold, potentially snowy weather to Northwest Europe (usually with the UK near the edge, as we know all too well!).
So, who's betting that there will be an unhelpful La Nina event 
- although that wouldn't necessarily stand in the way of some notably wintry weather Nov-Dec, as a La Nina can promote strong poleward mid-Atlantic ridges before an eastward shift in the favoured ridge location, to Europe, for Jan-Feb.
This last Nov-Dec, there was a Nina-like atmospheric tendency until nearly mid-Dec, but it was too weak to do more than nudge the jet northward in the mid-Atlantic and southward relative to the UK, bringing us cool to chilly conditions, with a lot of unsettled weather, but without temps even falling low enough for snow away from high ground in some northern parts.
