I dunno about that, most of my memorable settling snowfalls at this end of the UK often seem to occur at the tail end of January and into early February. In fact, I got to see significant laying snow with even drifting in mid-March 2013 - although that was the last time I got to see actual proper laying snow!
Granted, the strengthening noon time sun at that time of the year mean that once the cold air does move on, the thawing process can be quite rapid rather than ice lingering around. But it is also when the sea surface temperatures around the Kent coast tend to be at its coldest.
