I know you've got your depressive mood hat on, but that really is pretty amazing considering we're only halfway through winter and we've a cold spell on the way!
March 2013 gave a couple of dustings of snow here, so although it was unusual it wasn't something I'll look fondly on in years to come. The end of February/beginning of March 2005 delivered half a foot of snow here and it snowed every day for 14 days in a row. That's a good 7 weeks yet in which we can get deep snow which hangs around down here. Of course, by then the sun's heat starts to kick in but as long as you have cold enough air aloft, low enough dewpoints and most importantly frequent top-ups....
In the run-ups to 2009 and 2010 there were plenty of ensemble runs going for -10C at 850 for London, albeit only for short spikes. There have been fewer this time around. Also back then the 850s averaged out at around -7C, whereas this time they're clustering around -5C. That said, as long as dewpoints are low enough snow would be perfectly possible with -5C 850s!
