The 1987 set up is nothing like the synoptics over the next couple of days, 87 we had huge convection in extremely cold uppers and yes as you said a foot or so of snow was 'delivered' to the south eastern counties particularly coastal areas but what we'll possibly see over the weekend are quite rare synoptics and very difficult to call, where as 87 the writing was on the wall. Not sure about legendary either, 79, 81/82, 86 (for cold in Feb) 87, 91 and possibly Dec 2010 but this I don't think so. But you never know the weather can be pretty unpredictable!
