I've also heard about those snow anomalies, here in Sweden much inland and in the mountain regions the snow depths are quite big, not due to cold weather what most people think, but to milder and more moistrous conditions, which have been here the whole winter. And because of the avg. temps a normal year inland are around -10'c in the winter, a few degrees more doesn't make any difference, the day temps just stay more close to zero by giving bigger intensity when it snows. But if you live more near the coastal regions like Stockholm and Oslo and so on, the winter climate becomes much more sensitive, a few degrees more completely ruins winter since avg temps are just a few degrees below zero. And because of that the winter here where i live has mostly been completely snow free. Just a few snaps with snow depth for a couple of days, but really nothing special. February is the month here you think should be very cold with snow and -10'c days, but now it is a +4'c outside, warm sun and chirping birds, nothing i can remember i've seen in my life this far!
