It's about 6" or so. Even before today you could walk over the snow and not break through the crust and sink, that's how hard the top layer is. I'd imagine it's even more impenetrable now with today's freezing rain and sleet.
we picked up about 1/3" of sleet again this afternoon. Not far from 2" of sleet in the past week. Snowing pretty hard right now, looks like a good dusting so far. Nice band moving through.
