1978 for the conditions alone is rightfully a storm of lore, but total snowfall in Detroit was definitely a screw hole during that storm with around 9" from the storm and a snow depth of 15" following the storm. Obviously at face value thats great, but considering what happened all around us I actually get annoyed that thats the "go to" storm to talk about. A storm just over 3 years earlier in 1974 dropped 19.3" of heart attack wet snow and does not get nearly its due compared to '78. And of course, as I mentioned just above, Detroit just saw 16.7" GHDII setting the stage for historic cold in Feb 2015. That of course was the winter after the record season snowfall snowfall of 94.9" when snowdepth locally obliterated 1978.
Back OT, whatever does happen Friday and Saturday, frigid cold is lurking right behind it. So this really could be an old fashioned winter blast if all goes well.
