Probably going to be a lot of mixing for the NW suburbs, but it isn't the end of the world. This is a generic high end advisory, maybe low end warning event N&W of I-95 per the Euro, unless I'm missing something. It absolutely stings to lose a big storm inside of D5, but this event is shaping up to give a lot of people more snow before December 20th than in the past 2 winters. Climo in this area is a b*tch. Longitude and elevation are you friends when living here.
