It seems like a much more believable run-- at least in terms of ultimate output of snow. 8ish inches seems more in the realm of what this system is capable of.
Snowing in Northbrook. Mixing in ORD as of 20 mins ago. Dusting on the ground already. Feels like LOT (and some of the hi res guidance) may have slightly missed the cold air advection the the WPC picked up on in their discussion.
