For the GTA, it doesn't look anything exceptional like you guys in IA and IL. Have fun!
Looking at the 3KM NAM, most of the snow should fall in a relatively short time frame along a fast moving FGEN band. The storm begins weakening rapidly as it move towards our area, so that FGEN band is our only window of opportunity. Potential is there for some lake enhancement but more towards Oakville-Hamilton. I'd go with 1-2" for Toronto proper, for now.
