Quite the battle between the models. Again temperatures are everything. Majority of models keep the 850s below freezing the entire duration. SFC temps are around freezing and thats where the problem arises. 24 hours out and models still haven't finalized on a proper track.

Seeing ice build up over the lakes is a good sign as it would retain less warmth being spread since the Lakes are cooler. With the fine snow cover we may keep low level cold air in place.

Lets see. It really pins down to a now casting moment.

Nice summary. Very finicky setup it seems. Clearly some minute details in play which the short range models are picking up on. We will find out soon enough.
