CMC, GFS and UKMET definitely show less northern stream involvement compared to 12z. It's subtle but heights over the Great lakes are higher during the storm.
A good reason to be cautiously optimistic.
There a 3 small disturbances merging here.
Models have been pretty consistent with the northern and southern ones. However they've been all over the place with the middle disturbance. Luckily it was never going to be a huge event.
