Although when looking at specifically Moncton, it rather looks like the same 1-3cm is predicted with the snow missing us.
On the other hand.....
The position right now suggests 15-25cm snow, while the 24 hour snow is saying 1cm Weds, 2-4 Thursday and 1-3 Friday.
So that's a maximum snowfall of 8cm (or as little as 4) over 3 days compared to a single storm Weds/Thurs of 15-25cm.
That's more than a little different.
