Very busy day here today in the office doing snow warning. I have found some time to issue my thoughts on snowfall.
We favor a blend of the GFS and the ECMWF model for this storm. The expected track of the initial, primary storm is quite favorable for significant snow across southern and eastern Ontario before it gets absorbed by the coastal storm.
Heaviest snow for the GTA will be late Thursday night into midday Fri, then lighter in the afternoon.
Heaviest snow for southern New Brunswick, through PEI and Nova Scotia will be late Friday night into Saturday with blizzard conditions.
This storm should be all snow for Canada, though a little mixing initially near Windsor.
