As you may remember, a couple days ago the Euro was dumping us with snow this coming weekend. In following runs it was a lot less enthusiastic and more south, coming in line with other models.
However in the latest runs of the GFS, Euro, NG, and Canadian, the track has moved north. The Canadian so much so that it shows the main band of snow to our north and the Ottawa area has a change over to rain. Now I don't think that will happen. I think the Euro and GFS will be more correct with the storm track just south of the lakes, giving us a 10-15 cm dump on Sunday.
Look for forecasts for the weekend to change later this afternoon once the models are processed into the forecast.
