Jan-Feb is basically like Vancouver in spring. Low 20's in the day, high teens at night
A few weeks ago it was really cold, colder than Vancouver in fact (down to 6 when vancouver was 7) but I think those days are over.
If you're used to Van weather anyway, you won't need down jackets and scarves. Only people who just lived through a hot summer will feel extra cold. I remember last time I went back to Vancouver in June, I needed to wear a jacket and pants when everyone was out in shorts and t-shirts
