Stew,
Glad you made it home OK.
I heard the roads got pretty bad up there on Tuesday.
I've had a few similar white knuckled experiences. One time in particular when I also was away and had to drive home from the airport late in the evening with an unexpected snow storm.
That's why I got a set of all-seasons which do OK in the snow.
My plan for next year is to get another set of wheels with some snow tires to use for the winter, but a friend sent me this link a few days ago.

Interesting option for just the scenario you described.
