If you plan on driving in cold weather ONLY, then you'll be okay with the occasional jaunt on the summer tires. You will have much decreased grip though. If you'll be seeing any snow though...don't run the OEM summers at all. Get a set of cheap wheels with all seasons to switch on before you make the trip. They'll handle the occasional snow and cold fine.
As someone living in a cold climate please take my advice. I've driven in the cold/snow on summer tires, all seasons, and snow tires. They all have their place and all are dangerous in the wrong conditions. A $30k car is not worth losing over $1k in wheels/tires.
