BY FAR the best thing you can do is put four snow tires on that car. Take it from me, I grew up in Cleveland, right on the north coast where we got horrible weather fronts rolling down from Canada right across Lake Erie which tended to magnify the effects tenfold!
I highly recommend the Michelin Pilot Alpin A2. Very competent tire. Alternatively, the Nokian Hakkapeliitta 2 is an awesome snow tire. Made in Finland, so you know its designed well. Only problem with the Hakkas is their rather limited availability. Go to

Oh, weight in the trunk wells helps too. I use bird seed so when spring rolls around I can keep our feathered friends happy
