I've lived in New England all my life and I've worked in the DC area. I see all kinds of snow and FWD is just fine -- just keep good tires on it (which you should anyway). Mine came with LS-2s which were adequate. After the first winter I switched to General Altimax Artics which were better. Still, for DC area, the LS-2s are probably all you need. I wouldn't waste money on 4wd or dedicated snow tires.
We're getting 6-10" tomorrow and I'm going to work in my FWD Patriot, and I will get home and I won't bother to clean the driveway. When the snow gets outrageous we do have 4wd available, but that's mostly needed for our driveway, not the roads.
Final word of caution: 4wd is only for starting up in deep snow. You will corner no better and stop no sooner with 4wd. Unfortunately, many people imagine that with 4wd its going to stick to the road better. NOT! In fact, I've heard credible arguments that 4wd provides
less not more traction when cornering.
Believe it or not, my FWD Patriot is better(!) than Wifey's 4WD Wrangler on the highway in snow. Yes the Wrangler will start up on a hill better and faster, but the Patriot will do it too; just lay off the gas cuz power makes you lose traction. When it comes to hills, the Patriot has a 60/40 weight distribution in favor of the front so you ought to be able to find enough traction to climb. On the highway the Patriot has a longer wheelbase, narrower track and narrower tires -- all advantages. You wrestle with ruts in a Wrangler and it is much more likely to dance.
And the other 360 days of the year you're getting 2-3 better mpg. That's a lot of ice cream cones for the kids next summer!
