There are times when camcorders and cold weather don聮t really mix. The problem is two-fold. First聴and this isn聮t solely an issue for camcorders聴cold weather cuts the performance of batteries. So you get less run time than normal, and if it gets REALLY cold, the battery might simply shut down. So that聮s one issue. The other is the cold weather can have a direct physical impact on the camcorder in several ways. The tape may actually shrink, distorting the recording. And it can cause moisture to condense and even freeze inside the camcorder, causing all sorts of problems with the electronics. That can be pretty serious.

Still, I think you聮d generally be OK if you kept the camcorder protected as much as possible聴zipped inside your jacket, for instance, then retrieved for a shot when you聮ve established a position and set up what you want to tape. But riding with the camcorder out, using it when it聮s snowing, or getting that great action shot when somebody blasts snow at the camera聴well, nah. I wouldn聮t do that. So, of course, that precludes all the fun stuff.
Your best solution is some sort of weatherproof case. I like the 聯soft” cases from EWA Marine (ewa-marine.com), which are made of reinforced polyethylene bonded to an optically correct viewing port that attaches to the lens. A waterproof bag, in other words. They聮re available for most camcorders on the market, and, depending on the model, cost anywhere from $200 to $500. You also can take them snorkeling or scuba diving down to 33 feet.
Ikelite (ikelite.com) makes extremely reliable hard cases that are waterproof to 200 feet. But they聮re pricey聴around $600, typically.
