I know it's still early, but local forecasts for my location (including netweather) barely indicate much cloud cover let alone snowfall for the next 7 days or so, so apart from being very cold, snowfall is looking quite minimal at the moment. I mean a couple of cm's is hardly worth getting the snowploughs out for. Personally i've seen this kind of setup many times before, and it does have the potential for quite a severe spell of wintry weather.
