3km is a tricky distance in the cold. In my experience it takes about 1.5 km to get warmed up while riding in cold weather. So if you dress warm enough for the first 1.5 km you'll be too hot for the last half. For my commute, I dress much lighter so that I'm pretty cold for the first 1.5 km, but my commute is 15 km.
Unless you're willing to stop halfway and take off a layer or two, you'll have to choose between being too cold for the first half or too hot for the second half. My personal prejudice is being too cold for the first half (since I hate to get to work sweaty!) Best of luck either way!
A good windbreaker will help immensely. Get one with pit-zips, they really make a difference. Don't get anything waterproof. My 2 cents.
