Hick it can be pretty diverse depending on where the wind is blowing from. South winds will keep it mostly in the 40s-50s. North winds now your talkin teens and 20s. Obviously that will determine the kind of precipitation too. After the first of the year for 10-12 weeks is when it can really go one way or the other.
I was stationed in Norfolk years ago and rode year round on an old Virago 535. I don't remember it ever getting cold enough for the roads to ice, and it never snowed enough to stick... That was in the early 90's so I'm not sure how it is out there now.
