The point has been made that some marinas in the northern most part of your voyage may have the water turned off at the docks. By calling ahead, you can find out if you'll be able to get water (and pumpout services if needed).
If there's no ice on the water in Chesapeake, VA when you leave, I doubt you'll find any further south.
You can research long range weather forecasts at various points along your route to see what to expect.
You don't mention if you have heat on your boat or if you have a helm that's enclosed or protected from the weather. Those would be considerations. Bring warm clothing and blankets, especially if you plan on anchoring over night.
If you can find a warm week to leave, you'll be far enough south that cold temperatures will not be as likely.
