Going to Florida

Only time we've hit any "bad" weather was several years ago around Beckley WV. Some snow falling-slowed down to about 45 for about 10-15miles, then good weather the rest of the way. This was around Thanksgiving.

We live near Hamilton and always take the 401 and cross at Detroit to pick up I-75.

Friends of ours from the same area like to cross at Fort Erie and pick up I-71 near Cleveland and head towards Cincinnati to pick up I-75. So many times our friends got caught in lake effect snow off Lake Erie and had to wait out bad conditions in the Erie area. All routes are very weather dependent but the south side of Lake Erie seems more risky than the north side. I-77 is a great route in good weather, but we would never consider it in the winter. As others have said, too many hills and drivers with limited experience in icy conditions.

We've run down 88-81-77-26-95 to Florida in early January for several years, and only once have we held up for an extra night at a planned over night stop. That at Ft Chiswell, VA at the junction of 81 & 77, and we didn't want to risk a run down Fancy Gap hill on 77 due to possible road icing all the way to Charlotte that day. Every other year, we've never hit any real weather, just an occasional brief snow flurry along the way.

I would stay clear of I-77 during that time of the year too many hiils along the route that could meen beter chances os snow and or ice. In addition we found places to stay to be much more difficult to find along that route

I can't help you up north, but living in NC and knowing I-77, I can tell you that it is a hit or miss thing on I-77
You can have 75 degree weather and you can have snow and ice, and the big problem with the snow or ice, is once you get down out of the mountains the road people don't have a clue how to handle it.
One time in December we had snow covered roads all the way to Columbia and there were cars and trucks off both sides of the road.
Just pay attention to the weather reports and plan by them.
