Here's a link to "Weatherbase". It shows historic weather data by month, by town within each state over many years. Temps default to "C" degrees, but you can select "F" if you wish. It's a free app. On Streets and trips, I selected Winnipeg to Tampa, FL. and exclusively expressways. Looks like a little over 2,000 miles. Even Nashville, TN averages below freezing temps and one or two days of snow in Dec. and Jan. And if it doesn't snow anywhere along your route, coming or going, finding a CG along the way that's open will be like rolling dice, hoping for a 7. If you get past all that, you still have to find a CG in Florida with an opening. Good Luck.
