What is a typical winter in Tennesee like? Do you get much snow and real cold temps (like 15-20 degree stuff)
15-20° we could see in a typical winter in NE Texas(at least when I was growing up in Plano).
Not really a whole lot different then Plano winters except the snow will last a little bit longer.
15-20 isn't a stretch for either place. How long it lasts that's something else. A few days, then we would get some "warmer" weather, then a blast or two of the cold stuff.
That is what would generally happen at either spot.
