I spent a weekend in Roanoke, Virginia in February 2016, and to my surprise, I received signals up to 170 miles away with minor tropo enhancement due to 70-degree temperatures. Roanoke and nearby Lynchburg, VA are interesting because in terms of TV signals, they are considered one market, being roughly 45 miles apart from one another. For FM, however, they are different markets. Almost all of the Lynchburg signals are not receivable in Roanoke, save for a handful of stronger signals. I believe this is due to mountain attenuation and weak <1 kw signals from Lynchburg.
