Sounds to me like the radiator isn't doing its job properly - I've seen it before where the rad works well enough to stop it getting any hotter when the fans are on, but not well enough to actually cool down, unless, as you say, it's cooler outside. Does the temperature fall when you're cruising at 60? We have a place that perform a flow test, flush if possible, and replace the core if not - don't know if it's the sort of service you guys have in the US. It's also worth checking both fans are working.
