Not a lot of cold weather riding experience, my limits are low 40's and sunny. Not that I wouldn't go colder if I really felt like I needed a ride. I've noticed this fall that to limit sweating it works better to keep hands, feet and head warm, and let my torso be a little cooler. I was surprised when I might have had an extra layer on my torso than I needed, that even though I came home cold, how much sweat there was. This is with pretty breathable layers. The next day when temps were similar I went one less layer on my torso and came home less sweaty.
