I used to in St.Lous, MO and the coldest bicycle commute I remember there was Neg. 6 F. However, that was a long time (17 years) ago. Since movinig to SoCal my coldest commutes have been the last few days at 37 Deg.F.
Only my hands were cold on the commute his morning, so I will try heavier gloves tomorrow.
