First off - glad you are okay. Possibly could have been an overheated rim. On the other hand, had a similar rim failure early this year on my LHT (which is also a winter commuter). My LBS concluded that a small stone (or something similar) got stuck in a brake pad and quickly cut a deep groove in the wall of the rim. Which then failed. Might want to check your pads and make sure nothing is embedded and waiting to chew another rim apart.
