Trusting OP models outside of 5 days is a waste of time. I'd say wait and see what they look like by early next week. Some ensembles had a spike negative in NAO. I wouldn't count out another quick hitting storm. We can do pretty well when the short waves shorten. Slowly though any signs of a sustained cold pattern seem to be disappearing.
If winter ended today I'd have to give it a C-. Pretty lackluster minus the period in January.
