Black smoke is usually an indication that your engine was running rich. I run with a ScanGauge hooked up all of the time and one thing that I monitor is the air/fuel ratio. In normal operation it is running at 14.7. During hard acceleration or during a hill climb where the engine downshifts, the mixture is automatically enriched by your engine computer to provide more power and for cylinder cooling.
I think that since your engine is running fine now, that this was just normal operation and nothing to worry about. The white smoke could just be some moisture in your exhaust system which is pretty common during the Winter.
If you have access to a Scangauge, you may want to hook it up and see if your engine is running at 14.6-14.7 during normal cruise on flat land. If you can't do that, I wouldn't worry about it.
