You mean posting 840Hr GFS clown maps hasn't lured him back? He probably just came to his senses and realized he can do much more with his life than spending his day analyzing 10 day model runs that flip 180 degrees every 12 hours.. I'm sure he'll be back if something trackable materializes within a realistic timeframe.
What's troubling is the lack of any winter weather to make it worthwhile for decent posters to contribute.
