This guy is legit. He was way more accurate that the NWS last winter when it came to snow storms and snowfall amounts. He predicts the East to have an average scale (and the Midwest to be above average! Score!) But like he says, there's no way to accurately predict weather on a seasonal scale, so it's all pretty much speculation.
