I like the general broadbrushing and probability forecasts the NWS does, it's much easier to forecast general temperatures as opposed to specific storms.
In addition to that, I wonder if posting past analogs would also help. If anyone posted late 80s analogs, I think people would immediately know what we were dealing it-- at least those of us who lived through that time period.
Such a situation where DC gets more snow than NYC isn't as uncommon as some think. It was much more common in the past, but it can still happen.
