TL;DR

 

Wunderground runs on optimistic models. (totally lock it)

 

TWC barely thinks it will rain during the day, none at night (toss it)

 

NWS point and click sucks, unless you live in DCA where you seem to jackpot with the west (100% lock it)

I usually compare weather outlets before storms and it always seems like Wunderground is the most optimistic about snow, particularly marginal events.

I've noticed TWC is conservative unless the storm is supposed to be a blockbuster, Wunderground goes all in then retreats the day before, and NWS Point-and-Click just sucks.

boy, that looks nice but I'm sure 1) it won't happen as the NAM depicts and/or 2) it never can reach its potential

And it wasn't even all that great verbatim. Nice and cold though.
