My lack of optimism is less about what an 18z gfs showed and more about the fact that no model is really showing a significant snow event for I95 corridor.
Wow looks like March 2018 all over again, snow and mix all around the rain in the 5 boroughs

It’s not perfect but the RGEM usually isn’t way off and if anytung is usually too warm so it’s a good model to rule in snow chances if it shows somehung good.
