just calculated it for reference in case it's useful to you, the 12z ensembles snowfall probs (would use 18z but it isn't out on meteograms yet) at IAD
IAD probs:
>1" - 47%
>6" - 31%
hour 81, our big-scale features look better so far. blocking comes in faster, whatever semblance of low 50/50 heights we have seems stronger, and that piece that eventually comes in the west and messes w our trough seems more held back
interesting how the same camps snow-wise for the 28th storm are applicable for the 4th storm. for example euro & cmc are both colder and south for the 28th storm in comparison to gfs. i imagine we'll have to wait a few days to see how that storm plays out so we understand how the next storm plays out
this is honestly gonna be one of the last if not the last storms to track for the season (as if we've had any) so idk ab you guys but i'm gonna have fun tracking this
HH GFS frame by frame analysis who's with me
when was this dicsussion posted? bc as of now, both EPS and GEPS show a pretty perfect track in terms of how the NS doesn't outpace or get held back and phase with the SS.
