Realistically, how much is going to change in a system like this in the next 24 hours? Your weighting right now looks good and is unlikely to change beyond some noise.
Is this going to be one of those extremely rare instances that the Nam is right? I don't think so. I have yet to see other guidance moving north towards the Nam. It's getting late in the game now for that, as we are only about 30 hrs from start time.
Very much like the 21z RAP, with the sleet line barely getting here and into BOS. Looks like the mesos as well as the big boys are in agreement here, all except for the Nam.
