The setup over the weekend has changed a bit. The once strong MSLP projected to be near 50W/50N has adjusted N/weaker when moving up in time. So while guidance has caught up w/the fact that the system can't push through confluent flow into Canada, there are ramifications to this.
This development would tend to delay the "transfer" of the surface LP towards to northern Mid-Atlantic/SNE coast. With these developments in mind, interior & northern New England would become ideal locations to see a notable snowfall in this setup.
However, locations in SNE down to NYC should still pay attention. There is a decent chance to see a measurable snowfall here & any subtle synoptic changes on guidance over the next few days may lead to further adjustments. In other words, no slam dunk w/this atypical evolution.
Lastly, the warm air advection advancement into areas below freezing will likely cause icing/IP issues across parts of NPA/NYS. Though this is a finite detail that'll be resolved on mesoscale guidance w/regard to impact/precise locations closer to event start.
LP, not MSLP* - rush job.
