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& #39;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& #39;ll be resolved on mesoscale guidance w/regard to impact/precise locations closer to event start.

LP, not MSLP* - rush job.
