It depends on low placement / track. Typically speaking... a strong SLP doesn’t bode as well for the coast as it does for the interior. Warm air intrusion can be a big concern. As is my concern with this storm along and east of 95. Stronger typically means a closer track to the coast.
There’s likely going to be a pretty big snow gradient unless this thing begins trending SE a bit. Snow to Rain E of BAL / DC... a few sloppy inches downtown...3-6” just outside the beltway, and 6-12+“ north of 70 and west of 270. Classic December setup. We get that 1040 HP to anchor in the right location however, and coasties get their boom.
Currently, the QPF jackpot is in northern MD / southern PA (1.5 - 2” of qpf looking at deterministic models) - along with the best lift. Need a decent jog SE for I-95 to get in on warning level snowfall unless you live in NJ and points N.
