This thing is starting to ramp up as it moves east too. 50-60kt 925 S winds will move into E/SE MA later this afternoon. So I think the longitude hurts a bit until the low level flow starts to back and close off in the GOM.
Some of the mesos get the sfc low going a little sooner and back the sfc winds for S NH and NE MA before it exits. That may keep it cold enough for more accums.
btw weenies...you can get it here...

The settings can be a little confusing and take awhile to setup, but it's pretty cool once you get it going.
I could see some initial sticking issues ASH-MHT-maybe CON with a little insolation and temps just above freezing. Maybe one of those melting on contact dels for awhile and then it becomes a slushy coating.
