Part of me wonders if this is a bit overdone on the northern extent. Have to watch the area outlined in the Slight Risk by the SPC. How much convection and how organized the convection becomes will be critical. This could rob much of the moisture.
The sfc boundary is also pretty far south, however, it does appear there is a warm front aloft displaced much farther north (through central New England) so this could certainly be a focus for heavy precip north, but I think the convection would end up robbing alot of that moisture. There is some decent vort moving through though.
