There is still a lot to resolve when it comes to what we can expect. I would think there is going to be a very sharp cutoff and gradient within the region. It's just a matter of where that gradient resides. There also appear to be two viable solutions
1. An all out rain/flooding event along/south of the Pike as the NAM suggests
2. A two part event where we get one round of heavy rain associated with warm front/strong warm air advection, which diminishes rapidly as the system occludes and then a second round as the decaying circulation passes nearby.
Regardless, the weekend is going to be crap...cool, breezy, cloudy, rain but it's a question of just how crappy and whether we have significant flooding concerns. East facing slopes of the southern Berkshires into the Litchfield Hills could be a secondary max area for upslope enhanced totals.
But if we get fronto aligned just north of Long Island across southern Connecticut and southern Rhode Island I'm afraid flooding could be quite significant.
