Stationary Franklin
Wouldn't that cause are wave train to curve out to sea by the time they hit 65 or 70w

What "synoptic" are you referring to?
-- What layer of the atmosphere around Franklin right now features a westerly componant? The trough-associated westerlies that dragged Franklin out to where it is are now ancient history, because there aren't going to be any more short-waves "dropping" down the right flank of a stationary heat-dome planted over the central US. The new situation is the high stretching and elongating SW/NE up and over Franklin as a cool front bashes into the northwestern side of the ridge.
I do not think this mid-summer front possesses the strength to just charge right on through the Ohio valley and off the coast; instead the heat-dome/omega-blockish pattern will merely shift east, temporarily east (trapping Franklin under the high) while the front-associated stuff arcs up and over it -- you can see this developing already on satellite.

-- Look at that massive region of subsidence which has set up shop N and NE of Franklin. Ain't nothin' goin' thataway until the pattern putting it there moves on.
There shouldn't be any eastward progess with Franklin until it exploits a weakness in the ridge to the NW and pops to the top side and catches the westerly freight-train. East movement progged from the current location is, IMO, fantasy.
And, westward movement, even sustained westward movement, is not impossible above 30N:
