rationale

well, if that synoptic pattern progged next week, with the trough inland and the subtropical high wedged into the east coast... sort of a PNA negative summer pattern like we had in late june... if that's going to be our late monthly recurrent pattern during summer/fall transition then i guess there may be some merit to the idea.
thing is, to get a hurricane into new england like that, that isn't weakened from crossing coastal north carolina... you've got to have the high amplitude ridge in place, a digging trough in the western great lakes, and a hurricane coming in at just the right time. otherwise it'll recurve or push inland further south. that's a timing issue that keeps their strike interval for big ones at 20-30 years.
of course, this recurring weather theme could keep the hydrologic state in the northeast juiced for a major flooding event if a tropical cyclone passes. sorta like what was going on last october and this spring.. and again in late june. all the flooding jazz in the northeast corridor lately does keep the prospect of a hurricane passage causing a huge mess at least believable. you wouldn't need a major or significant hurricane to cause a whole lot of flooding, in such case.
