It's early in the season so we can jump on some of these model runs. This one runs a low pressure up the east coast. It closes off, but doesn't appear to get too intense. This is the only model at PSU that shows this solution so don't anyone get all excited

It's fully and completely non-tropical, even the UKMET, never gets close to being tropical, and has no chance to be tropical. It's an asymmetric cold-core storm the whole time on that run...(which is as far from tropical as a low can get)...consult

(Which is a pretty interesting site.)
It's just a run-of-the mill baroclinic East Coast coastal storm, of which there are dozens and dozens every year. In fact, the low center is NEVER actually over water (consulting the most recent UKMET run, the 21/12Z run, newer than your link) so I'm mystified how it is of any tropical interest at all.
