chef, that's not a tropical feature. see how the clouds are all streaked hard northeast? there's a strong jet stream overhead. there's also a stationary frontal boundary in the area... the old convection was part of that.. today a non-tropical low is deepening in the area. it's bent or bulged, streaked look is called a 'leaf' signature, which is the first phase of a mid-latitude storm. if you get a chance to look at visible shots today, watch the non-streaked, discrete low level clouds (should be cumulus and such). the presence of frontal boundaries and the fact that upper energy out of the west (if you look on wv you should see a turning in the atmosphere quite clearly.. upper low) is spawning identify this as clearly nontropical. for systems started in this manner to transition to tropical they need to occlude or be cut off over warm waters.. out of strong upper level winds.. usually for a few days. this one should move northeast and slow down near the canadian maritimes.. precludes it from ever making the grade. call it a late noreaster.
