Tropical or Not? We may have an Answer Yet...
Canada or Wonderful Canada has a buoy that seems to be directly in the path of this system.

Ok what we are looking for is: (if we get a close pass)
1. A sharp pressure fall over a small perion of time and rapid rise thereafter
2. A rise in temperature near the core and as the immediate approaches
3. Sharp increase in wind near the core (i.e. not distributed like a extratropical system)
Let's see if we have a player...

AS good as we are going to get on this one...
Also, if it was at some point tropical. The fact that it seems to be transitioning and still has some tropical characteristics would make an interesting argument. The extra tropical transition is not instantaneous and hopefully we can get a glimpse...

So far so good, from 1900 to 2100:
Pressure is down 4 mb and winds have increased from 12 to 23 knots sustained.
AND MOST importantly...even though the sun angle is decreasing...the air temp is increasing...I would love to know the dew point...oh well
Same time yesterday the temperature was decreasing right now

Good catch, but isn't the heat increase only at altitude?

sustained winds up to 27 knots pressure fell .18 last hour to 29.80
hope those fisherman are prepared for a "no name warm core system with tropical storm winds"

It looks you may have nailed it drezee.

A warm-core non-frontal synoptic-scale cyclone, originating over tropical or subtropical waters, with organized deep convection and a closed surface wind circulation about a well-defined center. Once formed, a tropical cyclone is maintained by the extraction of heat energy from the ocean at high temperature and heat export at the low temperatures of the upper troposphere. In this they differ from extratropical cyclones, which derive their energy from horizontal temperature contrasts in the atmosphere (baroclinic effects).

I plotted the 00Z surface analysis of the region. Southeast winds and dew points in the upper 60s to low 70s from Maine through Nova Scotia. Not much evidence of a cold front off the Nova Scotia coast. The structure of the low doesn't look frontal, either.

The pressure at a nearby buoy dropped to 1001.2mb as the center passed to the west, with a sustained wind of 31.1 kts. Stronger winds probably passed west of the buoy.
I guess it'll all even out at the end of the season. This one will counter another storm that probably shouldn't have been named.

The HPC hasnt got rid of the front icon, meaning there still is a front there...aka no TC...Take the National Map from the NWS: http://nws.noaa.gov/outlook_tab.php there is your low, connected to a cold front...
