Let's see what tommorow brings with this system.

Good thoughts Cyclone.. as we continue to wait and see.. I wonder if "17" will ever be born lol.. It's so funny how we thought days and days ago that it would be.

Let's see what tommorow brings with this system.

Tomorrow should bring little change. An influx of even colder air will spill out across the Gulf late tomorrow as an even stronger cold front moves offshore. This is just a typical winter-time west Gulf low now. There's nothing tropical about it. It won't separate from the front unless the front dissipates, and with increased CAA in 24 hours that won't happen. It could certainly get stronger with more cold air flowing in tomorrow night and Thursday, but that won't make it a tropical storm.

Now, the question might be if and when will the NHC consider naming this a subtropical storm. It certainly qualifies in that respect. But since the strongest winds aren't hitting the deepwater drilling areas south of Louisiana, they may just let it spin out.

Still looks to me that it is more of an MCC (or MCS) feature associated with a frontal trough at this time. IF anything comes about of this being in the form of a tropical system, it'll likely be a hybrid, but IMO, not subtropical. This area is too associated with the frontal trough.

Uggh...more mis-use of the term "subtropical"....I'd actually commented in chat that I was pleasantly surprised that nobody had incorrectly proclaimed 90L subtropical so far today....

The definition of "subtropical cyclone" from the TPC glossary begins with:

A non-frontal low pressure system that has characteristics of both tropical and extratropical cyclones.

Agree on your last sentence 57.

By qualifying as a subtropical storm, I was speaking of its intensity. Certainly, they don't name lows attached to a cold front.
