Cyclonic Spin In GOM South of Mobile, Alabama

[EmeraldCoast1]

I haven't been able to find mention of this in another thread, so I have reluctantly started this thread to get some comments from those in the know. I have been a casual observer of the tropics for many years and I don't recall seeing such a defined "spin" that includes thunderstorms. I understand that upper lows and MLC's are not necessarily anything to get excited about, but I thought if it were an ULL or MLC that the cold top storms would not spin? Is this something trying to brew? On the IR loops it looks like everthing within a couple of hundred miles of the "center" (87.5W 27N) of this spin are all moving in a defined counterclockwise motion.

Buoy in GOM indicating rapidly falling pressure. Is this just a T-storm?

Upper-level Low!

possibly working way down though

Doubt it - local mets just mentioned that it would only enhance our rain chances somewhat. Nothing was mentioned about it working to the surface - doesn't seem to be a concern.

Some fairly low pressures in the Gulf with a Ship reporting 29.88(I know they are not always right but a buoy also reporting 29.91. Ship reported 38 mph sustained wind granted that is probably storm related. Still looks to me like this is trying to work its way down. Will have to watch.

I would agree caneman. Everyone is vetting about 97L ... meanwhile this Gulf system looks suspicious. Not saying anything would happen here but it is certainly something we (GOMers) should watch as its in our own backyard.

Looks interesting.

When I look at the visible loop with long/lat on....it seems to be to not be moving anywhere. Just sitting and spinning. Am I right? is it waiting for something to "move" it? Not sure what influences ULL's. THoughts?

Are you using Firefox? I use firefox but this is one those things that I have to do a IE tab to see it.

Will the front that is coming through the South right now move it?

I don't know about your neck of the woods, beachbum ... but the NWS mets here in Texas are skeptical of the GFS' projection of the front dipping that far south. The GFS has been pretty aggressive lately about moving these fronts further south than they actually end up. Hard to say.

I just checked David Glenn's blog from one of our local stations here and this is what he has to say about the ULL in the Gulf. He doesn't seem too worry about it right now except it is going to bring rain to us.

Yes, I am well aware of what the NAM is doing! I say this, because I have had some email from cautious viewers wondering about the "lows" the NAM keeps spinning up and throwing toward the north Gulf coast. The NAM appears to be over developing an upper level low that is about 250-300 miles south of our coast. This low is slowly drifting south, then southwest through Friday. The low is helping to keep us in a moist pattern, but at this point I do not expect the surface development that the NAM keeps showing. I think the NAM is correct in the indication that we are in for some increased shower/t-storm activity through Friday, but that's it.
