No need to move nor lock as this is a new area that anyone has posted until now.

That is an upper low that has been in that area for many days.Sometimes upper lows go to the surface but that proccess takes many days.

And now it's looking to flare-up some. How does one tell it's just an ULL and also if it is/isn't moving to the surface?

One easy way is to look at the water vapor loop, if it spins CCW in the water vapor loop which shows the upper levels of the atmosphere, then it's a ULL. On the map below you can also click on the HDW high for the upper level winds.

I was looking at this blob and noticed the high HDW(ULL) but also at the mid- HDW shows some circulation.Not sure, if I'm right?

...especially when the water temps are as cool as they are there...which is on the order of 78F...with no heat content to speak of.

Yeah your right, but that's pretty much the norm.

Isn't a warm core system when the temp of the core is warmer than it's surroundings? Cause I'm not quite sure on that one.

Basically...yes. It is also barotropic in this sense...no temp advection. However...usually for a cold core low to make a tropical transition...you need some really warm waters. The wamer the waters...the less amount of time needed.

That makes perfect sense as in order to get warmer temps into the core of the low it would take waters that are warmer than the air/moisture above the surface of the ocean. So would it take considerably warmer waters or just a few degrees higher than the air temps in the core of the low?

Well...the cold core low is actually in the upper levels...and there really isn't a low at the sfc. However, your water temps warm the entire air column. So...you would want water temps about 5 degrees warmer (at least) than they are now in order to do it in a couple of days...assuming the low stayed put.

OK...on to the shuttle launch and my 4th of July party. Talk to you all later...
