Interesting Low off FL Coast

[Justin E. Reed]

I was looking at the Weather Tap and saw something that I figured would be interesting. Dry air caught in the low makes for and interesting satellite annimation. You can also use the NHC satellites for more pics.

Good day,

Huuum - Most likely a meso-low of some sort.

These happen from time to time, very low-topped convection (shallow), do shows up more on Visible than IR.

Just noticed this feature on visible satellite...looks kind of subtropical in nature. Wasn't exactly expecting to see something like that anytime soon, just goes to show how you never know what interesting thing will pop up.

When I first saw it this morning I didn't think anything of it and didn't investigate it further. But when it was still there a few hours later and it became obvious that it was a circulation and not just some arrangement of clouds that resembled one... well by then I was too busy to take a closer look.

It does look neat on visible, but if you look at in on IR it's kind of sad. Pretty cool though that it doesn't seem to be spinning down despite being so shallow.

There is a mid- to upper-level shortwave axis in the area (at least as of 12Z this morning)... some cyclonic turning of the winds between CHS and JAX at 850 mb with the trough axis becoming more apparent at 700 mb and 500 mb.

I'm with Don... with the compact circulation existing beneath a cold core shortwave axis, the little guy looks subtropical. It does seem to be attached to a frontal zone, and as long as that's the case it technically doesn't meet the textbook criteria for a subtropical or tropical system.

But it's still pretty to look at.
