Okay... charts are finally up. I guess I created the thread way before the script was scheduled to run.

these are just so awesome! I think I've told you before, but will again, thanks for all this hard work, senor!

Am I seeing things or is there an upper level low moving over western Cuba and the Cayman Islands???

Not sure, but that tiny little vort max(?)almost on the Belize coast was interesting for at least part of the loop.

First, it's not best to use visible satellite to determine upper-tropospheric flow. Visible satellite using reflection of light and cirriform clouds don't provide the best reflection. Water vapor and infrared satellite is much better at determining the upper-tropospheric pattern since it uses a function of temperature, which picks up cirriform clouds much better.

With that said, doing a quick streamline analysis, it appears much of the Caribbean is under anticyclonic flow aloft. The pattern is a little more rugged near 93L, but essentially 93L is influence by an anticyclone aloft to its east and a cyclone to its west--centered over the Bay of Campeche.

There's a ship N of the Yucatan that is reporting what appears to be abnormally cool water. I'm considering the observation suspect at this time.

It's from ship A8JI3, called the "Prince of Waves" which is a reefer from Liberia.

Their 06Z and 18Z observation both reported 23.0°C, although the two reports come 235 mi from each other. We shall see...

Yup, still reporting 23°C water. I'm dropping the BS flag on this ship. It's funny watching this "cool pool" of water on the 93L wx chart floater archive. It just magically drifts SE along the ship's path.

Oh ok, so that explains the 74 then? I was thinking how could it be 74*F there in June, almost July, and nothing big has moved through recently? O.o

Thank you very much senorpepr. The symbol explantion is awesome too!

That's the problem with "amateur" observations--they're not always calibrated properly.

I like to keep ship observations on because there are few reports in the open water. I don't know one bad apple spoil the rest when there is so little to work with.

Normally I also plot CWOP (Citizens Weather Observation Program) data, but there are a few folks reporting station pressure rather than sea level pressure. That makes it appear as if there was a strong low overhead. Luckily, there is plenty of other METAR and SYNOP stations where I don't have to plot CWOP is there's bad data present.
