The board is quite today everybody reflecting on what is persisting south of Cuba?.
While I agree with the board's resident mets that this flare up has all the signs of instability along a trough there are a couple of things that seem to indicate this could be more than that.
Persistence is not a good thing especially over warm water, and this shows no signs of lifting out. It has developed a moisture envelope that suggests a developing low level feature. It has deep tropical source for that moisture. There are several surface areas of instabilityin the area, one especially northwest of it. The trouginess seems to be breaking down and lifting to the North as moisture spills in from the west.
Finally according to Bastardi this morning the GFS develops a low and moves it into the Florida Big Bend in 72 hours.
We should watch this area closely, as I see it transitioning somewhat.
