Just in case we didn't have enough blobs to watch...
WV loop shows good divergence and area of strong convection off Carolinas.
Possible sub-tropical action East of Carolinas?

Re: Possible sub-tropical action East of Carolinas?
There is an interesting area of frontal convection off the Eastern Seaboard (near 36N and 67W). It is associated with the tail end of a trough. It looks like a weak sfc low could form in the vicinity, and instability is decent. Personally, I think the upper-air environment is too hostile, and the East Coast mid-level jet could kill its thunderstorm activity. I do think it could influence the mid-level pattern - it may induce a weakness in the mid-level ridging over Bermuda. It would affect the upper-air regime ahead of our future CV wave. Additionally, the developing Caribbean disturbance could create a perturbance in the anticyclones. This plausible scenario could occur if the piece of energy lingers or drifts toward the south.

I wanted to bring this issue to the front.

Look at it now.

Of course, a lot of that is just upper level winds providing a lot of divergence that lets the storms blow up, but it sure is fun to watch...

Pressures are low and winds are up. Look Here
