Possible sub-tropical action East of Carolinas?

[Ed Mahmoud]

Just in case we didn't have enough blobs to watch...


WV loop shows good divergence and area of strong convection off 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...

QScat shows a little turning near 36N 70W.

Pressures are low and winds are up. Look Here

We need a Floater on it ASAP...

nice big blob

now weakening.

now weakening.

Well it is 2pm so no one was expecting much this afternoon. Not like I'm expecting much period.
