You would like the GGEM if it wasnt so terrible with hurricanes ;)

Anyway, I agree with you about the tenths of degree... could make a difference if 94L heads toward Carrib/YP or EC

Yep-- your extrapolate that tenth of a degree, and five days later, it's hundreds of miles!

I've been thinking for the past few days that 94L will eventually end up in the Gulf, whether via FL, Cuba, or possibly even the Yucatan Channel. The digging trough along/off the west coast of N. America this weekend into early next week teleconnects strongly to increased ridging over the eastern US. I see it as unlikely that there would be a weakness strong enough to shoot 94L northward like the GFS has been showing.

Awesome-- so glad to hear this. :)

Nice to see the ECMWF back to reality again... again the 500 hPa ridging is much stronger on the ECMWF in comparison to the GFS, which should keep it on a more westerly track, perhaps even slipping south of most of Cuba.

Yummy!

I am in agreement with your thoughts. While the GFS has preformed better than the ECMWF with regards to TCs this year, it has not with mid-level ridging, especially with this system. The ridging that builds back in suggests that 94L should stay further west.

Here is a little blog update with some of my thoughts.

http://philstropicalweatherblog.wordpress.com/2012/08/21/invest-94l-poised-to-become-a-tropical-cyclone-invest-95l-and-96l-on-opposite-sides-of-the-atlantic-basin/

The main story, the model disagreement over how much ridging will be over 94L in five days. The GFS has a large weakness the system moves northward in, while the ECMWF keeps it on a westerly course with a narrow ridge remaining in place. If I was a betting man, I'd place my bets on the ridge hanging tough considering the model bias with this storm so far to weaken ridging too quickly.

i'm thinking it'll delay the start, not dissipate this system. but i do like the convective trend. just would like it to fill in a bit more. and as well, that dry patch to the northeast of the convection does make me wonder how fast it'll develop before this system makes it to the leewards. the environment looks better west of the leewards than east.
