Starting the turn at hr 108. GFS has been rock-solid at this range for awhile, no major changes from previous runs.

It's under an anti cyclone which is moving in the same direction.

Turn starting right on time, ridge is gone. It's going to be similar to the previous run through 5 days and after that I don't believe it anyway. :D Will be interesting to see the Euro tomorrow morning.

Big difference downstream...at 114 hours the cutoff low is now centered over Western Ohio versus over Central Pennsylvania where it was on the 18z.

I don't see how this makes the sharp turn, that it has shown on all these runs. Unless I am reading the chart wrong posted on the last page the High looks to strong to allow it to make such a sharp turn.

That shear is the outflow of the storm. Of course that map shows shear. Plus, it's an analysis map, not a forecast map.

Had that map not showed high shear ahead of this, then the RI would be bogus

Not to mention each run of the GFS this gets a little farther west before the turn commences.

starting the turn 2-3 degrees farther west, is a fairly significant change. Whether it will have major impacts on the future track is to be determined, however

If anything a more cut off low (the 576 dm line is closed here instead of open on the 18Z run, and the low center is still back in OH) increases the chances that 97L recurves down the line instead of the ridge building back in time.

That's a pretty significant shift west in the GFS

00Z GFS would be truly a nightmare scenario.

Yes it is, and yet I was expecting a further west shift than shown thus far. It may well take a more NW motion as it approaches far W. Haiti. Really beginning to deepen at this point too.

Looks like a direct hit on the Haitien capital.

The 0Z GFS at 150 hours is in a similar location that the 12Z Euro is in at 216 hours...only difference is that the GFS is much faster.

Well with the GFS proclaiming the end of civilization in Haiti it is time for bed. Gosh I hope that doesn't happen.
