As of now, I would not put much faith into it...;)


I see.

Thanks for the reply. :)

Where will it hit according to THIS model at landfall for the US?



again this is one run of a left outlier....I don't put a lot of stock into it nor do I with the NAM. I usually go with the consensus of al the models.......

GFDN has now shifted westward as well.

And the overall model consensus is now further west too.

How far west are we talking now? Flip/Flop Flip/Flop - I figured that there would and will be more flipflopping.

I think I'm just going to wear my flip flops tonight so I can join in with the models.

I see that EWG.....hmmm I wonder why the shift eventhough the center has been forming N and E all day.

may be the weakness isn't suppose to be as strong? I really don't know. I don't think it has been moving NE today though, I think more of WNW to NW today.

I'm fixing to take a dramamine for the dizziness.

Goodness, it has changed so much just today it is hard to remember what the predictions were for this morning. :?:

Good answer Rock....;)

Let's see how this model handles the benchmarks I mentioned..

We all knew that there would be changes from model to model. The disco at 11 will give us some insight to any change.

Strat, Rock ... count me in. I'm totally in agreement that we should consider some benchmarks and then see how all of these models are doing. That will tell us a lot, methinks.

EWG, I meant the reformation of the center.....but yes WNW or NW today.

Interesting to note, in Derek's latest forecast he went off of this model for his projected path which is westward somewhat....lets see if it verifies....no doubt it is seeing a stronger ridge as does the NAM...

Obviously the ridge is not expected to be that strong or else we would have more mets in agreement and the models would be picking up on this, don't you guys think so?

I think the ridge or more to the point the uncertainty of it is a hugfe stumbling block in the models, and soon, we have land mass issues to further complicate things.

Wasn't it the 12km WRF-ARW that nearly nailed the Katrina forecast last year? The simulated reflectivity was absolutely remarkable beyond 48hrs, picking up the lop-sided-ness it acquired as it neared land. I think the timing was off by several hours, but it was a remarkable forecast and verification.

I'm going to search around the NCAR/UCAR site to see if I can verify this.
