Category Five Hurricane Lee

The more I analyze the Euro and the current setting...Its solution makes sense and I see how it could play out.  Currently The following things are happening:

- Lee is a powerful major hurricane that is dealing with shear, but is also connected to a poleward outflow jet that is providing excellent divergence (thus the explosive convection).

- Margot is a weak disorganized TS that is being substantially sheared by Lee's outflow jet.  This shear will only strengthen tomorrow once Lee intensifies further.  Convection will always keep Margot's low east because of said shear.  This will increase the distance between them and is why the Euro solution occurs. 

Looking forward to the models runs later today.

In 48 she begins entering Franklins wake, so SSTs drop off. Don’t think it ever recovers.

Looking at current SSTs and the NHC path, SSTs don't fall below 29C until after 120 hours. That's when the cooler Franklin wake would have a significant impact. So, until then, they're mainly 29-30C, plenty warm.

I was wondering when this was going to happen. Can't we just go with the 12Z GFS instead?

 

Or other 12Zs, like the inferior JMA, which recurves sharply and never even gets close to Canada. Or the (inferior?) KMA, which skims NS and then hits Newfoundland. Or the ICON/CMC, which hit NS. Or the quite inferior NAVGEM, which heads toward Newfoundland. The Euro is the only one of these 7 op models that hits the NE and the only other run to do so was the 12Z of 9/7.

 But then again why go with any operational in particular? Why do we need a definite yes or no when neither is there this far out and instead why not just go with the idea that Lee bears watching for the continued small chance of a NE hit and a bigger chance for a Canada hit? This is a forecasting discussion. We have these discussions because of the uncertainty.

 The last two UK runs have Lee get as far W as 67.7W. More importantly imo they both don't have the lowest SLP until 0Z on 9/16, when it gets down to the low 940s on both runs. That's quite low for the usually conservative UK and tells me that a significantly stronger storm than the current strength is quite possible even going out a good number of days from now.

Eh, it's a Snow Weenie perspective, where consensus models don't exist and it's some sort of titanic picking-sides model fight.

There is certainly a chance this still hits as far back as the cape...just because I don't favor that, it is a viable outcome. I'm not pushing any agenda. Not sure what that was all about.

Personally, I will go with there is a long way to go and the eastern seaboard, especially N MA and NE need to keep an eye on it. 

Likewise, I will actually disagree with you regarding the potential for RI. I do believe it is there as the structure is actually not bad, despite the beating it has taken. 

Just my 2 cents. As far as you having an agenda? :wub:

Yea, I could be wrong on the RI part...much less confidence in that than the favoring NS over US part. I'm not saying it won't intensify...it may make cat 4 again, I just think it will be more gradual.

I meant no disrespect with my post. Just noticed a bunch of consecutive posts with a specific tone and pointed it out. Thank you for your opinion… carry on

I'm not sure it is fair to label an opinion as an agenda, or banter.

Sorry, it is sure to be a cat 5 again by tomorrow AM and be in Manhattan by next weekend. Is that better? Lol

An agenda implies a vested interest or ulterior motive...like trying to get clicks or followers. Downplaying potentially dramatic weather is not the way to do it from my perspective of a weather hobbyist with a weather blog. Makes zero sense
