Lee is about to blow open the hurricane/MH days stat. Looks like all those bullish seasonal forecasts will verify. 

If this were to verify, i assume that would be catastrophic surge into Boston harbor?

They take the comments on Americanwx and feed them into ChatGPT to get an artifically intelligent forecast

Sounds like then it would show a 880mb storm riding up the east coast merging with a polar vortex causing a blizzard with 170 mph winds. 

All major models now showing yet another potentially strong CV storm about a week behind Lee, NOT the current NHC marked orange.  Looks like we're getting our answer of which will win the El Nino vs hot Atlantic...

18z euro ensembles definitely more sw than previous runs...

Fortunately for CONUS it appears about to recurve in the run.

Yeah, still, it's not often you see Euro going to 917 in a long range forecast.  This thing is gonna be a quite something.

06z GFS decimates the northeast...

18z GFS with a carbon copy of Floyd

12z euro brings this down to 935mb. That's pretty unheard of from euro this far out. 

Lololol NHC literally said "no way Jose" in their discussion. 

But back in topic, GFS and Euro ensembles bring this MDR system awfully close to the east coast. Looks like we could get the first legit long tracking CV storm to threaten the US since... Irma?

Man this place died off after landfall

Not much to talk about 

Head back to the 2023 thread, got another MDR system coming in the models. 

Euro, CMC, Icon, and UK all show MDR development in 5 days. I wonder when we get a new lemon. This looks like it could be a long tracker ACE maker. 

There's a nasty feeder band about to come through my house in Boca Raton.  Should get interesting.

So the strongest winds are in the NE eyewall.  Flight level recorded 71 kts, dropsonde recorded 68 kt at surface, although it had some mid-80's in between.  Still not overly impressive.

SE eye dropsonde recorded 63 kt at the surface with max flight level wind of 65 kt.  Where is NHC getting 80 mph from?  Seems like even calling it a hurricane is a stretch based on measured winds.

I'm still reeling from the GFS and ensembles bust from last year taking Ian to the panhandle instead of Sanibel/Captiva. Whether it's Hurricane Irene 1999, Hurricane Charley 2004, Hurricane Ian 2022, they always seem to move eastward as they are influenced by the trough in the Eastern Gulf of Mexico.

GFS for the most part was the outlier for Ian. Lots of other models had it going between Tampa and Ft Myers. All the models are in agreement with Idalia.

I know all the focus is on the initial landfall, but how much should we start looking into the fact that this thing might loop back around after it exits the east coast? What is the likelihood we get a 2nd landfall next week?


.

I'm looking at that too.  GFS deterministic showed it happening and Euro has roughly 1/3 of the members doing it.  Only thing is it seems it would be pretty weak at that point.

Just 50mb off for Franklin.

lol well Euro always has trouble with intensity.  But this is when GFS was seeing nada in the Caribbean.

Just putting this model image out there, from August 20, eight days ago, for this exact time stamp.  Compare to current satellite...this is why Euro always reigns supreme.

I think the 18z GFS showed this too and a hit at around Jacksonville Florida at the end of the run of all things.

Nah the GFS shows and Franklin Idalia both long gone at that point, it looks like the tail of a front that gets left behind and develops. 

There are now 5 or 6 EPS members looping and ending with Franklin moving southwest back towards the US...

They are going to have to retire "I" names altogether.

Lol just make it like the 13th floor of buildings

So, the 12Z EPS has 4 members out of 51 (8%) with a landfall south of the Big Bend and N of Tampa Bay, the most dangerous track for Tampa Bay. That's nothing to take lightly but there's lots of hope it won't happen as the odds are quite low based on this.

I gotta think even if it makes landfall around the Cedar Key area, with it forecast to be a large and east heavy storm, that would still bring in significant surge into Tampa Bay. The Tampa folks here can tell you they get surge flooding from anything more than a small breeze.  

12z EPS with a significant shift south and east. Got a bunch of members going right through Tampa Bay and even more just to the north which would push the surge right into the Bay.
