Re: Issac & 24/12Z Upper Air Package

18Z models:

GFS: Crosses middle keys around 2PM Sunday, then clips southwest Florida, and eventually makes landfall again between Pensacola and Ft. Walton Beach around noon on Tuesday, then stalls out moving slowly over AL/MS.

EURO 12Z, Crosses Near Key West Monday around 8AM EDT, landfall near Mobile on Wednesday morning.

HWRF 18Z: ((similar to last nights 18z, but west of earlier runs today) Clips over Key West, then moves into the Gulf straight up the Mississippi River delta into just south of New Orleans Late Tuesday night, a bad case for driving storm surge up the river, and on top of that it then stalls out over New Orleans.

GFDL 18z ... Landfall middle Keys early Sunday afternoon. Then moves into extreme Southwest Florida, rides west coast, exits near Ft Myers, strengthens noticeably west of Tampa, but also starts to move noticeably more westerly. and landfall near Pascagoula, MS.

Recon fixes are a bit wonky still, so based on that, I think the models are very slightly too far west this time around.
