12z GFS Harvey makes landfall near CC around 84 hrs... stalls and sits around in SE TX... then reappears in the GOM at 162 near HOU... then moves back NE into W LA and slowly moves NE before dissipating.  Irma develops around Day 6... but besides brushing the East Coast with huge waves, it curves out to sea harmlessly

Ukie likes north of Gfs latest run

12z CMC is prob 6 hrs slower and slightly farther south in its landfall than the 12z GFS is at 84 hrs.  12z CMC also pulls the SE trick that the 12z GFS does, but gets Harvey back over water at 150 and 156 before making landfall again in C LA at 162 with NO in the eastern quad... remnants then move NE and are in S IL/W KY at 192 and Harvey kind of dies out around there.

12z CMC doesn't do much, if there is anything at all this run, with the Bahamas tropical wave... no real great SLP development

18Z GFS now looks more realistic on strength then some of its previous runs. Now has a 990mb Cane striking Texas, stalling and then retrograding back into the northern gulf.  GFS and the CMC are now in fairly good agreement on the initial strike and the retrograde but the CMC is quicker on drawing it northward once it gets back into the gulf.

That's the 18z..finally got 0z to post. Agree about Texas .Some of the hourly Stamps on a few models are at 144 to 168 and still hanging around the Texas coast.

Much more spread on the 00z, most if not just about all are still in Texas it is just a matter of where in Texas. Have to see what the next run looks like to see if they begin to tighten up a bit again.

They'll "waffle" and open/close the spread for the next 24-30 hours.  The consensus is Texas and it makes sense given the steering flow and book end highs over Florida and the Four Corners region.  The track you're seeing today is pretty amazing considering we are several days away from landfall.

Seriously considering a chase for Harvey.  This could be a once-in-a-lifetime event for portions of the US and could eclipse Allison in 2000 for Houston.  GFS OP max is 48", ENS mean is 12" - 25" of rain in the same area.  There could be national impacts on US gasoline prices and airline ticket prices as many of the major trans-mix, jetfuel and gasoline pipelines pass through or originate in Houston and then travel across eastern Texas.  This is the kind of setup that really gets my heart going.  Oh to be a fly on the wall at HGX and CRP WFO right now.

I am honestly as nervous and excited as if it was going to affect my area. But considering what the scope of this could be and the impacts it could have nationally I think every weather enthusiast/meteorologist is feeling the same way regardless of where they live.
