Entertainment: Long-Range GFS

#1 Postby WindRunner » Thu Aug 04, 2005 4:00 pm

http://www.nco.ncep.noaa.gov/pmb/nwprod/analysis/carib/gfs/12/index_ten_l_loop.shtml BROADBAND (or a ton of patience) ONLY

Salt shakers ready?

The GFS is always fun to look at, and I actually have to agree with the majority of its track for soon-to-be Irene. It takes Irene north of the islands and anywhere but to the fishes. The ever-so-reliable 384 hr. GFS shows Irene off the coast of Jacksonville. It sounds like a good path, maybe a little south of my thoughts, but a good path. The wave just coming off the coast of africa is what it develops into a smaller and a little bit weaker Jose (should be depression 72-96hr range). Jose turns north a little further east than Irene, but shadows her at a safe range to the ESE. The model shows a little bit of growth (wind field) by Irene late in the period, and show deeping over the Gulf Stream. Now things get interesting. If I see correctly, Jose gets close enough to the (due) east of Irene to start to dance (Fujiwara or whatever the name is). With Irene in the little bend formed by the GA coast, she slows down and turns right to parallel the coast. Jose slows down as well. This could just be a turn to the NNE by Irene, but it starts to show Jose's isobars melding into Irene's, and Jose practically disappating for no visible reason (other than Irene).

Now the hard-to-predict stuff :lol: : This could drag TS winds from Melbourne to ? (Norfolk?) as she heads up the coast at 384+, especially since it does not show significant weakening due to proximy of FL/GA/SC coast. A track from here for Irene could look like Alex did, scraping Hatteras and providing surf for the NE.

Now, everyone take the lid off of the salt shaker, tip it back, swallow, and comment.

Reversal

#3 Postby jimvb » Thu Aug 04, 2005 4:06 pm

It's a sudden reversal of even GFS runs. Odd ones have been showing a threat to the coast, but now as of late the even ones, such as 12Z, do too. The 12Z sends it out to the Atlantic to fish, but then the Bermuda high moves right, causing a turn of the stormto the west and towards the Carolina coast. And this is the first storm, the one that all along was going to go fish - probably now TD #9. 384 hours on GFS is way out - the similar run on Isabel in 2003 called for it to hit New England. But I will keep an eye on it.

How accurately did the GFS verify with the heat wave and the high over the eastern US this week?

Why would next week be any different?

Hold on, did it or did it not forecast the heat, because my home thermo hit 101.1 today.

thanks...GFS is horribly bad when forecasting Ridges and or heat waves...I think that is CLEARLY evident right now with there model tracks for this system....yesterday they wanted a mid-atlantic path...now along the FL coast...come on...lets me honest...nobody knows and the GFS certainly dosn't...specially right now

This my forecast for future Irene.

Irene will eventually become a hurricane. She may possibly go out to sea and hit bermuda or miss it totally. Also she might hit somewhere between Florida and Massachusetts...

This forecast is valid as 4:30 PM CDT

If you think that was a trip, look at the 18Z GFS. Does basically the same thing with 95L, but takes it into the Del Marva. But, our "Jose" goes through the Caribbean, then turns NW over Western Cuba into the SE GOM. All the while 5 other lows show up in the Atlantic. HEHE. Does show one thing though. As wrong or right as it is, its showing a lot of potential development.

I like that 18Z run. Irene landfalls on Delmarva, runs up coast quickly to ext?, Jose becomes gigantic monster moving into S central gulf by way of cuba, Katrina comes and goes, scraping northern islands, and a future Lee moves off the coast at 384 (8/20) with a 1006, and GFS pressures usually run high. I think 11, almost 12 by 8/20 would be a new record. I'm going to keep up the optimism, though. Smash '33!
