phil882 Posted August 26, 2011 Share Posted August 26, 2011 Major differences between the 18Z GFDL and HWRF- GFDL hits near Morehead city then up to over eastern PA, HWRF way way east, misses Hatteras completely, landfall Block Island. This one is still not set in stone.... I'd be willing to go with the consensus vs. HWRF at this point. Link to comment Share on other sites More sharing options...
Kenny G Posted August 26, 2011 Share Posted August 26, 2011 Can you say a little about the relative performance of the HWRF compared to the globals? My sense is that the HWRF has been all over the place. Does its performance improve closer to the event? Am I correct in remembering that the GFDL pushed Irene through Florida just a couple days ago? Correct me if I'm wrong... not sure if that helps in speaking to consistency. Link to comment Share on other sites More sharing options...
Kicking Up A Storm Posted August 26, 2011 Share Posted August 26, 2011 Newb here wanting to learn: Hasn't the GFDL model led the way with Irene being west for basically the entire time? Didn't everyone laugh at its extreme scenario when all the models were trending east a couple days ago? So with that being said, why does it seem like the major media stations are still going with the GFS, which is one of the furthest east out of all them still, while there are a few - GFDL included - showing it going as far west as passing right over DC? Basically, if the GFDL has been consistent in it's more inland approach, and the GFS has been trending towards the GFDL, correcting itself from the eastward trend (which the GFDL never really had) then why are people still putting a lot of stock in the GFS? I want a better answer than: "The GFS is usually the better model of the two", because surely that's a moot point considering the circumstances here where it seems like the GFDL has been more correct than the GFS. Correct me if I'm entirely wrong in any of this thinking.... Link to comment Share on other sites More sharing options...
phil882 Posted August 26, 2011 Share Posted August 26, 2011 Remnants of invest 98L. They were fully factored into the models. 98L is falling apart as the surface circulation is no longer identifiable... the mass to the west of that feature is more interesting since it seems like its a mid-level low pressure feature that could have some influence of the strength of the ridge.

I think a slightly more Easterly track will begin to show itself late Friday into Saturday. JMO Link to comment Share on other sites More sharing options...

violinist Posted August 26, 2011 Share Posted August 26, 2011 However last night the Euro, shown here, was taking Irene from Moorhead NC up into cent md. It wasn't only the GFDL showing this track. Its rather interesting that two other stations that I watch,continually use the GFS as its model of choice to show Irene's track , without even mentioning the Euro.

Cheeznado Posted August 26, 2011 Share Posted August 26, 2011 I'd be willing to go with the consensus vs. HWRF at this point. I agree in general, this just is keeping the possibility of a slightly more eastern track in the back of my mind.... Link to comment Share on other sites More sharing options...
chris87 Posted August 26, 2011 Share Posted August 26, 2011 I agree in general, this just is keeping the possibility of a slightly more eastern track in the back of my mind.... I'd agree...if the HWRF had shown any consistency in the past 3 days...it was way west when everything went east...now way east when everything went west....

phil882 Posted August 26, 2011 Share Posted August 26, 2011 http://philstropical...lina-coastline/ Updated Track and Thoughts... a little more pressed for time today, but my track is nearly identical to 24 hours ago, maybe just ever so slightly west, intensity down a tad although I still expect the system to intensify in the next 24 hours somewhat. If the forecast looks close to the NHC its because it is, I think they have an excellent forecast as well. Link to comment Share on other sites More sharing options...

Right now its best to go with the globals... they have the best handle on the upper air pattern right now. Link to comment Share on other sites More sharing options...
Amped Posted August 26, 2011 Share Posted August 26, 2011 Here's my call. Add 20MB to that and ignore the time. I've shifted a little, but I'm not buying the EURO. the flow just isn't going to amplify and break apart the Quebec PV fast enough to allow for a track into Burlington. At least I copied from a known phycally possible August storm track. Link to comment Share on other sites More sharing options...
Cheeznado Posted August 26, 2011 Share Posted August 26, 2011 RGEM is similar to the NAM through 48- over or a hair east of Hatteras. I am beginning to think NHC is too slow and a bit too far west. My call right now is central or eastern LI, I am tending to agree that the Euro was not all that good, will be interesting to see what it does tonight.

Scott747 Posted August 26, 2011 Author Share Posted August 26, 2011 NJ seems to be under the target of Irene with the 00z models 0z model runs have just recently started. NHC track is already up to date with 0z guidance from 18z runs. Link to comment Share on other sites More sharing options...

gracetoyou Posted August 26, 2011 Share Posted August 26, 2011 Wait... You're honestly taking the RGEM and NAM over the Euro? If you look at the RGEM today, it's had a pretty large fluctuation; therefore, I wouldn't put too much stock into it right now. Link to comment Share on other sites More sharing options...
Thunder Road Posted August 26, 2011 Share Posted August 26, 2011 Not that my opinion holds any validity but I also feel and central Suffolk or slightly East of there is the bullseye.. Maybe I'm wrong but the NAM and RGEM are mesoscale models used to solve truly mesoscale problems live convection, for instance. The exact track of Irene is a synoptics problem, not a mesoscale problem. That's why I would trust the Euro over the NAM and RGEM, or even the HWRF and GFDL at this point, since those also are not synoptic models (in a rough sense anyway) Link to comment Share on other sites More sharing options...
mike2010 Posted August 26, 2011 Share Posted August 26, 2011 GFS is east too. If ECMWF is east as well, NHC will most likely shift back east a tad at 2 or 5am. Link to comment Share on other sites More sharing options...
chrisNJ Posted August 26, 2011 Share Posted August 26, 2011 GFS is same as 18z basically..just 6 hrs faster and stronger GFS is east too. If ECMWF is east as well, NHC will most likely shift back east a tad at 2 or 5am. Link to comment Share on other sites More sharing options...
SnowGoose69 Posted August 26, 2011 Share Posted August 26, 2011 GFS is east too. If ECMWF is east as well, NHC will most likely shift back east a tad at 2 or 5am. I had been saying for some time the track into NYC and the Hudson Valley of NY was not happening. It was either going to take a more Gloria or Bob type track where it has some NNE or NE motion to it after it hits NC or it would trend hard west and go straight into NC. Given the latter is no longer likely to happen I'll go with an Outer Banks or Pamlico sound crosser and then landfall in central Suffolk county in NY. The end result will be minimal damage for the 5 boroughs and possibly most of Nassau county though there may be severe flooding in some locations due to the timing of high tide.

Roger Smith Posted August 26, 2011 Share Posted August 26, 2011 Subjective prediction, after studying the guidance and the recent history ... the recent northward turn looks to be progressive and there are few strong indicators of any other track but the one shown earlier by "Mad Cheese" perhaps shifted a bit north in New England. Overnight and Friday, Irene may intensify to cat-4 but then lose some strength late Friday approaching Cape Hatteras, back to cat-3 or strong cat-2 as it brushes Hatteras and moves NNE about 30-50 miles east of Delmarva then 100 miles east of NJ. Second (or eventual) landfall central Long Island strong cat-1 or weak cat-2 heading NE towards Groton CT, Providence RI, Lowell MA and up the NH-ME coastal strip crossing into NB just inland as TS and northeast into Gulf of St Lawrence. I hope this is correct because the only major damage from such a path would be in eastern Long Island, Rhode Island and southeast MA, and also rainfall potential might be less than catastrophic for inland northeast. No storm surge except Narraganset Bay, southeast MA and islands, and some parts of east Hamptons. We shall see ... but this would be good news for NYC and about 50 million people.
