GFS/CMC diverge from Euro regarding the trough beginning Friday am.  You can see 500mb on Thursday morning pretty much identical at 500mb.  WAR going up, departing ULL, positioning of the trough in the west, and the the vorticity associated with said trough etc.






The main difference begins about 24hrs later by Friday morning.  Take notice at the differences just off the west coast of Canada and the NW CONUS.  Euro simply has a weak upper level low feature which leads to a series of weak LP strung out leading to an extremely progressive flow, west to east.  There is nothing to drive the energy into the plains to deepen the trough as it propagates eastward.  So by 00z Sunday morning the flat progressive nature of the trough takes Matthew ENE trajectory; well S and E of our area.





GFS on the other hand...as you can see has a stronger upper level feature just off the western Canadian coast leading to one consolidated LP that raises heights out ahead of it.  Not a ton, but raises heights none the less so instead of one long flate western flank to the trough it allows the energy to dig a little as it propagates across the rockies into the plains.  Result is a sharper trough, although still not overly impressive, but sharp/deep enough to steer Matthew in a more NNE trajectory with much more impact to our area.  





As you can see the CMC is in same camp as GFS regarding the features I just outlined in the west.  The energy that I have circled in the first set of images is coming onshore today an tomorrow.  It wont be long until its nailed down for sure.  A blend between the CMC (strongest with the trough, and the Euro (weakest with the trough) gives you what the 6z GFS is showing which means as of now I expect impacts in the form of windy and rainy conditions.  The next 24-36hrs should zero us in whether its dangerously windy and rainy vs just ehh.

I also noticed the GFS 06z sped up a bit, I wonder if the trough is being under modeled on all the models, though they are there, I guess we will not know yet for at least another day. Dangerous or just ehh, lol sroc ehh, I can picture u saying that. Great analysis as always, we are waiting to see what the final out come might be. The TS force wind probabilities are slowly pushing nearly into the area, hey u gotta start somewhere.

Pretty good consensus on moderate to dangerous impacts on the area, this is just so back and forth every single day. Amazing, poor Haiti I can only imagine what it must be like at this moment.

Larry Cosgrove is pretty convinced of the CMC/GFS/UKMET track up the coast with significant impacts likely. I have def seen him wrong before, but he has been consistent with this idea for several days now. JB on the other hand buying the east soln of the euro. with minimal impacts.

LC:
It now appears that most of the Eastern Seaboard of the USA will be affected by Major Hurricane Matthew. now battering Haiti. Matthew will exit the Windward Passage tomorrow and bend to the northwest. Over very warm waters in and about the Bahamas, the powerful storm may again attain Category 5 status. The track scenario shows a close scrape 100 miles east of the FL Atlantic Coast, then a turn inland over the Carolinas (Category 4 strength) before rolling along and to the left of the coastline with abundant wind and rain. It is entirely possible that many communities from eastern Virginia into New York and New England could see a period of damaging winds as the system starts to transition to cold-core type of character.
Much colder air will follow early next week across the Midwest and Northeast.

Oh good grief, another one to track towards the US, storms from there likely get pushed out though. Matthew is gone by then? Wow that was fast. Euro has been speeding up though each run.

^^ Great Post - Euro coming around to GFS idea - I can't believe on twitter and in forums that folks are saying the euro nailed this - I very much disagree





ANd I have to say I watched Channels 4 and 5 this morning and they both showed tracks up the coast nothing into NC and then gong due east - THAT in itself is....................

GEFS saying come to Pappa



NOW 12Z - OH BOY

Scott,
Even JB's son is in somewhat disagreement from what he communicated with a member from teh USA board yesterday who is friends with him. JB has been euro riding all along and will go down with the ship - he keeps barking how teh Euro is right - I love JB but give it man - it has corrected 1000 miles - it EURO has been alright to good within 1-5 days but after that it has been terrible.

Bahamas are going to get whacked big time if model depiction holds - when was teh last time a Hcane of this magnitude hit them?

Yeah Mugs, I know enough now to disagree with the best if I feel they are wrong. JB was one of the last to abandon the GOM idea as well.

It is going to be interesting to see the Google earth images of western Haitian peninsula before and after. The geography is likely changing as we speak.
