Re: ATL: MATTHEW - Models
My curiousity is what is driving some of the models east and out to sea? I must just not be seeing what in those models is driving it out.

Other than the Euro, the GFS is probably the most accurate at this range and has a hit near Norfolk VA, which is not really out to sea.

Re: ATL: MATTHEW - Models
Looking over the more detailed surface, 850mb, and 500mb model data and forecast from the CONUS perspective on NCEP and I'm just not seeing the trough formation or rationale for weakening ridge strength, or reasonable impact to the directional flow that would seem to cause a generally westward momentum to simply "stop". Perhaps the storm deepening itself along with weaker 500mb heights as a result of reaching the western periphery of the strongest part of the high to the north, but I see little to suggest that low level bridging doesn't remain from east of the Bahamas westward toward Central Mexico. If that were at all plausible than I'd go so far to think that a turn toward W. Haiti would seem no more likely than a track toward W. Cuba and into the Gulf.

wouldn't it be the storm about to come ashore in the Pacific Northwest that would influence it to turn north? or would that be too late

Euro with some weakening between 24 and 48 hours but position is nearly identical to the 12Z GFS.

Re: ATL: MATTHEW - Models
12Z EC is much stronger through the next 24 hours than the 12Z yesterday. Perhaps the shear is actually not as bad as once thought.
EDIT: and of course then it weakens the TC right after I say this.

Re: ATL: MATTHEW - Models
12z so far seems to look slightly more SW going west instead of the slightly more north that all the other ones are showing between tomorrow and 72hr

Re: ATL: MATTHEW - Models
Between 48 and 72 hours very slow turn and now is slower than the GFS at the 72 hour mark and slower than the 00Z Euro.

Re: ATL: MATTHEW - Models
AND.... something at right about this time has thus far caused the storm to turn poleward yet all that I can see is that the 594 high south of Texas seems to weaken and so does the ridge to the north of Matthew right at this time; yet the only low in play at the moment which is the SE Conus cut-off low, appears to weaken and shift northward? I've heard of pumping up the ridge, but not pumping down the ridge.

Re: ATL: MATTHEW - Models
Today's 12Z Euro a bit further east than yesterday's (though identical through 48 hr with the extent/timing of SW dip). Lower heights over SE US which continues the trend from yesterday's runs.

Re: ATL: MATTHEW - Models
The 12Z Euro hour 72 is pretty much right in line with the interpolation of the 0Z Euro between hours 72 and 96 except maybe a tad faster. Also, it is clearly east (~40 miles) of the Euro hour 96 from 12Z yesterday.
