I'm not really focusing on its track, I'm more interested in the strenght and position of the upper air features in question, because that is ultimatly what is going to drive the cyclone.

The combination of the upper air westerlies and where the strength and position of the upper air features is what working against the storm giving our any direct hit and making more likely a fish storm.

my point and click

Saturday: A chance of showers and thunderstorms. Mostly cloudy, with a high near 80. Chance of precipitation is 40%.

Saturday Night: Rain and thunderstorms. Some of the storms could produce heavy rainfall. Low around 71. Chance of precipitation is 80%.

Sunday: Tropical storm conditions possible. Rain and possibly a thunderstorm. Some of the storms could produce heavy rainfall. High near 78. Chance of precipitation is 80%.

Sunday Night: Rain likely and possibly a thunderstorm. Some of the storms could produce heavy rainfall. Mostly cloudy and very windy, with a low around 67. Chance of precipitation is 70%.

I didn't say the developments that the NAM were showing were positive, I was simply stating why I was even considering anything the NAM has for a tropical system.

Keep in mind that even if this misses east by a good bit, the rain will spread quite far to the NW. Even if the winds aren't ridiculous, the impact from 6 or more inches of rain is quite severe too. The threat is greatest along the coast but even the last 2 GFS runs spread the heavy rain shield well into NJ/NY.

I see nothing but an eastward trend and days ago it was suppose strike FL, then SC and NC. LI last night, now brushing the cape, with this eastward trending not stopping I won't be surprise if this even goes further east than Earl and Edward and go SE of LI probably 300 to 400 miles and go completely out to sea. I am talking about probably similar track to Bill in 2009 with just rough seasons and beach erosion with most of the rain staying off shore as well.

:huh:

Models are in great agreement for this time length and haven't lurched that much in the last 2 days. 50-100 miles isn't a huge change at this far out. There's also no reason why this will bend way east like a Bill or Earl unless a trough/kicker comes in way stronger than modeled now.

I've seen some of your posts over the past several days and all I can say is :weenie:

If the models suddenly shift west, you will jump on that bandwagon as well. Why? Because you may be able to read a model, in general terms, but you have no clue as to how the model arrived at its respective solution.

Read more, post less, I'm guilty of it myself at times, but I've learned alot just by reading what red taggers post.

The wording of the forecast posted for SW Suffolk County on Long Island is curious, as posted on wunderground.

After mentioning that 'tropical storm conditions are possible' for both Saturday night and Sunday, it has this for Sunday night:

"Rain likely with a chance of thunderstorms. Hurricane force winds with lows in the upper 60s. Chance of rain 70 percent."

update: The new noon forecast changed the wording for Sunday night to 'tropical storm conditions are possible'

Through hr 27, Irene looks quite a bit west, I'm likeing the looks of this run early on

The differences over SE Canada with regards to the amplification of the trough are big, much less amplified this run. Stil too early to tell what it means.

Can't you just wait till we have an idea of where the run is actually going, then post a coherent, condensed discussion on it? These hour-to-hour posts can be misleading I find (the NAM's "west west west" trend didn't turn out so well).

The differences early on this run are HUGE and if you don't believe me, they are saying the same thing on the main forum.

well.. the ridging in the atlantic seems to be built back westward a bit and the trough across Canada is not quite as far dug so south so the overall wind field of westerlies across the northeast became a bit lighter... the speed of the system is every so slightly slower and looks a tad west so far.

Looks to me like it jogs to the west a little at 78 hours then back to the east at 84. Unless the trough to the west sharpens quickly and pulls this due northward I think this is an eastern New Englander.

yea.. it's subtleties all around that will make the difference... it definitely seemed like the trof over Canada intially had less influence because I could see the 500 mb wind pattern was probably a good 10-20 knots lighter for a period of time, so it might have been still more steered by the weakness in the mid level ridge, but I agree, the wavelength of the trof is fairly open so it predominantly has a SW flow as opposed to a southerly flow.. it'll be interesting what happens with the ridge over the Atlantic though.. I did the see the height fields build back rather significantly over the previous run.. but again.. this is one model comparison.. there are so many other models to consider.. it really is going to be impossible to forecast until pretty much game time.. problem is that 50-100 miles makes a world of difference for someone...
