Haha oh man I happily forgot Big Joe even existed. I remember 16 year old me tracking hurricanes and I thought that dude was the GOAT of forecasting tropical systems....ohh how much I've learned. :rolleyes:

But anyways, when should I start boarding up in Hampton?

Wow. That's what, 3-6 members out of 51 that track offshore up here?

Inland runner?

Still skeptical on the more W track.  The trough that evolves over the ern U.S. is not digging and is positively tilted.  That's not how you typically bring a TC to SNE.  Basically it is just riding a channel in the mean flow, not drawn in by backing flow.  One thing I have noticed empirically over time, is that these things tend to recurve out sharper than any model forecast in a synoptic set up like this.  You have to find a good reason why it will *not* recurve out sharper than forecast.

Here's the pattern that brought Bob up.  It was focused, digging s/w trof that gave SNE decent +RA/+TSRA only 24 hr after Bob departed.  And the next image is the 00z GFS for 96 hr.  It's not the same.  In Bob's case, you had a dumbbelling effect.

GFS now kisses FL too. We may have to watch that trend. If it does scrape FL and then head into Land near SC/NC...not sure how much is left once she gets here.

I think it’s going to trend like Matthew and stay off shore here, but will be close. Looks like some shear my interact with it near FL

Agreed,  tough to get a full blown TC with a positive tilt 5H
