I've read that a landfall in southern NJ would actually have stronger winds here than a direct hit. How about a landfall in NNJ/NYC? Irene-type winds?

It's going to be a Nor'easter and not an actual hurricane, so the maximum winds are usually spread out from the central core of the storm. But this is a new thing we're seeing, we'll see.

Are those 85 to 90 kt winds at the 850 and 900mb level MN Transplant? Wow... And your comparison is showing Sandy will be stronger than Isabel, correct?

Looks like yes on both counts. Not a guarantee that what happens at 850 translates to the surface, but it is certainly interesting. I'll check a few more soundings.

Per the 18Z GFS, its still snowing out here on Saturday. Those who can't come out this way to see the storm in action would still be able to see the results if they came next weekend. That is, if the GFS is correct, of course.

Was wondering when you'd turn up. I gotta find a way to get west of the apps

4.5 Liquid!!!

Interesting. So you're suggesting possible underperform in surface winds? That would be welcome news from the "no power for a week would not be fun" camp. No power for four days ftw!

Not at all. Surface winds will be surface winds. The inversion suggests gusts may not reach the maximum potential of 85-90 kts seen on the sounding, but gusts could still peak out around strong TS/weak Cat 1 speeds.

Well I wasn't expecting 100 mph wind gusts anyway lol. 20% deduction would be 75-80 mph (if that's the correct deduction to surface winds from the 900/850mb level to surface)
