18z gfdl 935, likely overdone... landfall around acy...also after sandy moves past hse and starts her bend back gfdl and hwrf which takes the storm into LI take sandy to a cat 2

Yet another 'southern' outlier creeps up North. Still baffled by the NHC's southerly track from their last update... I wish for it up here in NW Jerz (former Media, PA earlier this week --- just moved), but not believing it at all...

The NHC isn't really forecasting a specific landfall location, just a range of possible locations (i.e., the cone). If you turn the track on then it looks like it makes landfall between Lewes and Cape May, but that track is just a straight line between the last offshore position and the first onshore position. It could be that it actually comes onshore north of ACY and then curves down (WSW) to Baltimore to reach the Tuesday 2 PM position.

As the disco says, pinpointing the actual landfall location isn't very important right now since it's likely to change anyway. Instead, the purpose of the forecast is to prepare interests inside the cone (between E LI and S VA).

So pretty much according to the models the timeline for initial landfall is late monday night into Tuesday morning?

With the center... Conditions will detoritoate throughout Monday. Possibly raining here with some type of PRE event by Sunday.

I've seen the GFDL and HWRF consistently blow up Sandy into a Cat 2 equivalent between 12z and 18z Monday. Due to the switch from tropical to ET perhaps?

While I think those winds will be overdone, and I know nobody sees Cat 2 winds anywhere on land, it does worry me (and it hasn't really been discussed much) that Sandy will be strengthening right up to landfall, something you don't usually see up here. We all know from Josh how much more powerful a strengthening system is than a weakening one. (Even if that doesn't apply verbatim because he's referring to tight pressure gradients on warm-core systems, the idea remains the same.)

GFS ....very similar to NAM....

still time for things to adjust but...yeah...right now draw a line halfway up the Jersey shore between Toms River and Sandy Hook....and you won't likely be far off

Yup, with I'd say equal (but lesser) chances of hitting Atlantic City and Montauk, NY directly.

We'll see what the models say tomorrow. HA!
