Isn't that a good bit different from 0z? I haven't seen any maps and it's hard to tell by the discussion

its north but we're talking pretty small run to run shifts on both it and the gfs at this pt.

Yeah, I read about this big n shift on few comments in the new england thread and thought, gee, maybe we getr lucky, then I look at the model and see only very minor differences. You expect small wobbles from run to run. The euro has been pretty consistent and is pretty similar to the 12 GFS.

Some wishcasting going on over there right now. They think the Euro represents a massive change from the GFS and the 00Z run.

I'm fairly sure the entire md portion of the bay is pretty safe. It won't even be as bad as a noreaster that stays offshore. With virtually no s-se component there is no mechanism to fill the tank so to speak. Even with a good dose of e-ne before the turn nw would at the worst stack up the western shore a foot or so. Probably not even 2'.

Latest marine forecast clearly shows the highest winds from the nw. Md bay can handle virtually unlimited nw winds with few flooding issues.

Thanks a lot for your reply, Bob. It does look like we're lucking out.

Most of LWX CWA is in the 70 kts... but there is an area of 80+ kts for N VA/DC/ toward S MD (south of BWI by a small tad) -- this again is for 00z TUE... or Monday evening into overnight

Wow...that's really impressive. As other have said tho - I bet a lot won't get mixed down. Still seems good for 60-70mph gusts for sure.

From Mike

I've been working on this yesterday and today, and I'm pleased to announce

the release of a temporary sector just for Sandy as it makes landfall in

the northeast. It's a minimal selection of products that are zoomed in

slightly and a bit easier to read than some of the other images that we

offer. It's running for both the NAM and GFS, and both models offer a

Total Precip Accumulation product so we can more easily see the rainfall

impact. This sector will be removed once its usefulness has expired.

Pretty neat.

It's hard to see it because of the flood watch, but State College has issued a High Wind Watch.

Surprised that the text says "up to 60" or "up to 65" - Might be a good idea to point out the potential for higher gusts in a few spots. The public has a tendency to be dumb...but 60mph is nothing to sneeze at.

Its in a way a bit ridiculous, the average gusts will be 55-65 and around Philly there will definitely be gusts 70+ for a few hours I believe judging my the GFS and Euro so close to the surface

Question for the model pros. I've simply avoided the NAM and haven't even looked at many of the panel nor have I taken its solutions seriously. Is now the time to add it to the bag or is it just not good with tropical / ex-tropical cyclones?

I'd certainly give more weight to the gfs and euro but would look at it.
