You noted that the northern shortwave did not look different from the initialization, any news on that?

It still looks similar. The separation in guidance doesn't begin to occur until 18-30hrs from the 12z initialization in regards to a strong shortwave coming through the Dakotas. Basically we won't have an idea until tonight at the earliest. I am surprised at HPC's jump to discard the GFS. Especially with the NAM and some globals trending in it's direction for a few cycles now. I wouldn't run with the GFS but I certainly wouldn't throw it in the trash.

I know they dont react like this, but it almost sounds like they're upset because they got burned so badly when the euro showed close to the same solution a few days ago. Maybe theyre thinking of the last storm, when this happened in reverse lol. Regardless, I doubt that solution verifies either.... but the way OTS solutions are also a bit suspect.

I would've understood if the GFS had such issues that it wasn't worth looking at. That's fine. But then they go on to state the 00z ECMWF had similar issues, and then they blend it into their forecast? The reasoning doesn't make much sense to me, but I guess for the sole sake of continuity they used that idea.

No chance.

I would not say no chance, very minimal perhaps. One of the things is each office looks at the HPC suggestions and then makes their own tweaks. One office may like a model, the other not. With that being said, watches for the east end perhaps, or New England could happen. Mt. Holly probably would just mention it in their hwo again, and say it is too early.

Watches could be issued for Suffolk, New London, Middlesex (CT), and maybe that's it for now.

Earthlight, i also have to ask you this. I noticed they are flying reconnaissance planes somewhere along the east coast? When would this data be inputted within the models? 00z, or 12z tomorrow? Also, judging by the trends on the radar so far, is it supporting one model over another yet? I know it is difficult, as they go astray from hours 18-30, however, anything that would be considered a red flag in either direction, phase or no phase?

I want this model crap over with by 18z and not wanting to look at a model at all tomorrow. If 18z GFS goes way east of 12z then it's game over for I-95 west? I'd think so at this point.

Talk about a cluster**** of events my god. I for one was never really "hyping" this event but i kinda got my hopes up at the gfs and all the baby models. laugh.gif

I see you are from Union county, as your status notes Elizabeth. I always wondered why union was part of uptons territory and middlesex holly. It always makes for an interesting forecast. Once a town just north of me had 2-4 inches predicted by upton, and my town, in holly's zone was double that.

No real reason, other than the DOC had to draw the lines somewhere.

Just a thought here: The thunderstorms breaking out in Texas and OK was a bit of a surprise to me. I've been pretty impressed with that southern stream SW so far, particularly since I didn't expect that much convection associated with it.

That southern stream certainly is juicy. I mean, it was even as it hit Cali-- very el nino like.

I noticed that as well. I am not that familiar with the dynamics of severe weather. Just glancing at it, i thought tornado warnings might have to be issued.
