ive already thrown this run out

The gfs will keep us snow. I'll stick with the euro for now, I don't think the nam can get much more wrapped up than that and even then we barely get to zero at 850 but suspect that above 850 there would be a warm layer so we can hope for a little low that is less wrapped. The trouble is, there is enough space for such a solution and it has lots of sref support. Thankfully, we have the euro and its ensembles to hug.

It will "probably" bail based on what exactly. I dont think anyone knows what the euro will "probably" do tonight.

it was a "joke" though it's sort of an outlier in its own right even though its the euro

If it could bomb a little earlier, could be a big storm here...

Funny, I thought the same thing. Not hours or hundreds of miles either. Just about 50-75 miles more south.

I'm going to the weenie security blanket. Neither player is in the US right now, you can see that on sat. According to models they will be by tomorrow afternoon. Tomorrow's (not tonight) 0z run is the one I'm going with, good or bad.

it's hard not to like the high resolution of the nam but at the same time it's hard not to distrust it at the end of its cycle. at least we're within its range now!

Could you or someone elaborate on that. And could someone post the link to the site where you can get those snowfall amount maps from prior storms?

There's a ton of info here, including snowfall maps, H5 maps, surface, radar images, etc.

Then there are the NESIS maps

I remember that storm here in the DC area. Forecast was calling for 6-10". I think it was a situation where we basically had an occluded front go through, precip ahead of it then essentially dry-slotted. Ended up with a burst of snow, some sleet, then it got pretty cold in the days afterward. And we only ended up with about 3" or so. Real disappointment.

Out to 48 on the GFS theres some slight differences with hieghts in the lakes and MA (compared to 12Z), as well as s/w placement, that seems like it would be a bit more amped as an end result. Perhaps its starting to come around. Then again, it is the 18Z run.

Really thinking in the end this will be a one barrel LP from Hatteras on North.

Looking at the GFS 18z at 48, 500, if that's all I had to go on, I'd think a storm straight through the OV. But since I've seen many results beyond that that don't do that, I guess I'm biased to think it won't.

Can you determine the path of a storm by the curvature of, in this case, the 1020?
