Day 7 850 map of N America

so does that real cold air ever make it down here or not?

if it does, it won't until after we get a brief warm-up it seems to me

I posted it in the NE subforum, but not sure if anyone already mentioned it as I didn't read pages from earlier this afternoon.....this looks eerily similar to March 1960 in just about every aspect....NAO block, AK block, and CONUS trough are almost identical. The only difference was it was just a shade north of the trough position in 1960 so its overall a slightly further north development. But I thought the comparison was pretty fascinating.

Obviously everything would have to break perfect to get it to that storm's magnitude, but its a good sign that a storm has a good chance to occur.

Will, didn't Jerry mention that the other day as well?

He might have, he was mentioning Dec '60 before, but he might have said March too.

Obviously nobody should expect a storm of that magnitude right now, so its probably dangerous to even mention it because some will take that as a forecast....but it shows that this type of pattern can produce a good storm. Its not 100% ideal pattern because there isn't much of a ridge out west for it....but in Mar '60 there wasn't either.

you're right, it was 12/60 come to think of it

Will, do you have any maps from that storm? I can't find much online except hyperbole about lobster boats being overturned and NYC tourists being stranded.

If you have the Kocin 2 volumes, its on page 387...if not, I think there is a snowfall map of it on the NESIS site. The upper air maps are hard to come by from then, though plymouth state weather can probably do the reanalysis.

If someone doesn't post it in the next 10-15 min, I can do it, but just trying to finish something up here.

It was kind of a hybrid Miller B storm much like is currently being modeled. It was a solid 8-12" storm for DCA/BWI areas and then it destroyed SNE later on.

I was looking at that storm in the KU book the other day because it struck me as similar but would not mention it because of what you said.

Euro site just updated

looks like all the cold is on our side of the Pole

the cold mass is slowly moving SE by Day 10 fwiw

N Hemisphere: http://www.ecmwf.int...s!2011010800!!/

N America: http://www.ecmwf.int...s!2011010800!!/

EDIT: I see a Ridge starting to show up SW of Greenland by Day 10

Maybe the start of the next round of a -NAO

Yeah the cold is going to get back in behind that monster cuter low but that is an ugly torch with the wave on the Arctic front forming too far north. Nice -NAO building back in at Day 10 with arctic air coming into the picture, but we need the arctic front to track further south to avoid this mess.

Euro has a nice trough over Japan on Day 10 so the trough should come back in over the east coast iow, that blob of cold in Canada should make it our way, but not to that magnitude of course
