Only if you take snow map verbatim Alex. Remember its an ensemble in. Not the best resolution. Every single member has the MSLP between 970-988mb. There are a few in the 960's. Tranfer comes off the Delmarva and passes south of LI

I wouldn't say that. Last night two NAM runs had LI going over to snow. If the secondary sets up shop just S and E of LI and bombs out, it could definitely pull in enough cold air, especially at the upper levels to produce snow over Long Island.

That said I do remember well a couple storms earlier this year where LI cashed in and us folks further west got a little bit of the shaft. Soooo, sometimes things even out. lol. Anyway, I hear someone out there has a big exam to study for, so if it has to miss you -- maybe this isn't the worst one to have miss. Wink

Here you go Jman:

EURO 900 hPa sustained wind speeds, in knots, for the windiest frame. Since this is 900 hPa and on the northwestern side where we get our wind events to mix down to the surface, I would say 90% of this mixes down, maybe close to 100% AT TIMES:



Keep in mind, this has a lot of westward correction to undergo at the lower levels, so in theory, these should go up, though by how much, I cannot say.

Snow map please.



This is the second time the euro has drawn a snow map, the first time was about four days ago, with the rain snow line for this storm, that looks identical to the February 25 26th 2010 storm. Identical of course if you took the snow amounts and times them by three. I know you said the dynamics are not even close between the two and I believe you, but that is one part of this threat that I still find interesting.

Bernie RAIN-O Shocked

"The focus for snow Fri is not with the sfc low,it's with the placement/strength of the upper low. With the exception of the higher terrain in NY/PA this will be mostly rain. How, just N of the upper low there will be a band of heavy,wet snow.ECMWF 500 mb fri am."

I don't disagree with this. If you recall, somebody had asked me earlier about the coastal plain, and I felt that the ceiling ratio of snow versus rain was 50-50. 50% rain on the front end that goes to the final 50% of precipitation in the form of snow on the back end. I also said that the overall QPF would be much more than 1", with in excess of 2" probable. Given the max 50-50 ratio of rain versus snow, you just saw the results on the EURO. So while it may technically be "mostly rain" by amounts, that doesn't mean that a significant snowfall should be written off, ESPECIALLY NORTH OF I-78. Also, it is the H5 energy that holds the key for the snow part of it, but the placement, intensity, and timing of the secondary development will help dictate how soon the change can occur in relation to the positioning of the H5 energy. The stronger and earlier that secondary develops, the faster the lower levels will cool in advance of the brunt mid-level dynamics, thus allowing more QPF to fall as snow and start the pre-accumulation processes earlier (cooling the column at the lower levels, cooling the ground, etc.).

I think we may see another big NAM run here. H5 looks like 06z again. We'll see.

Too much interaction too soon on this run. Dang. Still a ton of volatility to this system, though, and it could be an over correction to start swinging the other way again. Gonna still see how this run plays out though.

Late to the party...

This seems to come down to the primary low. If this low cuts north it will warm our mid-levels so by the time the secondary takes over we have to wait for cold air to spread into the mid and lower levels. Whereas, a primary that does not cut will leave many people seeing an all snow or brief rain to all snow event.
