It's gon be a snow flyin, little boys cryin, forky spyin, Kev sanctifyin, DT denyin, weenie pryin, Pete electrifyin, Ginx stupefyin, Ray obsessifyin, Will memorizing, Jerry cialisyin, Mike petrifyin, Tubes spinifyin, Tip vectorizin good time!

LOL, I see you with a doo rag and a lot of bling. I do think it gets good around these parts before long.

I was in Boston all day. Car thermometer which is pretty accurate got to 42F but I was not checking for long stretches.

Looks like I topped at 37 IMBY. No appreciable snow melt today, maybe lost an inch from melt and compacting.

I'm kind of counting on some clouds in my area to keep damage moderate not major to the snow pack. SW exposures are a given for snow loss so there will be some good loss in places but I am pretty confident we do some rebuilding after the weekend.

I think tomorrow is my day to get in a noon date at Berkshire east for the first "spring conditions" of 2011.

Do you think we stay in a gradient pattern with a -PNA/-EPO leading to SW flow events, or can we get into the snows down here with some bigger coastals after 3/1 as the PNA starts to neutralize?

The later, really liking the NAO state change in March and would expect a more neutral PNA, if you look back at Dec we are probably in the period Jerry referred to, of course sensible weather is different but what we do have in our favor is extreme cold nearby to be tapped, Climo for cutoffs in March, and enough of a Nina ridge to really create some volatility.

Not really either way for the PNA, though doesn't look very promising, without much help from convective patterns in the Pacific.

BUT if we do see the MJO wave become more coherent in the west Pacific later this month, could see a rise in the PNA by early March.

While maintaining a -EPO / neutral to -NAO and VERY cold airmass in Canada ... watch out. HECS threat right there.

29/22, certainly seems weird for it to be so balmy out after so many nights below zero so far this Winter. Hey Ginx, what was the date you were looking for a big storm back a few months ago? Wasn't it around now? GN.

NO HM was looking at next week. I am looking at March 19-22 but am not saying another word until after. I really like the first week of March new moon 4th or so and thats two weeks after this happened. Teleconnection?

The pattern is so tedious...the GFS allows a front running wave ahead of the PV on this run to give us a nice little snow event and then suppresses wave #2. I still doubt the idea of two waves.

We see this a lot and it usually doesn't happen (though its happened twice this winter, so maybe its a seasonal trend). It should be interesting to watch over the next 48 hours. I already see a lot of people over analyzing the models in other subforums...I think everyone has caught the "disease" of quiet weather over the past 7-10 days and a 100+ hour threat seems like a 3 day threat to everyone. I will bite on the very suppressed PV idea only until I see it consistently for the next several runs. The long wave pattern is really against it on the PAC side so there's definitely a battle going on.

I still doubt it, but I think that we can now consider it a realistic possibility, as opposed to simply laughing it off.

yea I was just posting what it showed. What do you think of the wind ? not crazy high but that a good deal of CAA with some cold wind chills in store, banana hammocks, frisbee cancel and oh nice inversion on the torch.

At least it looks less likely to be a rainer....I think that is the last thing that we would want to see after this impending torch.

Models are almost certainly going to struggle with this pv feature. This is classic territory for the models to really have trouble. That thing coming down from N Canada and then at the same time some potent wave in a -PNA pattern....that is a total clash on the models. I wouldn't be surprised to see models trend one way and then violently trend another direction. Its the nature of the setup.

I could be wrong and they have it well handled, but I don't feel right about all this stuff with 2 waves, vs 1 wave and one being north or suppressed. It just doesn't look right to me from run to run. We'll see in the next 2-3 days though. Don't forget the Feb 1-2 event where the 2nd wave trended much colder until about 48h out and then it went much warmer/north at the last second.

94 ish I know it is used too much, the 2 wave scenario further north riding the thermocline with just enough PV influence does make some sense.

I too am definitely not biting on full blown suppression yet either and that vortex feature will most certainly be difficult for the guidance to handle as well as any embedded S/W's embedded within it. I would not be surprised to see the Euro completely change just as the GFS starts hitting on the Euro idea. SREF may be a bit out of range with that vortex--but they definitely would be far less suppressed and a few would develop a large cyclone as the wave ejects from the inter mountain W. The only other "big" question is the strength/organization of the western trough before ejecting. One thing is for sure--the low level thermal fields are pretty impressive and a lot can happen with small height field config changes,.
