Even without a mid level low closing off it looks like you guys still get an impressive thump of warm advection snows. If the NAM is right there's definitely a good bit of lift practically to BTV.

Hey Ryan (or anyone else for that matter),

I've been working 15 hour days trying to get work done before finals. What's it looking like for my home location in NW CT at the 1k foot mark? Tell my parents to get ready for some snow or no? Thanks, sorry I've been cooked with school.

I guess if you can't find a reason for this to go SE, maybe it won't this time, lol. You've always got a reason for a storm to go further east... c'mon messenger, don't let us down!

There's no boundary to ride...the one that may exist is inland. Temps are going to be in the mid 50s over EMA/SEMA Wednesday. We'll see how it goes in the other runs....even if this was going to nail me I'd take no interest until 12z runs Wednesday because I think we will continue to see the storm tail in as the models adjust for vm strength

I mean, I can defintely see how it could go nuts for a few hours in some areas. The NW trend needs to stop. SREFs at least went southeast, but the euro later on will probably be more telling.

Greens get hammertime thumpin' goodness, Pete and MPM probably a little uneased at that run, and for me and the south coast peeps well. LOL

1. Yes, it needs to stop.

2. Even so, I might still pick up a couple inches once it flips which is a heck of a lot better than the whiff out to sea that was expected earlier yesterday.

53.3/53

The front is really getting poorly defined I think. Places that have gone northerly are still hanging in the 50's. Push of cold air is very weak now and it is extremely shallow.

Even here is it is a hair over 0C 850 when the better precip arrives at 0Z on the NAM, but I think we would flip fast. Places like ALB may waste precious qpf in a few more hours of rain so can't assume they are getting any major amount of snow right in the valley.

I think a decent moderate snow max for the Helderbergs and northern Catskills... but the biggest dump in the Taconics, northern/western half of Berkshires (north of PSF maybe) and southern VT. Pete is still very close to cashing in and any tick east he is back in the heaviest.

Wow the more I look at that it is very warm... we even start off as rain up here.

You can tell that stationary boundary is not moving anywhere quickly. 24 hours ago, we were supposed to be below freezing at the summits at this time with a strong NW wind bringing the cold air southeastward. Now H85s don't even fall till 21z or 00z tomorrow evening... a full 24 hour delay from earlier progs.

The good station to watch will be the summit of Mansfield for that H85 freezing line. Its still 37F up at 4,000ft and the wind is only "gusting" to 9mph. It was dead calm up there all day today which is really rare... shows just how weak the CAA is and we'll have to wait for the low to pass and dynamically cool us.

As usual I will watch MWN

After all, this threat looked pretty meh until day 4/5

Yes, I would say you can't totally rule it out, Going to need to some others models jump on board with it, Nam would be an outlier right now but, This threat was meh a few days back and we see what has happned with it so it will need to be watched..

This is one of those rare events where Mitch in Lenox might grill Pete pretty good...not often that happens, but its usually these CAA backside events it happens...that or upslope events. I recall a good in January 2006...maybe Jan 15, 2006 where PSF and Mitch's area got over a foot but then just on the east side of the slopes it was more 3-6"...we had like 2.7" here after the flip. But west of the spine they really got the cold air in much better and it took its time getting over the crest

I'm guardedly optimistic. I should be able to add to the seasonal tally. Magic will be in the air.

Nam clown map....def a lot worse than 18z for central and eastern areas...tho still a little tail in Essex county, MA

That map displays those oddities I discussed earlier on the NAM. It has the Berkshire snow, than nothing really near ORH where there is weaker VV and mid level RH...and then the comma head in ne mass and just off the NH coast. It might be a NAM quirky thing that fixes itself at 06z...so long that is does not go west.

Yes agreed. There is a lot of things to iron out with this system still. We have a long ways to go...anytime you get a vortmax that strong going south of us, there are some things to keep an eye on.

To all the folks relying on the messenger last minute SE trend, it's too soon, that doesn't start showing up until we're in RUC range, I advise patience to all the weenies.

JP is going to jackpot, can clearly see that on the RUC.

The sad part is no matter how many times the mets explain the differences between this season and the last several the weenies will still have their weenies out.

Good luck on the SE trend.

Yes, I think we might be seeing the NW trend continuing like we didn't want to see. Good for powderfreak....bad for ORH hills and the rest of the interior SNE.

Below

Slightly NW and warmer..

Really depressing if this is the pattern we have the next 4 weeks as I see nothing to stop this from recurring. Each cold push is muted even within a few days as we are finding here. The result is the cold air isn't even close as the storm approaches.

By 30hrs the 0c at 8h has pushed almost into Canada up near Maine. Ugh.
