Man, so close to a blue nuke on the euro...get that good omega/lift just a shade further northeast into SNE, and we're parachuting. Instead, we get mostly very light rain on very gusty ENE winds.

With slightly less blocking that hour 66-72 panel time frame would make you think New England is about to get destroyed... then it's nope, shunt SE.

Damn Storm Surge ya got me in the fishing mindset, one truly beautiful area. Taylor Swifts beach is a beach break nobody surfs there, right around the corner at Watch Hill lighthouse different story, if ya got the balls. According to the Watch Hill Lighthouse keeper, during Sandy the waves were crashing up to her lawn and spray was going over the house. That is over 50 Ft to the lawn and 100 over the house.

12Z settled nothing. what a PITA evolution. Don't like the UKMET or Euro late bombs, we may miss this

My only hesitation is that all the spread remains north, and the Euro op is close to being THE outlier solution within its own ensemble. 

Fair point. I'm wishcasting the death of this thing.....some courses around here are starting to partially open...

Can you see or do you know what 700mb temps are on the Euro? Tough to tell from what I’m looking at but based on color scale looks like around -5C??? Isn’t that a tad too warm for snow production?

Spread on the GGEM ensembles was NW just like the GEFS. I am cautious about writing off the GFS evolution.

The NAM looks way to fast with the southern shortwave, that is the only solution I am inclined to throw out from 12z.

We have had a lot of northern stream dominance this winter, Tough to think that this go round its going to crap the bed in the end.

weather.us has them

And it's only a problem if that is the top of the cloud layer. Plus you can expect plenty of salt nuclei with the deep E flow.

-5C is marginal in our salt-nuclei infested environment in SNE...prob too warm if that's the absolute min temp in saturated column....but you likely have saturation above that for seed-feeder even if the lift isn't great above that level.

The 850 temps are marginal on the euro...around 0 to +1C...but that is with crappy lift. The bulk of the dynamics are to our south and southwest, so if you bring them into SNE, then we're prob getting a paste bomb over the interior. A euro solution that is a little more robust would probably be in the sweet spot to maximize the snow out of this marginal airmass. You obviously don't want to get it amped to the point of GFS-esque flooding the interior with warmer mid-levels. You want the nose of that LLJ to be further east.

Big differences 12z GFS versus Euro in evolution I believe can best be pinpointed through 48, and it's the Southern stream shortwave that's holding back too much--this is a critical and well known bias of the euro.

You can look at previous runs of the euro and see that when the energy isn't held back in the SW, the evolution becomes very similar to the 12z GFS....

She's going to be tucked in folks.

Weather.us

Depends upon time frame but they range from -6C to -10C in CT.

Which it likes doing.

I will say that there has been a multi-run/multi-day trend of having this thing hang back more out there. In tandem, there is a multi-day trend of higher heights over the E CONUS in the 12z tomorrow timeframe. One of the reasons I am suspicious that this might be coming north more.

LOl I just saw this, actually would be ironic as there are a couple of know it alls posting and tweeting about how it's impossible for NYC to have a snow storm because there is no cold air around, rooting for it if we miss. Congrats SW CT peeps though

That is just sick for Ct; a state divided..   Looks like Mexican wall has been displaced a couple thousand miles.

Thank for for the info! 

Did either of you find something odd with the 2M temp outputs? Looked like the 2M temps absolutely crash region wide from 6z to 12z to below freezing but then shoot back up into the 30's by 18z...and it was a substantial area this happens...basically from SE Canada down into CT. I thought maybe we had a period of like northerly winds then went easterly or something but that wasn't the case at all.

well... 'on the coast' there is still a warning potential for CF/tide concerns... is that what you meant

Well I'm about 4 to 5 miles from the coast as the  crow flies so street flooding might be an issue.   Snow is more of a financial concern to me at the moment.
