Just as I thought, the models have all flipped back to warm and goodbye blocking again 

No blocking at all here, right? Just ignore the large orange and red blobs over Greenland. The PAC jet is warming the area up, and that's on the GEFS. The EPS is relaxed enough with it so that NYC northward is BN.

Hey do you look at models? The blocking is there. The Pacific is what is killing us some model runs look worse than other because the strength of the pac jet

that's been our issues the whole winter-doesn't really matter if we get ATL blocking, the PAC just overwhelms with that fast strong flow.

Eh, it will be cold the next three or four days. We'll be back into the upper 40's by Monday and lower 60's by Tuesday, middle 50's on Wednesday, upper 40's on Thursday, near 60 on Friday, and then upper 60's on Saturday and near 70 on Sunday, and then GFS tries to switch to cold again after that, but even normal by then is lower 50's.

Going to need a miracle at this juncture. Could happen but we're starting to get into the stretch (by next weekend) where accumulating snow becomes rarer for the coastal plain.  N and  W different story.

We're done with accumulating snow until December. I won't rule out a few flurries or some white rain.

I bet you'll be hard pressed to see overcast skies today. The system is way flat and South.

see Bluewave's thread-the threat is from an arctic front with steep lapse rates-some areas could get a quick coating.

That's the one I was refering to.  I'm not saying it will happen, but arctic fronts can sometimes produce a nice quick hit.

I saw it. The NAM has the line breaking up as it crosses NJ. The 12z RGEM is a little more bullish. The ground is very warm, so I doubt even if it comes down at a decent clip that it sticks on most surfaces.

True on all counts.  HRRR has some squalls.  Will help that it's near dinner time-so not in the middle of the day-could see a quick coating that ices up with quickly dropping temps, but this will be the exception rather than the rule.

Euro looks really good with blocking

How can you say this with confidence?

You can make this conclusion correctly 99 times out of 100 just based on climo alone. Add in long range guidance and seasonal trends and it's about as much of a lock as you can make.

Euro and gfs flipped spots. Even the cmc is colder than the gfs.

Did you see how the Southeast ridge was already reloading by day 9? Sure we have a chance at one last rogue storm, but I wouldn't count on it being significant snow, especially for anyone within 50 miles of the ocean.

You do know we average measureable snow in March, right?

Yes I'm well aware, but how often does it come after March 10th and how often is it more than a half inch? There is really nothing on the models that points towards a potential significant system other than a possible below average temperature pattern for a few days. We're getting that now, and it's stuck to the seasonale trend of cold and dry.

The Average March low in NYC is 34 degrees. The average high is 48. Climo certainly doesn't favor snow in NYC in March, espeically after the first ten days.

Climo doesn't favor NYC January and February warmth but it has happened and plenty of times I've seen march blizzards. EPS 12z run looks blocky and cold after day 5! Plenty of chances for it to change but you have to admit there is a potential for a storm coming our way late next week!

I never said that we don't have a chance of getting a storm, but I think the overall seasonal trends, climo moving forward and the lack of anything significant showing up on the operational models all make the odds of a significant snowstorm in NYC near zero.
