Low was 7.0°F this morning, A little snow pack makes a difference.

LEW's UHI.  :lol:   Dipped to -3 here.  Hoping the firs will remain loaded thru Wednesday morning for the grandkids to see, as there hasn't been a flake at their SNJ home.  They're planning to arrive tomorrow, but it will be after dark.

We do need the rain, so…

It's so freaking pathetic how we can't get anything to work right for us. Actually have a decent shot for some phasing for once (and closer t o "perfect" than we've had) and what happens...we have a shitty airmass. So much for a "negative NAO".

This just further proves that there is alot more to things than whatever phase a certain teleconnection is in. The structure and where core anomalies are situated are a million times more important than whatever something is just positive or negative.

This proves that the Pacific is more important.

Anytime the pattern isn't perfect, there is a chance that it doesn't work out, but there are plenty of instances of RNA/-NAO working out around here.

You just can’t have the pna so negative. A weak pna would have made a huge difference in this current pattern

I do agree the Pacific does hold more weight overall, however, that's not always 100% definitive. There are times where (b/c of our latitude...more us than you) that the Arctic can be a significant influence. At the end of the day there are alot more factors and influences to consider than just Arctic/Pacific but those are the go to b/c they're "easy to assess". But in this case and to your previous post...a better positioned PNA would have could have helped but I think the evolution of that southern stream s/w is what gets us.

Tuesday night and Wednesday is a funky adventure into chances for a mixed bag clipping my neighborhood.

This has just come into better focus today and I am going to acknowledge there really is a slight chance of snow with this. I am not the only person who thinks this. Not much if any, but what if the current air mass is not fully appreciated. There’s a low of 29 Tuesday night where I live and I’m off Wednesday.

It’s not entirely impossible. NAM throws no bones though, but it was quite chilly this morning.

I've said it before and I'll say it again....many of our most prolific stretches have come during -PNA/-NAO patterns.

Is the majority of the initial cyclogenesis tied into the beginning of phasing or perhaps more of a byproduct of the gulf Stream? Maybe that northern stream vort is just a bit too strong as well here but this stupid zonal flow we have right now is probably the ultimate demise. nice airmass overhead now but that quickly gets shunted east.

From what I saw on the models I’m going to double down, I will be surprised if we get out of December without a 12+ inch storm in eastern mass. I believed in that last week, and I’m not going to give up over a couple bad OP runs. 

i believe in Santa, but that doesn't mean that he is going to plummet down my chimney on Saturday.
