Yes but that was a pattern that was bad for the coast.  It was good for areas to the far northwest of us.

Because it was November and your departures of - 5 still don`t get it done on the coastal plain without blocking that early.

 

There was a trough in the means at 500 because you were in the cold phases.

 

Now what does that pattern do in late Jan to Mid Feb with where N are at that time ?

Yea, I was confused as to why it was being called a good pattern. It’s strong -PNA/RNA, +AO, +NAO, neutral EPO

and a strong PV to boot.  Not exactly the stuff of big winters around here...Great pattern for the Rocky Mt Ski resorts

Going to need a monster -EPO to overcome the other garbage

any storm that cuts west of us could easily bring in more record warmth. look at that trough to our west

Sure over the next 5 days when there a 4SD ridge in the east , I think I hit 70 in CNJ.

But then hat ridge is pressed down into Cuba day 11 - 15.  If you cut any storm in even the best pattern we can go to 50. But the EPS accelerated kicking that trough off the W/C by day 10.

It`s p7, the trough doesn`t come all the way east.

But here is the EPS storm track post d 10

The first half of December was pretty meh too....now once you get to the end of the month and especially February, you're talking, but that was what many of the LR forecasters said anyway, that this would be a backloaded winter.

I think he means that if the pattern was really that good that storms wouldn't be cutting or hugging.  Cutting/hugging is the effect, not the cause.

PNA goes + 

And there`s height heights over HB.

 

I didn`t say it was " a good pattern " I said your SE ridge and torch are gone.

 

And in Jan you snow with N 2m`s with - 850`s

Paul, is there a way to come up with a list of analogs of other Januarys that went into a similar pattern?

I have no clue what some people on here are seeing. Either they dont look at the models or they are trolling.

Expand  

you have to look at more than the models.  Surely you know that by now.   They're a tool.   Part of a package.   Just b/c a day 10 prog says x or y, that's certainly not always the end result.

I'll give an example-several days ago models had an ice storm for Cleveland this weekend.   Now they have thunderstorms and record warmth this weekend.

Expand  

 

Brian, with all due respect we have been talking about a 3 plus week warm up away since before Christmas and hollowed out a 5 day break with more warmth on the backend.

 

No one where I post missed this period from late Dec onward.
