Euro ensembles have almost completely dropped the cutter/miller B idea. They looked really good last night with a nice cluster tracking from obx to east of the benchmark.

Too soon.  Psychologically, I get that most folks need to see a good solution/storm on the models.  But now is not the time.  I'm over needing to see it this far out.  Just hold the signal/storm somewhere in the vicinity and i'm good to go.   The southern slider look is fine for now.

EPS looks more stable. GEFS is all over the place last several runs esp beyond day 10.

 

On another note, Cohen says the -AO is still a comin, with some caveats of course(That darn B-K Sea low)

It's notable that the euro ens backed off the cutter/miller b idea. Now we have fair consensus of a coastal storm tracking south east of us. Whether we get hit or not is a different discussion of course.

Dr. Cohen has no choice but to say it's coming. If I were him I would. If the AO goes negative in Feb after being positive to strongly positive through DJ, can't it just be part of normal variability that can happen in any winter and that the SAI had nothing to do with it?

It's going to be hard to convince me it was the SAI doing it's magic but I'm just an armchair weenie so what I think matters little in the scientific community. In my eyes, the fact that the AO can be + to strongly + for the first 60 days of Met winter on the heels of what appeared to be a nearly perfect progression of SAI means that I probably shouldn't pay nearly as much attention to it as I did this fall.

IMO, the SAI and MJO based long range forecasting methods have both taken big hits this year.

Euro keeps the ridge in the w conus intact through the end. Hardly a surprise that the -AO dip could be transient. I hoped for the best there but was expecting a regression.

CPC D8+ has 2/10/06 as the top analog. Not a terrible thing...

Bob,  the D+8 and D+11 superensemble mean have prett good looks especially the D+11.  I'll start with the D+8.

 

It has 4 analogs have an inch or greater snowstorm. Below  I used the centered mean date instead of the date of the snowstorm

2/10/2006

1/24/2007

1/23/1988

1/7/2003

 

the 2006 storm was an 8 inch plus event

 

Without looking I would guess that is near or a tad above climo.

 

The D+11 has 7 analogs that had snow within 3 days.  Again, I've used the date of the centered mean rather than the actual snowstorm date.

 

2/13/1996

1/25/1988

1/17/1994

1/15/1957

2/1/1972

1/16/1959

2/8/1995

 

Four storms yielded over 2 inches.  The heaviest was the 1996 storm which produced 6.8 at DCA but had a stripe of double digit snows to the southeast.  I ended up with 12".  7 of 10 analogs showing snow is above normal.  That makes me feel a little better about yesterday's  outlook.

Thanks for this Wes. I started looking at other dates but work kept getting in the way so I quit. I knew the 96 date was good but didn't know what happened. Euro ensembles looked pretty good for d8-10. About .40 qpf and plenty of nice tracks. Best run yet. Not too bullish on the clipper though. Weak sauce here.

That's a pretty solid look. Suggests some snow is a good bet before the end of the month.

Compared to what has transpired so far a few of those dates would be ideal. There were some really nice storms and cold with some of those dates.

I definitely am.  A low forming off our coast and heading towards the BM.  Any chance this could evolve into something decent?  

Doesnt look like enough cold air in place to me..its essentially a low on the front, 9 out of 10 times we dry out before being cold enough...if we get any precipitation

Yup, it's killing the storm.  Could be GFS shenanigans, could be the makings of something.  Let's see what the rest of the 12z suite says.  And even so, doesn't matter at this point.

One positive of this run is that the clipper came south, and now gets light precip to the M/D line, instead of NYC-north at 06z.

 

A little bit more and we may get some snow.

It never had a chance. Terrible setup. The low north of the lakes destroys the surface and midlevels. We either get rain or we don't.

We're due some cold rain. 

 

It's kind of an interesting event.. if it happens as suggested. Santa Bomb was a similar type of deal from range and it ended up weaker than expected.

i think winter is over. Everything we see something good 8 9 10 days out....it falls apart. maybe its just not happening. Or maybe the new GFS PARA sucks

 

The only snowfall we've had so far since November was a renegade clipper... without that, we'd be 11-12 bad, minus the warmth.

i mean what fook happened. Models looks great yesterday. HM was ready to say Feb 2003 repeat...

 

Believing day 10+ model runs to the point of posting 850 temps? Talking about setting yourself up for disappointment. 

 

The seasonal pattern has been consistent and probably your best bet when guessing a day 10 forecast.
