That's not it necessarily. We need more potent systems. This one blew its cookies in the west and SW and it appears energy is limited when it nears our neighborhood. We know that poor Atlantics but good Pacifics have often produced great swfe snows but this one doesn't appear to be in the cards. Still very early though......and man it's going to be cold this week!

 

 

Yep, we've outlined many analog patterns and systems within this type of pattern that produce 10" snowfalls in Boston...did people already forget 2007 and 2008 with a hostile Atlantic?

 

I think so many have gotten caught up in the small sample size of one system petering out as it approaches us that I'm now reading blanket statements that are completely unfounded. If gradient patterns produced every single time, then Boston would average 70" of snow per year. Same with KU patterns...last January when we had a few sheared out systems, a lot of conclusions were being jumped to despite the pattern really not being all that bad for good storms.

I think that's the most frustrating part. We've outlined what a gradient pattern is and how it can and cannot produce sometimes...but it's as if people just ignored the caveats and only heard the term snow.  Sorry guys, sometimes December 2007 and 2008 don't always walk through that door.

As maddening as this pattern of arctic chill, and cutters interspersed has been, one must not lose sight of the fact that we are still in the first half of December.....which climatologically speaking, blows for snow around here:

Snowfall through 12/12/07 imby....5"     (Monthly total- 33.5")

Snowfall through 12/16/08....T            (Monthly total- 31")

Snowfall through 12/19/10....T               (Monthly total- 15")

 

Take a chill pill, and get  some shopping down......find a weenie place erect atop the xmas tree.

I think its better than it used to be inside of 72 hours but I tend to trust the GFS inside of 84 or 72 if it has a similar solution to its ensembles and the GEM agrees with it while the Euro shows something different. The Euro's biggest decline the last several years has been in the 7-10 day range, Days 4-6 I still think it blows the GFS away but it seems it has had problems with trying to break down or change patterns Days 7-10 and that its bias of overdigging in the SW has actually worsened, for that reason it constantly shows cutters all over the place in this range, I've seen it show cutters here with a raging -NAO on occasion, it never used to do that prior to its 2008 or 2009 upgrade.

Interesting thanks... did they think the upgrade actually upgraded? Like couldnt they have tested pre upgrade vs post upgrade verification scores in certain ranges to figure out if the upgrade actually helped?

It should also be noted, this is not the only storm chance in this pattern....you had just started posting back then, but you might remember the freakouts after the ice storm in 2008 (which of course didn't hit everyone here) when we had that torch and the 12/19 event hadn't appeared on the models yet except as a cutter in clown range on the Euro.

 

We had a day or two of meltdowns. Its early still...and this 12/9 system may still be pretty wintry.

I remember the meltdowns...I remember some angst in 2007 too regarding the Atlantic.

 

It's definitely early...I'm not saying this month will stink....I'm just saying some people  have visions of 2007 and 2008 working out...but it doesn't always work like that.

 

FWIW, I;m still intrigued about this month and the pattern down the road.

I admit I thought we were heading for something similar.

 

and now Mondays system is tanking. seems like these are trending towards fizzling out for us but they are producing pretty well in the south MW for sure.

Yes...not every analog pattern produced. This one still easily could too...but about 25-30% of the analog patterns left us relatively snowless.

An inch or two of snow and glaze is pretty wintry...guess its just how you define it. I'm not impatient this early in the season...not every event has to be 6" of snow for me to enjoy it.

 

The 12z GFS actually isn't too bad for QPF down this way (south of the Pike) but the problem is, it occurs during the day and the thermal profiles seem to support more liquid than frozen precipitation
