January 25-26 Storm Potential

Eh haha...yeah.

 

I'd say what it all really boils down to [for those emotive about all this...] is that when you are in "one of those patterns", it seems as though fart in china makes it snow here.  There have been a few of them in lore.  Couple years ago we had a 45 day, 60" blitz, then going back, a sprinkling of years over the past couple of decades had intervals that snowed at least excuse imaginable.  This year, at least so far, the opposite is true.

 

But it's always been that way.  It is almost like fractals, where you can be in a "chancy" period where randomality flips tails more than heads, and you end up in funner times.  This year, we're flipping more heads.  About 10 days ago, I remember when Will said something to the affect of, with all that cold air and that trough it is hard to imagine it bringing the goods eventually.. . Well, hehe, D7 and counting the b-bangs.  This 12z Euro run is microcosm of that;  Whiff - whiff - Lake cutter - dry and cold.   Just perfectly and quintessentially wrong.    

 

 

straight question, are people wishcasting on this event right now in your eyes?

I thought the GFS had decent WAA at 850. It won't take much to wring out snow in this pattern.

 

yeah the 12z run had a pretty strong LLJ off the mid-atlantic...it doesn't quite get this far north but like you said...this kind of airmass...shouldn't take much. just some weak upglide would be enough. 

 

crosssection from about ACY to BOS 6z sat. :

How's powder freak doing wrt snow. I think theyv'e been pretty dry up there. Perhaps below last years pace

 

Been dry... but we are ahead of last year's pace both in town and at the mountain.  Last winter was really low with 85" in town and 210" at 3,000ft.  With snowfall in the low 50s so far in town, February/March/April would have to absolutely blow to not achieve more than 30-35" from here on out.

 

Right now we are on pace for a below normal snowfall winter, but nothing unheard of.  Like a 250-270" winter at the summit and 100" in town.  We'd need to only get less than 80" at the summit from here to the end to be below last winter.  Doubt that happens as we can jam out over 80 inches in 2-3 weeks in the right pattern (like earlier this winter with 85" in 20 days).

No, not actually.   As of 12z, the S/W dynamics responsible for ...whatever ultimately transpires, were just barely tickling the west coast of N/A - much of it is still over the open eastern Pacific/GOA area.  

 

Normally,  72 hours out for that.  But here, the flow is so fast that it's almost halved that amount of time, such that we may only get 36-48 hours lead before a rapid adjustment back more intense and NW happens.   

 

That's not a wish.  It is a hurry up and wait.  It doesn't happen every time.  Much of the initialization grid for those open oceanic areas are assimilated and satellite sounding combined.  It is what it is, and certainly better than having no input at all!   But, once in a while, an important system shows up in the late middle range period, disappears, only to come charging back in nearer terms ... usually when that happens the S/W comes into B.C. or the Oregon coast when the storm comes back.   Now could be one of those times... we'll see.  

 

This initialization of 00z and particularly 12z tomorrow might be a time to look.

For what its worth.. if you take the GFS and look at it.. it has been the most consistent model recently, mostly because it has not had wild swings back and forth, just slow trends..

 

Lets take the 12z gfs qpf. which was .20" OXC and .30" qpf for GON. This track storm will lock in cold.. and temps from surface to 700mb will be -20 to -10 C giving a 20:1 fluff factor for most..

 

That gives us 2-3" under a 10:1 ratio. But under 20:1 ratios this could be a 4-6" snowfall for Southern New England.

 

Question remains is this storm still trending south and the GFS just had a hiccup at 12z, or is the gfs onto something and it might even trend a little more NW.. If 18z holds or trends at all NW I will be excited for a light to possibly moderate snowfall..

Did you guys notice this NAM run?   The next 48 hours witnesses a top of the physics S/W power ripping off the MA... 120kt at 500mb, about at a theoretical limit perhaps.  This feature's axis rotates around neutral as it leaves the MA, and a Gulf Stream detonation happens - 

 

this low rotates up E of NS and bombs all the way down to a Category 3, mid 930's mb low!!

yea I posted that too. This up grade is on par with the euros, if it aint broke do not fix it

Cool... when we get hacked into oblivion because we're using outdated and vulnerable software, I'll bump this post.  The upgrades are not really optional and the board is highly customized, so every update is going to have issues that take time to get resolved.  Some of the issues, like the editor, are entirely beyond our control.

Cool, so it was a security upgrade, with the transparency and all did not know, thanks

Bufkit for area shows 3-4 inches on GFS ratios about 17-1
