Upstate NY/North Country + adjacent ON, QC, VT: Heading into Fall

That Lake effect band died on the way back south through here. Still picked up a good amount though, but nothing compared to 5 miles south of here the last 2 days. 20 inches difference in just 5 miles! ^_^

 

All the models have increased QPF with the system on Saturday. Might be a little more than originally expected, but as we know bust potential is high with the storm off the coast becoming the primary low.

Wow. Not a single model in the last 4 days showing less than 6" of snow in Ithaca and Binghamton gives us an advisory for 4-6? Pathetic. Zero support for their forecast, beyond an analog from January 2011 where the jackpot zones for this storm got 5 inches.

But at least we're getting some "bonus" snow already ahead of the main show. Didn't expect it to be that snowy all day. Looks like about 2 inches here since the morning already with continued light snow.

BGM WFO definitely taking the "under" on this next storm. 4-6" for KSYR looks a tad low based on qpf fields, though these are among the most unreliable of the various NWP outputs.  FWIW, a quick eyeball of NWP shows both NAM and GFS 12Z spit out about 0.7" liquid at KSYR for the storm.  That's about 8.5" at 12:1.  Given today's hype machine world, I'm surprised BGM hasn't jumped on the WSW bandwagon.  I will say KBGM has been pretty good w/ LES for No. Onondaga county this week (5" on my snowboard and maybe another 3/4" since noon, total of 8" IMBY for the entire event).

Yes, the snow "showers" for today definitely overperformed. If nothing else, virga won't be a problem with this storm. Where in Ithaca are you?

I've never seen such model consistency for our region for a winter storm(different story near I-95). Since Monday it's been a general 6-8 across nearly the entirety of upstate NY, with 10-12 inch lollipops. I get taking the under since that's what I usually do, but there's almost always at least one dissenting model which I can hang my hat on. What's really crazy is putting even the Catskills under a WWA, there's no way they get less than 8".

I'd go 6-10" for Niagara Frontier.  I think 4-7" is a touch too low.  Snowgrowth is excellent, modeled qpf is somwhere between 0.55 (euro) and 0.75" (NAM).  The number CIPS analog is Dec 15, 2007...an event where BUF saw 12" and Lockport saw 18".  (That shortwave was considerably stronger than this one, though.)

That's a good point, model consistency has been "unusually" good w/ this system the past few days for New York state.  BGM's AFD has had this nugget buried in it regarding this storm, the past day or so...

"MODEL SOUNDINGS ALSO INDICATE SNOW GROWTH REGION NOT COINCIDENT WITH THE BETTER MOISTURE OR LIFT IMPLYING A LOWERSNOW/LIQUID RATIO."

 

Perhaps this is why they are lowballing a bit. I haven't looked close enough to see if that's still indicated on NWP.  Perhaps also the double barrel structure of the system is concerning, we've seen cases where the primary hangs on too long and some interior areas between the sfc lows get semi-dryslotted.  I don't really see that here but its out there as a possibility.

I could see us getting "bit" a bit by an earlier dry slot/qpf cutoff....esp. with a stronger "zombie" primary.  As a matter of fact, it would not surprise me at all to see a few shallow warm layers providing some pingers late Sat. night before the secondary takes off.  I think SYR sees 6"....but not much more.

and it's still snowing... guessing we got close to 4 inches by now. I'm on the west side of the lake at about 1,000'.

KBUF also thinks the QPF is overdone and mentioned earlier it depends how early the transfer is to the second low.

Yes, for you guys and gals in the western part of the state, the speed of transfer will impact you more, as forcing/lift may diminish rates out your way.

 

Over CNY, we may benefit from better placement/location relative to the strengthening 700 and 850 height fields...long enough to buffer any rapid negative effects from llv forcing from the secondary deepening.  I'm a little worried about a stronger primary...we (W. and CNY) can and have get/been screwed by llv warm layers that crash our ratios, and sometimes, turn us over to a small flake/drizzly pile of crap.  Let's hope my concerns are just paranoia!

The new NAM is juicy for CNY. Wow! Picked up 5" in Phoenix this morning in about 2.5 hours. Nice.

Yeah, our area via the NAM is solidly into 1" of qpf.....even shaving off 40% gets us .6....and at 12 or so to 1 we are looking at a solid 7-8".  If GFS trends a bit wetter than it has, I'd look for the NWS offices to entertain upgrading to WSW's for CNY counties.  Otherwise, it's probably the NAM just being the NAM 18 hours before a storm!'

 

We've seen this dog and pony show before....like clockwork!!!

I actually thought Binghamton would of done the WSWatch for us. You guys are the pros but what I am seeing says it could rip for a bit tomorrow night with 1" per rates with a decent east southeast wind. Thinking of the trhuway corridor down the Mohawk. Travel may be tough around here after 9 or so.
