I'm going with a generalized 2-4" across all of CNY for today's event, with some places reaching 6" where they stay under the band a little longer. The 6z GFS also backed off its crazy solution from last night, so hopefully that was just a fluky run.

I'd agree with those numbers for CNY from the clipper/front.  Probably not entirely dissimilar from Sunday but perhaps not as strong of a single super squall line. 

 

I can't even ascertain what to expect from LES.  Between KBGM and KBUF discussions, I might expect occasional snow showers or possibly thundersnow. I'll go with past history, where 3-7" of LES is most likely IMBY. We just don't get outrageous totals here typically.

 

As far as Sunday, I think I saw KBGM's disco actually stated that there will be no HP in place, thus the rain.  They clearly are all aboard the GFS trend as of last night.  Granted, the core of the cold will be rotating northeast but there's a fairly deep trough and push of arctic air that this system will be running into.  We may get multiple waves but I suspect WNY/CNY will see more frozen than liquid.  If there was a single concentrated slp/h850 low that tracked over CNY/WNY, I could see a warmer solution. If smaller/weaker waves move along a boundary, a colder solution should verify.  This is still days off so we'll see but I thought it curious that AFD's would be talking about such a warm solution and multiple smaller pieces moving ENE...

00z GFS, IMO, was way too amped...the GEFS and subsequent 06 runs/ensembles paint a much colder/frozen picture.....I think C/W NY will be fine wrt p-type issues....

yeah, 6z GFS looks pretty amazing for us, plenty of time to see which way this develops.  With the arctic air in place, I tend to think we'll see a colder solution.  Fortunately, we have plenty to "enjoy" between now and then.

Yeah, late this afternoon into the evening should see a few hour period of pretty good rates (1-2"/hr.)...then a bit of a lull before the LES sets up late tonight in earnest.

LOL! Part of the AFD out of Gaylord, MI:

WELL...WE HAVE GOOD NEWS AND BAD NEWS NORTHERN MICHIGAN. THE BAD

NEWS FIRST - TEMPERATURES TO ROUND OUT THE WORK WEEK MAY WELL BE

COLDER AT TIMES THAN THOSE SEEN THIS PAST WEEKEND...WHICH IS A SCARY

THOUGHT. THE GOOD NEWS? JUST KIDDING...THERE REALLY ISN`T

ANY...UNLESS YOU ARE A BIG FAN OF EXTREME COLD...OR YOU COUNT THE

FACT THAT CLIMATOLOGICAL AVERAGE TEMPERATURES ARE ACTUALLY ON THE

INCREASE. SADLY WE WON`T COME ANYWHERE CLOSE TO AVERAGE THROUGH

FRIDAY...WITH THE DISTINCT POSSIBILITY THAT MANY SPOTS MAY WELL

STRUGGLE TO GET ABOVE ZERO ON THURSDAY AS SOME OF THE COLDEST AIR IN

THE LAST 20-30+ YEARS IS PROGGED TO SPILL DOWN OVERHEAD. TO PUT IT

IN PERSPECTIVE...THE COLDEST 850MB TEMPERATURE RECORDED DURING THE

APX RAOB YEARS SINCE 1996 IS -28C (NEARLY TIED THIS PAST

WEEKEND)...WITH THE COLDEST IN THE SOO ERA DOWN AROUND -31C. 00Z

GUIDANCE CONTINUES TO PEG READINGS DOWN AROUND -30C TO -31C BY

THURSDAY MORNING - CERTAINLY EYE-CATCHING FROM A HISTORICAL

PERSPECTIVE AND VERY INTERESTING FOR US FORECASTERS.

Buffalo Weather, I'd be amazed if this weekends storm turns into a rain storm for your Ski Trip. Just would be a complete change in a very consistent weather pattern. Which is NOT advertised by the overall shceme of things. At least not for the next 2-3 weeks. I went on a Bachelors party to Ellicotville last winter. What a great town! I hope you have opportunity to get to the brewery bar. Get the 30 dollar burger. It is worth it.

 

Yeah Ellicottville bar and brewery is amazing. We always go there when we go skiiing.

 

1-2' for some lucky FEW by Friday afternoon (today's synoptic burst, followed by a delayed LES response..but a decent one!)...The band will be narrow, but intense. Area still looks like S. Oswego Co./N.Onondaga Co. and back toward the lake (clipping extreme N. Cayuga Co.)

BUF is indecisive, but need not be. BGM will play catch up. Flake size will be decent for a good portion of the event (esp. Thurs. late morning into the evening).

 

2 inches per hour snowfall rates and only go with an advisory sounds kinda crazy.

 

00z GFS, IMO, was way too amped...the GEFS and subsequent 06 runs/ensembles paint a much colder/frozen picture.....I think C/W NY will be fine wrt p-type issues....

 

You're definitely right. Most model guidance has went away from the super amped solution to a more progressive overrunning event that was already depicted in most ensemble guidance. I am still worried, but not as much as last night.

It's hard to see a way out of this.  That strong surface high building over the Western/Central Atlantic is going to really work against us, just not enough blocking at all.  What a disastrous run this was....

Yep, seems clearly that the s/w in the southern stream is much stronger than earlier progs had shown....should be a pretty quick mover though....snow...12hr. period above freezing with rain...then back in the ice box!!

From BGM:

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...

AT THIS TIME IT APPEARS THAT THE BEST INSTABILITY FOR SNOW SQUALLS

GROWTH EXPECTED TONIGHT. OTHER UNFAVORABLE FACTORS FOR LK SNOWS IS

THAT ONTARIO IS ALMOST 80% COVERED IN ICE AND UPSTREAM LKS HV BEEN

PRETTY MUCH TAKEN OUT OF THE EQUATION.

WIND CHILL TEMPS TWD 12Z DROP INTO ADVISORY CRITERIA RANGE WITH

HEADLINES WELL IN HAND.

As I said during the "surprise" LES event over NIA and BUF before the prior storm, the geography is often overlooked, wrt the organization of a convergence zone over the long axis of Erie and Ontario. Initially there will be "some" ambient moisture, which will get the band going (probably around 8-14z Thurs.) There is enough open water over the lake to have a substantial band form. I think BGM, NewsChannel 9 are both way underplaying the potential for this event....it won't be a blockbuster, but IMO, it will be significant. BUF seems on target....but certainly in a cautious fashion.

Its just incredible to me how that KBUF snow map completely contradicts what KBGM is forecasting? How can 2 forecasting offices, adjacent to each other, have such contradicting forecasts? Makes absolutely no sense, at least to me!

If you're in Belgium BGM expects 2-3" on their map and cross the county line and BUF says 14-18". Fun.

Us SUNY Oswego forecasters that provide DOT forecasts are middle of the road at this point

That's about where I am at. Per KBGM, basically 2" per forecast period, so let's extrapolate that to 6-7" by Friday afternoon. Right across the river in Phoenix, about double those amounts. And the KBUF forecast map has 10-14 for Phoenix and 14-18" not that far away. Let the games begin.

Most of that is rain or freezing rain as the surface low tracks over BUF and toward CYUL, 18z GFS is much more suppressed and looks to keep you guys all snow.

6z GFS was more suppressed also, following last nights 00z warm run. Too bad the "off hour" runs are usually less reliable than the 00/12z runs.
