Back to Back Major Synoptic Snowstorms!

We've had our pre-pre game snowfall all day here in the Syracuse area. Probably the cloudiest day of this month with light snow falling all day. The heaviest of the day has been falling the last hour. Looks like the NW winds have brought sunshine to Buffalo and even Rochester?

Was awesome this morning.  Bright sun beaming through on the flurries.  Been clear blue skys and sun past few hours.  Just got done scrapping the driveway and sidewalk down.  Ready to go now!

My calls, will do a final one tonight after the 00z suite.

 

BUF - 13.3”

ROC- 17.1”

SYR - 14.4” (except 1.2” at Matt’s house) 

ALB - 5.3” (mix issues)

BGM 6.8” (mix issues) 

 

 

That's a bullish call for Matt's place. I'll take the under. ;)

Watch. The EURO is going to be great. We’ll all breathe a sigh of relief. Followed by 18z NAM with sleet to the lake and I’ll be back in the basement looking for my length of rope.;)

I don't give a rats f*cking azz what the 18Z NAM shows.  Pretty much, ever. ;)

I see what KBUF did. They didn’t include the first round of 2-3” of snow tomorrow. The WSW begins at 7pm tomorrow, so if you add up 2-3 on top of 6-11 you get 8-14”...odd they didn’t combine the 2 as totals will be higher than they’re suggesting 

Kept em separate to fudge numbers. Typically buffalo

I did but I deleted it because I thought it was old lol

After a brief lull in the snow Monday afternoon, a second and much
stronger jet will emerge from the Ohio Valley Monday night, with the
right entrance region of a 160+ knot 300 hPa jet streak passing over
our region. Additionally, a mid level trough just east of the Four
Corners Region will pass across our region Monday night and into
Tuesday.

Lower in the atmosphere a 60 knot LLJ will advance northward along
the east coast, with the left exit region nearing our region. The
12Z ECMWF continues to better align with the GFS in maintaining the
axis of this jet closer to the eastern seaboard, while the latest
GGEM solution keeps it a bit further to the southeast. Nonetheless,
this LLJ will aid in deeper Gulf of Mexico moisture transport from
the south, which combined with the increased lift from the passage
of the mid level trough and jet dynamics, will bring greater
confidence for a heavier snowfall late Monday night and into Tuesday
afternoon. This swath of synoptic snow will likely bring more
significant accumulations to the area Monday night into Tuesday.
This swath of synoptic snow will likely bring more significant
accumulations to the area Monday night into Tuesday, and we will
maintain the winter storm watch as is with this forecast package.

Looking at CIPS analogs, most of the events within the analogs did
bring warning criteria snows to our region. What could hold back
snowfall totals will be the placement of the SW/NE oriented
baroclinic boundary aloft, and if it will back westward enough to
allow warmer air aloft to bring a mixture of sleet or freezing rain
along the southern fringes of the CWA. Model guidance continues to
keep this boundary just far enough eastward that the area will still
likely see an all snow forecast, but latest model guidance nudging
it a bit further northward warrants close monitoring moving closer
to the event. As the system pushes northeastward, colder air will
filter in from the northwest and cyclonic flow will allow for some
brief lake enhancement south of Lake Ontario through Tuesday
afternoon, before the dendritic growth zone loses the deeper
synoptic moisture. Upslope flow in the Southern Tier and on the Tug
Hill may lead to a minor increase snowfall amounts in those areas
through Tuesday.

For snowfall totals, the potential for over 9 inches remains
possible, with majority of the snow falling Monday night and into
Tuesday. By Tuesday afternoon a dry slot will be pushing northward
across the state line as a deformation band of snow across WNY lifts
northward, with synoptic snow finally tapering down.

Tuesday night, cold air advection embedded in a NW flow could bring
lake effect snow back to areas south and southeast of Lake Ontario.
Moisture will diminish through the night as a spoke of a strong
surface high passes across our region, which will also lower lake
inversion heights. Behind this trough Tuesday night will be cold
with single digit lows across WNY, and below zero east of Lake
Ontario. If we can clear out sooner (outside of lingering lake
clouds) several areas could drop even colder than what is forecasted.
