Did any of the models show you getting a 1/2" or more?  Just trying to figure out which model may have a better handle on this storm.

I've been watching the oven mitt thumb area of Michigan (around Saginaw) as an indicator of how north the mixing line would get. According to wunderground radar, mix line is just barely north of Detroit....let alone close to Saginaw. Warmer models runs had the mixing covering nearly the entire thumb of Michigan...but there is still time for that to move. But don't think it really was suppose to once that line was setup....

So it looks like some of the areas may get less ice than expected back in Michigan.  The 3K NAM is putting out some big freezing rain totals out to our west.  I don't know if that means some people further south end up with unexpected freezing rain, which is probably worse.

I do know one thing, I'm going out to gas the snowblower and make sure it cranks easily.

Yeah, the short rangers were all in that Coating -1" range. No zr in town, which is what happens the majority of the time, so any amounts shown were overdone there. As @MDBlueridge would say, know your region. Haha

Starting to shower some nano-sized flakes about half an hour ago...as the radar seemed to dry up oddly enough.

Woot, woot...just saw Burlington flipped me over to a Warning....

BTV's most recent forecast discussion.  It talks about the dangerous conditions tonight with little visibility at times.  They mention near blizzard conditions tonight, but I don't think the wind will be blowing that hard during the overnight hours.  I think tomorrow we may be dealing with blowing snow as winds increase.  As @telejunkie alluded to, they increased QPF amounts for southern VT and upped snow totals.  They bumped my forecast to 7"-11" for tonight.

.NEAR TERM /THROUGH FRIDAY/...
As of 339 PM EST Wednesday...

* Winter Storm Warning in effect this evening through Thursday
  afternoon.

* Combination of heavy snow and mixed precipitation will make
  travel difficult for Thursday morning and evening commutes.
  Gusty winds and blowing snow in the Saint Lawrence Valley will
  result in near zero visibility at times making even a short
  walk tonight potentially deadly.

* Additional light snow accumulations and mixed precipitation
  are expected Thursday evening into Friday with cold, blustery
  conditions following Friday.

The much discussed winter storm is on our doorstep currently moving
through central New York State. Snow is expected to begin 6-11 PM
local time this evening spreading from southwest to northeast. Main
messages of hazardous travel conditions for the region remain true
although some of the details changed marginally today. QPF increases
across southern Vermont warranted more snowfall than previous
forecast cycles and pushed western Rutland and eastern Windsor
counties over the threshold of warning criteria. Also, increased the
amount of ice in the early Thursday morning period where drizzle and
periods of freezing rain are possible. A glaze to several hundredths
of ice will be possible on top of the expected heavy snowfall.
Blowing snow remains a threat for those in the Saint Lawrence
Valley. Visibility will be nil at time tonight as heavy snow and
winds create near blizzard conditions. Those heading outdoors could
become disoriented and even a short walk could be deadly.

Outside of some off-cycle 18Z CAM guidance, expected conditions
didn`t change too much from previous runs. 12Z guidance continues to
favor strong isentropic lift across an approaching frontal boundary
that is expected to largely stay south of the region. NAM guidance
has come more in line with global models in this regard although
model atmospheric profiles continue to vary. Kept the large nod to
NAM and CAMs for profiles to keep sleet and freezing precipitation
in the forecast as winds aloft increase. Global models, GFS and
blended guidance, remains too cold and doesn`t capture the warm nose
as well.

Main changes were an increase in QPF over southern Vermont resulting
in more widespread 6-10 inches across Rutland/Windsor counties.
Elsewhere, error bounds are creeping towards the higher end of the 8-
12 inches of snow expected with median values in the 10-11 inch
area. From a probabilistic approach, models are favoring slightly
more snow than previous runs, but not outside of the original
forecast envelope. Some modest adjustments were made to ice
accumulation which continues to be the element with the highest run-
to-run variance. Could see some freezing drizzle farther north and
east in the mid/upper level dry slot early Thursday while freezing
rain becomes increasingly possible for southern Vermont later into
Thursday as cold air sags southward. The result was a light glaze up
to around 0.1" of ice behind tonights heavy snow.

Otherwise, cold air advection will increase Friday with blustery
conditions expected as northerly winds gust to around 20 mph.
Ambient air temperatures will drop with highs from around 10 degrees
into the mid/upper teens. Winds and low temperatures will create
wind chills from the negative single digits to the positive single
digits in general.

Really wish my driveway was a little firmer. The top inch or so is definitely soft, could make snowblowing harder than it should be.

  Thinking there will be a battle near me (hopefully further NE), between that cold, relatively dry feed from the NE.  The cold should help ratios, but it is too dry, that'll offset to some degree.

Took off early, saw it all on the way home. Rain and 40 at Long Wharf, snow mixing in Milford and along the Merritt.  Just snow in Monroe, covering the ground in spots at 32°. To a mix of sleet and snow when I took the garbage cans in.  Deck temp 36, but car temp was 32 and surrounding stations 33/34

Some snow showers here, waiting for it to kick off. Call me impressed, check out the warnings out there.

Not a SNE storm but hope you guys get hit good up north! Good luck MJ, hope that warm nose can be kept at bay up there.

Stretch, you thinking sleetfest or more ZR down your way?

Kinda thinking we're done.  Maybe it gets to 32 and there's some fr drizzle but the next batch is in ILL and I don't think it holds to here.

Upton said the warm front would stay south of LI. Looks like they were pretty good with that. Temps in my area borderline for a freezing event.  84 seems to be the line. There’s a abandoned property down the road that’s hosting tree and utility workers and their trucks. Hoping they are needed elsewhere.

Closing in on 6" now.  Very fluffy, 15:1 easy.  Windy enough to make it feel like a blizzard snowblowing with the snow flying aroun

What's that white all over the ground???

 

For you Gilligan Island fans (dream dialog)...

Gilligan say they have thing called snow.
What is snow?
Is white, lumpy rain.
We don't need rain. We need husbands.
Men on this side of hill run too fast.
Easy for man to slip on snow.
What?
Easy to catch man running in snow.
Man run, slip on snow,
Girls catch husband.
Ooh, other side of hill sound very good to Mary Ann.
Sound good to Ginger.
We like snow.

I'm about to venture out to take my son to work and it looks like we have 5" to 6".  Snow had stopped a little bit ago but now starting back up with larger flakes.  Currently 17F with no wind.  Today's forecast calls for a few more inches but has taken out the mention of freeing rain.  It does mention sleet for tonight.  Expected high is 22F.

BTV's discussion for this morning.  Dryer air did cut down on totals.  Maybe part 2 of this storm will surprise to the upside.

.NEAR TERM /THROUGH FRIDAY/...
As of 710 AM EST Thursday...Precipitation has dwindled to
patchy light snow at this hour, with the drying aloft taking its
toll on our snowfall. We are still seeing rather breezy
north/northeast winds in portions of northern New York and
northeastern Vermont where low level cold dry air continues to
overpower the cloud layer above it, so expect some blowing snow
especially in the St. Lawrence Valley to continue this morning.
Also have received reports of freezing drizzle already so expect
patchy freezing drizzle will become more widespread across the
region, especially in areas with higher relative humidity. Cut
back on storm total snowfall based on observations of generally
2 to 6 inches this morning, but additional light snow later
today and tonight will help boost us closer to early
predictions.

VT and vicinity snowfall map from BTV. It is through 7 am so it was still snow in many of these places at that time. I measured here and 5 1/2" seems to what we received. I took care of the driveway and I don't think we received any sleet. The snow was like sand in consistency and easy to get traction.
