Elevation is 1240' (it's also in my signature), I cleared at 10pm and then again at 6 am but did not do an on the ground check.  We were wiped clean prior to yesterday so I would guess it is about 4"

Can't see sigs on mobile thanks enjoy

GFS is like 5” here and then a period of ZR midday Sat. It probably won’t equate to much glazing given the time of day and year.

What’s 2m look like on Sat? Goofus has a period of ZR here after 5”.

Have to say LR models including Euro weeklies have keyed on this storm for a month. Just some variations N/S but qpf/ baro and cold all advertised for the great white North. (Hint if they are right it aint over for you upper elevation peeps)

Anniversary today of the Morch firehose storm in 2015. That was the last time Morch was March and winter. Since then it’s gone for good 

lolololol I love these definitive statements. how about some data:

in the 9 Marches up to and including 2015, I averaged 11.75"

in the 8 Marches 2016-present, I averaged 11.5"

yeah, a whole 1/4" less.

BTV hitting the uncertainty

Concerningly
the latest ECMWF came in very wet (snowy) with storm total QPF
in the 1.7" to 2.4" range across most of Vermont, and about half
of its ensemble members do have greater than 2" in south
central Vermont. This dramatically wetter idea than other global
models may be tied a quicker development of a strong upper jet
Friday night, and subsequent phasing of the northern stream and
southern stream systems, leads to a deeper and more westward
coastal low track on Saturday. Given these differences, there
unsurprisingly is a large and unfortunately growing spread in
our low end and high end snowfall amounts; as an example,
Newport, VT, currently has a mostly likely amount of 8" with low
end of 3" and high end of 20". Part of the challenge,
especially farther south, will be snow ratio forecasts.

The snow ratios are rather uncertain similar to snow amounts when
you look at the spread amongst model guidance, particularly during
the daytime on Saturday. The interquartile range in the NBM snow
ratios in a swath from the Adirondacks eastward across central
Vermont is about 5:1 to 12:1. Obviously, the lower snow ratio end,
if it is all in the form of snow, would be a very wet snow.
Currently we are indicating a mix of rain and snow during the day in
the valleys locations in this region, which is why snow ratios are
even lower at times. Looking at forecast soundings in this area,
while strong upward motion will likely be co-located with the snow
growth zone, it will be located more than 10,000 feet above ground
while a nearly isothermal and relatively warm layer exists close to
the surface. Depending on how warm the boundary layer gets, it is
reasonable to expect snow character to indeed transition from
average to wet by Saturday morning. However, there then will be a
period of time late in the event that snow character should trend
drier, and the model spread greatly decreases Saturday evening with
a 10:1 or higher snow ratio favored. The question is how much liquid
will be fall in the wetter snow. Hopefully we can answer that
question as we get closer to the event to help predict snow load
impacts.

Over what time period? I'm just going back to 2009 when we moved back to maine

Seems unlikely that he's had ten years under 24 inches. The official records at Portland, which date to 1881, show the lowest annual total at 27.5 inches.

Corrected that from earlier.  Yes, my total for PWM this year is #1 currently.

Let’s get this more south. I’d rather clear 15” all snow rather than 8” with R/ZR on top.

Now that I see where we're at for futility, let's keep it north and under 2.8" here.

A foot here would put me within range of getting near average if we have a decent April

I'm at 40.2" on the season, 75" is avg, Don't think we will get there but 2015-16 was 50.1" worst in at least the last 25 yrs may have a shot.

I’m at 46” maybe an outside shot at 60” which would be little less than 75% climo. So maybe a C- winter is still in reach

At this point, I'd rather just see rain, I'm not even going to get close to climo avg, If the Nam is right, Its going to be rain.

What a frustrating pattern. Instead of developing a nice low to the south, this whole thing just presses SE and kicks it OTS. This effing season can end now. 

April snow

Have to believe

Yeah this was super close to being a nuke....but just enough northern stream nuances to screw it up again.
