And that's what I love about up here.  Yeah, it would be great to get a big synoptic event with a high water content to put down a solid base on the natural trails, but it seems like up here, with every threat comes the potential for that backside cold shot bringing the up-slope.  I forgot which one of you reminded me, the northern greens don't move, so when that upper level pattern can be forecast several days out, we can have more confidence in getting some decent snows, rather than living and dying with each model run.  I may be different that some folks who just love the big event that you track for days with the highs and lows of 1 am model runs, but I'll take the consistent powder days all winter long over the blockbuster.  Hopefully, that gfs run that shows a few days of up-slope magic and below freezing highs gets some terrain open next week.  We saw some on and off mixed precip yesterday, but nothing but grass outside right now.

 

Seems like the greens always get good right-side up snowfalls due to this.  The synoptic event brings the denser low-ratio snow, or rain, with warmer temps and then the storm will transition to the low-density stuff as the upslope kicks in.  I've noticed with a base, a 6 inch snowfall can ski a lot deeper just due to the gentle shift between dense and fluffy snow.  Even on events that begin with rain, this seems to occur more often than not.  Otherwise you get a rain crust, which sucks, but likely helps hold the pack for longer.

LOL yeah guess I should have actually captured the moon in the shot. Was trying to show how bright it was. 

I'm just kidding.  Hart's Location is a tiny town (settlement?) with something like 50 people in Crawford notch.  The picture does show how bright it was outside.

lol at that Peter Sinks site. They mixed out overnight and went from -28F to the mid 20s in under an hour.

Wunderground doing a nice job of showing the classic Bennington country downslope zone on the estimated precip. 

Just checked my gauge and its .65"

So peeking at PWS precip amounts, looks like most eastern slopes spots are .70-.95" then slides down to .65" at my place on the immediate western slopes, the fades off to .25-.50" a heading west a few miles from the spine.   Definitely been gusty, but considering how many high wind events there are here, pretty meh overall.

It would be incredible to feel that change in an hour at some point in my life, ha.  It's hard to mentally process a 50-degree swing in 45 minutes.

Up to 2.30" and still pouring out. Easily my biggest calendar day rainfall since moving here at the beginning of August.

Even over here my Stratus is overflowing so it's 1"+.  Models didn't have anywhere near this amount of rain here.

This was just the 12z EURO showing about 0.60" here through 11pm/4z.  We will at least double that.

The 12z GFS was even worse.... like 0.30-0.40" through 11pm.  The local PWS are at 0.30/hr right now lol.

Huge fail.

The entire east slope of the Greens is solidly 1.00-1.75" so far based on PWS amounts up and down RT 100... Sugarbush area up through Waterbury and into Stowe.  I mean that's a pretty massive QPF bust going on it seems.

Yard is like a swamp.  Not really stoked on vastly over-performing rain right now.  Mountain must be taking a beating.

Flash flood warning issued with the expectation of another 1-2" of rain. I'm measuring 2.42" now. Up to 54 degrees.

Makes sense.  This has been alarmingly efficient at raining.  Looks like you guys up through Phin's area is about to get into another firehose shortly. 

And you know it's likely seeder feeder raining harder than radar shows in the mountains and upslope wind flow.
