Nice! Usually there is a noticible difference in snow depth between here and Williston/Burlington, not right now though. Nice that you can see Vermont at it's finest during your visit. :snowing:

Thank you and yes I picked the right time! I plan on skiing Smuggler's notch on Tuesday before headed back home.

Ripton, VT the big winner around with 15".

Pretty classic blocked flow event... good call with the Froude numbers being so low.

West side of Mansfield looks sweet on the Underhill web cam and folks skiing the Teardrop trail are reporting a foot of fluff. This side of the mountain I've only got 4" at 1,500ft and 6" at 3,000ft. The flakes have been so small...its like pixie dust. This stuff has been battling dry air and downslope the whole time.

Its not often the BTV NWS gets 10-11" while my 3,000ft snow board gets 6". BTV's beaten us in the past 2 events at my 1,500ft and 750ft measuring locations.

I will say this event took 3,000ft over 100" cumulative on the season...with 101" as of 12pm today. That does not include October snowfall, though. Snow depth is 42 inches at 3K and a wind-packed 18" at 1,500ft. The hardwoods at 1,500ft are not nearly as effective at blocking the strong winds ripping out of the Notch as the evergreens at 3,000ft.

Event totals: 7.8” Snow/0.35” L.E.

The last round of upslope snow this morning was incredibly dry, and I stacked 3 cores in my analysis to get a good sampling. The snow/water ratio in the report below comes in high because of rounding to two decimal places in the liquid content before Excel does the calculation, so it’s more like 60 to 1, but in any event, it’s very dry. It’s settling so fast that the stake has a lower reading than it did at 7:00 A.M. this morning, before the addition of this latest snow.

Details from the 1:00 P.M. Waterbury observations:

New Snow: 1.9 inches

New Liquid: 0.02 inches

Snow/Water Ratio: 95.0

Snow Density: 1.1% H2O

Temperature: 19.4 F

Sky: Partly Cloudy/Flurries

Snow at the stake: 17.5 inches

Yeah, Around 900mb is was a little toasty for a time, That is always the fear when you see that being modeled, It can't be ignored although some do

Many did and were all surprised and whatnot to see RA/IP for a time. I wasn't surprised at all, but the weenie inside was very upset haha.

So how would you classify yesterday's event? The SNE and NNE (or at least VT) events almost seem like they were separate. Does that make sense or am I completely off base?

Wow... west slopes got bombed today.

Bolton with another 10"... Smuggs with 12"... Underhill State Park with 12"

Low inversion level meant we only picked up around 1" today as none of that moisture was able to make it over Mansfield. Photos look like it was huge flakes on the other side, while we had very small pixie dust. Snow growth zone must be real low, too...that stuff was probably forming at like 2-5,000ft in the atmosphere. It was snowing pretty good this morning with the moon showing...there were no clouds above like 4-5,000ft yet 10-12" of snow fell on the west side, lol. That stuff fascinates me.

Video from the surprise this morning:

Man that is awesome. Didn't see anything like that on the east slope of the Spine.

Those flakes are freakin' huge. That's the definition of good snow growth, lol.

That reminds me a lot of the January 1-3, 2010 event in the Champlain Valley. I was in Burlington at the girlfriend's for that event and I remember waking up to it just pouring palm sized dendrites. That's how you get some huge accumulation numbers real fast. That type of snow was stationary for a long time in that 2010 orographic blocking event, and led to the record 33.1" at KBTV.

If you have a moment, as a meteorologist you may find this very interesting as last night and this morning was very similar in at least the low inversion and blocking mechanism:

It would be sweet to have you up here all winter with the obs and discussion. We are always welcoming and looking for more NNE posters.

You're right. NNE (outside of ME) was a combo of the primary low ad WAA snow. SNE was a little bit of over running snow with most coming with that bombing low. I had 3"/hr rates. I received 9.5" from 4pm to 10pm. Crazy stuff. I've never seen it that heavy in VT. EVER. I'm sure it is over near PF but not in my snow hole that I call home up there lol

Yeah the NEK is known for snowpack retention and cold temps. They don't usually get the high rate snowfall.

We'll usually get that sort of stuff once a season from an upslope event...of course with synoptic storms, its all just luck and being in the right place at the right time.

I think its important though to note, that getting 3"/hr rates in synoptic snow is much harder, and usually more impressive (like Valentines Day up here when BTV got 12" in 5 hours) than with meso-scale snow.

Last year's February 25 upslope event was the last time I had 3" per hour snowfall... but its pretty easy to accomplish when snow growth is so maximized (ie, 3"/hr but under 0.1"/hr qpf).

And this photo from that event is from the Stowe Medical Center down in town. We were getting around 2"/hr in this down in town, but visibility wasn't all that restricted. Its just that the flakes are so freakin' huge that it does this for a couple hours and all the sudden you have another 3-4". To get the higher rates in synoptic snow, the visibility is often much less.

7.5" storm total snow. Quite the storm! I had a period of time where I was getting 2" an hour rates. Looking forward to the deep cold to keep the snowpack.

From the side yard at home.

I have always thought that for most of VT, or at least my area, we get most of our snow from multiple small and medium events and rarely get the large jackpots like they do closer to the coast. There are winters when it just snows with what seems like very little provocation and it seems like we'll get a couple of 2"-4" or 3"-6" events per week punctuated by an 8"-12" type a few times. And as PF noted, snow retention is great in large parts of the state.

Saw some serious wind on Mansfield today with wind chills of 30 below zero.

Highest gust today was 92mph and highest sustained wind was 67mph. I'd love to know what the primary NWS station reported up there.

Chairlifts ran in this stuff, too...just like they ran in the 125mph wind gust a couple weeks ago. Wind holds have been pretty much non-existent this season even though we've seen some pretty crazy wind speeds.

Bolton had a wind hold this afternoon on one of the lifts..we were snowshoeing over there and it was rather calm in the woods

Got down to 9F pretty quick but has stayed right there for the last couple of hours. Winds picked up a bit and will keep us from going much lower unless it calms.

I see that BTV updated the storm total snowfall map since the last posting in this thread, so I’ve added it below along with the various numbers. In line with the blocked flow, on the updated map you can really see how the darker blue accumulations are able to sneak through the mountains via the Winooski Valley/I-89/Route 2 corridor – very cool stuff. They must have used this thread to grab that last 1.9” I recorded as of 1:00 P.M., because I haven’t sent that in to CoCoRaHS yet; this is the only place I posted the data. It’s great to see that the data in the thread are being used.

Depending on what you're looking for in a town, Woodbury, parts of East Montpelier, Calais and Worcester are great in Washington. In Lamoille, Elmore, Wolcott, parts of Morristown and Hyde Park are what I'm most familiar with. Of course there is Stowe and Waterbury but I prefer a bit further north.

Thanks, mreaves. I work from home, but I do need broadband access, so I guess that limits me a bit. I'm tired of paying the expensive property tax rate in Montpelier proper, so I have no problem moving out of the city. Maybe a condo up at Bolton Valley? Wouldn't mind being above 2k'! I'm six years divorced, 50 years old, holding down a five bedroom house and I enjoy my solitude. Time to downsize and live my way!

I notice a lot of times Montpelier isn't reported in the snow totals. You'd think being the capital city of the state there would be a dedicated report for all storms. Anyway...ended up with 3.5" at 880' after all was said and done.

I was surprised to look out when I let the dog out this morning and see it snowing big fat fluffy flakes. There was only a tenth or so on my car so it must've started not long before 4:30am.

There's about a half inch of new snow overnight here at 1,500ft, which with yesterday's snow makes 1.4" in the past 24 hours at 1,500ft on the east slope. Significantly less than what the west slope got...but ya win some and lose some.

I would imagine those west slope communities are picking up more fluff this morning from the radar.

Looks like there is a dusting out on my car. Oh well it covers up the yellow snow spots out back.
