Synoptically it does make more sense.  Coldest anomalies are pressing into the upper Midwest and upper Lakes in the means...baroclinic zone definitely favors an inland runner, IMO.  

I could also see it being very close to the Friday/night system.  ULL is held pretty far NW.

I said that the other day given the pattern...that was after Kevin said "there is no cutter next week."  That happens when cold dives south, but again, it's a decent look. No one eyed pig is always good.

lol not a clue... was in high school in NY.   I'll do some digging.

It was a high elevation snowfall, above 2,000' in Central Vermont. I skied Killington Thanksgiving Weekend and Killington had over 60 opened trails. It got warm and melted away shortly after. I recall about 24" of snow fell from the storm at Killington and it was very wet snow.

I remember watching TWC that evening during the storm and the OCM was losing his sh1t because MPV had flipped back over to 33F S+.

I was 20 years old but had made the 18 year old drinking age cutoff 2 years earlier. Pretty sure I was liquored up in some bar with everyone else who was home for the holiday. Don’t remember snow.

Everything I can see on NOWdata seems to suggest a decent QPF event but not a ton of snow, even at Mansfield and Jay Peak.

Interesting that MPV flipped to SN+ as the ASOS records show 0.67" precip but temp spread of 37/34.  Must've gone to just a very wet snow at 34F or something.

There must've been one helluva QPF gradient though given the BTV total compared to the mountains and east.  These are two-day totals around that time period:

BTV... 0.20" precip, no snow.

Eden (1,500ft between Mansfield and Jay)... 1.03" precip, 1.5" snow

Morrisville (COOP not ASOS)... 0.78" precip, 0.7" snow

Rochester (just north of Killington)... 1.13" precip, 2.0" snow.

Woodstock (east of Killington)... 1.65" precip, 0.0" snow.

Bethel (northeast of Killington)... 1.62" precip, 1.0" snow.

 

The mountains had significantly more precip, as the only two COOPs above 2" liquid:

Jay Peak... 2.06" precip, 6.5" snow, depth increase of 7" (to 7")

Mansfield... 2.15" precip, 8.5" snow, depth increase of 8" (to 21")

*The Mansfield snow data is interesting as the high temperature for the storm was 30F but the snowfall and depth increase are pretty similar.  Wonder if there was freezing rain or sleet mixed in there?  It's not uncommon to see the new snow under-reported at the COOP there but in those cases you'll usually see the change in depth be significantly more than the reported snowfall.

There was close to nothing for snowfall accumulation below 2'000 - 2'500'. I also skied at Okemo that weekend and only the top 2/3 of the mountain had snowcover.

It was all dynamic cooling so there would be haves and have nots depending where the strongest uvv’s were. It was back to the upper 30s around midnght with rain.

Looks like only moderate there though. 

Interesting.  I was in NOWdata for Montpelier-Barre and assumed it was the ASOS.  But those hourly obs show differently.  

Either way, moderate snow in that marginal thermal profile is usually pounding snow.  That's wet pasty or slushy dendrites falling furiously.  Given the surrounding snowfall reports that's like the stuff that brings 1" snow on .30-.40" QPF slop.

Bears out my memory of skiing glue. There was also almost no snowmaking base due to the warm November. Wasn't 1998 and El Nino year? That winter was very warm.

Yeah must've been heavy wet stuff... and even the higher elevation snowfall was dense on the numbers...high QPF but low ratio snowfall even at temps near or below freezing.  1,500ft and below temps looked very dependent on lift, and locally those snow levels can vary drastically based on orographics and banding in Vermont.

It was a coastal storm that had to manufacture it's cold air, almost like a late October snowstorm rather than late November.

How much snow did you get up there on Thanksgiving 1998?

Looking back, Thanksgiving itself was on the 26th, and I’ve got reports from my ski journal on the 26th, 27th, 28th, and 29th (links below).  The reports are generally ski focused vs. weather focused, but there’s definitely plenty of snow/weather stuff in there.

I went skiing on the morning of the 26th before Thanksgiving dinner and I’ve added an excerpt of that text below.

“This morning I was off to Sugarbush for some Turkey day turns.  Mt. Ellen (Sugarbush North) is now open, so I figured I'd hit it for the first time this year.  As I left Burlington, conditions were drizzle/light rain (40 degrees F), and I was anticipating drizzle and maybe a few flurries at the summit, but I wasn't expecting and real snow, shows to go ya what I know.  As I entered the more mountainous areas of Richmond along I-89, the rain became steadier and it was an all-out downpour at times.  I was just dreaming of what conditions would be like if it were cold enough for snow.  I figured we had overrunning warm air, and even the mountains were warm enough for rain, oh well, skiing is skiing, I'll take what I can get.

Things began to get interesting as I passed over the mountains on Rt. 100 in Duxbury.  As I reached the pass, I suddenly saw snow mixing in with the rain!  I checked that altimeter, 870', I was just hoping this wasn't a localized sort of thing.  As I crested the top of the road through Duxbury (approximately 1130') the snow was actually sticking on logs etc. in the woods, and as I approached the intersection of 100 and 100B, I noticed a car approach with about 3 inches of snow on it.  Now I was worried that I didn't have my snow tires on yet, I wasn't expecting real snow.  The snow turned back to rain as I passed through the Mad River Valley, and changed back to snow again on German Flats Road (at elevation 930').  By the time I got to the base of the mountain (approximately 1500'), it was starting to accumulate on the road into slush.

I took the lift to nowhere, then onto the North Ridge express and cruised Upper Looking Good / Lower Rim Run to get to the summit quad.  2-3 inches of snow had already accumulated on the sides of the trail, traffic was light, and man was it sweet.”

 

Skiing on the 27th I reported the following:

“It was still too early to get on the Gate House Lift, so I headed over to The Super Bravo. First trip up Heaven's Gate, I see a tele ski patroller ripping a great line down the totally fresh Spillsville.  About a half a foot of new, plus whatever else was underneath, it looked sweet!”

 

The skiing must have been pretty nice on the 28th because I had the following in my report:

“Many new trails are open now, including Paradise, Ripcord, Domino Chute, Lower Jester etc.  basically a good chunk of the stuff that will get you back to Heaven's Gate via the traverse.  I also overheard that they opened Exterminator.  In general, as people have mentioned, the coverage on the natural snow trails (that are open) is great.  Paradise was awesome, except for the connection section back to Ripcord which had a lot of exposed rocks.  Get out and enjoy some of the soft natural, it wasn't even turning hard under the traffic of Holiday weekend skiers.”

There must've been one helluva QPF gradient though given the BTV total compared to the mountains and east.  These are two-day totals around that time period:

BTV... 0.20" precip, no snow.

Eden (1,500ft between Mansfield and Jay)... 1.03" precip, 1.5" snow

Rochester (just north of Killington)... 1.13" precip, 2.0" snow.

Woodstock (east of Killington)... 1.65" precip, 0.0" snow.

Bethel (northeast of Killington)... 1.62" precip, 1.0" snow.

 

The mountains had significantly more precip, as the only two COOPs above 2" liquid:

Jay Peak... 2.06" precip, 6.5" snow, depth increase of 7" (to 7")

Mansfield... 2.15" precip, 8.5" snow, depth increase of 8" (to 21")

*The Mansfield snow data is interesting as the high temperature for the storm was 30F but the snowfall and depth increase are pretty similar.  Wonder if there was freezing rain or sleet mixed in there?  It's not uncommon to see the new snow under-reported at the COOP there but in those cases you'll usually see the change in depth be significantly more than the reported snowfall.

Edit: Wait a second, I just noticed you were talking about 1998 not 1988. 10 years later was probably just a better beer.

“It was still too early to get on the Gate House Lift, so I headed over to The Super Bravo. First trip up Heaven's Gate, I see a tele ski patroller ripping a great line down the totally fresh Spillsville.  About a half a foot of new, plus whatever else was underneath, it looked sweet!”

 

The skiing must have been pretty nice on the 28th because I had the following in my report:

“Many new trails are open now, including Paradise, Ripcord, Domino Chute, Lower Jester etc.  basically a good chunk of the stuff that will get you back to Heaven's Gate via the traverse.  I also overheard that they opened Exterminator.  In general, as people have mentioned, the coverage on the natural snow trails (that are open) is great.  Paradise was awesome, except for the connection section back to Ripcord which had a lot of exposed rocks.  Get out and enjoy some of the soft natural, it wasn't even turning hard under the traffic of Holiday weekend skiers.”

I remember that it was too warm for Okemo to make snow on the lower mountain. We had to take a shuttle bus up the mountain to the Green Ridge Triple Chair.
