NNE Cold Season Thread 2025-2026

[Boston Bulldog]

Snow is back in the forecast for the Green Mountain spine, and the BTV AFD is asking the questions we are all thinking... it appears as though cold season is nearly upon us! Looking forward to the incoming stake photos tomorrow morning, may this winter be as cold as the last!

.SYNOPSIS...
Cool and blustery conditions will prevail for most of this upcoming
weekend with occasional valley rain and mountain snow showers. A
light slushy snow accumulation is possible above 1500 feet by
Saturday morning, as temperatures fall into the upper 20s to near
40. Westerly winds will gust at 30 to 45 mph at times overnight,
before slowly weakening on Saturday. Warmer and drier weather
returns by early next week, as temperatures climb back into the 50s.

&&

.NEAR TERM /THROUGH SATURDAY/...
As of 247 PM EDT Friday...Updated to remove equipment section as
TYX radar is back in service.

A cool, blustery and showery evening is on tap for Halloween
activities. Sfc analysis places an impressive 978mb low pres
just east of Sherbrooke with deep/vertically stacked system
slowly moving northeast. Storm total rainfall has been 1.72"
here at BTV thru 2:45 PM, just imagine if it were colder. This
closed cyclonic circulation wl produce a prolonged upslope
precip event acrs our mtns thru at least Sat morning, before
drier air develops by Sat aftn and precip slowly dissipates. The
highest pops near 100% and greatest qpf wl be focused over the
northern Dacks and central-northern Greens, with much less in
favorable downslope areas of the CT River Valley and parts of
the western CPV.

Whiteface summit temp already down to 30F with flakes flying
and little Whiteface at 3000 feet is 33F, would expect snow
level near SLK/Lake Placid by 00z, as progged 925mb temps fall
below 0C. For the Green, snow levels start near summit level
this aftn, but falls to 3000 feet by 00z and near 1500 feet
around midnight. 925mb temps hover btwn -1C and -3C, so a slushy
snow accumulation is possible on grassy surfaces down to 1500
feet or so by morning. Expecting 1 to 3 inches btwn 1800 and
3000 feet, 2 to 4 inches between 3000 and 4000 feet and 4 to 6
inches at summit level of both the Greens and Dacks by Sat aftn.
Will there be enough for the rock skis and boards by midday
Saturday?

Now that Melissa is gone I’ve moved from tropical to late fall mode. With one of my locations now being SLK I’d love to post here too representing the western portion of the BTV NWS area, if y’all will have me.

If only it was colder… it has been pounding precip all afternoon and just keeps going.

Prolific snow maker even into the low lands if like 5C colder today.

You are welcome to post here, but beware. If you post pics of snow while SE Mass is getting rain or has bare ground, @CoastalWx might come for you.

SLK over to -SN.

After hours of white rain and mangled flakes at 3,000ft... it's finally starting to accumulate.  Looks like we have until 4-5am before it tapers off.

My mtn forecast was for 2-5" at that location so we'll see.  I think we can get 2+... 4-5" will be tough on that elevated snowboard.  It's gusting 40-50mph up there and moving more sideways than landing on the platform, too.

My wife reports a car topper. We're on the board, people!

A different world from CT.  A completely different world being at that elevation, but in a valley surrounded by big terrain too.  Elevational snows and radiational cold mins combined.

Well, if the NNE Cold Season thread is back, then we really must be moving into snow season.

I know we had those first snows back about a week ago, but it’s been fun to see some of the comments from the BTV NWS crew as this next event has approached. You could really feel some of the “pro snow” mentality in yesterday’s discussion:

NEAR TERM /THROUGH FRIDAY/...

Trends have been our friend if you are looking for snowfall with changeover occurring in the central/northern Greens btwn 8 PM and 11 PM Friday evening. Snow level look to drop to around 1000 feet by 12z Sat, as progged 925mb temps drop btwn -2C and -3C, while progged 850mb temps are in the -3C to -5C. The ingredients look favorable for a period of upslope rain and snow showers on Friday night with good 850 to 700mb rh >80%, strong 850mb winds of 35 to 45 knots, and moderately strong caa. This wl help to enhance precip with highest pops/qpf acrs the favorable upslope areas of northern Dacks and central/northern Greens. Snow accumulations range from dusting to 2 inches btwn 1000 and 2000 feet and 1 to 3 inches btwn 2000 and 3500 feet and up to 4 or 5 inches above 3500 feet by mid morning Sat. I have tried to highlight this thinking in the latest storm total snow grids. Did utilize the NAM3KM hourly temps in grids to show cooler air moving into the area faster, especially acrs the higher trrn on Friday evening.

SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...

As of 216 PM EDT Thursday...Upslope rain and snow showers wl slowly taper off on Sat with blustery and chilly conditions prevailing. Highs generally in the mid 30s to mid 40s, except only upper 20s summits. Could we see the guns fire atop Killington this weekend? Otherwise a general drying trend is anticipated by Sat night with lows back in the lower 20s to mid 30s.

 

Actually, after a really pleasant stretch of fall through much of September and October, it looks like we’ve had quite a shift in the level of weather activity in this last third of the month. Here at our site there’s been rain on 10 out of the last 12 days, and it pushed us past 5 inches of liquid for October. That’s still a bit below average, but it’s definitely a shift from earlier in the fall. The pattern looks like it continues to be active well into November. If one includes this current storm, a quick run through the GFS and other medium-range models out through mid-month shows 7 to 8 systems coming through the area, and all of them have the potential to offer some snow. It’s not especially cold for November, but those 850 mb temperatures spend plenty of time at or below 32 F. It looks like a lot of systems scooting through in the northern stream, and we know what that means around here.
