in case folks missed the BTV area discussion earlier:

https://forecast.weather.gov/product.php?site=BTV&issuedby=BTV&product=AFD&format=CI&version=1&glossary=1

Sfc analysis places powerful and deepening 985mb low pres near Ely
MN, while a 1030mb high pres is acrs the north Atlantic. Upper air
analysis shows sharpening full latitude mid/upper lvl trof acrs the
central Plains, while deep moisture advection continues on a
strengthening south to southwest flow in the 925mb to 500mb layer.
As sfc low pres deepens the 925mb to 850mb wind fields strengthens
overnight into Friday acrs our region. The NAM and RAP both show
progged 850mb winds of 75 to 90 knots, while 925mb winds are in the
55 to 70 knot range, highest over the northern Dacks into the
northern CPV. The difficult challenge continues to be how much
mixing occurs, as the strongest winds are co-located with the axis
of heaviest rainfall. However, given the progged fine line of
convective showers by NAM3KM/HRRR, the embedded heavier down
pours would have the potential to tap very strong winds in the
925mb to 850mb layer and transfer some higher speeds to the sfc.
Given this potential and latest RAP/HRRR soundings showing 500
foot agl winds of 45 to 55 knots, with 59 knots at Malone at
12z Friday, we have expanded the wind advisory. HREF shows 60
to 80% prob of 60 mph or greater winds along the Route 11
corridor and acrs parts of central/northern VT with <30% prob of
winds greater than 65 mph, while indicating 90 to 100% of winds
>45 mph acrs most of our cwa. Did consider High Wind Warning
for northern Dacks, but southeast direction and still some
uncertainty on boundary layer mixing, may limit areal coverage
of 60 mph wind gusts. Still something to watch closely. Also,
have some concerns over southern Greens with southeast downslope
gusts near Rutland, but soundings are showing slightly weaker
low level wind fields and limited mixing due to the moist
adiabatic sounding profile and weak inversion above ridgetop.
Generally thinking wind gusts in the 45 to 55 mph range, which
wl peak between 4 AM and Noon on Friday.

We’ll see, but I’ll take the under.  Which is easy to do in the valley anyway.  
I hope Kevin can rip some 50-60 mph. 

Always take the under. The best winds are always from some unhyped front coming through.

what in the sam hell. What boundary layer physics/equations are used by the HRDPS? That looks like its mixing down 100% of 925mb lmao. Does it think 10m is 925mb

I don’t mean to be a pretentious ass, but I’ve read “Sam hell” on these forums 50 times over the years, but there is no such expression. It’s Sam Hill. Sorry.

That may be the saying but Hill is still supposed to mean 'hell'. so who cares

The only time winds materialized for me, as forecast or greater, was on 12/23/2022- two weeks before my house generator was installed.  Lost 3 solid trees, roof shingles/flashing (roof needed to be replaced anyway). Also stupidly left a chair on the back deck which took out 12 spindles on my railing.  Power out for three days (right up through Christmas Day), as temperatures had crashed into the single digits.  I do not want to experience that again.

Xmas 2020 was pretty epic. We lost power Xmas morning. 

Ya, see those didn’t do that much here, no power loss. The 12/23/22 that was the warm rain(blizzard in Buffalo), then temps crashed. But again, no power loss.  But I get it…out east it was different.
