Area Forecast Discussion
National Weather Service Burlington VT
627 AM EST Tue Nov 28 2017

.SYNOPSIS...
Windy and warmer today with temperatures climbing into the 30s
and 40s with breezy south winds at 15 to 30 mph. Mild
temperatures continue overnight with readings mainly in the
30s...before a cold front sweeps across the North Country on
Wednesday. This will produce some mountain rain and snow showers
along with falling afternoon temperatures. Only minor snow
accumulations expected.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
As of 612 AM EST Tuesday...Minor update to capture latest
trends...which features warming temps and increasing sfc
winds/clouds from cpv and points west. Meanwhile...light winds 
and mainly high clouds east of the mtns continue to support 
temps around 0f NEK to lower teens. Temps will quickly warm once
winds develop and capturing rate of rise will be difficult this
morning...along with winds. According to hourly obs SLK was down
to -3F earlier this morning with BTV 15F and many locations in
the single digits. Making for the coldest low temps of the early
winter season, lets hope this trend continues along with
frequent upslope snow events of the past couple of days and
several larger cold synoptic systems to help build snow pack.
Okay I will stop dreaming about perfect early season conditions
and get back to work. 

The forecast challenge is wind and temps...as strong southerly 
flow develops. Water vapor shows building ridge across the MS/OH
valleys...while mid/upper level trof lifts out of the ne conus.
The combination of departing 1030mb high pres and approaching 
sfc trof associated with 982mb low pres near Hudson Bay will 
produce a strong llvl wind field over the fa. NAM 3km and local 
btv 4km shows 925mb to 850mb winds increasing to 55 to 65 knots 
across the SLV/Northern Dacks btwn 18z-03z today. 
However...soundings continue to support max bottom of the mixed 
layer winds of 30 to 35 knots...resulting in sfc wind gusts btwn
30 and 40 mph over the slv and parts of the northern/central 
CPV...especially over the warmer lake waters. Over 
central/eastern VT llvl profiles show limited mixing...as temps 
struggle into the l/m 30s...so not anticipating any gusts in the
deeper valleys. Mountain summits gust btwn 55 and 70 mph by 
late this aftn/evening hours associated with potent llvl wind 
field. The combination of strong 925mb to 850mb thermal 
advection and increasing clouds makes for a challenging temp 
forecast this aftn...especially after such a cold start. 
Thinking we warm almost 50 degrees at slk today...from early 
morning lows near -5F to an afternoon high in the mid/upper 40s.
Elsewhere...similar large swings in temps anticipated with 
upper 40s/lower 50s expected slv/western dacks to mid 40s cpv to
mid 30s eastern VT/NEK.

Tonight...temps continue to present challenges as deeper valleys
east of the Green Mountains will probably decouple and fall into
the mid/upper 20s. Meanwhile...llvls remain mixed in the cpv/slv
with lows holding steady in the upper 30s to mid 40s...under
breezy southerly winds. Best moisture/dynamics with approaching
sfc boundary and associated 5h vort stay mainly to our
northwest...so a dry forecast is expected. 

On Weds...guidance in good agreement with placement of sfc cold
front across the SLV at 12z...along with enhanced ribbon of 850
to 500 mb moisture and weak 850 to 700mb uvv couplet. This llvl
convergence and mid level moisture will produce a small 1 to 3
hour window of scattered valley rain and mountain snow showers
on Weds. Initially progged 850mb temps are btwn 3-5c supporting
snow levels above summit levels...however as precip arrives wet
bulb cooling quickly lowers progged 850mb temps btwn -1c and -3c
by 12z Weds. This results in snow levels lowering btwn 3500 and
4000 feet by 12z Weds...and btwn 2000 and 2500 feet by 18z Weds
as 925mb temps drop btwn -1c and -3c. Have tried integrate this
idea into the grids with some minor snow accumulation likely in
the dacks and northern/central green mountains on Weds.
However...overall qpf will be light generally btwn 0.10 and 0.20
in the mountains...with snow ratios of 10/12 to 1...so a dusting
to several inches from base to summits. Will mention likely pops
in the mountains and schc/chc in valleys with llvl wind fields
impacting qpf/pops. Temps start warm in the mid/upper 30s to mid
40s...but fall during the afternoon hours back into the upper
20s to mid 30s depending upon location and elevation.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY/...
As of 427 AM EST Tuesday...The short term will be rather quiet 
overall as Wednesday night will see high pressure build in the 
from the west into Thursday for dry weather and temperatures a 
few degrees above normal as high is building in from the west 
versus the northwest. This dry break will be short lived as the 
high pressure ridge begins to shift to the east Thursday evening
and the next round of precipitation comes in association to a 
short wave through from the west.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
As of 427 AM EST Tuesday...Upper trough moves into the region 
overnight Thursday into Friday, bringing with it rain and snow 
showers through Friday evening. As few snow showers may linger 
in NEK Friday night into Saturday morning as the upper trough 
exits the area before the next round of high pressure settles in
during the day Saturday. Beyond this point, the next chance for
any significant precipitation won't come until the middle of 
next week, though models can agree on which day exactly it will 
be. Overall, expect temperatures to be mild for this time of 
year with highs in the upper 30s to low 40s and lows in the 
upper 20s to lower 30s, all slightly above average for early 
Dec.

&&

.AVIATION /11Z TUESDAY THROUGH SATURDAY/...
Through 12Z Wednesday...VFR conditions prevail thru 06z
tonight...before lower clouds and potential mvfr cigs develop at
slk by 12z Weds ahead of approaching boundary. The big impact 
to aviation today will be developing 925mb to 850mb southwest 
jet of 50 to 60 knots...creating localized sfc gusts btwn 30 and
35 knots at slk/mss/btv...along with areas wind shear and 
turbulence. Expect some moderate to locally severe turbulence in
and around trrn features today...with increasing mid/upper 
level clouds. Weak surface boundary will increase low level
clouds toward 12z weds...with a few scattered rain showers and
trrn becoming obscured. 

Outlook...

Wednesday: VFR. Chance SHRA.
Wednesday Night: VFR. NO SIG WX.
Thursday: VFR. NO SIG WX.
Thursday Night: Mainly MVFR, with areas VFR possible. Likely
SHSN, Likely SHRA.
Friday: Mainly MVFR, with local IFR possible. Chance SHRA, Chance
SHSN.
Friday Night: Mainly VFR, with areas MVFR possible. Slight chance
SHSN.
Saturday: VFR. NO SIG WX.

&&

.MARINE...
A lake wind advisory is in effect for developing south winds 15
to 25 knots this morning, increasing to 25 to 35 knots this
afternoon with gusts to 40 knots possible. Waves build 3 to 6
feet. Winds continue overnight at 20 to 30 knots from the south
before shifting to the northwest on Weds and decreasing.

&&

.BTV WATCHES/WARNINGS/ADVISORIES...
VT...None.
NY...None.
