Area Forecast Discussion
National Weather Service Burlington VT
351 AM EDT Sun Aug 30 2020
.SYNOPSIS...
Gusty northwest winds and cooler temperatures are on tap for
the North Country on Sunday along with the potential for a few
mountain rain showers. Highs pressure builds in Sunday night
and Monday bringing dry weather and slightly below normal
temperatures. Mid weeks brings a warmer and more unsettled
pattern, however cooler and drier weather returns by next
weekend.
&&
.NEAR TERM /THROUGH MONDAY/...
As of 348 AM EDT Sunday...Cloudy, cool day expected across the North
Country as upper level trough remains overhead. A few isolated to
scattered showers are possible this morning as vort max rounds the
bottom of the trough and last sfc boundary associated with this
system moves though. Westerly flow will turn out of the NW behind
this font and begin ushering cooler and dry air. Highs today will
continue to remain below normal in the mid to upper 60s. Clouds and
chances for any precipitation diminish as the afternoon wears on as
heights aloft begin rising and subsidence behind front settles in
overhead. A chilly night is expected with clearing skies and light
winds. Overnight lows will be 10 to 15 degrees below average
generally in the low to mid 40s, although a few spot readings in the
mid/upper 30s is certainly possible in the most protected valleys
across the Adirondacks and the NEK. Given good radiation conditions,
valley fog is expected in the typical locations. Temperatures begin
to moderate Monday with sunny and dry conditions as flow begins to
turn out of the southwest.
&&
.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/...
As of 348 AM EDT Sunday...Relatively quiet short-term period expected
as surface ridging translates ewd across the Gulf of Maine into the
Canadian Maritimes. Looking for development of a light S-SE return
flow Monday night into Tuesday morning. This will keep temperatures
generally 5-10F warmer Monday night as compared to Sunday night,
with lows mainly 50- 55F, except 45-50F across the Adirondacks and
far nern VT. There is a decaying shortwave trough in southwesterly
700-500mb flow that translates newd across nrn NY and VT during the
day Tuesday. Given absence of low-level convergence, this feature
should generally bring only variable mid-level cloudiness during the
day Tuesday. Kept PoPs generally 15-20% range. It does appear that
southerly gradient flow strengthens a bit further by Tuesday
afternoon. Winds should increase to 10-15 mph, with gusts 20-25 mph
possible particularly with channeled flow in the Champlain Valley.
With 850mb temperatures moderating a bit further (+11C to +12C by
mid aftn), highs on Tuesday are expected to reach the mid-upper 70s
in most valley locations.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Lots of variability in 00Z NWP guidance suite during the extended
forecast period, largely a function of active northern stream from
the Dakotas ewd across the Great Lakes into NY/northern New England.
Two shortwave troughs are the main focus of the extended period,
bringing potential precipitation periods Wednesday aftn/night and a
second Thursday night and perhaps into early Friday before trending
cooler/drier. Appears initial mid-level shortwave trough shears out
to our north and west in both the 00Z ECMWF/GFS solns, such that as
attendant cold front approaches, it generally weakens as it moves
into the North Country Wednesday afternoon into Wednesday night.
Tried to indicate this with best chances for precipitation across
nrn NY Wednesday afternoon (60-70% PoPs), but only reaching 40-50%
across VT during the overnight hours as support for UVV aloft
weakens as system translates ewd. Should see valley highs in the mid-
upper 70s across the North Country. Minimal CAPE and with weaker
forcing, chose to leave out any mention of thunderstorms attm for
Wednesday.
Question on Thursday will be whether or not surface front clears our
area to the south, or if it dissipates in place in the absence of
any height falls Wednesday night into Thursday. Went with the latter
idea for now, allowing temperatures to reach near 80F on Thursday in
the warmer valley locations. Kept a slight chance of showers
(roughly 20% PoPs) attm for the daylight hours Thursday.
NWP guidance diverges a bit more strongly Thursday night into
Friday. The 00Z ECMWF is a bit faster and more pronounced with the
next cold front Thursday night, with potential widespread shower
activity. This soln also has support from the 00Z Canadian/GEM. The
00Z GFS is less robust and slower, with lower precipitation chances.
For now, Indicated 30-40% PoPs Thursday night, with cooler and drier
conditions Friday afternoon through Saturday. Should see high
temperatures trend downward from the mid-upper 70s on Friday into
the lower 70s for Saturday.
&&
.AVIATION /08Z SUNDAY THROUGH THURSDAY/...
Through 06z Monday...Ceilings and visibilities will generally
be MVFR/VFR overnight as satellite imagery shows ample cloud
cover across the airspace. Ceilings will lift to VFR at all
terminals after 12z as breezy NW winds kick in. Expect winds to
remain 10-15 kt with gusts 20-25 kt range through 00z Monday.
After 00z, winds decouple with light and variable winds expected
across the area.
Outlook...
Monday: VFR. NO SIG WX.
Monday Night: VFR. NO SIG WX.
Tuesday: VFR. Chance SHRA.
Tuesday Night: Mainly VFR, with local MVFR possible. Chance SHRA.
Wednesday: Mainly VFR, with areas MVFR possible. Likely SHRA.
Wednesday Night: Mainly MVFR, with local IFR possible. Chance
SHRA.
Thursday: Mainly VFR, with local IFR possible. Chance SHRA,
Slight chance TSRA.
&&
.MARINE...
A Lake Wind Advisory remains in effect through the remainder of
today as westerly, becoming northwesterly winds 15 to 25 knots
continue. This will create choppy conditions, especially over
the southern half of the lake.
&&
.BTV WATCHES/WARNINGS/ADVISORIES...
VT...None.
NY...None.
