Area Forecast Discussion
National Weather Service Burlington VT
338 AM EDT Fri Oct 9 2020
.SYNOPSIS...
Sunny skies and cool temperatures in the 50s today. Then
becoming much warmer on Saturday with showers and a few
thunderstorms possible in the afternoon. A few storms will be
capable of producing strong to locally damaging wind gusts. A
cold frontal passage will send temperatures back into the 50s on
Sunday with drying conditions. Temperatures rebound into the
60s early next week along with renewed chances for rain.
&&
.NEAR TERM /THROUGH SATURDAY/...
As of 330 AM EDT Friday...Tranquil weather expected for today. The
forecast for patchy frost still looks good given most of our
forecast area is in the upper 20s to mid 30s. It'll be one of those
mornings to get out the door a minute or two early to scrap off
the frost from your car, if unsheltered. That's about as
impactful as the weather gets today. Light west to northwest
winds become southwesterly as surface high pressure slides east.
Moderation of the cold air mass in place will allow our
forecast area to warm into the 50s with some sites hitting 60 F.
Towards evening, abundant high clouds should stream across our
forecast area as strong mid- level warming starts to take place.
There could be some virga on radar with the cresting upper
ridge, but mid-level dry air should prevent any activity from
reaching the surface. Clouds should keep low temperatures in the
40s to lower 50s overnight into Saturday morning. Mountain
summits could be warmer than several areas given the strength of
this inversion (~14 C at 4000 ft).
Saturday will be a bit more active. Impressive, but not record-
breaking, October warmth is expected as high temperatures climb into
the lower 70s and dewpoints rise into the mid 50s across our
forecast area. We will see increasing winds aloft with an 850mb jet
increasing to 50 to 55 knots. The good news is that an inversion
aloft should prevent this from efficiently mixing to the surface. It
should still be breezy, especially with channeling south to southwest
winds through the valleys. We will likely look at another Lake Wind
Advisory for Saturday.
For the precipitation chances, we could see a couple rounds of
precipitation. Late morning into the early afternoon, we should see
a tongue of moisture advect into our area along with warm advection
that will produce some showers. It will not be a wash out day, and
the area of showers will likely be narrow. Late afternoon into the
evening hours a potent cold front will cross the International
Border. Warm temperatures and gradual cooling temperatures in the
mid-levels should allow for 250-500 J/kg of CAPE to develop in a
high-shear environment. Better dynamics and vorticity will be to our
north, which means cooling associated with vort will not be timed as
well as occurred Wednesday. However, the distinct wind shift with
this front and the concentrated frontogenetic forcing from the
thermal contrast produced from Saturday afternoon's warming should
allow for a sharp, narrow band of enhanced precipitation with
embedded thunderstorms. This thin band will be capable of producing
strong, gusty winds as it crosses the International Border. The
duration of impacts will not be long owing to its small size.
Thereafter, loss of daytime heating will cause this band to weaken
as the front pushes further south into the Adirondacks and
south-central Vermont. SPC has most of our forecast area in a marginal
risk (Level 1 of 5) outlook for localized (5% chance) damaging wind
gusts up to 60 mph.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 330 AM EDT Friday...The front will continue to push southward
through the region Saturday evening. Drier and colder air will
follow, and this will bring any lingering showers or thunderstorms
to an end by midnight. Clouds will be slower to dissipate,
particularly over the higher terrain, as cold air advection takes
hold. It will be a cold night, particularly in northern sections,
with lows ranging from the mid/upper 30s in the Adirondacks and
Northeast Kingdom to the mid and upper 40s in the Champlain and
lower Connecticut Valleys. Clearing skies are expected for Sunday as
high pressure builds over eastern New England. Winds will diminish
as well, but it will still be a colder-than-normal day with highs
only In the lower to mid 50s in most locations. The high moves
eastward Sunday night, allowing southeast flow to develop. This will
begin to lift moisture back towards the North Country, though it
will remain dry overnight. Lows will be on the chilly side once
again, mainly in the 30s.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 330 AM EDT Friday...The threat for showers returns late Monday
through Tuesday with a cold frontal passage. As has been the case
with the previous fronts, a potent 850mb jet will proceed the actual
passage, making for breezy conditions Monday night into Tuesday.
This system and the associated upper trough swinging through the
Plains will interact with moisture leftover from the remnants of
Hurricane Delta, so anticipate fairly widespread showers during much
of the day Tuesday. The front and upper shortwave sweep through
Tuesday night, and expect at least a short break in the
precipitation for Wednesday. Model solutions diverge thereafter, but
consensus shows deepening low moving up through the Great Lakes
along or just west of the St Lawrence Valley Thursday, which would
bring another round of warmer, windy, and potentially showery
conditions late in the week.
&&
.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
Through 06Z Saturday...Currently VFR at all sites with mid
clouds at 5000-7000ft agl extending southeast near KMSS to KRUT.
These clouds should clear the area around 09Z leaving mostly
clears skies. Patchy frost expected tonight. Winds light and
variable tonight, becoming southwesterly in the afternoon at 5
to 8 knots. High clouds at or above 10000ft begin to stream in
from the west after 21Z. Winds increase at 2000ft agl after
00Z. Southwesterly LLWS at 35 to 45 knots is likely at all TAF
sites by 03Z and continue beyond 06Z as strong area of low
pressure moves east across Canada.
Outlook...
Saturday: Mainly VFR, with local MVFR possible. Chance SHRA,
Slight chance TSRA.
Saturday Night: VFR. Chance SHRA.
Sunday: VFR. NO SIG WX.
Sunday Night: VFR. Slight chance SHRA.
Columbus Day: VFR. Chance SHRA.
Monday Night: Mainly VFR, with local MVFR possible. Chance SHRA.
Tuesday: Mainly MVFR, with local VFR possible. Chance SHRA.
