Area Forecast Discussion
National Weather Service Burlington VT
132 PM EDT Sun Jun 27 2021

.SYNOPSIS...
Warm and humid conditions will continue across the North Country
through Monday, before a weak front produces slightly cooler air
with increasing chances for showers and thunderstorms. Highs
today will be in the upper 80s to mid 90s with similar heat
index values. Expect another very warm and muggy night with lows
generally in the mid 60s to mid 70s tonight and again on Monday
night.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 1043 AM EDT Sunday...Forecast for today remains in good
shape with just a few tweaks made to sky cover and temps. Seems
cloud cover is impacting temps across the region this morning,
keeping values just a couple of degrees cooler than forecast and
with the likelihood of cloud cover persisting into the afternoon
did lower max temps a degree or two. Will probably see heat
advisory criteria met for an hour or two in the Champlain Valley
with highs in the lower 90s and dewpoints in the mid 60s, but
it's borderline so will continue with no headlines. Either way
you slice it, it's going to be hot today so please take the
necessary precautions.

Previous Discussion from 648 AM...The near term focus wl be
heat today and Monday, followed by convective chances on Monday
aftn. Water vapor shows building mid/upper lvl ridge acrs the
Mid Atlantic states while mid lvl moisture associated with warm
frnt continues to lift into southern Canada. Still expecting
some mid/upper lvl clouds to linger near International Border
this morning, but by this aftn, soundings indicating deep dry
layer from 925mb thru 400mb. This drying/subsidence aloft should
result in plenty of sunshine and very limited chcs for
showers/storms. Soundings support super- adiabatic lapse rates
of >10 C/km from sfc thru 800mb this aftn, resulting in slightly
drier dwpts mixing down to the sfc, and lowering heat index
values slightly. However, this drying trend should allow temps
to reach full potential with highs in the upper 80s to mid 90s,
I have placed 95F at PBG/BTV and 90-92F at RUT/MPV/VSF/MSS with
upper 80s NEK/SLK. Similar type heat index values are
anticipated. In addition, soundings support localized gusty
winds as mixing improves this aftn, with gusts 25 to 35 mph
likely in the SLV and CPV from 15z thru 22z today, some gusts
near 40 mph would not be surprising the SLV associated with
aligned sw flow and on the northwest facing downslope areas of
the northern Dacks from Malone to Ellenburg Depot.

Tonight another very warm and muggy night is anticipated with
dwpts rising toward 70F as sunset occurs. In addition, expect
gradient to continue with south/southwest winds of 10 to 20 mph.
These conditions wl hold temps in the mid 60s NEK/SLK to mid 70s
CPV/SLV and Lower CT River Valley.

For Monday...mid/upper lvl ridge continues with just a weak sfc
boundary dropping southward acrs the fa. This results in
slightly cooler 925mb temps in the 21-24C range, with warmest
values near VSF. Expecting highs to range from mid 80s Dacks to
mid 90s VSF, based on thermal profiles, with heat index values
in the 88F to 94F range. Next question wl be convective
potential. Have cut back on pops, because of limited upper lvl
forcing, still anti-cyclonic flow aloft with no height falls and
very weak sfc convergence. However, still think some
disorganized/pulse type activity is possible along instability
gradient from northern Dacks into central/southern Vt on Monday
aftn. High res data continues to show an axis of sfc based CAPE
of 1000 to 1600 J/kg, with some better 0 to 6 km shear values of
25 to 30 knots approaching the International Border by 21z.
Expect scattered aftn/evening showers/storms to develop aft 16z,
with some localized heavy down pours possible, but with limited
upper lvl support, coverage should be widely scattered. Have
mention 15 to 30% pops most locations.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/...
As of 433 AM EDT Sunday...Little change expected with the upper
pattern for Monday night into Tuesday. If anything, the Mid-Atlantic
ridge will begin to pivot as it continues to build westward
into the Ohio River Valley, allowing flow across the Northeast
to become more westerly. Embedded vorticity maxima aloft will
once again stretch across the area, resulting in increasing
clouds across the North Country overnight into Tuesday. Still,
temperatures overnight should be a little cooler than the night
prior as winds decrease and become westerly, with lows in the
upper 60s. Likewise, highs on Tuesday should be a little lower
than Monday's topping off in the mid to upper 80s. During the
afternoon, there exists a chance of showers with thunderstorms
possible across portions of the Adirondacks and south-central
Vermont. However, as has been the pattern the past several days,
the absence of a forcing mechanism will cause the showers to be
isolated to scattered in nature.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
As of 433 AM EDT Sunday...Wednesday still looks to be the better day
for rain potential as a more potent shortwave passes within the flow
aloft. We could see a weak surface boundary accompany this feature
which would further aid in the development of showers and possible
thunderstorms. At this time, instability looks meager, but a lot can
change between now and then. With any showers/thunderstorms that do
develop, there exists the potential for locally heavy rain with
PWATs in the 1.5-2 inch range. Temperatures will continue with
their cooling trend with highs on Wednesday being near normal in
the upper 70s to mid 80s.

Beyond Wednesday, the evolution of the upstream upper low becomes
uncertain with global guidance offering a variety of solutions. For
now, have stuck close to the GFS/ECMWF with the CMC being more of an
outlier. In any case, we will see ongoing chances for precipitation
through the end of the week as the upper low draws near.
Temperatures will remain near normal with highs in the mid 70s to
low 80s and overnight lows in the upper 50s to low 60s.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
Through 18Z Monday...Gusty SSW winds continue to be the main
aviation impact this afternoon with local gusts in the 20-30kt
range at KMSS/KBTV/KSLK and up to 20kts elsewhere. Otherwise,
VFR conditions prevail under SCT/BKN mid clouds. Overnight a
boundary north of the border will sag southward providing a
chance of showers and perhaps some embedded rumbles of thunder,
but conditions remain largely VFR except at KMSS/KSLK where
ceilings will lower to MVFR from around 10-17Z. Winds abate
overnight as well, lowering to 8-12kts through sunrise, but
become slightly gusty again up to 16-20kts from mid-morning
Monday onward.

Outlook...

Monday Night: VFR. Slight chance SHRA.
Tuesday: VFR. Chance SHRA, Slight chance TSRA.
Tuesday Night: Mainly VFR, with local MVFR possible. Chance SHRA.
Wednesday: Mainly VFR, with local MVFR possible. Chance SHRA,
Slight chance TSRA.
Wednesday Night: Mainly VFR, with local IFR possible. Chance
SHRA, Slight chance TSRA.
Thursday: Mainly MVFR, with local IFR possible. Chance SHRA.
Thursday Night: MVFR/IFR conditions possible. Chance SHRA.
Friday: Mainly MVFR, with local IFR possible. Chance SHRA.
