Area Forecast Discussion
National Weather Service Burlington VT
625 PM EDT Sat Aug 13 2016
.SYNOPSIS...
A stationary front across southern Vermont and central New York
will begin to lift northward as a warm front this evening and
overnight. This will result in increasing coverage of showers,
with a few embedded thunderstorms through the first half of
tonight. With the very humid air mass along the front, some
locally heavy rainfall remains possible. A low pressure center
along the frontal zone will shift to the east early Sunday. A
trailing cold front will bring scattered showers and thunderstorms
on Sunday, but with partly sunny conditions otherwise and highs in
the low to mid 80s. Surface high pressure returns with mostly
sunny and drier conditions for Monday, with valley highs generally
reaching the lower 80s.
&&
.NEAR TERM /THROUGH SUNDAY/...
As of 622 PM EDT Saturday...Narrow corridor of severe thunderstorm
potential across s-central VT next several hours with upstream
squall line across e-central NY. Quick update to account for
Severe Thunderstorm Watch #444 through 05Z. Main threat remains
heavy rainfall, but a few stronger cores could produce strong
winds and hail.
Previous discussion...North Country remains in frontal zone, with
quasi-stationary sfc front extending E-W across far srn VT and
south of the Adirondacks at 19Z. Thru early this evening, main
focus for shower and thunderstorm activity will be just north of
the front, affecting Essex NY county, and s-central VT. Could see
some locally heavy downpours, with up to 1" rainfall possible with
heavier/slower moving cores. Further north, air mass is quite
stable with low- level frontal inversion and associated stratus
deck holding firm in most sections. Expectation is that weak
surface low across sern Ontario will lift newd overnight, and
begin to move the bndry nwd as a warm front later this evening and
overnight. As that occurs, significant sloped ascent occurs across
nrn NY into central/n-central VT, enhanced by SW winds 35-45kt in
the 850mb to 700mb layer. The 12km NAM and RAP indicate elevated
instability up to 500 J/kg, along with PW values of 2 to 2.25".
Thus, looking at redevelopment of numerous showers/embedded
thunderstorms after 22Z across nrn NY, and after 00Z across
central/nrn VT. Given PW values 2-3SD above climo, will maintain
flash flood watch overnight...and will especially need to monitor
portions of St. Lawrence Co. NY and Washington/Orange in VT where
antecedent rainfall of 1-3" occurred yesterday. Overnight lows
will not drop much from current readings as winds turn light
south/southeast. Generally upr 60s to lower 70s.
As wave low tracks to our north and east between 12-15Z Sunday,
will see trailing cold front associated with this system move
across the region and in its wake, drying NW flow as PWATs fall
below 1.5 inches by Sunday evening. With daytime heating, will
anticipate the redevelopment of isold/sct showers and a few
thunderstorms, especially across central and s-central VT during
peak heating hrs. On the whole though, better day than Saturday,
with skies partly sunny and slow lower of dewpoints from NW-SE
during the afternoon hours. High temps mainly low-mid 80s.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY/...
As of 1201 PM EDT Saturday...Expect the showers and thunderstorms to
exit the region Sunday evening as the front moves south and out of
the North Country. A warm and muggy airmass will still be in place
overnight so I've only got lows in the mid to low 60s. With all of
the residual moisture in place, fog is a good bet on Sunday night so
I have patchy fog mentioned in the favoured locations including the
protected river valleys.
By Monday weak ridging at the surface will lead to partly cloudy
skies with quiet weather expected. Expect light to moderate winds
and a nice reprieve from the wet weekend. Max temps during the day
should warm into the upper 70s to low 80s across the North Country.
&&
.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
As of 1201 PM EDT Saturday...High pressure crests overnight on
Monday as the medium ranged guidance points to a pleasant start to
the week through Tuesday. Expect a repeat of Monday on Tuesday with
quiet and dry weather and max temps a few degrees warmer in the low
to mid 80s. Then the synoptic pattern turns more active by mid week
as the medium range deterministic guidance show two systems moving
through the area. The first, on Wednesday, is expected to be a
robust shortwave ahead of the parent upper level trough however
there is a fair bit of inconsistency with regards to specific timing
and intensity. After the shortwave clears north, a frontal system
will slide across the North Country and bring additional rainfall to
the region sometime on Thursday. Good news is expected though as
behind the front Thursday, fair and dry weather is expected to begin
the weekend.
&&
.AVIATION /00Z Sunday THROUGH Thursday/...
Through 18Z Sunday...Areas of MVFR-IFR conditions through tonight
within warm frontal zone. Coverage of showers and thunderstorms
increase after 22Z across nrn NY, and after 00Z across VT, with
locally heavy downpours possible. Winds shift light N-NE to light
SE-S overnight. Generally returning to VFR after 12Z Sunday, with
ISOLD/SCT showers and a few thunderstorms toward early afternoon.
NW wind shift with cold frontal passage 14-17Z.
Outlook 18Z Sunday through Wednesday...
18z Sunday through 12z Monday...ISOLD/SCT tstms through late
afternoon, then mainly clear Sunday night as cold front sweeps
through the region. Patchy fog SLK/MPV 06-12Z Monday.
12z Monday through 12z Wednesday...expect primarily VFR with
overnight patchy fog and IFR.
12z Wednesday onward...MVFR conditions possible with additional
chances for showers and t-storms.
&&
.HYDROLOGY...
As of 350 PM EDT Saturday...Very moist airmass will persist in
warm frontal zone with PW values into Sunday morning of 2-2.25
inches. Increasing coverage of showers and embedded thunderstorms
overnight as S-SW winds increase over bndry...as it retreats nwd
as a warm front. Additional rainfall amts of 1-2" expected, and
any locally higher amts with embedded thunderstorms could yield a
flash flood threat...this evening and overnight.
River levels are low, so we don't anticipate the larger rivers to
become overwhelmed, especially since heavy rain footprints will be
sub-basin in size.
