Area Forecast Discussion
National Weather Service Burlington VT
155 PM EDT Mon Aug 3 2020

.SYNOPSIS...
A brief break in active weather will occur today in the wake of
exiting low pressure to the northeast and Tropical Storm Isaias
approaching from the south. Widespread rain associated with the
tropical cyclone will develop across the region early Tuesday and
become moderate to locally heavy Tuesday evening into Wednesday
morning. High pressure and dry conditions return for the end of the
work week and into the weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 1027 AM EDT Monday...Forecast remains on track this
morning with clouds beginning to break across the Champlain
Valley. A cold front has worked into northern New York and will
continue spreading eastward throughout the day. Continued
clearing is expected but temperatures will remain steady through
much of the day before gradual warming this afternoon.

Previous Discussion...Looking at a fairly quiet day to start
the work week before active weather returns late tonight into
mid- week. Low pressure responsible for yesterdays severe storms
continues to pull northeast through east-central Quebec, but a
trailing frontal boundary is still poised to our northwest
across the Ottawa and St. Lawrence River valleys. A few showers
are streaming out ahead of this boundary and will try to work
into portions of northwest New York early this morning but not
expecting much more than an increase in cloud cover and a few
isolated showers or sprinkles through mid- morning. Thereafter,
as the boundary moves through drier mid-level air working into
the region will scatter out clouds for a partly sunny afternoon
with temps rising to near normal values in the mid 70s to low
80s. Dewpoints should drop pleasantly into the upper 50s to low
60s as well, so a it should be a nice afternoon and evening.

Tranquil conditions will continue into the early overnight before
clouds increase towards the midnight hour and onward as moisture
associated with tropical cyclone Isaias will begin to advance into
the mid-Atlantic and Northeast. Showers will begin to work into
southern portions of the CWA toward daybreak, with lows mild in the
60s for most areas except mid/upper 50s in the NEK.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
As of 427 AM EDT Monday...A flash flood watch has been issued for
Essex County, NY and all of VT, except Grand Isle county from 18z
Tues until 15z Weds for 1 to 3 inches of rainfall and the potential
for localized flash flooding due to very high rainfall rates.

Latest 00z models and guidance from our national centers WPC/NHC has
a slight shift westward in the track of tropical system Isaias,
resulting in slightly more precipitation across the Champlain Valley
and parts of VT and the eastern Dacks.

Large scale pattern shows deep southerly flow with significant
moisture transport along the eastern seaboard on Tues into Weds,
while mid/upper lvl digs acrs the central Great Lakes. This feature
will help capture tropical system Isaias on Tues night into Weds and
quickly track the system from eastern MD at 18z Tues to near
Lebanon, NH by 06z Weds. This track has shifted slightly further
west, resulting in more qpf into the CPV/eastern Dacks of our cwa.

Guidance is indicating a few ingredients coming together for a
predecessor rain event ahead of tropical system Isaias on Tuesday.
The synoptic scale features include rrq of 250mb jet of 100 to 115
knots lifting acrs our cwa, helping to promote deep ascent, ahead of
mid/upper lvl trof. In addition, 5h vorticity is streaming acrs our
cwa in the fast confluence flow aloft, along with the nose of 850mb
jet of 45 to 55 knots. These factors, combined with pws climbing
btwn 1.50 and 2.0 supports the development of widespread light rain
acrs our cwa on Tuesday, with areas of moderate rain possible where
llvl forcing is better. Rainfall generally 0.25 to 0.75 on Tues acrs
our cwa.

By 00z Weds an area of moderate to heavy rainfall from Isaias will
overspread our central/eastern cwa. The exact axis of heaviest
rainfall will be determined by the eventual track of the system, but
crnt fcst has shifted the heavier qpf axis western into parts of the
CPV. Very strong llvl moisture advection is present on Tues evening,
associated with nose of a 850mb jet of 55 to 65 knots, along with
good ulvl divergence signature and deep available moisture with pws
near 1.75". These factors combined with strong lift, will produce
localized very heavy rainfall rates of 0.50 to 1.50 inches per hour
acrs our fa for a period of time on Tues evening. The heaviest
rainfall rates should shift east of our fa by 06z Weds, as well
defined mid/upper lvl dry slot develops by early Weds morning. Total
qpf will range from near 1.0 SLV to localized 3 inches acrs portions
of VT by 12z Weds.

Given the slightly westward shift in the track, the threat for
stronger winds have developed across portions of eastern and
southern VT. Have noted bottom of the mixed layer at VSF shows winds
of 30 to 35 knots around 06z Weds, so thinking some localized gusts
up to 40 mph will be possible in the heavier convective downpours.
The core of strongest 925mb to 850mb winds impacts our
eastern/southern cwa btwn 00z and 09z Weds. Some localized gusts up
to 40 mph also possible acrs the favorable downslope regions of the
southern Greens from Mendon Gap to Danby.

Temps generally on the cooler side for Tues with highs in the 70s,
with lows in the 60s overnight and back into the mid 70s to lower
80s on Weds.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 427 AM EDT Monday...A generally quiet period of wx anticipated
for mid week into next weekend with building sfc high pres. Still
have to watch weak embedded short waves in the flow aloft and if
they can advect moisture northward into our cwa, for potential
showers over the weekend. Temps start near normal with values in the
mid 70s to lower 80s, but warm well into the 80s by Saturday as
progged 925mb temps climb btwn 20-22c. Lows mainly in the upper 40s
to lower 60s depending upon location. Given the anticipated
rainfall, some patchy fog is possible in the deeper valleys for late
week, especially with light winds associated with sfc high pres
overhead.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Through 18Z Tuesday...Currently VFR conditions across the
forecast area as clouds lift and push eastward ahead of a
frontal boundary. Brief clearing is expected behind this front
and will persist through the afternoon and evening with FEW-
SCT at 060-080 kft. Late tonight and through the overnight
hours, high clouds will begin to increase as low pressure
approaches from the west, and tropical moisture associated with
TS Isaias is advected northward. This will lead to a trend
toward MVFR to IFR cigs by 10-12z for all TAF sites expect RUT
where easterly downslope flow will preclude low cloud
development until early afternoon. In addition, showers are
expected to begin Tuesday morning between 09-12z and spread
northeastward bringing a reduction to MVFR vis through the
remainder of the TAF period. The heaviest rainfall and greatest
reduction in cigs/vis is expected to arrive after 18z as Isaias
tracks through eastern Vermont.

Outlook...

Tuesday Night: Mainly VFR, with areas MVFR possible. Windy with
gusts to 35 kt. Definite RA.
Wednesday: VFR. Chance SHRA.
Wednesday Night: VFR. NO SIG WX.
Thursday: VFR. NO SIG WX.
Thursday Night: VFR. NO SIG WX.
Friday: VFR. NO SIG WX.
Friday Night: VFR. NO SIG WX.
Saturday: VFR. NO SIG WX.

.HYDROLOGY...
As of 427 AM EDT Monday...A flash flood watch has been issued
for Essex County, NY and all of VT, except Grand Isle County
from 18z Tues until 15z Weds. Rainfall of 1 to 3 inches is
expected, which given the potential for very high rainfall
rates, could produce localized flash flooding across complex
terrain and poor drainage in urban areas. 1 hour flash flood
guidance across our HSA is between 1.5 and 2.0", while 3 hour
guidance is in the 2 to 3 inch range. The heaviest period of
rainfall will occur between 21z Tues and 06z Weds acrs the watch
area. Sharp rises on streams and rivers are anticipated, but
the threat for widespread river flooding is low at this time,
due to the quick movement of precipitation across our region.
