Area Forecast Discussion
National Weather Service Burlington VT
208 PM EDT Sat Jul 9 2016

.SYNOPSIS...
An upper level low will continue to affect the North Country
through the weekend with periods of rain and scattered
thunderstorms. Cooler and drier conditions are expected in the
wake of this upper low to start the work week, followed by
increasingly hot and humid conditions mid to late next week. The
chance for showers and thunderstorms return for the latter half of
the week.

&&

.NEAR TERM /THROUGH SUNDAY/...
As of 208 PM EDT Saturday...Little change with this update.
Continue to see widespread showers and thunderstorms early this
afternoon with locally heavy rains. Additional small footprints
of 2" of rain in the on the edge northern St. Lawrence Valley.
Continue to monitor the threat of flash flooding if it gets into
more mountainous terrain. Flash flood guidance in the 2-3 inch
range over 1 to 3 hours.

Watching St. Lawrence/western Adirondacks closely for severe
threat as it has warmed to near 80 but cloud cover will limit
threat otherwise. Hi res models suggest the surface low and low
level convergence will be vcty KMSS though the pm. Looking at
CAPE over 1000 J/kg per RAP/HRRR but the deep layer shear should
be diminishing from 35 kt to below 25 kt later this afternoon.

Back door front will remain nearly stationary today in the vcty
adirondack with cooler SE flow to the east over the Champlain and
the rest of VT. This front will continue to provide the focus for
our weather through tonight.

Closing off upper trough progress eastward today providing upper
level divergence and lift along with some cooling aloft.

Abundant clouds will keep temperatures generally in the mid 60s
to mid 70s with warmest temperatures in the Saint Lawrence Valley.
Coolest temperatures today will east the Greens as low level
marine layer filters in from the east.

Heading into this evening, area of low level deformation will
continue the chance of showers into the overnight as it moves
across the region. But as we head towards early Sunday morning,
the mid-level trough moves into the closing off near MSS. Areas
of vorticity rotating about the trough will keep clouds across the
region with continuing chance of showers. Temperatures tonight and
Sunday will continue to be mild.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY/...
As of 424 AM EDT Saturday...Other than some lingering showers
Sunday evening...drier northwest flow aloft develops through
Monday. Clearing skies late Sunday night into Monday will allow
for temperatures to recover from the below normal readings over
the weekend, but highs on Monday should still be a few degrees
below normal.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 424 AM EDT Saturday...Upper ridge builds into the region
Tuesday and Wednesday with low level warm air advection beginning
in earnest. Dry weather continues for most of this time period
with the exception for a few late day showers or storms on
Wednesday. Based on the 925 millibar temperatures highs on Tuesday
and Wednesday will be well above normal with highs in the 80s to
around 90 on Tuesday and mid 80s to lower 90s on Wednesday. Upper
ridge moves east late Wednesday and southwest flow aloft becomes
established over the region Wednesday night through Friday.
Moisture will begin to increase during this time period and with
high temperatures Thursday and Friday remaining in the
80s...tempered back as a result of increased clouds...there should
be sufficient instability developing for convection. Flow aloft on
Thursday remains relatively weak thus storms should be more pulse
in nature. Perhaps on Friday storms could get more organized as
deep layer shear increases over the area along with increasing
dynamic support and a cold front approaching from the west.
Something to keep an eye on over time.

&&

.AVIATION /18Z Saturday THROUGH Thursday/...
Through 12Z Sunday...Prevailing MVFR cigs but locally IFR vsby
in showers and scattered thunderstorms through the early evening.
All a result of a backdoor front in the Adirondacks and low
pressure south of KMSS.

With all the precip already experienced and more expected, local
LIFR in fog down to 1SM or lower and cigs below 1000 ft possible
tonight.

Flow turns around to more northerly on Sunday looking at IFR cigs
early improving to MVFR during the morning but still looking a
good chance of showers especially over VT.

Outlook 18z Sunday through Thursday...
Sun night: Periods of MVFR/IFR in showers ending.
Mon-Wed: VFR under high pressure.
Thu-Fri: VFR with isolated/scattered SHRA/TSRA, briefly MVFR/IFR
with a cold front.

&&

.MARINE...
A lake wind advisory and lake thunderstorm advisory are in effect.
Upper low over the region is producing multiple showers and
thunderstorms across the area and will continue to do so through
the early evening. Southerly winds are increasing to 15-25 knots
across the lake and should remain there until the overnight hours
until the low begins to pass and the gradient loosens slightly but
winds should still be in the 10-20 knot range tomorrow.

&&

.BTV WATCHES/WARNINGS/ADVISORIES...
VT...None.
NY...None.
