AREA FORECAST DISCUSSION
National Weather Service Burlington VT
1207 PM EDT Thu Jun 20 2019

.SYNOPSIS...
The threat for moderate to heavy rainfall will exist this
afternoon and tonight over a good part of the North Country.
Localized flooding is possible. Cooler and drier weather is
expected for Friday and Saturday. A warming trend begins on
Sunday and continues into early next week. Dry weather will
continue on Sunday...then the chances for showers and some
thunderstorms will increase early next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 1156 AM EDT Thursday...Based on latest hires guidance and
heavy rain already falling upstream decided to issue a Flash
Flood Watch for the North Country for this afternoon and
evening. The combination of 0.5-1" of rainfall that has already
fallen along with the potential for another 1-3" in widespread
shower will embedded thunderstorms could cause localized flash
flooding. One hour FFG is on the order of 1-1.5 inches and 3
hour flash flood guidance is between 1.8 to 2 inches. So we
could depending on where the heaviest rainfall occurs we could
see rainfall totals exceed what the ground is capable of
absorbing.

Guidance is continuing to strong the strong band of showers
currently over southern Vermont will eventually start to pivot
and track northeast across the rest of the North County. Current
precip totals are between 0.25 to 1 inch already in the North
Country and upstream rainfall totals have exceeded 1.5 to 2
inches under the strongest convection. This should lead to
sharp rises on small streams and areas of poor drainage while
main stem rivers will rise but should stay just below flood
stage.

Previous Discussion... Potential for moderate to heavy rainfall
exists this afternoon and tonight across much of the North
Country...generally from the northern Adirondacks eastward
across the Champlain Valley and remainder of Vermont.
However...overall impacts may be limited to minor flooding of
smaller rivers and streams, ponding of water on roadways, and
minor field flooding. The bottom line is most of the area should
receive one to two inches of rain with amounts closer to three
quarters of an inch out across the Saint Lawrence Valley. This
covers the today through Friday morning period with the best
potential for the heavier rain coming this afternoon and
tonight. There has been a bit of a northward shift of where
heavy rainfall might occur. Main upper trough will remain west
of the area today but a lead shortwave trough coming out of the
Ohio Valley will work its way up across our area today. This
will help to generate a low pressure system over the southern
Adirondacks with a frontal boundary extending northeast across
Essex County New York...Addison County Vermont...and up into
Essex County Vermont. This boundary will become the focus for
more concentrated precipitation this afternoon and evening...
especially as higher precipitable water values spread northward
today. We should see values around 1.75 inches which will help
enhance the potential for heavier precipitation. Composite
analysis also suggests that if any instability were to develop
it will be down across portions of Rutland and Windsor
counties... and especially points south. Have thus included the
mention of thunder in these areas for this afternoon and
evening. With all the cloud cover and deeper moisture moving
into the region high temperatures today will generally be in the
upper 60s to lower 70s.

Lead shortwave moves out of the area tonight and with upper
trough axis progressing across the region later tonight...we
should begin to see a well defined back edge to the
precipitation develop later tonight across the Saint Lawrence
Valley. This back edge will progress quickly eastward Friday
morning and most of the precipitation will be east of the area
by midday on Friday as north to northwest flow aloft becomes
established. There could be some lingering showers in the
mountains Friday afternoon with highs generally in the upper 60s
to mid 70s.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...
As of 445 AM EDT Thursday...We are in the deep cyclonic N to NW
flow behind the upper low in the Canadian maritimes Friday
night with cold air advection through the column. It appears
there may be a weak short wave in the flow as well. This
combined with a little low level moisture and upslope flow is
enough to keep a slight chance of a mainly mountain shower or
sprinkle going into the overnight hours. Expect low temps to be
in the mid 40s to mid 50s under partly cloud skies.

Saturday looks to be a partly sunny day across the North Country
with some isolated showers possible mainly across northeast VT. One
last short wave with a cold pocket moves through the region and when
combine with daytime heating will generate some weak instability and
resulting chance of showers. 850 temps get up to about 9-10C so high
temps will range through the 70s.  Expecting a bit of a NW breeze of
15 to 25 mph as well.

Saturday night should be quite similar to Friday night with clear
skies and light northwest flow and low temps in the mid 40s to
mid 50s.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 445 AM EDT Thursday...The NW flow aloft continues on
Sunday with the upper level ridge still to the west but with
rising heights and dry column it should be a nice day across the
North Country. Temps should warm into the upper 70s to low 80s
as 850 temps rise to 11-12C and push temps to around 80. It
looks like the ridge aloft will move remain off to our west for
much of Monday into Monday night. The ridge finally breaks down
with an approaching trof on Tuesday. This is a bit slower than
previous forecasts so it may be warmer and drier for Monday. If
we stay sunny current forecast of lower 80s could turn into mid
80s but we'll see. Models start diverging on the solutions for
Tue-Thu with the approach of another upper trof with the EC/CMC
more or less on the same page with a deeper slower closed system
and the GFS less amplified and a bit faster. For now keeping
chances of showers and slight chance of thunder through the
period until we get closer. It appears that we'll continue to
see seasonal temperatures with highs in the mid 70s to mid 80s
and lows in the mid 50s to mid 60s.

&&

.AVIATION /16Z THURSDAY THROUGH MONDAY/...
Through 12Z Friday...Ceilings and visibilities will be lowering
as the morning wears on. Conditions begin as VFR or MVFR with
respect to ceilings...but lower into the 500-1500 foot range
through 06z before slowly improving. Visibilities will be
VFR...then lower into the 3 to 5 mile range after 16z as rain
becomes widespread over the area. Visibilities will improve
after 06z and eventually return to VFR. Winds will generally be
under 10 knots through the period...with a noticeable wind shift
to the northwest after 06z.

Outlook...

Friday: Mainly VFR, with local MVFR possible. Slight chance SHRA.
Friday Night: VFR. Slight chance SHRA.
Saturday: VFR. Slight chance SHRA.
Saturday Night: VFR. NO SIG WX.
Sunday: VFR. NO SIG WX.
Sunday Night: VFR. NO SIG WX.
Monday: VFR. Chance SHRA.

&&

.HYDROLOGY...
As of 1206 PM EDT Thursday...A Flash Flood Watch is in Effect
through 11 PM this evening. Still looking at a general
widespread one to three inch rain event. Axis of highest amounts
was initially over southern Vermont...but as low pressure and
surface boundary set up across portions of the northern
Adirondacks in New York and extended into Vermont from Addison
County northeast up into Essex County Vermont. Heavier rain may
be concentrated across this area this afternoon and evening
before boundary shifts east. Southern areas will have the best
potential to see some thunderstorms and this could enhance
rainfall totals across this area as well. Overall mainstem
rivers are not expected to reach flood stage...but the East
Branch of the Ausable and Otter Creek might be two to watch.
Otherwise impacts related to the one to two inch rainfall
include sharp rises on smaller rivers and streams which could
lead to localized flash flooding...minor field flooding...and
ponding of water on roadways.
