Area forecast discussion, Nov 15, 6:54 PM EST, 1 minute before
Area Forecast Discussion
National Weather Service Buffalo NY
654 PM EST Sun Nov 15 2020

.SYNOPSIS...
A deep storm system over eastern Canada will generate damaging winds
for parts of the region tonight along with widespread precipitation.
This could include a few inches of wet snow across the higher
elevations of the Southern Tier and also on the Tug Hill. The strong
storm system will slowly exit across Quebec on Monday and this will
allow winds to very gradually subside through Monday night.

&&

.NEAR TERM /THROUGH MONDAY/...
...DAMAGING WINDS EXPECTED TONIGHT...

A very deep yet progressive mid level trough will move across the
Great Lakes this evening, taking on a negative tilt with time. The
associated surface low will pass south of James Bay through tonight
while deepening to around 979MB.

WINDS...

Model guidance continues to support a tropopause fold and
stratospheric PV intrusion as the base of a deep trough crosses the
Lower Great Lakes with the 1.5 PVU surface decending to around 550
MB. This, combined with strong cold advection and post-frontal
pressure rises will support a period of strong subsidence and steep
lapse rates through the low/mid levels. The magnitude of post-
frontal winds aloft suggest gusts of 65 mph northeast of Lake Erie
from Buffalo to Rochester. A few 70 mph gusts are possible close to
Lake Erie. The strongest gusts northeast of Lake Erie will be mid
afternoon through mid evening. Gusts across Jefferson County will
likely be closer to 60 mph. Farther inland, expect gusts of around
50 mph in Finger Lakes region.

PRECIPITATION...

In the wake of the system, lake effect rain will develop northeast
of Lake Erie. This band of rain will initially be over the Buffalo
Northtowns, then drift slowly south to the Southtowns later this
evening before reaching the western Southern Tier late tonight as
boundary layer flow veers more westerly. The rain will mix with snow
overnight across the higher terrain, with very minor accumulations
possible on the hills. Lake effect rain and wet snow showers will
continue Monday across the western Southern Tier and the Boston
Hills and Wyoming County. Spotty 1-3 inch accumulations are expected
late tonight through Monday for the highest terrain, with little or
nothing at lower elevations.

East of Lake Ontario lake effect rain will setup this evening near
Watertown, then drift south to the northern Tug Hill by late
tonight. Lake effect showers of rain and snow will continue across
the Tug Hill region Monday, with snow favored at higher elevations
and rain at lower elevations. Expect several inches of accumulation
across the highest elevations of the Tug Hill, with little or no
accumulation at lower elevations.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
A large scale trough will remain in place over the eastern third of
the U.S. and Canada during most of this period. This will allow for
continued active weather with cooler than normal temperatures.

Monday night, a weak lake response will remain in place through the
early portion of the evening, especially east of Lake Ontario where
temperatures will be a bit cooler. The lake response will strengthen
late Monday evening as a shortwave trough approaches the area from
the Upper Midwest late Monday into Tuesday morning. A cold front
will cross the area, and bring most of the lake bands fully inland
with its passage. Timing on the cold frontal passage looks generally
around daybreak on Tuesday morning, but there is some model
disagreement still with timing of the front. The best chance for
accumulating snow will be across the higher terrain of the North
Country, with some snow also accumulating over the higher terrain of
the Western Southern Tier. Lower elevations can expect mostly a rain
or rain/snow mix through the early morning on Tuesday. Snowfall
amounts over the Tug Hill on Monday night will be around 1 to 3
inches, and in the higher terrain of the Western Southern Tier
around 1 to 2 inches will be possible. Lows on Monday night will be
in the upper 20s to around 30 for the higher terrain, and in the low
to mid 30s for the lower elevations.

Tuesday, behind the passing cold front, winds will begin to shift to
the northwest. As mentioned above, the cold front should briefly
dislodge the lake bands away from the lakes and bring them inland,
bringing rain/snow showers to a more widespread area. Cold air
advection behind the cold front and a passing shortwave trough will
cause lake bands to redevelop southeast of the lakes during the day
on Tuesday. 850H temps of around -7C on Tuesday morning should cool
to around -11C by the late afternoon. Some drier air will be moving
into the region behind the cold front and shortwave trough, so that
will limit some of the lake response. Some guidance is suggesting an
upstream connection with the Georgian Bay and Lake Huron, with a
band over the western end of Lake Ontario and a band over Lake Erie.
Should this become the setup, then where these bands set up, there
will be some locally higher precipitation amounts. If a lake band
sets up from the Georgian Bay and across Lake Ontario, placement of
the band looks best from Niagara County southeast into Genesee
County and into Livingston County during the afternoon on Tuesday,
and slowly shifting eastward later in the afternoon. If a lake band
sets up over Lake Erie with a Lake Huron connection, it looks like
the best chance for precipitation would be Chautauqua County,
especially over the higher terrain of the Chautauqua Ridge.
Precipitation closer to the lakes will be a rain or rain/snow mix,
and change to snow farther inland over the higher terrain. Cold air
advection on Tuesday will also change precip to snow slowly through
the afternoon with lowering elevation. The higher terrain of the Tug
Hill is expected to get a quick half inch or so of snow in the
morning before the band drops south. Otherwise the higher terrain of
the Western Southern Tier should also see around an inch of snow.
Interior areas can expect a coating of snow as temperatures cool
through the afternoon. Guidance is spread on temperatures still for
Tuesday and any fluctuation in what temperatures are on Tuesday can
greatly alter snow potential and amounts. High temperatures on
Tuesday will be in the low to mid 30s for the higher terrain and in
the mid to upper 30s for the lower elevations.

Tuesday night, any remaining lake response will all be in the form
of snow as continued cold air advection brings temps down through
the night. 850H temps cool to around -12C for WNY and around -15C
for the North Country, with some model guidance even cooler than
this. These cooler temperatures with the larger scale trough over
the region still will help continue some of the lake response
Tuesday night. An area of high pressure over the mid-Mississippi
Valley will push east causing increased ridging over the area later
Tuesday night into Wednesday morning. This will start to cut down on
the lake response some over the area. Lows on Tuesday night will be
in the low to mid 20s for areas south of Lake Ontario where lake
clouds are in place, and in the mid teens for the North Country.

Wednesday, a weak lake response will remain in place southeast of
the lakes, tapering off through the morning. This will occur as
ridging continues to increase through the day, and warm air
advection increases 850H temps through the day as well. Temperatures
will be in the low to mid 30s south of Lake Ontario and in the low
20s to low 30s for areas east of Lake Ontario.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
High pressure will be across the eastern Great Lakes Wednesday night
and dry conditions will continue through Thursday. A chilly airmass
will be in place Wednesday night with highs in the upper 20s to mid
30s and lows in the teens to 20s. Cooler conditions possible across
the higher terrain across the western Southern Tier and Tug Hill.

A warm-up is expected Thursday and Friday with high temperatures
reaching the 50s across the region. Forecast consensus has high
pressure moving south and east of the region Friday maintaining dry
conditions into the weekend. A warm front will approach the region
Saturday and Sunday and chances for rain showers increase.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
VFR to MVFR cigs will be found across the region tonight as lake
effect rain/.snow showers will become established northeast of both
lakes. Of greater concern will be the very strong winds throughout
the bulk of the region with wind gusts of 50 to 60 mph through at
least 06z.

On Monday...VFR conditions will be found at most of the TAF sites...
however MVFR cigs will persist in areas of lake effect rain and snow
showers east of both lakes. While sfc winds will lower somewhat...
gusts over 40 kts will still be possible...especially during the
morning.

Outlook...

Tuesday...Lake effect rain and snow southeast of the lakes with
local MVFR/IFR.
Wednesday...Lingering lake effect snow showers to the southeast of
the Lakes with local MVFR/IFR, ending in the afternoon.
Thursday and Friday...VFR.

&&

.MARINE...
Storm warnings in effect for Lake Erie this evening. Gale warnings
are in effect for the remainder of the Lower Great Lakes through
much of tonight. A Gale Warning is also in effect for portions of
the St. Lawrence River.

The strongest winds will develop following the cold front. This
will produce storms to 50 knots behind the front on Lake Erie,
and high end gales to 45 knots this evening on Lake Ontario.
Lower end gales may continue into Monday before winds start to
gradually subside later Monday and Monday night.

&&

.TIDES/COASTAL FLOODING...
A Lakeshore Flood Warning is in effect for the east end of both lakes.
Model guidance has trended stronger with sustained winds to 50 knots
on Lake Erie and to 40 knots on Lake Ontario. Levels on Lake Erie
are expected to reach around 10 feet above low water datum at Buffalo.
This level requires the addition of Niagara County into the warning
for the Upper Niagara River, with flooding possible along the shores
of Grand Island and Cayuga Island.

Wave action will build on Lake Ontario following the passage of this
front, with lakeshore flooding and erosion through Monday afternoon
at the east end of the lake.
