Area Forecast Discussion
National Weather Service Buffalo NY
1108 PM EDT Fri Nov 1 2019

.SYNOPSIS...
Scattered lake effect rain and some wet snow showers will continue
east of the lakes tonight before high pressure builds in briefly
Saturday. Another surge of colder air will bring lake effect snow
across the higher terrain east of the lakes later Saturday night and
Sunday morning, with moderate accumulations possible in some areas.

&&

.NEAR TERM /THROUGH SATURDAY/...
The powerful storm which produced the significant wind event across
western and north central New York is over eastern Quebec heading to
Atlantic Canada. Winds have quickly come down across the region.
What a difference compared to 24 hours ago!

The airmass is just cold enough (-4c at 3-5kft) for a marginal lake
response. A few light rain and snow showers are drifting in off of
Lake Erie toward Buffalo, but by far, the better band of lake effect
rain and snow showers is streaming in across the Tug Hill with web
cam at Redfield showing snow in the air. This band may produce
additional very minor snow accumulations across higher terrain into
the overnight hours. Boundary layer flow will eventually back more
southerly overnight carrying any lake induced precipitation
northward, with the precipitation eventually dissipated Saturday
morning. Lows tonight will be in the mid 30s on the lake plains,
with mid to upper 20s in the colder interior locations.

Quieter conditions will start Saturday once any lingering lake
effect precipitation fades away, as high pressure briefly
builds in. This should allow for a mostly dry day.

A clipper system will travel across the southern Canadian provinces,
centering over Ontario just north of Lake Superior by 18Z Saturday.
This advancing clipper system will allow a weak cold frontal
boundary to approach western New York by the end of the day.
Marginally cold air within the southwest flow ahead of the
front is expected to generate a band of lake effect
precipitation into the region off Lake Erie toward Saturday
evening. Thermal profiles suggesting the bulk of this will be
rain, although some mix with wet snow is possible over the
highest terrain south and east of Buffalo.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
Saturday night low pressure near James Bay will sweep a cold front
across our area from west to east...with cold advection in its wake
driving initial 850 mb temps of -3C/-4C downward to the -5C to -8C
range. With the low level flow also veering from southwesterly to
westerly...all of this should result in initial lake-enhanced rain
showers to the northeast of both lakes shifting southward to areas
east of both lakes while also mainly transitioning over to lake and
orographically-enhanced snow showers. As is typically the case...
this process will take place first off Lake Erie (during the
evening)...and later on off Lake Ontario (during the later evening
and early overnight hours). With the low level flow trending to
almost due westerly across both lakes...the Lake Erie lake effect
activity will steadily push southward and (eventually) settle mainly
across Chautauqua and Cattaraugus counties during the course of Saturday
night...while the Lake Ontario activity will largely settle across
the Tug Hill Plateau. Once in these areas...a general steady-state
westerly flow will keep the activity largely in place through Sunday
morning.

Off both lakes...lake parameters will generally be most favorable
from the second half of Saturday night into Sunday morning...when
favorably deep moisture will be in place beneath inversion heights
of 10-11 kft...and when the steering winds will be most aligned.
This should result in the most organized activity occurring over
the traditional lake effect areas east of both lakes during the above
time frame...with the activity then notably weakening through the
course of Sunday and eventually lifting back northward as diurnal
effects increase...and as high pressure builds into the region from
the Ohio Valley and brings a falling cap...low level drying...and
a slowly backing/increasingly sheared low level flow.

Given expected thermal profiles through the lake effect event...the
bulk of any accumulating snowfall should tend to be mostly confined
to the higher terrain of the aforementioned areas from later Saturday
evening through the first part of Sunday...with little to negligible
accumulations expected across the lower elevations. The above said...
the overall setup continues to lend increasing confidence to some
lower-end advisory-type snowfall amounts (3-6") across the Tug Hill
and the higher terrain of Chautauqua and Cattaraugus counties...and
with both this and the fact that this will be the first accumulating
snowfall of the season in mind...we have elected to hoist winter weather
advisories for the above areas for Saturday night and Sunday. Again...
the bulk of the accumulating snowfall in these areas is expected to
come between Saturday night and the first part of Sunday...with
increasing diurnal influences and the weakening nature of the activity
then resulting in steadily lowering accumulations through the remainder
of Sunday.

Outside of the precipitation associated with the cold frontal passage
and the main areas of lake effect/lake enhancement...this period will
feature mainly dry conditions and a trend to well below average
temperatures...with highs on Sunday only expected to be in the upper
30s to lower 40s for the most part.

By Sunday evening the last vestiges of the lake effect activity will
be in the form of some dying rain and snow showers that will lift
northward across the Niagara Frontier/Jefferson County and dissipate
through the course of the evening...with mainly dry weather then
anticipated through the remainder of the night and Monday as the
surface high slowly exits eastward across New England...and as the
next wave of low pressure approaches from the Upper Great Lakes.
With the developing warm advection regime in between these two
systems...Monday should also feature a return to milder conditions...
with highs rebounding into the upper 40s and lower 50s in most areas.

Monday night and Tuesday the aforementioned broad low will gradually
make its way northeastward across Quebec Province...while slowly
pivoting its trailing cold front across our region. This will result
in an increasing potential for at least some scattered showers through
the last 24 hours of this period...with some lake enhancement also
becoming possible east of both lakes during Tuesday as temperatures
aloft begin to cool.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
Behind Tuesday's cold front...somewhat colder air will again build
across the area Tuesday night...with a short-lived lake response east
of both lakes likely to die out on Wednesday with increasing diurnal
influences and as surface-based ridging and much drier air builds back
across our region. Meanwhile...the colder airmass will drive temps
back to below normal levels...with highs on Wednesday mainly ranging
in the lower to mid 40s.

After that...the GFS/ECMWF are coming into significantly better
agreement on the passage of yet another fast-moving surface wave/
cold front between Wednesday night and Thursday...with a northwesterly
flow of much colder air then following for Thursday and Friday with
consensus 850 mb temperatures falling to between -12C and -14C. Should
this come to fruition...this would result in temps falling to WELL
below average for the end of next week...with another mixed bag of
rain and snow showers Wednesday night/Thursday transitioning into
some northwest-flow lake effect snow showers for Thursday night
and Friday.

&&

.AVIATION /03Z SATURDAY THROUGH WEDNESDAY/...
Scattered lake effect showers will continue tonight east of the
lakes, especially Lake Ontario. MVFR cigs with spotty MVFR vsby
possible in these showers. What remains of these showers will move
north late tonight as boundary layer flow veers to the southwest.
The lake effect clouds and scattered showers will dissipate by
daybreak Saturday. Otherwise, expect a broken to overcast deck of
lower VFR cigs to gradually fade away through the night away from
the lakes.

Outlook...
Saturday...Mainly VFR. A Chance of showers.
Saturday night and Sunday...Mainly VFR, except IFR in lake effect
rain and snow showers east of the lakes.
Monday and Tuesday...VFR/MVFR with a chance of showers.

&&

.MARINE...
As deep low pressure heads toward Atlantic Canada, expect winds and
waves to continue to subside across the lakes, though Small Craft
Advisories linger especially on Lake Ontario through later tonight,
mainly due to the residual higher waves. High pressure over the area
later tonight into Saturday will allow for relatively lighter winds
on the lakes.

A clipper low enters the Great Lakes Saturday and will extend a cold
front across the lakes by Saturday night. West winds will increase
behind the front and waves will build again, likely bringing a round
of small craft advisory criteria conditions for Saturday night
into Sunday.
