Synopsis
Arctic high pressure will settle across our region today, bringing
record or near record cold along with slowly diminishing snow
showers. The bitter cold will be short lived, as a significant
warm up will begin on Friday and continue through the weekend.

Near term through tonight
Arctic high pressure will continue to build into the region and
bring an unseasonably cold day today. Light intensity lake effect
snow showers south and southeast of the lakes early this morning
will diminish through the morning, before ending entirely by mid day
or early afternoon. Outside of the snow shower activity conditions
will be partly to mostly sunny, but unseasonably cold. High
temperatures will range from the mid teens across interior portions
of the southern tier north country to the lower 20s across the lake
plains. These readings are some 25 degrees below normal, with daily
record low maximums likely to be set.

Very cold temperatures will persist tonight as the high settles over
the area. Widespread low temperatures in the single digits and
teens are expected.

Short term Friday through Sunday
While mid winter temperatures will greet black Friday shoppers
early Friday morning... Fair dry weather can be expected throughout
the day. The large arctic high responsible for the january like
temperatures will push off the coast during the afternoon... And the
clockwise circulation on its backside will allow for more tolerable
temperatures to end the day as the mercury will climb well into the
20s east of lake ontario with readings reaching well above freezing
over the far western counties. All in all though... Good weather will
be in place for holiday shoppers travelers.

Continued warm advection will be found across our forecast area
Friday night... As a southerly flow will deepen between the exited
surface high and an approaching 'storm system' over the ohio and
tennessee valleys. Clouds will increase and thicken over the region
ahead of this next system... But we should maintain our dry weather
through the overnight. In regards to temperatures... It will not be
nearly as cold... As the stronger southerly flow will guarantee that
temperatures will be a solid 15 deg higher than those from
thanksgiving night. Lows will range from the teens in lewis county
to around 30 near lake erie... And those should be experienced before
midnight with slowly rising temperatures during the wee hours of
the morning.

Conditions will rapidly deteriorate across the forecast area on
Saturday... As a complex frontal system and developing surface low
will push to the east across the lower great lakes and mid atlantic
region. A robust 50kt low level jet will combine with a little help
from some h25 jet dynamics to lift a deepening moisture field to
generate fairly widespread rain... Particularly over the western
counties. There will be the risk that some of the pcpn will start
off as a mix of sleet wet snow during the morning... But there is no
doubt that this will be a rain event with daytime basin average
rainfall forecast to range from a few hundredths across the north
country to as much as a half inch across the southern tier. Its
worth noting that the southerly flow should encourage a little
downsloping north of the nys thruway between buf and syr... And this
will help to hold down the rainfall numbers by some 20 percent. Not
a big deal though given the projected rainfall totals. It will also
feel somewhat milder with MAX temps generally in the low to mid 40s.

The complex system within a supporting negatively tilted trough will
continue to advance across the eastern lake ontario counties
Saturday night. This will allow the rain to become more widespread
in that area... While the steadier rain will taper off and end as
nuisance showers over the western counties. Again... The pcpn should
fall as liquid... So no winter related travel issues are anticipated.

A short lived ridge will quickly pass over our region on Sunday.

This will provide us with fair dry weather... Although a few leftover
showers will be possible early in the day for sites east of lake
ontario. It will be relatively mild... As the mercury will climb into
the mid and upper 40s for the bulk of the region.

Long term Sunday night through Wednesday
Later Sunday night and Monday an upper level trough of low
pressure will carry a storm system eastward, with the surface
low tracking across, or just to our south Monday. This system
will bring a return to unsettled weather, with thermal profiles
within this pacific sourced system suggesting that rain will be
the predominate p-type.

On Tuesday this upper level trough will become negatively tilted,
and a new surface low will emerge to the lee of the appalachians.

This new surface low will bring impacts along the east coast, with
lingering surface troughing back across wny continuing the threat
for showers... Of which most will be snow as much colder air aloft
wraps across the eastern great lakes. This colder air, with 850 hpa
temperatures dropping to -10 to -12c... Will likely yield bands of
lake effect snow... Which at this time may be downwind of the great
lakes on a westerly flow. However there is still some model
differences in the position of the upper level low and where it
forms a cut off... That will influence the surface wind direction.

Regardless there will be chances for lake effect snow through the
end of the period with temperatures again returning to below
normal, with highs Wednesday possibly remaining below freezing.

Aviation 10z Thursday through Monday
High pressure pressure centered across the upper great lakes sending
arctic air over the region. Northwest flow producing light lake
effect snow showers south and southeast of the lakes. Ceilings south
of lake ontario 25-35 hundred feet with skc at kart. Intermittent
MVFR vsbys within the lake effect snow showers. The high will
settle overtop new york state by this afternoon. This will end
the snow showers with widespreadVFR conditions.

Outlook...

tonight and Friday...VFR.

Saturday and Saturday night... MVFR ifr in rain showers.

Sunday... MVFR in lingering lower ceilings.

Monday... MVFR with rain showers likely.

Marine
Strong high pressure will steadily build southeastward and into our
region today. Winds will continue to diminish as the high moves
closer, with small craft advisory expiration times outlined
below.

As the high moves east and off the atlantic coastline tonight and
Friday, winds will turn southerly and freshen. This will direct the
highest waves into canadian waters, so small craft advisories should
generally not be needed. The one possible exception is extreme ne
lake ontario where conditions could potentially reach advisory
levels during Friday.

Buf watches warnings advisories
Ny... None.

Marine... Small craft advisory until 10 am est this morning for
loz042>044.
