Synopsis
A weak disturbance will move across the region later today
which may bring a little light snowfall to the area, but
otherwise, expect dry conditions lasting into Sunday as surface
high pressure moves into western new york. A few more minor
periods of showers will be possible early next week, but dry
weather is expected for thanksgiving.

Near term through tonight
Precipitation type continues to be a challenge this morning,
with cloud tops marginally cold enough to support dendritic snow
growth. IR satellite shows cloud tops around -10c which is
likely to result in drizzle or showers. It's a few degrees c
colder east of lake ontario, with rain or snow showers possible.

Fortunately, surface observations show that temperatures have
risen above freezing late this morning. Because of this, the
winter weather advisory was allowed to expire.

Light lake effect rain or snow showers will continue off of
both lakes through mid afternoon. Expect little, if any, snow
accumulation from these. Mostly cloudy skies will remain for
most of the day today across the area. Cold air advection
starting in the afternoon along with cloud cover will limit
temperatures today. High temperatures today will average in the
mid to upper 30s across the area.

A weak disturbance moving across the area late this afternoon
and evening combined with some increased moisture, will bring
the potential for widespread light snow showers. Areas that are
cold enough for snow to accumulate, will get a light coating.

Tonight, scattered snow showers from the weak synoptic disturbance
will taper off, and transition to lake effect southeast of both
lakes. Lake effect snow off of lake erie will be light and only last
a few hours as winds shift to the southeast ahead of the next
synoptic system on Sunday, lake showers should end just after
midnight tonight off of lake erie. The same scenario will
follow for lake ontario, but about 6-10 hour longer. Off of both
lakes, up to around a half inch of snow will accumulate. Cold
air advection will continue through the night tonight before
weakening on Sunday morning. Low temperatures tonight will be in
the teens eat of lake ontario, and in the low to mid 20s from
the higher terrain to the lakeshores respectively.

Short term Sunday through Monday
Sunday morning some very limited lake effect may still be ongoing at
the southeast corner of lake ontario from eastern wayne to
southwestern oswego counties. Any scattered flurries or light snow
showers from this will end by mid morning as inversion heights lower
and shear increases. Our attention then turns to a weak baroclinic
wave forecast to run along a stalled frontal zone from ohio to pa.

Weak isentropic upglide and frontogenesis aloft to the north of the
surface frontal zone will allow a band of light snow to develop
across the western southern tier later Sunday through Sunday
evening with some minor accumulations possible. The northern edge of
this is forecast by most model guidance to stay south of buffalo and
rochester. Highs will be in the low to mid 30s in most locations,
with some 20s across the higher terrain east of lake ontario.

Light snow associated with the baroclinic wave will move south and
east of the area later Sunday evening. The airmass may be marginally
supportive of a limited lake response Sunday night behind this wave,
with southwest flow gradually veering more westerly overnight. This
may allow a few flurries or light snow showers to develop northeast
and east of the lakes, but continued low inversion heights should
keep this light if it does in fact develop. Lows will be in the mid
to upper 20s.

Monday the eastern great lakes will largely stay between systems.

The stalled frontal zone may continue to produce some light precip
across pa, with an approaching mid level trough and surface cold
front bringing snow showers to the upper great lakes and ontario
upstream of us. There may still be some very limited potential for
light lake effect rain snow showers east of the lakes, otherwise the
rest of the area will stay mainly dry. Highs will reach the mid to
upper 30s in most areas.

Long term Monday night through Friday
Temperatures will remain below normal through midweek as a longwave
trough remains in place across the northeast quarter of the nation.

A few more weak mid level shortwaves and associated cold fronts will
bring the potential for nuisance snow showers Monday night through
midweek, with limited lake effect potential at times. The first
such front will cross the area Monday night and early Tuesday with a
few scattered snow showers. Lake enhancement east and southeast of
the lakes may produce minor accumulations across higher terrain.

This will be followed by limited northwest flow lake effect later
Tuesday and Tuesday night. Another weak shortwave may cross the
region Wednesday and Wednesday night with a chance of a few more
snow showers.

Late next week into next weekend it still appears a pattern change
will bring a significant warm-up to our region. The details on when
the warm-up arrives continues to show a good deal of run to run
variation in model guidance. Model and ensemble consensus from
yesterday suggested thanksgiving would be the first warmer day.

Model guidance has now backed off on this idea, with a lingering
trough over new england through thanksgiving. In fact, the new 00z
ecmwf has another strong push of cold air arriving Wednesday night
and thanksgiving day. Given the model uncertainty, have trended the
forecast temperatures down for thanksgiving but not as far as
current model guidance. A warmer airmass will eventually arrive by
Friday or next weekend.

Aviation 15z Saturday through Wednesday
Bountiful moisture in the lower levels will maintain ifr or lower
conditions for most of today across higher terrain, including kjhw,
while lower elevations will be mainlyVFR with periods of MVFR.

This moisture will remain through the day, with conditions
improving some late this evening.

Ahead of another shortwave a band of weak snow over the so. Tier
this morning will begin to move northward along the long axis of
lake erie. This may bring a bit of light snow to kbuf and kiag late
this afternoon into the evening.

Sunday... MainlyVFR with high pressure. Possibly MVFR to the south
late.

Outlook...

Monday and Tuesday... MVFR ifr with a chance of snow showers.

Wednesday...VFR with high pressure.

Marine
Westerly winds will last through the day today with corresponding
small craft advisories. Surface high pressure will be overhead
on Sunday. A few weak systems may affect the waters Monday and
Tuesday, and surface high pressure overhead starting Wednesday
night.

Ny... None.
