Synopsis
A cold and quiet start to the day will have morning sunshine
replaced by increasing cloud cover from the west. A deepening storm
system will pass by our region tonight, spreading occasional light
snow across the region that will amount to an inch or two. A
significant storm will then impact the region over the weekend with
the potential for heavy snow, significant blowing and drifting snow
to be followed by bitterly cold wind chills and areas of lake effect
snow.

Near term through Friday
Lake effect clouds continue to linger across wny this early morning,
with a flurry before daybreak along the southern lake ontario
shoreline. Drier air pushed across the lakes by a surface high
pressure that is centered just to our west will erode the lake
clouds this morning. Otherwise it will be a seasonably cold start to
the day with areas of sunshine outside of these lake clouds.

Later today a storm system will form across the ohio valley,
deepened by a shortwave trough that will sharpen the upper level
trough over the northeast. Ahead of this surface low clouds in the
mid levels will begin to increase through the day.

The falling heights aloft, coupled with the surface low and its'
associated moisture passing over the eastern great lakes will bring
occasional light snow to our region... Beginning during the early
evening hours across the western southern tier.

Light snow, may become enhanced to the northeast of the great lakes,
late tonight off lake erie and Friday morning off lake ontario. Even
so, snowfall totals will range between an inch or two across much of
the region from this little storm system.

Warming through the mid levels tonight, combined with an overcast
sky through the night will limit the amount of overnight cooling,
with many areas remaining within 5 degrees of their daytime high.

This surface low will push a cold front across the eastern great
lakes region Friday morning.

Behind the surface low, cold air advection will lower temperatures
in the boundary layer enough to bring back some light lake effect
snow... Falling to the south and southeast of the great lakes
tomorrow afternoon. This light snow is not expected to amount to
much, generally a few tenths through the afternoon hours on top of
the synoptic snows.

Short term Friday night through Saturday night
High pressure will move across ontario and quebec provinces Friday
night. A surface ridge will extend down into the eastern great lakes
at this time promoting mostly dry and calm conditions across the
region. Low-level winds will pivot around to the northeast overnight
and as cold, northerly flow persists, any lake effect clouds
and flurries will transition to the southern shore of lake
ontario by Saturday morning. Cold temperatures expected Friday
night with lows in the teens to near zero east of lake ontario.

Our eyes shift to the next big winter storm that has the potential
to bring heavy snow, gusty winds and bitter cold wind chills to
western and north central ny this holiday weekend. A mid-level
trough will track across the central plains while surface low
pressure deepens across the mississippi valley. Two important
strengthening jet streaks, one across the eastern great lakes
and another across the southeast will promote cyclogenesis as
low pressure moves northward into the central appalachians by
Saturday night. Light snow will likely move into western ny as
early as Saturday morning as strong warm air advection occurs
while a light easterly flow remains at the surface. This
snowfall will likely be a non-impactful with only a few inches
occuring through the day on Saturday. Temperatures will not
rebound much on Saturday with highs in the low 20's across
western ny to the single digits east of lake ontario.

There continues to be spread in the surface low track among mid-
range guidance with the 12z ECMWF further south than the 12z GFS and
gefs members. On the contrary, solid consensus between the
various medium range guidance packages then track the deepening
sub 1000mb low across virginia to roughly the DELMARVA peninsula
by daybreak Sunday. While the main deformation zone with this
storm should line up over pennsylvania... Deep lift over our
region will still be provided Saturday night through both
h925-70 frontogenetic forcing and strong h25 jet support. Since
h85 temps over lake ontario will be in the vicinity of -12c...

the counties that line its south shore will also receive
significant lake effect enhancement as the steering flow will
back from 060 to about 020. Temperatures will fall into the
single digits Saturday night with wind chills falling below
zero.

While it is still too early to pinpoint snow accumulations,
greater than 7 inches in 12 hours is possible. A winter storm
watch is in effect for Saturday through Monday.

Long term Sunday through Wednesday
A major winter storm with significant impacts expected this
weekend...

we will be in the midst of a major winter storm with significant
winter weather impacts on Sunday.

The winter storm will still be deepening on Sunday as it moves
off the new england coast. Steady snow continuing areawide
Sunday morning will shift away from the area during the day, as
we transition to the lake effect portion of the storm. The
coldest air this winter season will be drawn down into the
region on the backside of the storm and bring lake
enhanced effect snows to the region through Sunday night. This
could bring significant additional snowfall totals, especially
to areas south and southeast of the lakes, including the
rochester metro area. Strong northerly winds on the backside of
the storm will result in significant blowing and drifting snow
likely creating difficult if not impossible travel conditions in
many areas. Dangerously cold wind chills are also likely,
dropping to 15 to 25 below zero for most areas and perhaps as
cold as 30 to 40 below zero for the north country.

The powerful winter storm will exit across the canadian maritimes by
Monday, as a large arctic high crosses into the upper midwest great
lakes. A deep north to northwest flow between these features will
maintain a very cold north-northwest flow of air with 850 mb
temperatures nearing -26c. This brutally cold airmass will most
certainly support more lake effect snow showers, particularly
south and southeast of the lakes along with dangerously cold
wind chills.

Significant spread in long range model solutions exists for the
midweek time frame. Signal is evident for recovery of
temperatures to closer to normal values as the arctic air
departs Tuesday into Wednesday, but the development of a trough
in the central CONUS is causing some issue. The euro and gfs
both advertise low pressure developing and moving up the ohio
valley into the eastern great lakes, while the canadian has a
clipper-type low swinging through the region. Timing differences
also exist between each solution, but the Wednesday time period
currently appears to be the best timing for the arrival of
precipitation from this system. Some warmer air gets pushed
northward toward the region on the southern end of the
precipitation shield, but for now will keep the precipitation
type as all snow until more consensus in guidance is achieved in
the coming days.

Aviation 09z Thursday through Monday
For the 06z tafs, lake effect MVFR-based clouds linger across
portions of wny, and these should continue to thin as surface high
pressure to the west funnels drier air across the lakes. Mid level
clouds will continue to increase through the day, with the next
system and it's lower deck of clouds and snow likely to arrive early
evening to the far west. This system will pass across the region
with occasional ifr flight conditions within snow.

Outlook...

Friday morning... Areas of ifr in periods of light snow.

Friday afternoon and night...VFR MVFR with a chance of snow showers.

Saturday..Deterioration to ifr with widespread snow developing.

Saturday night and Sunday... Widespread ifr in heavy snow.

Monday... Local ifr in lake effect snow showers southeast of the
lakes.

Marine
High pressure just to the west of the lakes, has now brought much
lighter winds and minimal waves to the lakes this early morning.

These quiet conditions are expected to continue through Thursday
night with warming aloft ahead of a storm system that will bring
some light snow. Behind this system, winds and waves will increase
Friday night with small craft advisory conditions possible, mainly
on lake ontario. A strong storm system will pass by just to the
south of the lakes this weekend, with strong east winds backing to
northwest through the weekend and into next week with high end small
craft conditions expected.
