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
A few lake effect clouds continue to linger near lake ontario
this 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 near lake ontario will
erode the remaining 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 Sunday night
On Friday night, high pressure will pass to our north which
will result in mostly dry conditions across the region. A
northerly flow will support some lake effect clouds or light
snow showers south of the lakes, but the air mass will be dry
with little if any accumulation.

A major winter storm with significant impacts this weekend...

low pressure centered near western kentucky on Saturday will track
into virginia Saturday night. This system will then intensify along
the southern new england coastline on Sunday as it phases with a
northern branch shortwave. The low will then strengthen to about
985 mb as it moves across nova scotia on Sunday night.

Despite the rather distant track of the surface low, a broad shield
of mid-level warm air advection will spread ahead of the system
Saturday and intensify Saturday night. The surface flow will shift
from NE to NW on Sunday, with 850mb temperatures falling to around -
25c. Steady synoptic snows will taper from west to east, but will be
replaced by lake effect and upslope enhanced snows south of the
lakes. Ample moisture should remain in place through Sunday night
when the passage of a mid-level trough. This trough will exit to the
east on Monday, with drier air diminishing lake effect snowfall
rates.

Model guidance is in good agreement considering the timeframe, but
there remains uncertainty in the track of the low. The main
challenge is exactly how quickly the southern branch system phases
with the northern branch. 00z guidance has come into better
agreement with model differences diminishing considerably. There is
now doubt this will be all snow in our area, with increasing
confidence that accumulations will be significant. It appears the
only way this storm can 'miss' is with a slower phasing and more
southerly track which appears unlikely but still possible. Based on
this, forecast confidence still supports watch headlines.

The impacts of this system can be divided into two parts. The first
is the synoptic snowfall which will start on Saturday and last
through Sunday morning. Initially, snowfall rates will be modest on
Saturday with just a general area of light snow spreading from
southwest to northeast across the region. The heaviest snow will be
Saturday night into Sunday with significant accumulation likely
across the entire region. In addition, winds will increase with
gusts to 30 mph resulting in areas of blowing snow along with cold
temperatures in the teens and single digits.

Synoptic snows will transition to lake effect snow Sunday afternoon
with a northerly flow supporting lake effect snow south of the lakes
through Monday. Snow will be more localized, but very small
snowflakes will lower visibility effectively. In addition, gusty
winds will result in areas of blowing snow, especially during the
day on Sunday. Dangerously cold wind chills are 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. Travel conditions will improve
modestly late Sunday night and Monday, but it will still be very
cold with high temperatures only in the single digits on Monday.

Snowfall amounts are difficult to pin down this far off. In general
terms, there is a potential for greater than 7 inches of snow across
the entire region. The greatest amounts are likely to be across the
western finger lakes lower genesee valley, which includes the city
of rochester. This is because of lake and upslope enhancement from
the northerly flow. Although some locations may get more than a foot
of snow, it is important to note that bitterly cold wind chills and
blowing snow will be a significant part of the impact of this storm.

Long term Monday through Wednesday
Significant spread in long range model solutions exists for the
midweek time frame. Signal is there 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 GFS and euro 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 12z Thursday through Monday
For the 12z tafs, lake effect MVFR-based clouds linger south of
lake ontario, 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.

Buf watches warnings advisories
Ny... Winter storm watch from Saturday afternoon through Monday
afternoon for nyz001>008-010>014-019>021-085.
