Synopsis
As high pressure slides across the region today, a
developing storm will bring a wintry mixture to most of the region
tonight. This wintry mixture transitions to all rain on Sunday as
warmer air advances northward. Then a strong cold front along with
a strengthening storm north of the great lakes region will usher in
colder temperatures and powerful winds across the region Sunday
into Monday.

Near term until 6 pm this evening
As of 915 am est, high clouds will continue to stream across the
region today ahead of the next storm system taking shape in the
central plains. This should allow for some peeks of sunshine
through the high clouds this morning as temperatures warm into
the upper 30s to lower 40s by this afternoon. So have freshened
up the hourly temps to reflect recent obs with the majority of
the forecast on track for today.

Prev disc...

as of 630 am est... Enhanced nighttime GOES 16 microphysics
imagery continues to reveal a couple layers of clouds across
the region. The persistent stratus deck across portions of the
dacks and western mohawk valley is showing signs of moving
toward the north. This deck was below the subsidence inversion
seen in the hrrr rap forecast bufkit soundings this early
morning. By later this morning, enough mixing should commence
and allow for additional breaks in the overcast to occur across
these areas. Elsewhere, canopy of ci cs continue to stream
across the sky from west to east as southern plains system takes
shape. So as 1034mb surface high transverses the region, should
be a tranquil and seasonable start to the weekend as we climb
to around 40f for valley locations and 30s elsewhere under
partly-mostly sunny conditions.

Short term 6 pm this evening through Monday
Winter weather advisory for most of the region tonight...

high wind watch expanded to include most of the region...

as has been well discussed in previous afd's, a potent storm
will unfold and develop from the southern plains and quickly
track across the heart of the great lakes region. This
meteorological bomb will allow for downstream moisture transport
and isentropic lift to overspread all of eastern ny and western
ne tonight. Per thermal profiles and still some residual low
level ageostrophic flow from the north, seems our region will be
under the threat for a wintry mixture to evolve from southwest
to northeast tonight. As convection upstream is expected to be
quite robust (see SWODY1 for the moderate risk and slight risk
areas upstream), transport moisture disruption is possible. Href
depicts this notion as lighter QPF is expected across most of
the region. Exception to this will be across the dacks into the
southern greens were favorable upslope conditions are expected
with a bit more favorable QPF values. Regardless, thermal
profiles suggest the onset may start out as some light snow then
transition to periods of sleet and freezing rain. Per the href
ptypes, seems the higher terrain will be the most susceptible
for accumulation ip fzra and into the lake george and northern
saratoga region. Per coordination from wwd and surrounding
offices, snow accumulations of around 1 inch with up to one
tenth of an inch of ice. So difficult travel conditions with
winter precipitation tonight, especially on untreated surfaces.

Overnight lows with wet bulb processes would suggest lower 30s
for valley locations to mid-upr 20s elsewhere.

Into Sunday, strengthening southerly low level jet magnitudes
will allow for the thermal profiles to moderate above freezing
which will reduce ip fzra through the morning hours. Then
periods of rain and rain showers are expected until a dry slot
approaches during the afternoon hours. So pockets of drizzle as
well are expected as there could be a period of dry weather,
especially to the south of albany. MOS guidance for highs vary
quite a bit as the mav is quite a bit milder than the met. The
ecmwf MOS appears to be a nice compromise with highs mainly in
the 40s cwa-wide.

As great lakes low deepens further toward 970mb, potent cold
front crosses the region by early Sunday evening. The best
isallobaric rise occur to the north of the region, however,
gradient and wind magnitudes remain quite high across the
region. Per bufkit momentum transfer, 40-60 kts wind gust
potential along with mesoscale effects down the mohawk valley
are enough for us to extend the high wind watch for most of the
region. Cold advection will be strong as h850 temperatures go
from +2c to +4c down to -12c to -14c by 12z Monday. So the
transition to rain snow showers to all snow showers are
expected. Additional light accumulations of snow are possible
across the higher terrain, especially into the dacks where some
blowing of the snow is expected. Overnight lows mainly into the
20s with teens into the dacks as wind chills drop back through
the teens and single digits.

Monday, blustery... Gusty... Potentially damaging winds will
impact the region. In addition, lake effect snow will be ongoing
downwind of lake ontario where portions of the western dacks
and mohawk valley may experience additional accumulating light
snowfall. What does fall will likely be hard to measure with the
strong winds with blowing and drifting of the snow. As this
time, per the nam3km, seems the band(s) of snow will be drifting
southward through the afternoon hours as boundary layer flow
becomes more northwest behind a short wave passing through per
ncep model suite consensus. High temperatures Monday will range
from the lower 20s across the dacks to lower 30s for the hudson
river valley locations and NW ct.

Long term Monday night through Friday
Behind the departing storm system, strong cold advection will be
ongoing for Monday night through Tuesday. With much colder air
working its way into the region, a band of lake effect snow should
be ongoing off lake ontario. With the northwest flow in place, the
core of this band will be impacting central new york, but some snow
showers should make it as far east as parts of the western and
central mohawk valley, schoharie county and the eastern catskills.

Some accumulation is possible for these areas for Monday night into
Tuesday, but amounts should be fairly light.

Outside of the lake effect, it will partly to mostly cloudy and
colder. Lows will be in the single digits and teens and highs on
Tuesday will be in the teens and 20s. With the decent pressure
gradient still in place and plenty of mixing due to the colder temps
aloft, it will continue to be rather breezy. Some gusts over 40 mph
will still be possible for Monday evening, but should diminish
somewhat for later Monday night into Tuesday. Still, gusts over 25
mph will be possible, especially for areas of channeled flow and the
higher terrain.

The lake effect should diminish by Tuesday night, as a high pressure
area moving across the area lowers inversion heights. With clearing
skies and cold temps aloft (850 hpa temps as cold as -20 to -25 c),
it should be a cold night, with lows ranging from 5 below over the
adirondacks to the low teens in the mid hudson valley.

Next chance for some snow showers looks to be Wed into Wed night,
although latest model runs have been backing off this potential
somewhat. Northern stream shortwave looks to move from the great
lakes towards the northeastern us. However, moisture will be fairly
limited with the fast moving system and the latest ECMWF and many
members of the GEFS are now showing little snowfall. Will continue
slight chc and chc pops for snow showers, but these may be fairly
scattered in nature and may not add up to a whole lot based off the
latest guidance. Wpc still shows northern and higher terrain areas
with a 10% to 30% chance of 0.25" of liquid equivalent, which is
probably still fair for now. Highs will continue to below normal in
the teens and 20s.

Behind this system, another high pressure area will keep dry, quiet
and chilly weather in place for Thursday with a partly sunny sky.

Highs look to reach the low 20s to mid 30s, with the mildest temps
in southeastern areas.

As of right now, it also looks to remain dry for Thursday night into
Friday, although the next storm could approach as early as Friday
night. Models are still all over the place with the track and
evolution of this system, but will go with chc pops for snow and
rain for Fri night into the weekend with temps generally near normal
levels.

Aviation 14z Saturday through Wednesday
Vfr flying conditions are expected to continue through the day
today. Based off the latest IR satellite imagery, skies should be
bkn-ovc with thin high clouds in place through the entire day around
20-25 kft. Wind direction will be variable, but will generally
trend from the n-nw towards the s-se by later in the day.

Clouds will lower and thicken this evening as the next storm system
starts to approach. Ceilings will become overcast around 12 kft by
later this evening with a light southeast wind. Some light precip
in the form of a wintry mix of sleet and freezing rain will arrive
around midnight from south to north. Flying conditions will
initially lower to MVFR for both vsbys CIGS once precip begins.

Towards daybreak, flying conditions will be lowering towards ifr,
although p-type will generally be rain (best chance of some
lingering mix will be for kpsf kgfl). Winds will continue to be
light from a s-se direction, although 2 kft winds will be increasing
to around 30-40 kts from the SE by Sunday morning, so some llws may
become an issue.

Outlook...

Sunday night: high operational impact. Very windy. Chance of
shra... Shsn.

Monday: high operational impact. Very windy.

Monday night: moderate operational impact. Windy.

Tuesday: low operational impact. Breezy. No sig wx.

Tuesday night: no operational impact. No sig wx.

Wednesday: low operational impact. Slight chance of shsn.

Wednesday night: low operational impact. Slight chance of shsn.

Thursday: no operational impact. No sig wx.

Hydrology
No hydrological impacts are expected today. Another period of
wintry mixed precipitation is expected tonight before changing
to all rain on Sunday late morning into the early afternoon.

Rainfall is expected to continue through the day Sunday, with
total QPF amounts generally between half of an inch up to an
inch with localized higher amounts.

The rainfall, combined with warmer temperatures, will promote
snowmelt and some minor rises on area rivers. The latest mmefs
this morning continues to show no flooding at this time but
will continue to monitor.

Colder air moves back into the region late Sunday into Sunday
night with lake effect snowfall the main precipitation type into
Monday. Cold and mainly dry weather is expected for Tuesday, and
some light snow or snow showers for the mid week. Flows should
lower quickly, and colder than normal temps are expected for the
mid to later portion of the week.
