Synopsis
Clouds will increase this evening ahead of an approaching
storm system that will bring snow, rain, sleet and freezing rain to
the region for late tonight through Saturday morning. Some areas,
especially northern and high terrain areas, may see significant
snowfall from this storm.

Near term /through Friday/
Quite a complex forecast with the incoming winter storm system.

However, for the rest of the evening, expect dry weather and a
continued increase in mid to high level clouds as the system
approaches. Temperatures this afternoon have reached the lower
40s to lower 50s but are expected to drop into the upper 20s and
lower 30s before precipitation begins.

Large scale pattern shows cut off low lifting slowly through
missouri with large swaths of precip and convection out ahead of
it. The piece of energy that is expected to bring us mixed
precipitation late tonight is currently lifting through northern
pa/western ny. Depending on how quickly it arrives, it could
briefly start out as rain but quickly change over to a snow up
north and a wintery mix south and west of the capital district.

This is due to a low level jet that is expected to develop out
of the south at 30-35 kts. A quick 1 to 3 inches of heavy wet
snow will be possible by the morning commute in many locations.

Cannot rule out higher amounts if enough cold air is trapped at
the surface as QPF amounts of up to 0.75" are possible by 8am
across the central portion of the forecast area.

A wintry mix of precipitation will continue throughout the day
tomorrow as a surface low develops off the mid-atlantic
coastline and moisture continues to get wrapped into the region
from the atlantic. The upper level cut off low will track to our
south throughout the day, continuing to wrap moisture into new
york. There is still uncertainty with the precip type as both
the gfs/ecmwf remain colder aloft (and bring us more snow) but
the NAM has been persistent with the warm air aloft (and mixed
precip). So have went with a blend of all three models for the
current forecast. This has prompted a winter weather advisory to
be issued for the entire area except the lower hudson valley
and a winter storm warning to be issued for windham county, vt
where 8 to 12 inches of snow is possible. The lower hudson
valley should see mainly rain, however, any heavier bursts of
precip could allow for snow or sleet to mix in or changeover
from time to time, as the heavier precip forces the temperature
profile to go isothermal.

Snow ratios will be poor, due to the wet and melting nature of
the snowflakes and the dendritic growth zone being so high up.

The heavy wet snow could result in some power outages. It's
still unclear how easily the snow will stick on roadways due to
the warmer ground temps and occurring during the daytime.

However, past late-season storms have shown that if snow falls
hard it enough, it will stick anywhere.

Short term /Friday night through Saturday/
Precip will continue through Saturday morning, as the secondary
surface low develops off the ma coastline. This should aid in
allowing the temps aloft to start to cool off, and end the
threat for sleet from north to south by Saturday morning. As
the storm starts to track away Saturday afternoon, just some
lingering rain and snow showers are expected, but the bulk of
the accumulation should be done by Saturday morning.

Valley areas could see up to 6 inches of snowfall, with 6 to 12
inches possible for higher terrain areas. However, with the
uncertainty of precip type, snowfall amounts could change. Stay
tuned to your national weather service for updates to the
forecast as the situation unfolds.

Long term /Saturday night through Thursday/
A parade of storm systems may bring flood concerns next week...

Saturday night lots of low-level moisture remains across the area as
low pressure is pulling away from new england and high pressure
starts to build in from north of the great lakes. Some residual snow
showers are possible, mainly across the adirondacks and southern
green mountains with lows in the 20s to around 30f.

High pressure controls the weather Sunday and Sunday night and then
moves east Monday. Highs Sunday in the mid 40s to around 50 but
around 40 higher terrain. Lows Monday in the 20s to around
30f. Clouds increase through the day Monday with the approach of
the next system. Highs Monday in the mid 40s to lower 50s.

Rain and mixed precipitation is expected to begin Monday night as
temperatures cool to the low to mid 30s. Strengthening warm
advection expected to turn precipitation to rain during the day
Tuesday. Highs Tuesday in the 40s to near 50. 12z euro further south
with track of system and Tuesday event looks much like event for
tomorrow (Friday) with lots of wintry precipitation. For now, will
stick with a model blend.

Precipitation coverage decreases Tuesday night through Wednesday
but isolated showers/snow showers possible with the gradual exit to
the system and gradual decrease in moisture. High pressure builds
to north of the albany forecast area so temperatures will remain on
the cool side. Lows Wednesday in upper 20s to mid 30s. Highs
Wednesday in the 40s and 50s.

By Thursday, yet another storm system, progged to take a similar
track to the previous two, may bring another round of wintry
precipitation and rain. Lows Thursday generally in the 30s with
highs in the 40s to around 50.

Aviation /19z Thursday through Tuesday/
Vfr conditions expected through this evening. By this evening,
thicker clouds and the leading edge of precipitation ahead of an
approaching area of low pressure are expected to move into our
region. By 06z-09z precipitation will begin, snow at kalb, kpsf and
kgfl but mainly rain at kpou with possibly some snow or sleet mixed
in for a couple of hours. Ceilings will lower to MVFR and
visibilities falling to ifr for a time in moderate snow at kgfl,
kalb and kpsf. Precipitation should remain all snow through 18z at
kgfl, but should transition to a mix of rain, sleet and snow at kalb
and kpsf by late morning.

Winds... North to northeast and light under 10 knots through this
evening. Winds generally light and variable tonight becoming
southeast at less than 10 kts on Friday.

Outlook...

Friday night: high operational impact. Definite ra... Sn... Sleet.

Saturday: moderate operational impact. Likely shra... Shsn.

Saturday night: no operational impact. No sig wx.

Sunday: no operational impact. No sig wx.

Sunday night: no operational impact. No sig wx.

Monday: no operational impact. No sig wx.

Monday night: moderate operational impact. Chance of ra... Sn.

Tuesday: moderate operational impact. Chance of shra... Ra.

Fire weather
Much of eastern new york and western new england continues to
have snow on the ground. Although snow melt has been ongoing
recently and most valley areas only have snow depth of a few
inches, much deeper snowpack remains across the hills and
mountains.

Precipitation is expected tonight through Saturday morning in
the form of rain, snow, sleet and freezing rain.

Hydrology
A series of storm systems will impact the albany hydrologic service
area during the next week. Forecast precipitation across the area
over that period is 2 to 3 inches liquid equivalent. Much of the
precipitation will be frozen Friday into Saturday. Precipitation
type is uncertain for the next event.

For the next 72 hours, the only river point forecast to reach flood
stage is the hudson river at poughkeepsie due to high tides. The
longer range multi-model ensemble river forecast system has a few
points reaching minor flood stage next week Tuesday into Wednesday
as the result of snow melt and additional precipitation.

For details on specific area rivers and lakes, including observed
and forecast river stages and lake elevations, please visit the
advanced hydrologic prediction service /ahps/ graphs on our
website.
