What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

A weak area of low pressure will move into our region from the
great lakes today, bringing some light snow. Then, a developing
coastal low pressure system will emerge off the DELMARVA this
evening and track northeast to near CAPE cod Wednesday morning.

This system is expected to bring a moderate to heavy snowfall to
much of the region tonight into Wednesday.

Near term through Wednesday
Winter storm warning issued for the northern and central
taconics, southern vermont, berkshires and litchfield hills this
evening into Wednesday afternoon...

winter weather advisory remains in effect for the rest of
eastern new york today into Wednesday afternoon...

as of 616 am est... Areas of light snow will continue across the
area early this morning, as weak low pressure approaches from
the lower great lakes. One batch of light snow deposited a
dusting to an inch across the mohawk valley, eastern
catskills,saratoga lake george region, as well as the capital
district. This batch is now moving into the berkshires and
southern greens in vt. Additional areas of light snow moving
into the mohawk valley and eastern catskills at this time. Weak
warm advection ahead of the low is resulting in the light snow.

The light snow will be more prevalent for areas south and east
of albany during the afternoon evening, due to the SW to ne
orientation of the upper trough and forcing associated with the
thermal advection. Snow amounts today expected to be only around
1-2 inches in most spots, although up to 3 inches is possible
across the foothills of the southern adirondacks due to a s-sw
upslope component. Still, this light snow will affect the
morning evening commutes with some slippery travel on untreated
roads with temperatures in the 20s.

More substantial snowfall is then expected starting this
evening into tonight, as a coastal low pressure system is
forecast to emerge off the DELMARVA and track northeast along a
baroclinic zone close to the nj long island coast. At the same
time, a positive tilt mid upper level trough will migrate
eastward across the lower great lakes and ohio tennessee
valleys. Model QPF varies, but are in generally good agreement
with the track of the coastal low. The ECMWF continues to
indicate greater widespread QPF compared to other sources of
guidance, but details due to terrain enhancement and shadowing
are more apparent in higher-resolution guidance such as the 3km
nam and href. So the highest confidence in warning level snows
are across western new england into the north central taconics
of ny, thus we have upgraded the winter storm watch to a

We are also expecting some mesoscale banding to potentially
develop overnight into early Wednesday morning with the pattern
closely resembling a laterally quasi-stationary band from recent
cstar research. Nam GFS continue to depict the area of greatest
850-700mb f-gen along coastal areas, which would imply banding
to set up to the north and west of the f-gen based on the cstar
research. Hi-res guidance not overly apparent in forecasting
mesoscale banding, but this will be something to keep an eye on.

For now, we will mention up to 1 inch per hour snowfall rates
in the warning area with 6-9 inches total snow in a 12-18 hour
time frame, but these totals would have to be raised should a
quasi-stationary band develop.

Outside of the warning area, we will maintain the winter
weather advisories for totals of 4 to 8 inches of snow from
around the capital district south and east across the catskills,
mid hudson valley and southern taconics. Light snowfall from
today included in these amounts, thus these totals will occur
over a 24-30 hour duration so we will hold with the advisory.

Generally 3-6 inches is forecast for areas north and west of the
capital district.

The morning commute Wednesday will be affected by the snow, as
moderate to heavy snow will still be falling, especially from
around the capital district south and east as the coastal low
approaches the CAPE cod area. Again, we will have to watch for
potential mesoscale banding, which would enhance snowfall rates
and storm totals. The warning advisory will go through mid-
afternoon Wednesday with the snow expected to end from west to
east. The steady snow should end before the evening commute
Wednesday, with just a few leftover snow showers possible.

Short term Wednesday night through Thursday night
A small ridge of high pressure will build in Wednesday night
providing mainly dry conditions. However, due to well aligned
westerly flow and borderline conditional lake induced
instability, there will be some lake effect snow showers across
the western adirondacks. Any accumulations should be light, with
shallow inversion heights of only around 850 mb are expected.

Temperatures will be near normal, with lows in the single digits
and teens.

Similar conditions should prevail on Thursday, with a flat
ridge in place and a westerly flow continuing. Again, some light
lake effect snow showers may affect the western adirondacks,
but dry conditions should prevail elsewhere. Snow showers may be
a bit more enhanced with greater coverage Thursday night across
the western southern adirondacks, as a fast-moving short wave
trough is expected to move through. Still, only minor
accumulations are forecast with mainly dry conditions elsewhere.

Temperatures will remain near normal during this time.

Long term Friday through Monday
Gradual upper ridging building into the region into the
beginning of next week. Intervals of clouds Friday trending to
mostly cloudy by Sunday as warm advection strengthens. Strong
upper energy approaches Monday with rain moving in Sunday night,
expanding in coverage Monday.

Temperatures are a bit uncertain as some guidance has stronger
upper ridging than other guidance, which will determine where a
west-east oriented boundary layer thermal gradient sets up, just
north, across or just south of our region. Too far out in time
to know for sure, so blending guidance temperatures until we get
closer to next week. There could be some mixed precipitation
Sunday night before the strongest warm advection spreads into
the region Monday.

Highs Friday in the 30s with some mid to upper 20s northern
areas. Highs Saturday and Sunday in the 40s but mid to upper 30s
northern areas. Highs Monday in the 40s with upper 40s south
and lower 40s north.

Aviation 12z Tuesday through Saturday
Some patches of light snow are tracking through the area but it is
not a widespread uniform area of snow. There are breaks between
patches of snow but based on satellite and radar trends, there will
be intermittent light snow through this morning and indicating tempo
at all sites with MVFR ceilings and visibilities.

Steadier light snow is still expected by early afternoon but the
most intense snow rates are not expected until late this afternoon
and evening. Indicating MVFR ceilings and visibilities in the
steadier snow this afternoon with tempo ifr visibilities and
borderline ifr ceilings, basically 18z-23z. By 23z-24z heavier snow
should affect all TAF sites and continue all night with ifr
visibilities and borderline ifr ceilings.

Winds through mid morning will be light and variable, becoming
southerly at around 5 kt during mid morning through the rest of the
day and through tonight.


Tuesday night: moderate operational impact. Sn likely. Wednesday: no
operational impact. Sn likely.

Wednesday night: no operational impact. No sig wx.

Thursday: no operational impact. No sig wx.

Thursday night: no operational impact. No sig wx.

Friday: no operational impact. No sig wx.

Friday night: no operational impact. No sig wx.

Saturday: no operational impact. No sig wx.

Ongoing flooding due to ice jams will continue to be addressed
with areal flood warnings. There could still be some lingering
issues as any existing ice jams may tend to become frozen in
place due to the continued cold temperatures expected over the
next few days. Warmer weather is not expected until the weekend.

In terms of precipitation, a moderate snowfall is expected for
much of the area from today into Wednesday, with heavy snowfall
from the northern and central taconics eastward across western
new england.
