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.

Synopsis
A low pressure system positioned just off the DELMARVA early
this morning, will track northeast to near CAPE cod by this
afternoon. This system continues to bring a moderate to heavy
snowfall to much of the region. The system will move into the
canadian maritimes this evening, with snow ending across our
area during the afternoon. Seasonably cold and mainly dry
weather is expected tonight through Thursday, with some lake
effect snow showers across the western adirondacks.

Near term until 6 pm this evening
As of 356 am est... Light to moderate snow continues to fall
across much of the region early this morning. Pockets of heavy
snow occurring in a few mesoscale bands across parts of
columbia, dutchess, berkshire and litchfield counties. These
bands line up well with cold cloud top enhancement on the
goes-16 clean infrared channel. Snowfall reports have been scant
overnight, but estimates based on nys mesonet water equivalents
are around 3 to 5 inches across much of the warning area, with
2 to 4 inches in the advisory area from around the mohawk valley
and capital district south and east thus far. Much lighter snow
is falling across the adirondacks. Based on where the mesoscale
bands have set up and current trends from the latest hi-res 3km
nam and hrrr, we plan on keeping the current headlines in place
without any changes. Some minor modifications were made to
snowfall totals based on obs and radar imagery showing where the
mesoscale bands are. Maximum reflectivity values of around
25-30 dbz indicate snowfall rates of around a half to one inch
per hour, with weaker rates outside these bands. The heaviest
bands are generally expected to remain within the warning area,
although a few could migrate into northern portions of the mid
hudson valley where some 6-7" totals are possible.

The steadiest snow is expected to continue through the morning
commute time, especially from the capital district south and
east. Snow will gradually taper off from west to east late this
morning into early afternoon. However, hints of hudson-mohawk
convergence noted in the model surface wind fields and forecast
reflectivity from the 3km NAM hrrr wrf-arw from around albany
north and east. So will linger mention of likely pops in these
areas with an additional half inch to inch of snow this
afternoon. Temperatures will be seasonable for mid january,
ranging from lower 20s in the northwest part of the area to
lower 30s in the southeast.

Short term 6 pm this evening through Friday night
A small ridge of high pressure will build in to much of the
region tonight, although well-aligned westerly flow and
conditional lake- induced instability will lead to some lake
effect snow showers across the western adirondacks. Snow showers
will be light and scattered, due to forecast low inversion
heights of only around 850 mb. Elsewhere, it will be partly
cloudy with temperatures near normal with single digits to lower
teens.

Similar weather expected for Thursday, as a flat ridge of high
pressure at the surface will be in place. The continued westerly
flow will result in scattered light lake effect snow showers
across the western adirondacks, but dry elsewhere. High
temperatures will be near normal in the 20s to lower 30s. Models
in good agreement with a fast-moving and compact short wave
trough moving through Thursday night. This will result in mainly
isolated to scattered snow showers from around i-90 northward,
with the greater coverage across the western southern
adirondacks. A quick half inch to one inch of snow is expected
in these areas.

More flat ridging across the region on Friday with mainly dry
conditions expected. Some light lake enhanced upslope snow
showers could linger into the western adirondacks, but most
areas will be dry. Tempertures will moderate slightly, with
generally upper 20s to mid 30s expected for highs. Tranquil
conditions in store for Friday night, with the flat ridge
remaining in place.

Long term Saturday through Tuesday
This period will mark a turn toward much above normal
temperatures... With highs mainly in the 30s and 40s each day,
with mostly upper 20s and lower 30s by Sunday and Monday
nights. With mid-january being albany's coldest time of the
year, on average, lows there are normally in the mid teens, with
highs around 30 degrees.

High pressure centered over the deep south will build up into
the mid-atlantic region. An east-west frontal boundary will stay
just north of our zones as low pressure over the center of the
contiguous u.S. Develops and tracks across the great lakes and
into southern quebec through Monday night, displacing the high
pressure and bringing a good chance of rain showers throughout
the area as early as Sunday night, which could start as snow. By
midday Monday, all areas outside of the high peaks of the
adirondacks will likely experience pure rain shower activity
ahead of a cold front which will move quickly east across our
zones Monday night. It will be overcast with low instability.

Only a modest decline in temperatures will be experienced behind
the front... To as low as near normal.

Aviation 09z Wednesday through Sunday
A double barrel low pressure system will continue impact the
area. The primary low over upstate ny has begun to weaken as
the secondary coastal low develops near delmarva. The coastal
low will become the dominate low as it deepens and moves south
of long island late this morning and quickly northeast of cape
cod by the afternoon with the steady snow tapering to snow
showers and flurries. The mesoscale band of snow is expected to
impact kpou and kpsf early this morning. There could be some
lingering snow across the capital district due to a brief period
of mohawk-hudson convergence into the afternoon.

Ifr and lower conditions through the overnight and morning hours
with an improvement to MVFR expected by early afternoon andVFR
by evening. Conditions expected to improve a bit quicker at kpou.

Light and variable to calm winds overnight and well into
Wednesday morning with a northwest flow developing at 6 to 10
knots shifting to the west in the evening.

Outlook...

Wednesday to Thursday: no operational impact. No sig wx.

Thursday night: slight chance of shsn. Friday to Sunday: no
operational impact. No sig wx.

Hydrology
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 over the next few
days. Warmer weather is not expected until the weekend.

In terms of precipitation, a moderate snowfall is ongoing for
much of the area into today, with heavy snowfall from the mid
hudson valley and taconics eastward across western new england.

Mainly dry weather is expected through the weekend except for
some lake effect snow showers well north and west of the capital
district.
