Synopsis
This evening, variably cloudy with some isolated to scattered
light snow showers and flurries, especially over the higher
terrain. For Tuesday, a few snow showers are possible over the
hills west of the hudson river, but it will be mainly dry as
high pressure builds in. On Wednesday, fair weather is forecast
as temperatures moderate to above normal during the afternoon.

The next chance for widespread rain and snow will be Wednesday
night into Thursday.

Near term until 6 am Tuesday morning
As of 715 pm edt, a line of snow showers, some locally heavy,
continues to track east across schoharie county. Latest radar
trends suggest it is slowly weakening, but still expect a brief
burst of moderate-heavy snow across i-88 in schoharie county,
with additional bursts of snow into portions of northwest greene
county, western schenectady county and western albany county.

The snow showers should weaken upon entering lower elevations
further east, but still can not rule out some snow showers or
flurries within portions of the capital district through this
evening.

Otherwise, an upper level short wave and associated cold pool
will approach northwestern areas late tonight with some
additional cloudiness and a few light snow showers. Elsewhere,
diurnally-formed clouds should tend to erode a few hours after
sunset.

Lows tonight from the single digits across the southern
adirondacks to the 20s in the hudson valley and across southern
litchfield county.

Short term 6 am Tuesday morning through Wednesday night
Tuesday... West to northwest flow continues aloft and model rh
fields show at least partly sunny skies, as sfc high pressure
begins to ridge in from the oh valley. Cold air aloft and the
wind flow is aligned downwind of lake ontario so snow showers
are forecast across the western adirondacks, western mohawk
valley and northeastern catskills. H850 temps will be in the -8c
to -11c range. Highs will be in the upper 30s to mid 40s in the
valley locations, and upper 20s to mid 30s over the higher
terrain.

Tuesday night into Wednesday... The sfc high crests over the
region with generally clear skies and light winds. Radiational
cooling will allow for another cold night. Tue night lows in
the teens and 20s. The return flow with the retreating sfc high
and low- level warm advection will boost temps to normal to
above normal reading levels for wed. Mid and high clouds will be
on the increase ahead of a warm front, and a shower may graze
far northern herkimer county before sunset. In the warm
advection pattern, highs will reach the upper 40s to lower 50s
in the valleys, and upper 30s to mid 40s over the hills and
mtns.

Wed night... A sharp but positively tilted upper level trough
will move towards the region. Timing differences on how far east
precipitation reaches by daybreak thu. GFS is faster than
nam euro. Some rain or snow showers are possible in the
southwest flow ahead of a warm front. Some light wet snow
accums of 1-3 inches are possible over the southern adirondacks,
with a coating across the higher terrain elsewhere. Lows will
be in the upper 20s to mid 30s across the region.

Long term Thursday through Monday
The period starts out on Thursday with an upper level trough
expected to track eastward across the region. Cyclonic
vorticity warm advection ahead of the trough axis will bring a good
chance of rain snow showers, with diurnal orographic effects having
an impact on precip type. Any snow accumulation during the day
should be confined to mountain areas and minor due to expected light
qpf. Temperatures should be near normal, with highs mainly in the
40s for valleys, and 30s across higher terrain.

Forecast confidence then decreases by Thursday night, as additional
disturbances interact with the upper level trough that will be in
place over the region. Models continue to suggest coastal
cyclogenesis along the mid atlantic coast before tracking north to
northeast, with the 12z 18 ECMWF showing a deeper upper level trough
and closer track with the coastal disturbance, while the GFS gem and
gefs remain slightly more progressive, although have trended closer
to the coast than recent runs. A closer track would result in
potentially moderate QPF for the eastern half of our area and
possible steady rain and or rain changing to accumulating snow.

However, as mentioned this still remains a low confidence forecast
until guidance can better resolve the many upper level features.

This will need to watched over the next few days.

The active pattern continues on Friday, as another upper level
trough digs southward from quebec into the northeast conus. This
system looks to bring another fairly significant push of colder air
late Friday into Saturday with below normal temperatures, gusty
winds and additional snow showers. This system is expected to move
out fairly quickly though, with dry weather returning by Saturday
night and continuing through at least Sunday. Temperatures could
warm to above normal levels Sunday afternoon, as high pressure
builds in along with rapidly rising heights aloft.

Monday should remain mild, although a strengthening low mid level
baroclinic zone will be developing overhead. This could lead to an
increase in cloud coverage, and may even allow for some rain showers
to develop by afternoon, depending on where the aforementioned
frontal zone develops. To the south of the frontal zones,
temperatures may spike to above normal levels, with 50s and 60s
possible for high temperatures, while remaining in the 40s to its
north.

Aviation 23z Monday through Saturday
A weak upper level disturbance will pass across the TAF sites
tonight, with high pressure building across during Tuesday.

Some snow showers may pass near or just south west of alb
through 01z tue. A brief period of MVFR ifr vsby could occur if
they reach the TAF site. Otherwise, expectVFR conditions
through Tuesday, with occasional CIGS of 5000-7000 ft agl,
mainly early this evening and again Tuesday afternoon.

West northwest winds 8-12 kt should decrease to less than 8 kt
shortly after sunset, and then become light variable later this
evening through mid morning Tuesday. West to northwest winds
will increase to 5-10 kt by late Tuesday morning and continue
into the afternoon, with a few isolated gusts of 20-25 kt
possible Tuesday afternoon.

Outlook...

Tuesday night: no operational impact. No sig wx.

Wednesday: no operational impact. No sig wx.

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

Thursday: high operational impact. Likely shra.

Thursday night: moderate operational impact. Chance of shra... Shsn.

Friday: moderate operational impact. Breezy chance of shra... Shsn.

Friday night: moderate operational impact. Breezy chance of shsn.

Saturday: low operational impact. Breezy no sig wx.

Fire weather
This evening, variably cloudy with some isolated to scattered
light snow showers and flurries, especially over the higher
terrain. For Tuesday, a few snow showers are possible over the
hills west of the hudson river, but it will be mainly dry as
high pressure builds in. On Wednesday, fair weather is forecast
as temperatures moderate to above normal during the afternoon.

The next chance for widespread rain and snow will be Wednesday
night into Thursday.

Most of the higher terrain remains snow covered. Tonight, max
rh values will recover to 75 to 100 percent by Tuesday morning.

The rh values will fall to 30 to 55 percent Tuesday afternoon.

Rh again recovers to 70 to 95 percent by Wednesday morning.

The winds will be north to northwest at 10 mph or less tonight,
and be from the northwest at 10 to 20 mph on Tuesday. Winds
become light and variable late Tuesday night.

Hydrology
No hydrology problems are anticipated through the next week.

Forecast liquid equivalent precipitation for the next 7 days is
one half inch or less. Forecast temperatures will generally be
near to below normal. Low temperatures are forecast below
freezing on most nights
the combination of low precipitation, low maximum temperatures
amd dew point temperatures below freezing should lead to
orderly snow melt and minor changes in river flows.

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.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
