Cold in Massachusetts, January 13 to 14, 2018

Area Forecast Discussion
National Weather Service Albany NY
353 PM EST Sat Jan 13 2018

.SYNOPSIS...
Bitterly cold conditions will continue through early next week,
in the wake of a storm system tracking into the Canadian
Maritimes. A clipper type system may bring some light snow to
the region Monday night into Tuesday.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...

...Wind Chill Advisories in effect overnight through Sunday
morning The southern Adirondacks, western and central Mohawk
Valley, the Lake George region, eastern Catskills, Schoharie
Valley and Helderbergs, Taconics, the southern Green Mountains,
and the Berkshires....

As of 345 PM EST, a persistent area of snow showers continues
across the northeast/east portions of the Capital District,
extending north into the Saratoga/Glens Falls area, and
southeast through the central Taconics and Berkshires. This
seems to be associated with an area of enhanced low level
convergence, noted in surface wind observations, including those
from the NYS Mesonet, with a more north/northeast wind across
the upper Hudson River Valley through the Saratoga region, and
west/northwest closer to and within the Mohawk Valley (likely a
form of Mohawk-Hudson Convergence noted from CSTAR research).
Some moisture contribution from Lake Champlain also appears to
be involved. Localized snowfall amounts of 1-3 inches have been
associated with this feature this afternoon, and an additional
inch could occur through 5 PM.

This area should gradually dissipated this evening, with clear
to partly cloudy skies expected overnight. Very cold
temperatures, combined with some lingering wind, will produce
wind chill values of 15 to 25 below, if not slightly colder,
within the aforementioned advisory areas, which are mainly for
higher terrain areas with the exception of the western/central
Mohawk Valley.

Actual temperatures are expected to drop to 10 to 20 below
acrossportions of the southern Adirondacks, and generally 5
above to 10 below elsewhere, coldest across higher terrain
areas, and also close to the Lake George region.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/...
Sunday-Monday, mainly clear but cold conditions are expected.
Some patchy high clouds may pass across the region late Sunday
night, and again during Monday. Expect Sunday high temperatures
to reach the single digits and teens for most areas, except for
some lower 20s within the mid Hudson Valley. Monday highs should
be slightly warmer, mainly in the teens for higher elevations
and lower/mid 20s across valley areas. For Sunday night,
lows should fall to between zero and 15 below for most areas,
coldest across the southern Adirondacks and Lake George/Saratoga
region. If skies remain clear all night, even lower temperatures
could occur.

Monday night, a clipper type system will approach from the Great
Lakes region. Increasing mid level isentropic lift should
support increasing clouds, with some light snow developing from
west to east across the region later at night, especially for
areas north of the Mohawk Valley, where an inch or two could
accumulate by daybreak Tuesday. Lows should be in the single
digits and teens.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
The period starts out on Tuesday with a weak area of low pressure
approaching from the Great Lakes and a positively tilted upper
trough from the Midwest. This system should at least bring a light
snowfall to much of the region Tuesday through Tuesday night.

As the upper trough tracks eastward into the Ohio Valley region
Tuesday night, some model differences appear in how deep and tilted
the trough becomes. This has implications for the duration of
snowfall possibly lasting well into Wednesday (ECMWF solution), or
ending Tuesday night (GFS/CMC). A trend that models agree on is a
lower potential for earlier phasing and rapid cyclogenesis near the
east coast. The GFS and CMC continue to show a progressive/weaker
solution, but even the ECMWF now depicts phasing occurring later in
time and farther north and east into coastal Maine. So while we will
still have to watch for a potential east coast cyclone, it appears
that the probability for significant system affecting our area
continues to become less likely based on the 12Z guidance. However,
there is still several days for this to change so we will continue
to monitor model trends. Temperatures will be seasonable on
Tuesday/Wednesday.

On Thursday, a trough passing through in cyclonic northwest flow
will result in scattered upslope/lake effect snow showers mainly
over the higher terrain areas. It will be seasonably cold and breezy.

Tranquil conditions with normal temperatures then expected for
Friday, as a weak ridge of high pressure builds in with rising
heights aloft as well. Above normal temperatures look to be on the
horizon for next weekend as upper level ridging builds over the
region.

&&

.AVIATION /21Z SATURDAY THROUGH THURSDAY/...
Low pressure will continue tracking into the Canadian Maritimes
through tonight, as high pressure builds across the region.

Flying conditions will mainly be VFR through Sunday, with the
exception of MVFR to occasional IFR for Vsbys and Cigs at KPSF
through around 20Z/Sat due to lingering upslope-induced snow
showers.

Surface winds will be northwest around 15 kt with gusts around
25 kt, with the higher gusts at KALB/KPSF. Winds will veer into
the north/northwest tonight into Sunday, as speeds decrease to
around 10 kt or less after midnight.

Outlook...

Sunday Night: No Operational Impact. NO SIG WX.
Martin Luther King Jr Day: No Operational Impact. NO SIG WX.
Monday Night: Moderate Operational Impact. Chance of SN.
Tuesday: Moderate Operational Impact. Chance of SHSN.
Tuesday Night: Moderate Operational Impact. Chance of SHSN.
Wednesday: Moderate Operational Impact. Chance of SHSN.
Wednesday Night: Low Operational Impact. Slight Chance of SHSN.
Thursday: No Operational Impact. NO SIG WX.

&&

.HYDROLOGY...
The Flood Watch remains in effect for all of east central New
York and adjacent western New England through 7 PM due to the
lingering threat of ice jams and ice movement on area
rivers/streams, due to our recent warm spell and bout of locally
heavy rainfall.

Runoff should continue to decrease through Sunday, so the threat
of new ice jams should diminish later tonight and Sunday.
However, there could still be some lingering issues as any
existing ice jams may tend to become frozen in place due to the
very cold temperatures expected over the next 2 days.

For details on specific area rivers and lakes, including
observed and forecast river stages and lake elevations, please
