Area Forecast Discussion
National Weather Service Taunton MA
647 PM EST Wed Dec 13 2017

.SYNOPSIS...

 * Update on present winds in the near-term ...

A fast moving low pressure will track S of New England late
tonight and early Thursday bringing a period of accumulating
snow to the south coast and especially the Islands. Cold
persists into the weekend with a chance of snow showers Friday
night into Saturday. Blustery and cold for Sunday but the
beginning of a milder trend Monday ahead of which there's the
possibility of a mixed wintry precipitation event. Quiet and dry
with an ebb and flow pattern during the week up till late
Thursday into Friday during which time there's the possibility
of another mixed wintry precipitation event.

&&

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

7 pm update...

Light snow associated with a clipper low fast approaching. From
the SPC mesoanalysis, modest low-level frontogenetical push ahead
of the storm yielding some decent output as discerned via local
WSR-88D radars. Associated deep moist convergence on the backside
with elements over-running ahead along the leading warm front,
beneath strong ascent per main vortmax and parent H2 jet streak
aiding with divergence aloft (H85-2 differential divergence).
Decent warm air advection, can even see a nose of steep mid-level
lapse rates sneaking into the OH River Valley.

But downstream, the cold, dry airmass in place, low surface dew-
points holding firm, keeping both the surface low and better
moisture fetch well S offshore. Limitations on what can be lofted
N of the low and as to the potential of that being lofted in
reaching the ground. Nevertheless, do expect snow to move in
beginning around 4a, the height around 7a (9z-12z). Reductions
to visibility with light accumulations, the greatest of which
around 1-2 inches confined to the S-coast and across the Islands,
the Islands likely seeing the most.

Potency of the system will need to be monitored closely as we go
through the evening into the overnight. Have adjusted the forecast
bringing PoPs up to highly likely. Echoing the prior forecaster,
increasing clouds, snow settling in, at first appearing on radar
to be overspreading the region, but likely initially not reaching
the ground until a little later, closer to daybreak.

As to winds ... holding onto the WIND ADVISORY. Still seeing peak
wind gusts this hour that are actually at their strongest of the
day in some spots, close if not exceeding 45 mph (40 kt) criteria.
Vertical wind profilers from our radar and TDWR in Boston has
H925 winds out of the west in excess of 50 mph (45-50 kts observed).
Upstream winds are diminishing, so will continue to evaluate as
to whether headlines need to be dropped or extended.

Previous discussion...

CAA continues across southern New England with SPC mesoanalysis
indicating -19C air at 850 mb upstream over northern portions of NY
and VT. Thus modified arctic air continues pour across the area on
blustery WNW winds up to 45 mph, courtesy of 975 mb low over New
Brunswick. This will result in very cold conditions this evening
along with bitterly cold wind chills.

Fairly robust mid level trough currently over the Great Lakes races
eastward overnight with increasing clouds and light snow/flurries
developing toward daybreak especially across CT, RI and south of the
MA pike in western part of the state. Initially airmass is very dry
so while radar may look impressive late tonight probably a few hours
of virga before snow reaches the ground toward daybreak Thu.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...

*** Accumulating Snow Likely Immediate South Coast and Islands
 Thursday Morning ***

4 PM update...

Thursday...

Mid level trough moves across the region from west to east during
the morning. Good synoptic scale lift associated with this system as
seen on Q-vector maps. This results in surface low jumping from near
Cleveland at 06z to redeveloping south of Long Island 12z Thu and
tracking east along the 40N parallel during the day. Good model
agreement that modest omega (15 -ubar/s) occurs in the DGZ (snow
growth layer of -10C to -20C) 12z-15z Thu along the immediate south
coast and Islands. Thus should see at least modest size flakes
(dendrites) which will help reduce vsby and yield an efficient snow
system with 15-1 snow ratios. In addition, models suggest some
instability in this layer too in the form of -epv. So the
combination of modest synoptic scale lift, good Fgen in snow growth
layer may result in this system over performing. However limiting
factors for more snow is very dry airmass on the front end of this
system. Will likely lose a few hours of qpf to virga as blyr slowly
saturates. Furthermore, system is very progress which leaves just a
1-3 hr window for moderate snowfall. Thus have leaned toward a 1-3
inch snowfall for immediate south coast and islands with impact to
the morning commute from Westerly to Newport to New Bedford to Cape
Cod. Given cold antecedent conditions snow will immediately stick to
all surfaces. Will have to see how 00z models trend as these systems
sometime trend northward. This would result in accumulating snow
possibly as for north as Hartford to Providence to Plymouth.
Nonetheless there will be a very sharp cutoff on the northern edge
of the snow shield.

Given trough is very progressive expecting sunshine to develop
during the afternoon. Still colder than normal with highs only in
the upper 20s and lower 30s. Not nearly as windy as today but still
a chilly day.

Thursday night...

Becoming blustery during the evening behind departing low. However
winds drop off late as weak high pres builds in. This will allow for
another cold night including the south coast given a fresh snow
cover. Lows in the teens most areas with single digits well inland.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...

*/ Highlights...

 - Light snow showers possible Friday night into Saturday
 - Cold and blustery Saturday night into Sunday
 - Possible mixed precipitation Sunday night through Monday night
 - Perhaps quiet, cold until Thursday night into Friday
   with another mixed precipitation event

*/ Overview...

Interpreting through late December. Considerable forecast warming in
the stratosphere, polar low / night-time jet displaced to the other
side of the N hemisphere subsequent of noteworthy anomalous ridging
across Northern N America. Beneath which warm air continues to surge
into the Arctic from the NW Pacific (with perhaps MJO contributions)
and the NW Atlantic displacing colder air S where it becomes bowled
up across NE Asia / NE N America. Ensemble means continue to signal
an active weather pattern with an amplified H5 ridge-trof pattern
over the CONUS, anomalous H85 T warming over the N Pacific with cold
anomalies continually reloaded over Central/E N America, however a
trend towards higher heights / surface mean sea level pressure with
stratospheric cross-polar flow shifting into NW Europe.

Making sense of it all, NW Pacific disturbances translating E across
the CONUS seemingly look to flatten the H5 pattern, lock colder air
N for a time, the NE CONUS falling into the transitional zone of air-
masses before colder air reloads and surges S again. An ebb and flow
setup however not barred from N shots of colder air, the lack of S-
stream dominance. Yet a trend of higher heights as signaled from the
ensemble means, cold shots may not be as deep, storm development may
not be so pronounced long-term. Perhaps La Nina signals are starting
to emerge across N America with a lesser pronounced H5 trof pattern
over Central/E N America downstream of stout ridging / warmth over
the NW Pacific.

Tough to get down on the details and specifics, taking a broad view
approach with the discussion above. Will hit on any threats/impacts
in the details below. With perhaps a flatter pattern evolving and
the lack of downstream traffic over the N Atlantic, the move into a
zone of transition between the airmasses as noted above, as forecast
guidance suggests, could end up in a regime of quick-moving systems
with mixed precipitation type outcomes that later deepen downstream
and yield that reloading shot of colder air, yet that colder air not
as deep, perhaps simply swiping the NE CONUS more to the N.

*/ Discussion...

Friday through Saturday...

Cold, blustery at times, chance of snow showers Friday night into
Saturday. A nod to ensemble means for 24-hour rainfall probabilities
in excess of 0.01 inches as N-stream clipper energy translates to a
dominant S-stream disturbance across the offshore baroclinic front.
Yet leaning very light outcomes. Lack of ascent within moist snow
growth regions parent with the positively-tilted H5 trof undergoing
neutral transition along the surface transition boundary. It isn't
till better mid-level curvature and ejecting vortmax above the S-
stream can get things going, in this instance further downstream.
Leaning snow accumulations along the N/W slopes of high terrain
given orographic support, and along the SE coast as energy / ascent
begins to come together before ejecting out to sea. Highest snow
accumulations possibly over an inch for S/SE coast, especially over
the Islands and Outer Cape. Visibility impacts, perhaps some slick
road conditions. Behind the disturbance, winds kick up, colder air
drives back in, wind chills drop back down into the single digits
Sunday morning, lows in the teens.

Sunday into Monday...

Potential mixed precipitation event. Ascent overall light, seemingly
quasi-parallel flow along the lifting warm front. Above a cold air
damming signature with an indication of northerly ageostrophic flow,
the surface high to the N however a weaker low over the Great Lakes,
could see a period of freezing rain / drizzle centered around late
Sunday night into early Monday morning, especially in the interior
sheltered valleys where cold will be more difficult to dislodge. A
nod again to ensemble mean for 24-hour rainfall probabilities in
excess of 0.01 inches which is roughly 70 percent or greater. Again
light outcomes but enough to potentially make for hazardous travel
and could yield WINTER WEATHER ADVISORIES for a trace of ice. Some
question as to how quickly the warm front will lift N and how long
threats / impacts may linger. Could hold through Monday evening. A
low confidence forecast given poor handling via operational guidance
on individual upstream waves.

Tuesday onward...

Leaning a flatter, progressive flow regime with transitioning air-
masses. With any additional waves will be looking for potential
mixed precipitation events with the ebb and flow of 2m temperatures.
Weaker energy ejecting E and deepening, expecting behind each system
the return of colder conditions ushered by breezy N/W winds. Lack of
confidence in the forecast beyond 96 hours (which does include the
Sunday into Monday timeframe). In leaning with ensemble means, after
the early week disturbance, our next event may not occur until late
Thursday into Friday, an initial cold blustery pattern transitioning
warmer, more seasonable in-between.

...Accumulating Snow Likely Thursday morning South Coastal
Massachusetts and Rhode Island, including Cape Cod and Islands...

Light snow will overspread Connecticut, Rhode Island and southeast
Massachusetts between 4 AM and 7 AM. A band of moderate snow will
likely then develop between 7 AM and 10 AM along the immediate
south coast and islands, then quickly moving offshore by midday
with dry weather to follow.

This band of moderate snow will likely result in snow accumulations
of 1-3 inches along the immediate south coast of Massachusetts
and Rhode Island, including the islands. Given the timing and the
cold airmass over the region roads will quickly become snow
covered and impact the morning commute from Westerly to Newport
to New Bedford to Cape Cod.

Farther north snow intensity will decrease with just light snow or
flurries across the remainder of Connecticut, Rhode Island and
Massachusetts, with little if any snow north of the Mass Pike.
However there is some uncertainty how far north the accumulating
snow shield will track. There is a low probability that
accumulating snow could reach Hartford to Providence to Plymouth.

Stay tuned to later forecasts for any possible changes.
