Area Forecast Discussion
National Weather Service Taunton MA
236 PM EST Fri Dec 22 2017

* Updated Near and Short Term sections only *

.SYNOPSIS...
A series of weak low pressure systems tracking near southern New
England will bring a wintry mix through Saturday morning, which
will transition to rain from south to north. High pressure
provides dry and seasonable weather Sunday. A fast moving
developing coastal low may bring a brief period of snow except
possibly rain for RI and southeast MA to the region late Sunday
night into Christmas morning. A colder than average week ahead
into the following weekend during which time there's the
potential for another winter storm before the end of the month.

&&

.NEAR TERM /THROUGH TONIGHT/...
235 pm Update...

* Overall forecast on track with light icing for much of SNE.
* Flash Freeze Possible in NE MA and Boston early Sat morning.

Leaning heavily on high-res guidance for temperature/PoP trends
through this evening. Regional radar mosaic shows most of light
snow has lifted to our north, while we're starting to see light
snow and/or wintry mix developing in SNE due to increasing warm
advection aloft, and additional activity developing upstream
across eastern New York.

Light snow will re-develop along and north of Route 2 corridor
late this afternoon and this evening, while precipitation
farther to south should be more spotty in nature, and will
slowly transition to wintry mix or light freezing rain. Later
tonight, forecast soundings show drier air working into snow
growth layer, which should give us lull in steadier
precipitation and allow drizzle/freezing drizzle to dominate.

At same time, combination of warmer air coming in aloft and
leftover cold near ground is expected to produce areas of dense
fog, especially across interior valleys and in higher terrain.
May need to consider Dense Fog Advisories in later forecasts.

Later tonight, weak low pressure exiting Cape Cod Bay will cause
winds to back to N across much of eastern MA. This will cause
lower level cold air to drain back down along coast, including
Boston area and probably as far south as Providence and Taunton
as well overnight. This drop in temperature will produce light
icing from freezing drizzle and/or black ice. High-res guidance
shows this potential clearly and has been very consistent.

&&

.SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/...
Colder air will be slow to erode Saturday, especially across
interior, as winds remain light from N/NE. Steadier rain should
arrive first thing in morning which will result in freezing rain
for much of morning, if not into early afternoon before
temperatures finally rise above freezing. This looks to be
borderline icing situation for much of SNE, aside from north
central into interior NE MA where colder air will be tough to
erode or mix out. For these areas, though, ice accretion should
be limited to no more than 1/4 inch and main impact will be for
travel.

Farther south, main concern is how far north milder (50s) air
can get as warm front lifts toward south coast. Fairly large
differences among models but majority of them keep milder air
confined to south coast or even just Cape Cod and Islands. This
makes sense when looking at overall pattern, in which low level
cold air often wins battle, and this also has support from HREF
and other high-res ensembles.

Cold front sweeps across SNE Saturday night, bringing an end to
rain and eventual clearing as winds shift to NW.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
*/ Highlights...

 - Possible over-achieving warm temperatures on Sunday
 - Snow expected around Monday morning, but exact impact uncertain
 - Colder than average over the week, monitoring for any storms

*/ Overview...

Potential holiday winter storm followed by nudging colder air and
high pressure from the N/W along the SE periphery of which quick
moving coastal storms are possible into the end of December.

Omega block ongoing over AK into the Arctic, cold air is dislodging
and beginning to bowl S through a subsequent broad trof regime over
Central Canada into the N-Central CONUS wobbling into the NE CONUS
as waves rotate through the flow, either from Arctic source regions
or straight from the Pacific as the omega block cuts off. Thermal
gradient / baroclinic zone along the SE periphery, need to closely
watch as waves cascade through. Pitch and amplitude all important
factors with respect to cyclogenesis and whether we start to see a
back-up in storm traffic across the N Atlantic.

A lot of moving parts, likely issues with model forecast guidance
resolving individual waves, confidence is weighted towards ensemble
means. An average of mass fields incorporating climatology / analogs
as to possible outcomes, all of which will be outlined along with
timing and forecast thinking in the discussion below.

*/ Details...

Saturday night through Sunday evening...

Interrogating the airmass preceding a likely holiday winter storm.
Separation from Arctic air via clipper low over S-Central Canada
wedged ahead of CONUS continental surface high pressure provides an
environment of light winds. If cloud decks remain scattered - broken
then it's likely we'll overachieve on temperatures into the low to
mid 40s. But also a part of this discussion is the remnant snow pack
and ice from the Friday - Saturday storm. The N/W likely to remain
colder whereas the S/E warms into the 40s, have a preference towards
the 22.0z MET guidance.

Melt with consideration to surface dewpoints as clouds are on the
increase towards the evening, all of which will have implications on
evening into overnight temperatures towards Monday morning ahead of
the holiday storm system, defining a rain / snow line through the
sweeping storm as a N/NE isallobaric-ageostrophic component of flow
manifests during the day Sunday increasing into the overnight period
ahead of cyclogenesis and surface low pressure emerging off the Mid-
Atlantic. Absent cold Arctic high N/E in this instance.

Overall, cold front pushing out Saturday evening, last of the precip
mainly as rain pushing offshore. Quick breeze of NW winds then high
pressure quickly settles in as low-mid level heights are on the rise
out ahead of the negatively-tilting H5 trof and attendant vortmax
digging over the OH River Valley, rotating cyclonically towards the
NE CONUS.

Sunday evening through Monday...

Key here is the morphology of the potent shortwave with respect to
the offshore baroclinic zone left by the trailing cold front from
the Friday-Saturday storm system with consideration to the right
rear quadrant of the accompanying H3 jet streak. GEFS members have
pulled back to the W, closer to the coast, succinct with most of the
operational model guidance, however several members remain well off-
shore. And yet, interestingly enough, ECens members have pulled E
including its operational counterpart. Still a tricky and uncertain
forecast.

Yes, it looks like it's going to snow, but the potency and snowfall
amounts remain in question. The main H5 vortmax and parent surface
wave sweeping into the NE CONUS, an energy transfer towards the off-
shore baroclinic zone. Beneath broader diffluence and QG-forcing on
top of New England, the mean of the right rear quadrant of the H3
jet streak immediately offshore. An eye on deformation and whether
the system closes off at H85-7 with energy transfer, rapid deepening
with cyclogenesis, a nod to the speed of the storm center overall.

So thinking initial broadscale ascent of light snow ahead of the
negatively tilting H5 trof. No issue with ice in the column, perhaps
some low level dry air to overcome, otherwise light snow settling in
towards midnight. As the system cyclonically curves and begins to
deepen, thinking there is a measure of W-E low to mid level fronto-
genesis towards Monday morning yielding more moderate snow. However
thinking the tilt towards the NW quadrant of the H85-7 low occurs
further and quickly downstream as the low closes off, so it'll be
downeast ME and SE Canada that'll bear the brunt of this storm. In
other words the system doesn't phase, moves too quickly, lacking the
wrap around delivering warning level snows. Looking like advisory
level snows.

As to the dividing line between rain and snow, generally around the
I-95 corridor but a lot of wiggle room and uncertainty. More than
likely amounts are going to fluctuate leading up to the event given
2m temperatures preceding along with the track of the low. Soundings
during the event near isothermal, a wetter snow considered, colder
air advecting into the low to mid levels not until the storm has
passed and begun to rapidly deepen.

Climatology time ... last time is snowed more than an inch on 12/25
was back on 2002, a late day event that spilled into the 26th. BOS
observed 5.5 inches when all was said and done, Hartford 7.8 inches.
Prior to 2002, last time it snowed more than an inch was either 1978
in Hartford, 1974 in Boston, for Christmas day.

Monday night onward...

Quickly breezy behind the storm prior to high pressure building in.
Going to have to watch the SE periphery of which up against the off-
shore lingering baroclinic zone, as to whether additional storm
development as waves continue to rotate through the broader cyclonic
flow hugs closer to the coast. Likely to see some of the coldest air
of the season given airmass dislodging over the Arctic, bowling S/E,
reloading with energy continually being sheared S. Could be looking
at a possible ebb and flow pattern during these reload periods in
where warmer air is allowed to return N ahead of potential storm
systems emerging out of the sub-tropical branch of the upper-level
jet. A low confidence forecast.

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Short Term /through Saturday Night/...

18z update...Moderate confidence.

Light snow over central New England will begin to shift south
this afternoon, bringing MVFR/IFR and 1-2" of additional
accumulation to northern MA, mainly along Route 2 corridor,
before a transition to sleet and freezing rain later in day.

Elsewhere spotty light freezing rain and/or sleet is expected
through this evening, except on Cape Cod and Islands where
mainly rain is expected. VFR ceilings will lower to MVFR across
most of the area by late afternoon, with areas of IFR ceilings
developing this evening.

Tonight...

Widespread IFR/LIFR conditions in patchy drizzle, freezing
drizzle, and fog. Light icing is most likely across interior and
across NE MA, probably into areas around Boston toward daybreak.

Saturday...

Widespread IFR/LIFR likely for most of day. Freezing rain
across much of region Sat morning (except south coastal MA/RI)
gradually transitions to rain from south to north, and last in
deeper valleys across interior. Icing could be as much as 1/4"
across north central MA.

Saturday night...

Conditions improve as cold front crosses region, shifting winds
to NW. Gusts to 25-30kt possible.

KBOS Terminal...Moderate confidence in TAF. Main concern is
potential for light icing late this afternoon, and again toward
daybreak Sat as winds shift to N and temperatures drop to near
or just below freezing.

KBDL Terminal...Moderate confidence in TAF. Confined mention of
freezing rain to Sat morning, but freezing drizzle is possible
tonight, as early as 02-03z.

Short Term /through Saturday Night/...High confidence.

Issuing Small Craft Advisories for building seas tonight on NE
MA waters, and for Sat/Sat night on south coastal waters for
increasing winds and seas.

E/SE winds will back to N later tonight as weak low pressure
exits east of Cape Cod. Frontal boundary should remain near
south coast Sat, which will maintain E/NE winds on E MA waters
with increasing S/SW winds gusting to 25kt on south coastal
waters. Cold front crosses waters Sat night, bringing wind shift
to NW and gusts to 20-25kt.

Expect periods of rain tonight through Saturday night, though
there could be some sleet/snow mixed around Boston and Cape Ann
through this evening.

Finally, areas of dense fog may develop Saturday and Saturday
night, especially on south coastal waters.

Outlook /Sunday through Tuesday/...

Sunday: Winds less than 25 kt. Local rough seas.

Sunday Night: Winds less than 25 kt. Seas up to 5 ft. Rain
