Area Forecast Discussion
National Weather Service Taunton MA
250 PM EST Mon Dec 11 2017

.SYNOPSIS...
Dry weather this afternoon will be followed by some rain on
Tuesday, which will begin as a period snow/ice across portions
of interior southern New England. A shot of arctic air follows
Wednesday and Thursday with a period of strong winds and
bitterly cold wind chills. Another low pressure system may bring
more snow to the region sometime in the Thursday night to
Friday night timeframe, if it tracks close enough to the coast.
Somewhat milder weather will arrive by the end of the upcoming
weekend.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

Long term discussion updated.

1 PM update...

Last of the solid cloud cover was exiting Chatham and Nantucket
at 1 PM. Otherwise just scattered daytime cumulus was the rule.
Already seeing some high level cirrus invading the Berkshires
ahead of the next system. Winds were slowly diminishing, but
still gusting up to 20 mph along the east coast. Temperatures on
track for highs in the upper 30s to lower 40s.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/...
*** Mixed Wintry Precip Event Late Tonight into Tomorrow ***

Setup...
Dual, unphased shortwaves will generate double barreled low
pres situation late Mon night into Tue. The leading wave is
currently sliding from Saskatchewan into the N Plains, while the
secondary wave slides out of Manitoba into N Ontario. The fact
that these remain unphased, allows the initial parent low pres,
developing the great lakes to transfer energy to a secondary
warm frontal low pres which will slide across central New
England or along Gulf of Maine. In either case, developing 40+
kt H92 LLJ will push fully into S New England Tue morning,
allowing a nose of warm air between 975-900hPa. This allows the
+2C isotherm to reach near the NH/MA border, using an average of
available guidance, with slightly cooler temps along the MA/VT
border. Given this, precip onset within overrunning ahead of the
warm front should start as mainly SN, but then gradually give
way to liquid precipitation from SE to NW, with a low risk for
mainly SN especially extreme NW MA and into the Berkshires.
Thermal profiles are tricky, with more on that below. Latest
trends are also slower as the unphased wave takes on a negative
tilt and low dwpt depressions take time to overcome tonight,
suggesting overall lower QPF than previous runs.

Thermal profiles...
While soundings mainly H85 and above remain below 0C, the nose
of warm air associated with the LLJ falls mainly in the lower
100hPa. Mean temps in this layer rise above 0C to about route
+2C between 12Z and 15Z Tue. Given the dwpt depressions, wet-
bulbing would suggest light SN at precip onset, Sfc temps are
likely to warm slower, thanks to a lingering snowpack. Areas
closest to coastlines could start as a frozen mix.. Not a
classic damming signature, but low lvl mass fields do show some
weak inverted ridging and mesoscale guidance does have light
drainage flow particularly in the CT valley and Worcester Hills.
In any case, this is a typical scenario where guidance warms
the sfc/2m temps too quickly. The transition to all liquid
should generally occur no later than mid day, except in the
higher terrain of NW MA, which could remain cool enough for
SN/frozen precip.

QPF/Snowfall/Ice...
As mentioned above, thanks to a dry column initially overnight,
timing of precip onset have slowed and the resulting overall
QPF is lower, totaling around 0.30-0.50 Given this, there may
be less SN at onset with some areas starting as RA/FZRA. The
warm influence also favors lower ratio snows, therefore, have
lowered expected snowfall through. The FZRA/SN thinking with
this update is backed up by latest WPC Day 2 data. Ice accums
would be light as the warm air should translate to the sfc
mainly a tenth or so at best, as sfc temps are not expected to
be marginal, and not in the 20s, in which ice accumulation is
more efficient. Snowfall totals are now lighter, with the best
chance for advisory lvl snowfall in the high terrain of NW MA,
where the low lvl warm air will be slowest to arrive, if it even
ever shifts above 0C. 3-6 inches is the latest forecast for NW
MA but with another set of guidance still to come, these are
still likely to change a bit.

Timing/impact...
Precip, likely mainly in the form of light snow, gradually
transitioning to a mix of FZRA and RA begins mainly after 1AM
from W to E during the early morning hours Tue, with widespread
precipitation likely between 7AM and 1PM, and continuing to
change form wintry precip to then gradually ending from S-N
mainly after 3PM through 7PM. The Tue AM commute has the highest
risk for impact, as SN or even a wintry mix could impact
portions of the commute as the warm air build in aloft.
Untreated sfc could become slippery thanks to a light SN accums
and/or light icing. By the afternoon commute, precip still
occurring, but mainly rain outside of the higher terrain of MA
particularly.

With all these factors, will hoist Winter Weather Advisories
for portions of western and central Massachusetts, where
confidence is highest in snowfall totals in the realm of
advisory levels, and the best chance for cold air damming
supporting some ice accumulations. These may need to be expanded
based on new data today.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...

Wednesday...

There is a chance of snow squalls continuing into Wednesday
morning as an arctic front progresses across Southern New
England. Very little snow accumulation is expected with these
passing showers, likely up to an inch at most west of the
Worcester Hills.

Winds will pick up in the afternoon as there is an impressive upper
level jet overhead. Models are in agreement with 40kts at 925mb
mixing down to the surface Wednesday afternoon. The GFS suggests
the strongest winds will be over the northern tip of the Cape
and extend into Mass Bay. Wind gusts between 40 to 50 mph are
not out of the question. Winds will likely peak by 00Z Thursday
as the upper level jet sits directly over the region.

Wednesday night temperatures will range in the teens due to the
arctic airmass now over the region. With the combination of the
arctic airmass and strong surface winds, wind chills are likely
to hover near zero degrees overnight. With minimal cloud cover
as well, radiational cooling will add to the low apparent
temperatures.

Thursday and Friday...

Strong winds will continue into Thursday morning but begin to
dissipate throughout the afternoon and evening.

Both the ECMWF and NAM point towards a weak system that brings
light snow to the islands and southern coast of New England
Thursday afternoon. The system will likely not linger off the
coast for very long, resulting in minimal snow accumulations, if
any at all.

The arctic airmass remains over the region through Thursday and
Friday resulting in much below normal afternoon temperatures. With
the winds diminishing by Thursday evening, wind chills should not be
an issue, however overnight temperatures will continue to range in
the teens across much of the region.

Friday night and Saturday...

A coastal low is expected to clip the region Friday/Saturday
resulting in periods of heavy snow along the 95 corridor.
Unfortunately, the models are not in agreement with timing or
position for when it does make its way up to Southern New
England.

Going with guidance from the ECMWF and NAM, precipitation will push
north across the region starting at 18z. As the low moves further
northeast, east of the 95 corridor will likely see the most
accumulation. The coastal low is expected to push offshore by
Saturday afternoon.

Sunday...

A ridge builds in Sunday morning behind the coastal low. Winds will
turn to the southwest, advecting warmer temperatures into the region
by midday. Dry and seasonable temperatures will continue through
early next week.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Short Term /through Tuesday Night/...

Through this afternoon...High confidence. VFR.

Tonight...Moderate confidence.
VFR to start, will give way to MVFR then IFR early AM Tue as
CIGS lower and light SN/FZRA moves in mainly after 06Z from W-E.
SN accums would be light. Winds shift around to the E-NE.

Tomorrow...Moderate confidence.
Mixed MVFR and occasional IFR conditions in a mix of SN/FZRA
giving way to all RA through sunrise into mid day Tue. Risk for
NW MA to remain SN long enough for accums to exceed reach 3-6
inches with generally less further SE. Low risk also for a
period of FZRA before the change to RA. Conditions improve after
20Z from S-N.

KBOS Terminal...High confidence in TAF.

KBDL Terminal...High confidence in TAF.
