Area Forecast Discussion
National Weather Service Taunton MA
1257 PM EST Sun Dec 25 2016

.SYNOPSIS...
Dry and seasonably cool weather continues into early tomorrow,
with some rain and freezing rain approaching by late afternoon
from the west tomorrow. Any leftover freezing rain across the
interior changes to plain rain showers Monday night, with rising
temperatures and windy conditions developing on the coastal plain
late. Windy with unseasonably mild temperatures and perhaps some
lingering showers Tuesday morning, will give way to dry but colder
weather later Tuesday into Wednesday. Low pressure will likely
bring some snow/ice and rain to the region Thursday into Thursday
evening.

&&

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

Very strong high pressure over Ontario and Quebec will be moving
toward northern New England this afternoon. Northwest winds were
gusting to 15-30 mph with one report of a 40 mph gust at Beverly,
MA in the past hour. Expecting these winds to continue into the
mid afternoon hours, then diminish rapidly toward sunset.
Skies had become sunny across the entire region as of 1 PM.
Temperatures were holding steady in the mid 40s in the southeast
half of the region, but had begun to slowly fall in northern and
western MA, as cold air advection begins to overwhelm the low
December sun angle.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/...
Tonight...
High pres ridge noses over the region tonight, yielding a weaker
pres gradient. With clear skies, expect good radiational cooling
with temps dropping to the teens and low 20s around much of the
region. NW MA, where snowpack remains established some locations
could see mins in the single digits.

Monday...
Quiet start to the day with high pres across N New England sliding
to the N-NE as low pres approaches well from the W. Column does
show moisture loading, but mainly from H7 to the sfc through the
afternoon and evening, so in spite of the sunny starts, the end
of the day will be cloudy, with a risk for light overrunning
precip attendant to late day S LLJ 40-50 kt.

The combination of the cold start to the morning, high pres to the
N-NE yielding ageostrophic flow out of the N-NE through the
afternoon, sfc and 2M temps should remain quite cold in spite of
the LLJ allowing H92 temps to reach nearly +5C by 00Z Tue. Highs
will be limited to the mid 30s to around 40, with colder spots
dammed in the valleys of W MA/CT, likely near or below freezing.

Given this and the approaching precip shield which could be late
due to sfc-H8 dwpt depressions remaining around 10F or higher,
some freezing rain or even sleet is possible given the lowest
layers will remain below freezing well into the evening. Am
concerned about ice accretion given that the very cold temps from
Sun night will keep sfc temps below 2M temps. No advisories at
this time given the uncertainty in timing and strength of warming
with the LLJ, but this is a case where they may well be needed
with future forecasts should this risk hold.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Highlights...

* Any leftover interior freezing rain changes to rain Mon evening
* Showers w/rising temps Mon night and becoming windy on the coast
* Lingering showers possible Tue am, otherwise dry and windy
* Dry and turning seasonably cold Tue night/Wed
* Some snow/ice and/or rain likely Thu/Thu eve

Details...

Monday night...

Large high pressure continue to moves off the coast as strong low
pressure lifts well to our northwest towards Hudson's Bay.  This
will induce a strong low level jet of 55 to 65 knots will result in
showers becoming more numerous across the region Monday night. Still
will have to keep an eye on remnant low level cold air/pockets of
freezing rain Monday evening particularly the Lower CT River Valley.
While other guidance warms things quicker, the high resolution 4 km
NAM/NMM models are depicting below freezing temps persisting beyond
00z so something will have to watch closely.

No matter what happens across the interior during part of the
evening, the low level jet/track of surface low pressure will win
out and yield rising temps.  Continued forcing should allow for
periods of rain showers.  The interior should see temps rise into
the 40s and and into the 50s along the coastal plain. This may
lessen the inversion and perhaps allow for a period of 35 to 45 mph
wind gusts along and southeast of a Boston to Providence line. Will
have to monitor the potential for a wind advisory in this region.
CIPS analogs and EPS ensembles are showing decent probs of 35+ knot
wind gusts across eastern New England towards 12z Tuesday.

Tuesday...

A very mild start Tuesday with readings well up into the 40s to the
middle 50s.  Some lingering showers possible especially near the
south coast ahead of the approaching cold front.  Should be dry by
afternoon, but cold advection behind the front will result in
falling temperatures.  It will also be windy as well with westerly
wind gusts of 30 to 45 mph and we may be near wind advisory
criteria in a few locations Tue morning.

Tuesday night and Wednesday...

Dry and seasonably cold weather returns behind the cold front
Tuesday night and Wednesday.  High temps on Wednesday will mainly be
in the 30s with a ridge of high pressure in control.

Thursday and Thursday evening...

Another low pressure system will be tracking well to our northwest
into Quebec.  At the same time a shortwave dropping into the Ohio
Valley will result in a secondary intensifying coastal low pressure
system.  The biggest uncertainty is how quickly and how far
southwest this secondary system develops.  The ECMWF continues to
develop it quicker and farther southwest than the GFS/GGEM models.
However, there are some GEFS ensemble members that support the
ECMWF.  So in a nutshell, if the system intensifies quicker/further
southwest a more significant precipitation event would occur.  A
slower developing system would result in a short-lived lighter
precipitation event.

Ptype remains uncertain as well, but the higher risk for snow and
ice exists across the interior.  A coastal storm that intensifies
quicker and further southwest would bring more snow/ice to portions
of the interior, where a slower developing low will allow for a
warmer/wetter solution.  On the coastal plain, either solution will
probably be a challenge to get significant snow at this point given
upper level configuration.  Nonetheless, some snow would be possible
at the onset if the colder/stronger solution verifies.

Friday and Saturday...

Mainly dry and seasonably cold weather expected as another ridge of
high pressure builds into the region form the west.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
Forecaster Confidence Levels...

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Short Term /through Monday/...

This afternoon and tonight...High confidence. VFR. NW winds
gusting to 20-30 kt, diminishing early this evening.

Mon...Moderate confidence.
VFR most of the day, although some light rain, and even light
freezing rain across NW MA may coincide with some MVFR dipping to
IFR conditions by late afternoon and the evening hours.

KBOS TAF...High confidence in TAF.

KBDL TAF...High confidence in TAF.

Outlook /Monday Night through Thursday/...

Monday night...Moderate confidence.  MVFR-IFR conditions expected in
periods of showers.  Any lingering freezing rain across the interior
should change to plain rain by mid to late evening.  Strong low
level jet will result in LLWS along with southwest wind gusts of 30
to 40 knots developing on the coastal plain especially toward
daybreak.

Tuesday...Moderate confidence.  Left over MVFR/IFR conditions in
some showers should improve to mainly VFR by afternoon.  Westerly
wind gusts of 25 to 35 knots expected with a few gusts up to 40
knots possible through early afternoon.

Tuesday night and Wednesday...High confidence in mainly VFR
conditions.

Thursday...Low to moderate confidence.  MVFR-IFR conditions possible
in a wintry mix/rain but timing/duration remain uncertain.

&&

.MARINE...
Forecaster Confidence Levels.

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Short Term /through Monday/...High Confidence.

NW winds will continue to gust to 25-30+ kt through the afternoon
with seas remaining 5-7 ft through evening over the outermost
waters...but only 2 to 4 ft in the sounds. Small craft advisories
continue.

Late tonight into early tomorrow, high pressure will yield quieter
boating weather until stronger SW flow develops tomorrow evening,
at which point another round of small crafts or even gales are
possible.

Outlook /Monday Night through Thursday/...

Monday night-Tuesday...Moderate to high confidence. Southwest wind
gusts of 30 to 40 knots develop Monday night as a result of a
developing strong low level jet and shift to the west at the same
speeds Tue behind the cold front. Inversion will be a limiting
factor, but expect will need Gale Headlines.  Seas should build to
between 7 and 12 feet across the outer-waters with the highest
of those in our southern waters, where fetch will be longest.

Tuesday night and Wednesday...Moderate to high confidence. Northwest
small craft wind gusts of 20 to 30 knots expected in the cold
advection pattern.

Thursday...Low confidence.  Winds speeds/direction and wave heights
are highly uncertain and will depend on how quickly and where
secondary coastal low pressure develops.
