Area Forecast Discussion
National Weather Service Taunton MA
1233 AM EST Sat Mar 4 2017

.SYNOPSIS...
An arctic cold front will cross the region this evening which will
be accompanied by scattered snow showers along with a few heavier
but localized snow squalls. Behind the arctic front near record cold
and bitterly cold wind chills tonight into Sunday morning.
A significant warming trend follows early next week with
temperatures likely back into the 50s Tuesday and Wednesday,
along with a chance of showers. Colder weather returns late in
the week with a few snow showers possible Thursday night into
early Friday.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
***Localized brief heavy snow squalls continue this evening***

10pm update...
Noting the gradual development of a modest narrow inverted trof.
This is especially noticeable in local meso-obs/winds suggest
some decent convergence colocated with a narrow min in MSAS
pres. This continues to provide enough of a focus for continued
SHSN which as the trof pulls both E and S will move across
portions of E MA and RI through about 1AM. SN accums should
remain light, generally under an inch but quick accums on area
roadways cannot be ruled out as these move through.

Otherwise, forecast on track. POPs/WX are close to both
operational HRRR and experimental HRRR which are now carrying
this inverted trof well.

Previous discussion...

After analyzing all of the 12z guidance including the 12z
GFS/NAM/NAM nest/NAM nest parallel/19z HRRR & HRRRX/12zARW/NMMB/BTV-
WRF and latest RAP, good model consensus on two bands of snow
showers/squalls impacting southern New England this evening and
overnight. Hi Res models simulating very well two lines of snow
squalls currently over eastern PA and NY state. In fact noting VCTS
with these squalls earlier at ELM NY. This activity enters western
MA/CT including the Greater Hartford/Springfield area between 5 pm
and 7 pm, then eastward into RI and eastern MA including Boston 7 pm
to 9 pm and shortly thereafter across Cape Cod. Some of the guid
weakens this initial band of snow showers/squalls as it traverses
eastward especially into RI and eastern MA.

As the lead arctic short wave approaches from the west it induces a
surface wave on the arctic front over southeast NH 22z-02z with an
inverted trough extending westward into southern VT. As this
boundary and associated low level convergence slips south a new line
of squalls will likely move into northern and eastern MA including
Boston between 10 pm to 1 am. Pretty impressive how well these Hi
Res models are simulating the squalls over eastern PA and NY then
model consensus over southern New England this evening. Thus we have
above average confidence on the timing and areal coverage
(scattered) of snow showers/squalls across the entire region this
evening.

As is the case with warm season convection some towns will be
impacted while neighboring communities will be spared. While a
lot of snow is not expected, some of the more intense squalls
will result in the potential for a quick 0.5 to 1.0 inch in 15-20
mins, covering roads quickly with a light accumulation and vsby
briefly but rapidly lowering to a 1/4 mile or less. Seeing many
social media posts upstream across PA/NY of many accidents as roads
quickly become slick along with poor vsby. In addition gusty WNW
winds will accompany the squalls. Will continue to communicate these
details via our Special Weather Statement.

Then behind this arctic front very strong CAA overspreads the area
with 850 temps lowering to about -22C by 12z Sat. This will result
in temps plummeting into the teens with single digits well inland.
These frigid temps combined with gusty NW winds up to 35 mph will
result in bitterly cold wind chills from minus 5 to 5 above zero.
Across the higher terrain of the Worcester Hills to the east slopes
of the Berkshires -5 to -15 wind chills will be common.

Given the magnitude of the cold air tonight's temps were derived
from the coldest guid sources.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
Saturday...

Second surge of arctic air comes tomorrow from trailing arctic short
wave in the afternoon. Good forcing for ascent with this feature
however models are indicating a lack of low and mid level moisture
for short wave to work with. Thus models are not generating much qpf
given the lack of moisture despite steep lapse rates and strong
forcing. Will have to watch how this evolves as sometimes these
potential short waves finds a way to pool enough moisture for
scattered snow showers/squalls to materialize. For now will keep the
forecast dry but later shifts will need to reevaluate.

Behind this short wave a second surge of arctic air advects across
the region with 850 temps lowering to -22C along the south coast to -
24C along the NH/MA border. Will be interesting to see how cold the
850 temp is on the 00z observed CHH sounding Sat evening, as the
coldest 850 temp observed in the month of March is -23C (per SPC
sounding climo)! Puts into context how cold of an airmass we are
dealing with.

Sat night...

Coldest temps will be observed tomorrow night as the core of the
cold air settles over the region. Mins will range from near zero
northwest MA to the teens along the south coast with single digits
across most of the area. Mins were derived from the coldest data
sets. Given robust CAA continues especially during the evening gusty
NNW winds will yield wind chills from zero to about minus 10 with
minus 15 to minus 20 across the high terrain. Will highlight these
bitterly cold wind chills via our Special Weather Statement but may
eventually need a wind chill advisory.

Dry weather prevails but could see some ocean effect snow showers
esp in the evening across the outer Cape as winds back to about 330
degs.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Highlights...

* Significantly milder Tue/Wed with some showers.
* Turning colder Thu night with a few snow showers possible

Details...

Sunday...

Wind chills may still be near Advisory criteria of -15 degrees in
far northwest MA early Sunday morning with 0 to -10 degrees
across all of the rest of MA, except the southeast. However, the
core of the cold air mass will be shifting offshore, which will
allow some relief from the bitter cold. High pressure overhead
coupled with the increasing March sun angle should allow highs
to recover into the 30 to 35 degree range. Those temps are still
nearly 10 degrees below normal for early March. Northwest winds
will be gusty in the east, but will be diminishing during the
day.

Sunday night and Monday...

High pressure crests over the region Sunday night...so despite
rising height fields expect a good night of radiational
cooling. Low temps should bottom out well down into the teens
across many locations. with even a few single digits expected in
northwest MA and some of the normally colder areas in southeast
MA.

A return southerly flow of air should occur Monday as high pressure
moves off the coast. This should allow high temps to recover to
the mid and upper 40s Monday afternoon in many locations. The
exception might be along the immediate coast, where sea breezes
may result in high temps struggling to break 40. Skies will
start out sunny but there will be an increase in high cloudiness
from west to east during the afternoon.

Monday night through Tuesday night...

Strong low pressure in western Ontario will be slowly heading toward
Hudson Bay as high pressure shifts farther east off the coast.
The result will be a southerly flow of much milder air into
southern New England. Best forcing will be located well to our
northwest, but warm advection should create a chance of light
showers Monday night, which could possibly start as some snow or
freezing rain near the VT/NH border.

Skies will be mostly cloudy and there is a chance of showers Tuesday,
but temperatures will climb to the lower and middle 50s. Expecting
a weak cold front to move across the region Tuesday night,
enhancing the chances of showers.

Wednesday...

There is a slight chance of an early morning shower. Then, with
increasing sunshine and westerly downsloping winds, temperatures
are forecast to climb to 55 to 60.

Thursday...

A secondary cold front is forecast to move through on Thursday.
Timing is slightly different amongst models. Highs mainly in
the 40s. By Thursday night, a brisk and somewhat unstable flow
of air will usher much colder air into the region. There is a
chance of a few snow showers. Preferred the cooler guidance, in
deference to the much colder ECMWF solution. Lows Thursday night
mainly in the 20s, except teens northwest MA and near 30 outer
Cape Cod and Islands.

Friday...

Weak high pressure will lead to a partly sunny day with highs
in the lower to mid 40s. Attention will then turn to an
approaching warm front. There is a big discrepancy in the models
for next weekend's weather, which is highly dependent on the
timing and location of this warm front. But that is currently
beyond our forecast period.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
Forecaster Confidence Levels...

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

Through 12Z...High confidence.
Mixed IFR/MVFR conditions continue for SE MA terminals through
08Z. VFR follows for all TAF sites. Winds increase with NW gusts
20-30 kt.

Today...High confidence.
Mainly VFR conditions but low probability of additional snow
showers (mainly VFR but a few brief periods of MVFR possible)
during the late morning hours. NW winds continue 25-35 kt again.

Tonight and Tomorrow...High confidence.
VFR but MVFR-IFR possible across the outer Cape as ocean effect
clouds and snow showers may move into that region. Gusty NNW
winds 20-30 kt tonight diminish somewhat on Sun.

KBOS TAF...High confidence in TAF.

KBDL TAF...High confidence in TAF.

Outlook /Sunday Night through Wednesday/...

Sunday night and Monday...High confidence. VFR.

Monday night into early Wednesday...Moderate confidence.
VFR but areas of MVFR-IFR conditions in lower clouds and
scattered showers from time to time. Greatest risk for IFR and
heavier showers is Tuesday night.

Mid-morning through Wednesday afternoon... High confidence.
Becoming VFR through the region. Gusty west winds to 15-25 kts.

&&

.MARINE...
Forecaster Confidence Levels...

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

*** NNW Gales, Moderate Freezing Spray & possible Arctic Sea
    Smoke ***

4 pm update...

Short Term /through Sunday/...

Tonight...High confidence.

First surge of gales overspread the waters roughly 8 pm to 2 am from
northwest to southeast behind first arctic front. The front will
likely be accompanied by brief but intense snow squalls lowering
vsby to 1/4 mile or less at times. Improvement 2nd half of the
night. However arctic air will result in areas of moderate freezing
spray across the eastern MA waters.

Saturday...high confidence.

Second arctic front crosses the region during the afternoon with
another surge of NNW gales. Moderate freezing spray eastern MA
waters along with possible snow squalls esp offshore.

Sat night...high confidence.

NNW gales continue with core of arctic air over the MA/RI waters.
Widespread moderate freezing including the RI waters. Thus freezing
spray advisories have been expanded. Low risk for a few hours of
heavy freezing spray eastern MA waters. Given how cold and dry this
airmass will be could see shallow arctic sea smoke develop.

Outlook /Sunday Night through Wednesday/...

Sunday...High confidence.  Freezing spray concerns should come to an
end by Sunday afternoon as the air mass modifies. Wind gusts
will also gradually diminish as high pressure slowly builds in
from the west...but still expecting small craft advisory
criteria wind gusts until mid-afternoon.

Monday and Monday night...High confidence. Winds and seas
should below small craft thresholds.

Tuesday...Marginal southerly small craft wind gusts...to near
25 kts...may develop by Tue afternoon as high pressure
continues to move east allowing for southerly gradient to
increase. 5 to 6 foot seas may develop across our southern
waters. Scattered showers.

Tuesday night and Wednesday...5 to 7 ft seas over the southern
and far eastern outer waters. West to west-southwest winds will
gust to 20-25 kt at times. Scattered showers Tuesday night and
early Wednesday morning could reduce visibilities to 3 miles or
less.
