Area Forecast Discussion
National Weather Service Taunton MA
437 AM EST Sun Feb 12 2017
.SYNOPSIS...
Spotty light snow early this morning becomes a widespread
steady snow this afternoon and heavy at times into early this
evening. Snow may mix with or change to sleet and rain across RI
and southeast MA. This is in response to rapidly intensifying
low pressure off the coast of RI and MA which will bring
significant snows and a possible wintry mix tonight into Monday.
This intense low will bring a threat of damaging winds Monday
especially to Cape Cod. High pressure and cold conditions prevail
for Tuesday. Another storm system is possible Wednesday into
Thursday. A renewed period of cold weather is forecast Friday
into the weekend, however there is a moderating warmer trend
into next week.

.NEAR TERM /THROUGH MONDAY/...
430 AM update...
*** Snow heavy at times this afternoon & early evening followed by
strong to damaging winds Mon along with potentially more snow ***
Overview...
Models in good agreement on the overall evolution of developing
winter storm and especially snowfall potential on the front end
today but then some uncertainty on how quickly and close storm
intensifies to the region. This greatly impacts magnitude of strong
winds Mon along with comma-head snows. Good agreement on low pres
intensifying tonight as it tracks from south of Long Island to near
Nantucket at 06z to somewhere east of Cape Cod over western Georges
Bank. Models struggling on how far southeast mid level low
digs/tracks. This will impact the exact trajectory of the storm's
potent comma-head and associated heavy snow. In addition, the exact
track, speed and amplification of the mid level circulation will
also determine how quickly the surface low gets captured and briefly
pulled back toward the eastern MA coastline. This directly impacts
the pres gradient and associated wind field/damaging wind threat.
GFS is most robust with entire system farther to the southwest than
remainder of the guidance. ECMWF is in the middle of the pack. Both
the EC and GFS have a sub 970 low over western Georges Bank Mon!
Unfortunately southern New England is on the back edge of this
potent developing cyclone. Thus a small shift in storm track will
have a huge impact on our forecast. Overall looking at a three part
storm with snow heavy at times this afternoon then a bit of a lull
tonight as dry slot overspreads the region, especially CT/RI and
southeast MA, followed by comma-head snows Monday and strong to
damaging winds.
Timing...
Spotty light snow this morning then good agreement on a steady
warm advection snow overspreading the region 9 am - 12 pm, then
becoming heavy at times this afternoon as good forcing for
ascent enters the snow growth region. Snowfall rates of 1-2" per
hour are possible this afternoon. Warmer air begins to advect
northward and will likely result in snow mixing with or changing
to sleet and rain across RI and southeast MA. Thus highest
totals will be across northern CT into northern MA. As for the
city of Boston, always a tricky forecast with marginal temps and
onshore flow. However temps are fairly cold aloft and even by
00z tonight it's about -4C at 850 over Boston. This combined
with low pressure intensifying south of Long Island should
result in pressure falls turning the wind in Boston to NNE. Thus
leaning toward mostly all snow for much of the day.
Then tonight dry slot moves across the region and dries out the snow
growth region, especially across CT/RI and southeast MA. Thus precip
will likely transition to drizzle or low top showers. However
interior CT/RI and southeast MA where temps will be at or below
freezing could see a period of freezing drizzle/rain. North of the
MA pike mid level dry air not as deep, which should support snow to
continue and pile up.
Then beginning around daybreak Monday the surface low undergoes
significant amplification in response to tremendous height falls.
This results in a rapid developing comma-head into eastern MA and
possibly westward into the Worcester Hills, eastern CT into RI. Thus
the column becomes saturated again along with falling temps
promoting another round of snow...possibly thundersnow given
crashing heights/steepening mid level lapse rates. Beneath this
comma-head a period of heavy snow is possible (greatest risk eastern
and northeast MA) along with very strong to damaging winds resulting
in near blizzard conditions possible.
Snowfall amounts...
Highest snow totals 12-18” amounts look to generally remain along
and north of the MA turnpike. Possibly a tad lower in the city of
Boston given potential mixing but at least 8-12" expected there.
South of the MA pike into northern portions of CT/RI to the southern
suburbs of Boston 6-12" remains likely. Then amounts taper downward
to the south coast given snow changing to sleet and rain later
today.
Winds....
Strongest winds will occur early Mon morning and continue
through much of the daylight hours on Mon. Sustained winds of
20-30 mph with gusts to 40 mph are likely across most of the
region. The only caveat will be areas along the E and SE
coastlines, where 30-40 mph sustained winds will combine with
occasional gusts 60+ mph early Monday morning and continuing into
the daylight hours. Greatest risk for damaging winds will be from
Cape Ann to Cape Cod and Nantucket. The blizzard Watch accounts for
very strong winds. A second area of strong winds will be along the
south coast. This area will be covered by a high wind watch given
blizzard watches are not posted here.
Headlines...
NO changes to headlines from previous forecast. Did not have enough
forecast confidence to upgrade the blizzard watch to a blizzard
warning given model spread in position/track and intensity of comma-
head and surface low. However within the blizzard watch confidence
is highest over coastal Essex county for blizzard conditions to be
observed.
Uncertainty...
The greatest uncertainty in the forecast is how far inland does
potent comma-head track and its duration. This will determine if
blizzard conditions especially snowfall intensity are met Mon
morning and afternoon across eastern MA. Given this uncertainty did
not upgrade blizzard watches to blizzard warnings.
Conversely do have increased forecast confidence on damaging winds
across Cape Cod and possibly Cape Ann with gusts 50+ kt Monday
morning and afternoon. Moderate to high probability for at least
isolated power outages across this area.
As always, stay tuned to updates as forecast snowfall/sleet
amounts as well as winds may be adjusted as we approach the
onset of the storm.

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
*/ Highlights...
- Winter continues to prevail into early next week
- Monitoring the possibility of a late-week storm system
- Perhaps a significant warm-up into late February?
*/ Overview...
Big meltdown into late February? Above average temperature forecasts
per CPC for the 8-14 day and 3-4 week period. This coinciding with
quieting teleconnections as the stratospheric polar low shifts from
N Canada into N Asia with the better component of cross-polar flow
into W Europe. A weakening albeit shifting pattern to the E, quite a
surprise to see ensemble means are 8-12 days out forecasting a +2SD
H5 ridge pattern and a +20C H85 temperature anomaly for the February
20th to 22nd timeframe. Closely watch this going into late February.
But prior to will continue to see a favorable environment towards
cyclogenesis across the NE CONUS. A psuedo rex block over the NE
Atlantic acting to amplify and slow the upstream pattern, this as
the phase 7 to 8 of the MJO invoking stronger high pressure over the
ITCZ S of a dominant H5 Aleutian low acts to enhance the W to E
Pacific jet thereby amplifying the +PNA over the Inter-Mountain W
and subsequently lead to favorable troughing downstream.
Need to closely watch energy over the SW CONUS and its possible sub-
tropical connection to the phase 7 to phase 8 of the MJO. In such a
change of phase it has been noted there is a shift of stronger storm-
type development transitioning from Miller A to Miller B, that is
more preference of S-stream energy undergoing surface cyclogenesis
rather than N-stream energy in vicinity of the NE CONUS. Grasping at
the connection which is not entirely clear though the correlation is
there per recent research.
Will keep the discussion short and brief below, focusing on targets
of opportunity, particularly the storm for the late week period.
*/ Discussion...
Monday night through Tuesday...
Winter weather persists. Strong NW flow initially, weakening with
time. Mainly an isallobaric-gradient response, NW wind gusts 45-55
mph across the E-coast of MA, particularly Outer Cape and Nantucket.
Winds quickly diminish into Tuesday morn as a ridge of high pressure
builds into the region. Cold air advection having concluded, begin
to see the airmass moderate with H925 temperatures warming up around
-6 to -8C. Still a chilly day, also given a deep snow pack for some
locations, though winds will be light. Lows overnight in the teens
with wind chills roughly 5 to 10 degrees lower, highs around the low
30s with the mid-February sun angle, scattered stratocumulus.
Tuesday night through Thursday...
Continued uncertainty. Considerable spread in both deterministic and
ensemble solutions. Perhaps a double-barrel low setup? Unclear as to
whether N-stream polar-origin energy, rather moisture deprived, is
fueled by S-stream energy out of the SW CONUS, whether the two come
together and phase, or at the minimum interact. Some solutions hint
at rapid cyclogenesis across the Gulf of Maine with trowaling / snow-
banding across the backside of the system into E New England. Others
have a sweeping cold front of light snow that pushes S-stream energy
out to sea yielding a minimal impact for the region. Too early to
say and maybe that is perhaps that we do not have good sampling of N-
stream energy as it reside far N across the Arctic circle where info
from satellites could be a bit more cumbersome. Will continue to
monitor, but in the meantime hold with an ensemble mean forecast.
Some early forecast notes, leaning with a light snowfall event with
higher amounts, perhaps advisory level, roughly 2 to 4 inches, over
N/NE areas of MA. Be some precipitation-type issues along the coast
with rain mixing in. Just an early guess with low confidence for now.
Thursday night and beyond...
Cold weather prevails. Behind the late week system and along the NE
periphery of the building ridge across the Central CONUS, NW flow
prevails that limits the SW approach of warmer air. High pressure
and drier weather with what would appear to be a more seasonable
to slightly above-seasonable temperature trend.

.AVIATION /10Z SUNDAY THROUGH THURSDAY/...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
06z update...
Thru 15z...higher confidence on cigs/vsbys but lower on ptype
MVFR-IFR conditions over eastern MA slowly advance westward into
RI/CT and western-central MA thru the early morning hours. Some
light spotty snow will accompany the low clouds. Can't rule out
spotty light freezing rain/drizzle however thinking light snow
will be more common. Gusty NNW winds will persist over Cape Cod
and the Islands.
After 15z...moderate to high forecast confidence.
MVFR-IFR will lower to IFR-LIFR as snow overspreads the entire
region between 15z-18z then increases intensity 18z-21z with
moderate to heavy snow at times. Snowfall rates of 1-2" per hour
is possible. Rain-Snow line will come onshore to the south coast
18z-21z and then deeper into RI and southeast MA 21z-24z.
Tonight...moderate to high forecast confidence.
IFR-LIFR in a wintry mix of precip across CT/RI and southeast
MA, possibly including freezing drizzle across interior CT to
the MA pike. North of the MA pike precip likely remains all
snow. Then toward 09z-12z Mon NNW winds will increase
dramatically with gusts over 50kt possible eastern MA especially
Cape Ann to Cape Cod to Nantucket. In addition any mixed precip
will flip back to snow 09z-12z with a period of heavy snow
possible northeast MA.
Monday...
IFR-LIFR early gradually improves to MVFR however very strong to
damaging NNW winds 50+ kt possible Cape Ann to Cape Cod to
Nantucket 12z- 18z. This is also the same here that could have a
period of moderate to heavy snow 12z-18z from Cape Ann to Cape
Cod. Hence near blizzard conditions. Conditions slowly improve
during the afternoon from west to east.
KBOS TAF...Moderate confidence in TAF. Main uncertainty is ptype
this morning. Should be mainly light spotty snow but at times
could be light freezing drizzle. Steady snow arrives 15z-18z and
the heavy at times 18z-02z with hourly snowfall rates of 1-2" at
times. Could mix with rain at times 22z- 02z but thinking
mainly snow.
KBDL TAF...Moderate forecast confidence. Some uncertainty on
ptype this morning, spotty light snow or spotty light freezing
rain. Thinking mainly spotty light snow but can/t rule out
spotty light freezing drizzle at times. Steady snow develops
12z-15z then steady after 15z and heavy at times. Snow may mix
with sleet 18z-00z and then freezing drizzle/rain possible
tonight, flipping back to snow toward Mon morning.
Outlook /Monday Night through Thursday/...Moderate Confidence.
Tuesday...
VFR. Breezy NW winds diminishing. Perhaps some SCT low-end VFR cigs.
Wednesday into Thursday...
Potential -SN with IFR-LIFR impacts. Mixing with -RA for the S/SE
coastal terminals. Light winds during the event turning out of the
NW and becoming blustery as -SN concludes.
Friday...
VFR. Breezy NW winds diminishing. Perhaps some SCT low-end VFR cigs.

.MARINE...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
*** Powerful/dangerous Coastal Storm impacts the waters Monday ***
Today...
NNE winds with a steady snow overspreading the waters this afternoon
then changing to rain southern waters. Vsby lowering to 1-3 miles.
Tonight...
Low pres tracks from south of Long Island to Nantucket to east of
Cape Cod. By 12z Mon a sub 980 mb low expected east of Cape Cod!
Gale force winds tonight approach storm force by morning. Rain and
snow limit vsby.
Monday...
Powerful/dangerous sub 970 mb low over Georges Bank! NNW winds 50+
kt likely along with rapidly building seas. Snow heavy at times
lowering vsby. Strongest wind and largest seas over eastern MA
waters.
Outlook /Monday Night through Thursday/...Moderate Confidence.
Tuesday...
Blustery NW winds diminishing with time. Storm to gale force Monday
night. Forecast below 25 kts into Tuesday morning. Seas undergo a
period of subsiding initially 20-25 feet on the outer waters Monday
evening to below 5 feet by Wednesday morning. The threat of freezing
spray diminishing throughout.
Wednesday into Thursday...
Potential rain / snow event for the waters. Light winds during the
event as a storm system deepens over the Gulf of Maine. Lots of
uncertainty concerning where the low deepens and the magnitude at
which it deepens. Anticipating winds to enhance, especially as the
storm exits with blustery conditions out of the NW. Would expect
seas to amplify.
&&
.TIDES/COASTAL FLOODING...
Increasing easterly flow will likely produce a surge of 1 to 1.5
feet along the Massachusetts east coast from Boston to Plymouth.
This will likely cause pockets of minor coastal flooding. The rest
of the discussion pertains to the Monday early afternoon high tide.
For the Monday early afternoon high tide, we are anticipating the
potential for minor to moderate coastal flooding from Salisbury to
Plymouth and the Nantucket Harbor area. And from Sandwich to
Eastham, there is a potential for moderate coastal flooding with
even a risk of pockets in the moderate to major coastal flooding
range around the time of the early Monday afternoon high tide. Will
break our reasoning and potential impacts by location below:
Salisbury to Plymouth...Minor to moderate coastal flooding
possible with greatest impact along the exposed ocean shorelines
such as Hull...Scituate...Marshfield, and Duxbury. Although the
wind direction is expected to be NNW, waves of 15 to 20 feet
just offshore may compensate for a partial offshore component of
the wind. Some wave overwash is possible along the exposed
shoreline, and significant erosion may occur Salisbury to
Rockport, including Plum Island, as well as Hull to Plymouth.
Sandwich to Eastham...Moderate to major coastal flooding is
possible due a combination of a potential surge around 3 feet
and waves around or even slightly higher than 15 feet in Cape
Cod Bay. Erosion along this stretch of coastline may be severe
and some low spots may have 3 or more feet of inundation. A few
of the most vulnerable homes and other structures could be
damaged by wave action along this stretch of coastline. What is
significant for this stretch of coastline is that a NNW wind
with gusts over 60 mph leading up to the high tide will be
aligned with a significant fetch coming right up to the
shoreline. Although still a couple of days away, this could
become a dangerous situation for this particular stretch of
coastline.
Ocean side of Cape Cod and the East Side of Nantucket...The issue
for these areas will likely be the potential for severe erosion from
waves of 20 to 25 feet approaching the shoreline.
Nantucket Harbor area...A surge of 2 feet held in by a NNW wind
potentially gusting over 60 mph may cause moderate coastal flooding
with low areas possibly experiencing 1 to 3 feet of inundation.
Guidance...As is typically the case, we have gone above both wave
and storm surge deterministic guidance with the SWANNAM and ETSS
being the best starters but still probably a little too low.
Experimental wave run up guidance is showing a risk of erosion and
some overwash at the Hull and Scituate hot spots for the early
Monday afternoon high tide. Finally, we appreciate special support
from the National Hurricane Center on experimental surge and
inundation guidance, which appear to validate our current
thinking.
