Area Forecast Discussion
National Weather Service Taunton MA
231 AM EST Tue Jan 31 2017

.SYNOPSIS...
Low pressure will bring a widespread accumulating snowfall to the
region this afternoon into early Wednesday. The remainder of the
week will trend colder with blustery conditions at times. Another
shot of snow is possible sometime late Sunday into Monday.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
1030 PM Update...

Last of snow showers passing near or just S of KMVY-KACK have
exited as the low scooted offshore this evening. Decent pressure
gradient remains in place across E Mass at 03Z, with NW winds
gusting to 22 kt at KACK and 26 kt at KPVC. W-NW winds continue to
stir further W as well, though appear to be diminishing across the
lower CT valley into interior SW CT and along the S coast of
RI/CT.

Latest surface map showing high pres ridge building E out of
central and E NY state, and should shift E overnight allowing
winds to diminish as they start to back to W-SW during the early
morning hours. With the lower winds and mainly clear skies, should
see radiational cooling kick in with dewpts ranging from 5 to 10
degrees across areas away from the immediate coast.

Have updated near term forecast to bring conditions current and
incorporated trends into the remainder of the overnight forecast.

Previous Discussion...

Will see W winds increase with significant gusts over the coastal
areas and across the waters into the early morning hours on
Tuesday. The mid-level ridge building in from the W tampering the
winds with time, likely to see with the present clearing
conditions pockets of radiational cooling within the CT River
Valley and also nestled in the valleys within the Worcester Hills.
Going to be some cold spots. Most areas with lows in the teens but
single digits for the N/W interior of MA and CT (including the
Tolland Hills). All depends as to whether winds become light.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM WEDNESDAY/...
Tuesday into Tuesday Night...

 * Widespread Accumulating Snowfall is Expected across the area
   Tuesday Afternoon into early Wednesday.

 * Main takeaway...Impacts to the afternoon into evening commute.
   Hazardous travel conditions. Give yourself extra time. Simply
   plan accordingly.

Tricky forecast is on track as a bump in the pattern N or S could
either enhance or limit the snowfall amounts for S New England.

Low pressure over the N Plains will dive into S New England Tuesday
pushing the mid-level ridge offshore. Anticipate a dry morning before
precip begins to spread from SW to NE. Both the GFS/NAM and Hi-res
Guidance are indicating that at the onset there will be good QG-
forcing with isentropic lift and frontogenesis around 20z-02z. The
models also show good omega in the snow growth region as well as
steep lapse rates which could indicate a quick burst of snow
around the evening commute. This potential banding appears to set-
up across CT/RI and into MA close to the Pike. However the models
could shift this area north or south so played conservative for
now with the location. Snow will continue through the evening as
surface low slowly moves eastward creating an inverted trough set-
up as another surface low develops across upstate NY.

Hi-res guidance is outputting a decent amount of QPF during the
overnight hours across E MA within the inverted trough setup.
Still hard to nail down which area could see this heavier amount
of snow, but right now confidence is across Plymouth county and
down on the Cape. However, the synoptic guidance is keeping the
inverted trough set-up a bit further N closer to Essex county.
These are quite tricky to forecast so for now will continue to
mention the potential for 5 to 6 inches of snow along the eastern
MA coastline.

Overall this event has several waves of low pressure which will
impact the region. When this system is through, appears that we
could see between 2-4 inches of snow across the region, with some
areas seeing a bit more if they fall under the right mesoscale
bands. Still do not want to rule out the potential for 6 inches
across the E MA coast due to the inverted trough. This will be a
fluffy snow as the cold arctic area over the region will result in
high snow ratios.

Winter weather advisory has been issued as snow accumulations will
generally be 3 inches across the area and the impact to the evening
commute. Still a lot of wiggle-room with the models when it comes
to these mesoscale set-ups so will let the midnight crew fine tuned
the advisory with the 00z models tonight, especially if it needs to
be shifted southward.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...

Highlights...

* Trending colder with below normal temps and blustery at times Thu
  into Sat
* Chance of snow sometime Sun-Mon but confidence is low

Overview...

Pattern in the extended features an anomalous mid level ridge over
Alaska with polar vortex over Hudson Bay drifting east across
Canada. Broad longwave trof from the Gt Lakes to New Eng will result
in mainly dry and cold conditions into the weekend with below normal
temps, coldest Fri-Sat period. Low amplitude Pacific shortwave then
approaches for late in the weekend. With lack of downstream
blocking, pattern remains progressive and not very amplified which
would downplay a potential significant storm Sun-Mon period but this
is still Day 6 so there remains inherent uncertainty.

Wednesday night through Saturday...

SNE will be under influence of broad longwave trof with cyclonic NW
flow. Moisture is limited so outside of a few flurries/snow showers
from time to time, looking at mostly dry conditions during this
period. Trending colder into the weekend as 850 mb temps fall to
-14 to -18C Fri/Sat resulting in below normal temps.

Sunday into Monday...

Still considerable uncertainty regarding a potential storm as there
is lots of spread among the deterministic and ensemble guidance. As
previous forecaster indicated, low confidence at this range and
associated energy is out in the middle of the Pacific. Both GEFS and
EPS probs of 0.50" QPF are quite low, less than 10 percent, which
would argue against a significant storm unless the shortwave can
amplify further.

&&

.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
Forecaster Confidence Levels...

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

0330Z update...

Overnight...High confidence.
VFR. W winds gusting to 20-25 kt across the E coast through 06Z-
08Z, then diminishing.

Tuesday and Tuesday night...Moderate confidence in trends...lower
confidence on timing.
VFR through Tuesday morning. However, expect -SN to overspread
the region from SW to NE Tuesday afternoon into the early evening.
-SN should continue Tuesday night and there may be localized bands
of SN/+SN. Conditions will trend to MVFR-IFR levels with localized
LIFR conditions possible at times. Untreated runways will likely
become snow covered.

KBOS TAF...Will usher -SN into the terminal during the PM push.
Lower conditions as we go into the evening hours with the greater
chance of SN/+SN. We'll improve going into Wednesday morning. A
general 2 to 4 inches of snow accumulation is forecast, but locally
higher amounts are possible up to 6 inches. The area of risk includes
the terminal.

KBDL TAF...Lower confidence for SN/+SN impacts, a general -SN is
in the forecast. Will need to monitor closely. Takeaway is we'll
see impacts to the PM push. A general 2 to 3 inch snow accumulation
is forecast.

Outlook /Wednesday Night through Saturday/...Moderate confidence.

Mostly VFR cigs with areas of MVFR at times. Gusty NW winds to 25 kt
at times.

&&

.MARINE...
Forecaster Confidence Levels...

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