Area Forecast Discussion
National Weather Service Taunton MA
954 PM EST Sun Jan 14 2018

.SYNOPSIS...
Canadian high pressure will bring very cold weather into Monday with
some ocean effect snow across eastern MA late tonight into
Monday evening. Low pressure drives east from the Great Lakes
Tuesday, then redevelops off the Mid Atlantic coast. This will
bring snow later Tuesday and Wednesday. Colder air follows for
Wednesday night and Thursday. Atlantic high pressure then builds
into New England with dry weather and milder temperatures by
next weekend.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...

950 pm update...

1048 mb high pressure system will continue to shift eastward
across Quebec. The result will be winds shifting from the
north to the northeast. The result will be an increase in low
clouds across eastern MA and RI overnight. As the previous
forecaster mentioned...still some timing differences as to when
the ocean effect snow showers develop along the eastern MA
coast. Probably should see some light snow showers/flurries
develop after midnight across portions of eastern MA. Most of
the activity through daybreak with little more than a coating
of snow in most locales. However...may see a narrow band of
steadier snow develop just south of Boston after 4 or 5 am with
some impact to the am rush hour possible.

Otherwise...inland from the Boston to Providence corridor skies
will be mostly clear overnight. Temperatures should have no
problem falling into single numbers across much of area, with
a few readings below zero in the normally coolest outlying
locations. Milder upper teens to lower 20s expected along
portions of the immediate MA coastline as well as Cape Cod and
Islands with NE flow developing along with low clouds.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
* Ocean Enhanced Snow Near E MA Coast
* Winter Weather Advisory South of Boston

PLEASE NOTE: Because of the possibility of a more widespread
snowfall Tue into Wed (See Long Term below), our snowfall maps
on the web (including probabilities) will focus on that since
it potentially will affect more of SNE. We will post the
expected snowfall map for late tonight into Monday evening on
social media.

Confidence is increasing on receiving accumulating snow near E
MA coast Monday into Monday evening.

This is not a classic "ocean effect" setup but rather "ocean
enhancement" due to NNE flow over coastal front. If you look at
forecast soundings, they certainly are not very impressive with
very shallow mixing layer (less than 2,000 ft) and not much in
way of ocean-induced CAPE. Focus for activity is coastal front
which will move onshore overnight and meander just inland Monday
into Monday evening. It is this boundary which is the key to
the forecast - including temperatures (teens on west side and
20s/lower 30s to east), location of bands of snow showers, and
where they become more persistent (and bring higher snowfall
totals).

Since this is purely a mesoscale event we need to rely heavily
on higher resolution models and ensembles as opposed to coarser
global models. We largely used a combination of SREF, WRF-ARW,
and WRF-NMM to better predict PoPs/QPF/Snow and to depict the
tight gradient that is likely to occur. Of course this means
that we could be off by 5-10 miles which could make a big
difference, but as we get into realm of more high-res models
(HRRR, RAP) we can further refine the forecast.

Good news is these high-res models and ensembles are very
consistent with their positions of coastal front, extending from
Cape Ann to Boston Harbor and into Plymouth County. It is this
area where we should see 1-3" of snow, although due to banded
nature some areas may only get a dusting while locations a few
miles away get more. Western extent should be Route 128 and
I-195 corridors which may only see flurries.

Focus for more persistent snowfall will be just to west of this
boundary, but especially just south of Boston into Plymouth
County which will have added benefit of enhancement/longer fetch
from NNE (020-030) low level winds. We do not see much in way
of strong lift in dendritic growth zone although there are a
few hours Monday morning where lift intersects with -8 to -10C
(which is favorable with salt nuclei). For these reasons, we
will show a maximum snowfall of 2-4" in these areas and issue a
Winter Weather Advisory. It's certainly possible a few locations
end up receiving a bit more, like 5 or even 6 inches, but those
seem to be outliers at this point. We did note a few 12Z HREF
members showing potential for >5 inches of snow.

For Boston itself, it's a tough call as city will be on edge of
better activity to south and tends not to be favored with
020-030 low level winds (we would like to see more NE winds of at
least 040-050) so we are thinking an inch or two of
accumulation right now.

Meanwhile, not to ignore the rest of SNE, we do think clouds
will expand inland but nothing more than flurries. Model 2-m
temperatures suggest highs in lower to mid 20s, but again milder
to the east of coastal front with highs in lower 30s on Cape
Cod and Islands.

Clearing but not quite as cold Monday night with lows in teens
and lower 20s.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...
Big Picture...

Longwave pattern shows a trough over the Eastern USA and a ridge
over the Western USA through Friday. The flow then trends toward
zonal flow for the weekend.

Short scale pattern shows a trough over the Great Lakes
sweeping east Tuesday but maintaining a progressive axis as it
moves across New England Wednesday. Upper ridge then builds over
the Eastern USA and West Atlantic waters Friday through Sunday.

Upper height fields are similar through Wednesday, with differences
appearing after that. The GFS is fastest in moving the upper trough
past New England and also is more amplified with upper shortwave
moving over the area Friday night-Saturday. The ECMWF is slowest.
All models show building heights through the weekend. MSLP
fields are now similar in developing low pressure east of New
Jersey Tuesday evening and moving it past Cape Cod Wednesday.
They also show surface high pressure building over the region
Friday through Sunday.

Contour heights suggest cooler temps midweek, then milder values
over next weekend.

Confidence in the forecast is moderate for Tuesday-Wednesday,
building to moderate-high for Friday through Sunday.

Details...

Tuesday-Wednesday...

The 12Z models have moved toward a consensus on the midweek weather
system. Low pressure over the Great Lakes moves east Tuesday, with
precip moving into our area during the afternoon/evening. Upper
heights are higher/milder than average, but eastern Quebec high
pressure maintains a cold air damming signal south through much of
New England. So we expect the precip, when it arrives, to be
snow.

As the supporting upper jet shifts east Tuesday evening, its
right entrance region moves over the Mid-Atlantic coast,
supporting a coastal redevelopment which then moves up the coast
near 40N/70W. This should maintain snow over our area Tuesday
night and early Wednesday. Depending on the exact track, there
may be some mix of rain and snow over Nantucket and parts of
Cape Cod. Snow tapers off Wednesday as the coastal low races off
to Nova Scotia.

QPF ranges from 0.2 to 0.4 inches, with snow-water ratios either
side of 15 to 1, except closer to 12 to 1 along the South
Coast. That suggests an advisory-level snowfall for much of our
area. There is a low chance for slightly higher QPF and
corresponding snowfall, and this will need to be monitored.

Wednesday night-Thursday...

Upper trough moves overhead Thursday morning and then off to the
northeast. Wednesday night and Thursday will be the period of
coldest air. The air will be dry, therefore a fair and cold
day. The air is dry enough for Wednesday night min temps to
reach 10 to 20. Mixing to 925 mb supports Thursday max sfc temps
mid 20s to around 30.

Friday-Saturday-Sunday...

A weak shortwave trough moves across New England on Friday. This may
bring a period of clouds but not enough moisture to consider precip.
Otherwise, southern high pressure builds and should provide a spell
of fair weather. Temps aloft trend higher each day, with support
for 30s Friday, 40s Saturday, and possibly near 50 Sunday.

.AVIATION /03Z MONDAY THROUGH FRIDAY/...
Forecaster Confidence Levels...

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

Short Term /through Monday Night/...

VFR for most of the region tonight. MVFR cigs should regenerate
along the Massachusetts east coast later tonight and expand
farther inland overnight and Monday morning.

Snow showers are expected late tonight in eastern MA, mainly
from Cape Ann to Plymouth County with local IFR conditions at
times. Activity will persist through Monday evening, again
focused along the immediate coast and especially Plymouth
County, with little or no snow farther inland, before improving
to VFR areawide.

KBOS Terminal...Moderate confidence in TAF. It's possible
conditions lower to IFR at times in snow showers Monday, but
lower conditions are expected to remain just offshore and south
of terminal area. Snowfall forecast is for an inch or two.

KBDL Terminal...High confidence in TAF.

Outlook /Tuesday through Friday/...

Tuesday: MVFR/IFR conditions possible. Chance SN.

Tuesday Night: Mainly IFR, with areas MVFR possible. SN likely.

Wednesday: MVFR, with areas IFR possible. Conditions improving
in the afternoon. Breezy. Chance SN.

Wednesday Night: VFR. Breezy.

Thursday through Friday: VFR. Breezy.

.MARINE...
Forecaster Confidence Levels...

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

Short Term /through Monday Night/... High confidence.

Small Craft Advisory winds/seas expected on all but Boston
Harbor and Narragansett Bay. High pressure to our north combined
with low pressure passing well SE will maintain strong N/NE flow
through Monday with building seas offshore, before winds
diminish Monday night.

Bands of ocean effect snow with reduced visibility on E MA
waters will diminish tonight, but more activity is expected
overnight through Monday evening.

Outlook /Tuesday through Friday/...

Tuesday: Winds less than 25 kt. Areas of rough seas. Slight
chance of snow. Local visibility 1 to 3 nm.

Tuesday Night through Wednesday: Winds less than 25 kt. Seas up
to 5 ft. Snow likely, chance of rain. Visibility 1 to 3 nm.

Wednesday Night: Winds less than 25 kt. Seas up to 5 ft. Slight
chance of snow. Visibility 1 to 3 nm.

.HYDROLOGY...
Minor flooding continues along Taunton and Pawcatuck where
Flood Warnings remain posted. We also recently issued a River
Flood Warning for the CT River at Hartford...where very minor
flooding is occurring but nothing more than that is expected.

Colder weather will persist through midweek which will limit
additional runoff, although we should see some building of snow
pack from bands of ocean effect snow in eastern MA Monday and
for much of region Tuesday into Wednesday.

forecast river stages, please visit the Advanced Hydrologic
Prediction Service /AHPS/ graphs on our website.
